in

This invention relates to a signal station for a fire alarm system which responds to a fire signal from means of notification of fire occurrence, such as a fire detector, for activating an alarm detector to sound an alarm, and to a signal station of this kind capable of deliver stored messages relating to the precautions to be taken when a fire occurs, etc. in the form of speech through a speech synthesis body.

Investigating fires in buildings, hotels 10, etc. confirms that most large fires could have been avoided when contacting a fire station quickly when a fire begins or when people are more appropriately brought to safety. The main reason for causing such severe 15 difficulties lies in the fact that porters in buildings or hotel staff did not act properly, although the fire alarm system worked perfectly.

Typically, a conventional fire alarm system consists of a signal station which is connected to means of notification of fire occurrence, such as a fire detector, a pushbutton, etc. for receiving a fire signal therefrom, an alarm with a bell, lamp etc. and a control for control of the fire alarm system and related facilities, if necessary. This conventional signal station initiates an alarm ringing and turning on the lamp upon receiving the fire signal, but it does not give instructions on precautions to be taken when a fire occurs, such as the operating procedure for the control. Such procedures are usually described in an instruction book or set out on a panel.

If porters or other staff are inexperienced or untrained in the operation of the signal station or they are shocked, they cannot act quickly and correctly or cannot take the necessary precautions or they operate the signal station incorrectly. For this reason, it is seen that education and training in the precautions that 2

DK 159345 B

must be taken by fire and training in managing the facilities associated with the fire alarm system is very important. At present, however, there is no system for easy and effective training and training of the routines required 5 when a fire occurs. In particular, there is little opportunity to review the management of the equipment and facilities related to the alarm system because the parts are not in daily operation. In addition, it is difficult and therefore not intended to read the instruction manual to remember the routines to be performed in case of fire.

It is first and foremost the object of the present invention to provide a signal station for a fire alarm system which, in the case of a fire signal 15, is able to give notification of necessary routines which have been stored in advance in a storage in the form of voice for to instruct porters or other employees to act quickly and correctly.

Another object of the present invention is that.

20 provide a signal station for a fire alarm system where, upon request, the signal station is able to give messages regarding operating and processing methods for the fire alarm system and related equipment and facilities if necessary, and to provide 25 messages on necessary fire precautions in the form of speech for training and training of porters or other employees.

Finally, the object of the present invention is to provide a signal station for a fire alarm system equipped with message facilities capable of delivering messages for guidance in an emergency.

According to the present invention, in connection with a signal station as described in the preamble section of claim 1, there is provided an addressable store containing in separate positions various coded instructions relating to 3

DK 159345 B

(i) actions to be taken in the event of fire, (ii) control of the fire alarm system facilities, (iii) training the users of the fire alarm system, 5 reading the instructions from the repository in response to predetermined command signals from the processor, a manual data input connected to the processor, for allowing it to generate selected command signals to evoke selected instructions, the manual data input being also adapted to provide the processor with inputs simulating a signal without a real fire, a speech synthesis means associated with the processor and storage and arranged to synthesize speech signals representing the evoked instructions, a speech emitting means which receives the above speech signals and converts them to audio.

The present invention is capable of providing an output signal of any desired message at any desired time, independent of the conditions actually detected. The content of the message thus delivered may be imaginary and may be contradictory to the conditions actually detected. This is necessary in order to perform 25 training using the fire alarm system which is rarely activated.

It is well known to those skilled in the art that CH-A-607 175 discloses an automatically controlled speech delivery means capable of delivering previously stored speech information. Examples of the type of information are warnings and operating instructions. This speech-giving device can be used in systems where acoustic or optical alarms were previously used. With the present invention, such an automatically controlled tabulating device is adapted to a signal station for a fire alarm system in a very special way, and to this

DK 159345 B

4 combination is added the manual data input for training purposes. This is necessary to perform the training using the fire alarm system which is rarely activated.

5 FIG. 14 is a block diagram of another embodiment of a signal station for a fire alarm system according to the present invention.

FIG. 1 is a block diagram of a first preferred embodiment of the invention. A signal station 10 for a fire alarm system has a processor 11 for processing an input signal for controlling various equipment and for message delivery of necessary control thereof, a storage 16 for storing messages to be taken in case of fire, a manual input 15 for generating a signal for requesting messages from processor 11, a speech synthesis means 20 for synthesizing a speech signal for messages delivered from memory 16, a speech emitting means 18 for delivering speech from a speech signal, and a display means 17 to indicate requests. In addition, the signal station 10 has a receiver 12, an alarm 13 and a control 14.

FIG. 2 shows an example of a fire alarm system to which the signal station 10 of the present invention is appropriately used. This fire alarm system has a signal station 10, a signal line 1 which is connected to the signal station 10 and which has wires to various locations in a building, connection circuits 2 are arranged to respective fire blocks and connected to the signal line 1, fire detectors 3a and pushbuttons 3b for manual fire notification operation, which is connected to each of the connection circuits 2 together with identification means and alarm clocks 4 and fire door releasing means 6 which are also connected to each of the connection circuits 2. This fire alarm system further comprises such as related facilities, a fire-35 tap 7, a sprinkler 8, etc., which are operatively associated therewith. A message facility 9 may also be *

DK 159345 B

6, if required, to the signal station 10. It is not always necessary to prescribe all these equipments and facilities, but other equipments or facilities may also be connected if required.

The processor 11, as shown in FIG. 3, a central processor part (CPU) 11a, a ROM memory 11b whose contents do not disappear or can be erased, a free memory RAM memory 11c, an input / output port (I / O PORT) lid and a bus (BUS)

Ile who connects them. ROM 11b stores CPU 11a programs and CPU 11a performs various control operations according to the programs. RAM llc is a storage that is temporarily used to run 15 CPU lla. I / O PORT Fire is used to connect various input / output devices to processor 1, and in the embodiment shown, I / O PORT lid connects receiver 12, manual input control 15, alarm 13, control 14, display means 17 and 20 speech synthesis means 20 to the processor 11 through respective connection circuits. Other equipment or facilities, such as a printer, can also be connected.

Receiver 12 has, as shown in FIG. 3, 25 a receiver circuit 12a connected to the signal line 1 and a connection circuit 12b for input or output of a signal from the receiver circuit 12a to the processor 11. The receiver 12 receives a fire signal from fire detectors 3a, one which gives a message of 30 fire and further receives a block name signal and an identification signal from the connection circuit 2 and the connecting means 4 and an error signal and a normal signal, etc. The nature of the signals different from the fire signal depends on the function of the fire alarm system used and it is not always necessary that the receiver 12 receives all these signals. In a 7

DK 159345 B

fire alarm system with the simplest structure, it is sufficient for the receiver 12 to simply receive the fire signal. The receiver 12 may also have a function for transmitting a signal to the connecting circuit 2, to the fire detectors 3a, etc. The receiving circuit 12a may be omitted depending on the circumstances. In this case, the circuit 12b can be connected directly to the signal line 1.

The manual input 15, for example as shown in FIG. 3, a contact string 15a and a connection circuit 15b, generating a message requesting signal for requesting a message stored in the memory 16, which memory 16 is described in detail below. These messages can be selected and the selection is performed using a set code, e.g. by a closed-non-closed combination of the contact pull. When operating the manual input 15, messages about necessary fire precautions, or messages on operating instructions for the fire alarm system and related equipment can be heard and training can be performed against a fire even under normal conditions. Alternatively, the manual input 15 may be arranged so that the contacts 15a are pre-combined to correspond to the respective codes, so that the 25 codes can be selected by operating a switch or by pressing pushbuttons corresponding to the respective codes. As a further alternative, the manual input 15 may be configured as a keyboard. In the latter case, the loading of simulated 30 fire data for exercise can be easily performed.

The alarm 13 has sound generating means such as a clock and a lamp and is intended to be driven by a signal from the processor 11 which is connected via a connection circuit (not shown).

35 The control 14 has a circuit, switches for transmitting messages to the circuit, a telephone, etc. and 3

DK 159345 B

is intended for manual or automatic control to stop the sound of alarm 14, calls to necessary locations and to activate relevant equipment such as sprinklers, etc. in accordance with an instruction signal from processor 11. This control 14 shown in FIG. In addition, the embodiment is intended to deliver a control confirming signal to the processor 11 as confirmation that requested operations are performed safely corresponding to the function of the control 14. However, the control 14 does not always have to have a function for delivering the operational confirming signal. . The controller 14 can be used independently of the processor 11 without being connected thereto.

The display means 17 comprises a combination of a control panel with signs and an indicator lamp, a single display formed by seven-segment LEDs, a liquid crystal display to mark the name of a block in which the fire occurs, precautions to be carried out = -20, and so on. using signs or symbols on a panel of the signal station. Alternatively, a VIDEO screen may be used as display means 17. In this case, the messages stored in the storage 16 may be displayed simultaneously with or independently of speech synthesis from the speech synthesis means 20. Depending on the conditions, this display means 17 may be omitted from the fire alarm system.

Storage 16 is one or more non-volatile ROM stores of direct access to the storage facility, which stores messages on fire, 30 to be taken on fire, fire alarm system operating instructions, fire drill instructions and indicative notification messages as required. In addition, the memory 16 may have a RAM memory if needed.

Alternatively, although the memory 16 is connected to the speech synthesis means 20 in the illustrated embodiment, the memory 16 may be contained in the processor 11.

DK 159345 B

The storage method of messages to the storage 16 varies depending on the nature of the speech synthesis means and / or the amount of messages. For example, in the case of speech synthesis, the messages are stored with the speech synthesis part 22, which will be described later with reference to FIG.

5, sequentially in the form of speech parameters, and an address table is set up to indicate the start address of each message group or word group.

FIG. 4 shows an example of an address table 10 wherein, for example, a general message "fire occurred in" is stored in an area aQ starting at a start address 100, block names such as "supply room", "storage", "office" etc. are stored respectively in ranges a ^ to ag beginning respectively at the starting addresses 15 200 to 900. In regions b0, bx and b2, messages are stored for measurements taken when a fire occurs. Similar messages for fire drills are stored in areas Cq and c ± and indicative message data is stored in areas dQ to dn. The starting addresses shown in FIG. 4, 20 are provided to facilitate the explanation, but in reality they are selected taking into account the length of the messages. Alternatively, the address table may be provided in ROM 11b and not in storage 16.

The speech synthesis means 20 has, for example, as shown in FIG. 5, a connection circuit 21 connected to a BUS 19 from I / O PORT lid, a speech synthesis part 22 for speech synthesis, a low frequency filter 23 for a speech signal and an amplifier 24. The speech synthesis means 20 is connected to the memory 16, the speech emitting means 18 and processor 11 so that it reads messages from memory 16 in response to an instruction from processor 11 and synthesizes voice signals corresponding to the messages for delivering them in the form of speech from voice emitter 18.

For example, the speech synthesis part 22 has as shown in

FIG. 6, a speech synthesis 22a constituted by a chip LSI

10

DK 159345 B

and a control 22f for controlling speech synthesis. Speech synthesis 22a comprises a sound source 22b, an interpolation circuit 22c, a digital filter 22d and an A / D converter 22e. In speech synthesis portion 22, control 5 22f reads speech parameters constituting a message from the associated address in accordance with an instruction from processor 11, the parameters are sequential inputs to speech synthesis 22a, and a speech signal is synthesized on the basis of an impulse supplied by sound source 10 22b . This speech signal is transmitted to the voice emitting means 18 via the low frequency filter 23 and the amplifier 24. The control 22f emits a recording signal during these operations. Alternatively, this effect of control 22f may be performed by processor 11. In this case, control 22f may be omitted. As another alternative, the control 22f may be integrated with the speech synthesis 22a and, if desired, may also be integrated integrally with the memory 16.

The speech emitting means 18 comprise a speaker 18a located at the signal station 10, and speakers 18b and 18c located at other locations for delivering speech signals as speech. These speakers 18a, 18b, 18c are interchangeably connected according to the content of the messages. Of course, the 25 speakers can be switched using a manual control.

Depending on the conditions, the speakers 18b and 18c can be omitted. In addition to the speaker or speakers, the message equipment can be connected to the speech synthesis means 20 through similar couplers.

FIG. 7 shows another species of a speech synthesis portion 22 having a microprocessor 22i, a ROM 22g, a RAM 22h and a D / A converter 22e. In this speech synthesis section 22, phonematic data of respective sounds recorded by natural speech PCM recording and an editing and synthesis program are stored in ROM 22g. On the other hand, messages are stored as character information in

DK 159345 B

11 the memory 16. The microprocessor 22i reads a message from the memory 16 and associated phonematic data from ROM 22g in accordance with a processor 11 instruction and edits the phonematic data in accordance with the speech and synthesizer program for synthesizing a speech signal. RAM 22h is a memory temporarily used by the microprocessor 22i during the performance of these operations. In the case shown in FIG. 7, the control of the microprocessor 10 22i may be imposed on the processor 11 and the memory 16 and ROM 22g may appear integrated.

The speech synthesis system is not limited to those described above, and other speech synthesis systems may be used in the present invention.

For example, messages that are PCM recorded can be reduced to appropriate words or phrase groups for storage in a memory and read by the processor 11 or a special microprocessor for the purpose of editing and synthesizing speech.

The operation of the fire alarm signal station of the present invention is described below.

FIG. 8 is a flow chart for running a main routine of the processor 11 of the signal station in the embodiment shown. Upon initial monitoring of a fire signal following the installation of the fire alarm system, an initialization 30 of the processor 11 is performed to delete memories and registers to prepare for the execution of various processing processes. The high 30 is performed at a constant speed.

The first operation is a signal line check 31, where it is checked via the receiver 12 whether the signal line 1 (Fig. 2) is functioning normally or is out of order. In a subsequent signal line data input operation 32 35, a signal such as a fire signal and / or an error signal is stored when such signal is obtained from signal line 12

DK 159345B

1, or an operative confirmation signal, when such a signal is output from the control 14, which signal is stored in a buffer, i.e. a predetermined range of RAM 11c, a buffer register (not shown), etc. In a manual data input operation 33, correspondingly, a message requesting signal is stored in a predetermined buffer when such signal is output from the manual input 15.

A data processing function 34 is installed to perform processing of various input data 10 and is shown in detail in FIG. 9. First, a selection is made at 40 to determine if the data input represents a fire signal. If the decision is "yes," a flag marking flag is set in a flag setting such as a predetermined area of RAM llc, a 15 flag flip-flop (not shown), and the block name and identification signal stored in the buffer, is decoded and converted to corresponding block name and identification number and stored in RAM 11c (as shown at 41 and 42 in Figure 9). The block name and identification number thus stored can be further converted into start address data for speech parameters to the corresponding block name and identification number stored in the memory 16.

Next, it is determined at 45 whether an error signal 25 indicates either an error, e.g. an interruption of the signal line, a failure of a power source for the connecting means or an interruption of the fire detectors. If the decision is "yes", an error-flagging flag is set in a flagging means in the same way as in the decision at 40, and a block name with errors is decrypted and stored in RAM 11c (as shown at 46 in Figure 9).

Conversely, if the decision is "no", go one step further without performing the operations described above.

35 A further decision is made at 47 to determine whether a normal signal indicates that they

DK 159345 B

13 related facilities are ready for operation or not, whether there is an inspection signal for an inspection examination, whether there is a function-confirming signal, etc.

If the answer is "yes", flags corresponding to the respective normal signals are set in the corresponding flag setting means and the signal content is decrypted and stored in RAM 11c (as shown at 48 in Fig. 9).

If the answer is "no" to the decision at 40 as to whether the data input is a fire signal, a further decision is made at 43 as to whether there is an input signal, such as a message request signal, etc. from the manual input 15. If the decision is "yes", a manual input flag is put in a flag setting and the contents of the 15 input signal are deciphered and stored in RAM llc. Although this step is simply expressed at 44 as one operation in FIG. 9, the step is performed according to the content of the input signal, i.e. flags are set in corresponding flagging means for respective messages that are requested to be released, such as operating method messages, functional training message, indicative message data, etc. Upon completion of these operations, the program proceeds to the first operation in a final state of this data processing routine. Otherwise, if the decision at 43 is "no," the program divides into a decision point 45 to determine if there is an error signal.

Following the data processing operation 34, a control signal processing operation 35 is performed in accordance with 30 of the main routine. In this step, the respective flag setting means are checked and an activating signal is provided for the alarm 13 and a control signal for the related means such as the fire cock 7, the sprinkler 8 and so on.

In a display executing operation 36, the contents of an input signal, i.e. a fireproof

DK 159345 B

14 nal, an error signal, etc. from RAM 11c and displayed in the form of characters and / or symbols by the display means 17. In cases where a CRT display is connected, a control is also displayed for displaying the same message as the message synthesized by the speech synthesis means 20.

In a voice control operation 37, a speech synthesis control operation is performed for a desired message from the speech synthesis means 20. This operation 10 is shown in detail in FIG. 10. At 50, a decision will first be made as to whether the requested communication is finished. This decision is performed by a check of whether a fire indicating flag and a manual input flag have been set by the operations shown 15 at 41 and 44 in FIG. 9. More precisely, when these flags are in reset positions, namely if they have never been set or in reset positions after performing an operation 52 corresponding to actions to be performed in a fire (hereinafter referred to as "fire operation"), which will be described in detail later, the answer is "yes" and the program distributes to pass the subsequent voice control operation, and processor 11 performs yet another operation of the main routine. However, if none of the flags are in the set position, the answer to the call is "no" and the subsequent voice control operation is performed. This ruling at 50 can be omitted.

At 51, a decision is made as to whether messages to be issued are fire data, such as operation fire data, etc. If the answer is "yes", fire operation is passed and if the answer is "no", the program divides into another decision. At decision point 53, a decision is made as to whether the notifications to be read are notices of operating methods and / or notices of exercise. If the answer is "yes", an operation (as shown at 54) is performed to explain the fire alarm operation fc operation method.

DK 159345 B

The system and the related facilities (in the event that such facilities are not connected, an explanation of them is not required, as will be described in more detail later), and an operation when exercise is performed. If the answer is "no", the program divides itself into another decision. At decision point 56, a decision is made as to whether messages to be sent are indicative messages and if the answer is "yes", an indicative message operation 57 is performed, whereas 10, if the answer is "no," the program is split into another steps of the main routine.

Among the decisions 51, 53, 56, the decision 51 concerning a fire signal is given priority so that the fire operation 52 is carried out as a result of the decision at 15 s when a fire signal is received during the processing of other messages, such as messages regarding operating methods, etc. These decisions at 51, 53 and 56 is performed by checking the flags set by data processing step 34, as in the case of the decision at 50.

In the fire operation 52 shown in FIG. 11, at 60, a decision is made as to whether a fire incident has already been reported. If the decision is "no", fire notification is done. If the decision is "yes", the program proceeds to further decision at 62. This decision at 60 is made by checking a fire reporting flag set in a flag setting after completing a usual message operation 77, which will be described in detail later. Referring to FIG. 12. Further decisions are made in similar ways at 70, 74 and 76 whether the name of a block on fire is read out, whether the usual message is given and whether the block name is given.

In a fire message 61 shown in FIG. 12, 25, a decision is made at 70 whether the name of a block on fire has already been read out. If the answer is

DK 159345B

16 "no", the block name is read from fire data stored in RAM 11c, and a starting address of speech parameters corresponding to the stored block name in the memory 16 is calculated from the read block name. This calculation is performed with reference to the address table, which is located in the storage 16 or in ROM 11b.

Next, at 73, it is decided whether the speech synthesis organ 20 is ready. This is done by checking whether a recording signal is output from the speech synthesis part 22 through a connection 21, as shown in FIG. 5. If the answer is "no (busy)", the program divides into another step in the main routine throughout the subsequent synthesis operation. Processor 11 repeats the run of the main routine until the decision becomes "yes (clear)".

15 If the answer is "yes" or the answer becomes "yes" after repeating the main routine, the decision at 74 as to whether the usual notice has already been made is made at 74.

If the answer is "no", the starting address, e.g., No. 100, is sent by the usual message "fire broke out" for readout from storage 16 to the speech synthesis portion 22, and a start signal is provided thereto for the synthesis of a voice signal to transmit it. usual message (as shown at 75).

25 If the usual message has already been given, a decision will be made at 76 whether the block name is given. If the answer is "no", a start address, for example, No. 200, for "supply room" for readout from the storage 16, is sent to the speech synthesis portion 30 22, and a start signal is output for synthesizing a speech signal to output the block name (as shown at 77 ).

If the block name is already entered, the processor proceeds to the next step without performing the pre-specified operation.

35 Next, a decision is made at 62 whether high wood and local audio signals are stopped, as shown in FIG.

17

DK 159345B

11. The main audio signal comes from a bell in the alarm 13, and the bell is placed in the signal station and the local audio signals come from bells placed in the respective fire blocks. If the answer is "no", instruction such as speech is stopped to stop the main and local audio signals by speech synthesizer 20 by the same procedure as for fire operation 61. This instruction may be, for example, a message such as "set a main audio signal stop switch and a local-10 audio signal stop switch in stop position ".

If the decision at 62 is "yes", a further decision at 64 will be made as to whether the place is confirmed. The latter decision is made by checking the status of a preselected flag in the flag-setting means. When an operator has set a location-confirming switch in the control 14 in the signal station in the "inside" position, the preselected flag has been in a position "1". If the answer is "no," a location-confirming instruction 65 is executed in a similar manner. This instruction may be, for example, a message "turn no ....... or run to the place to execute confirmation. When confirmed, tap a confirmation contact".

If the decision at 64 is "yes," a further 25 determines whether a post-affirmative action has already been taken at 66. This decision is made by checking the position of one of the flag setting means by means of an operational confirmation signal from the control 14, which flag is in the "1" position to indicate that the audio signal stop switch is in the predetermined position.

If the answer is "no", an action scramble 67 is performed after the site verification is performed in the same manner as described above. For example, this instruction may be a message "if fire, contact fire station and escort people to a safe place.

DK 159345 B

18 during operation and return the audio signal stop switch to the predetermined position ".

The fire operation described above is performed in such a way that the processor 11 determines whether the operator has performed the required operations or performed the required actions, and that one or more necessary messages selected from the messages concerning precautions to be performed are executed. when a fire begins, broadcast in the form of speech in accordance with the outcome of the decision. In this operation, the operator can direct necessary operation and perform necessary action. However, it is possible to use a system in which the decision is not executed and in which all messages are repeated sequentially. In this case, it is sufficient merely to use the message's starting address as the output of the speech synthesis means 20 so that the program 11 of the processor 11 can be simplified and the load thereof reduced.

A manual 54 control manual is for 20 explanation of operating method for the fire alarm system and related equipment and facilities. As regards the related equipment and facilities, explanation is given only for the equipment and facilities which require manual control or the explanation may be omitted. Explanation 25 includes information and messages about the status of the fire alarm system and precautions to be taken under normal conditions, in the event of a power failure and in the event of a fire. This explanation is transmitted by a request signal for manual instruction from manual input 15.

A control for exercise 55 is performed in the same way as manual instruction control in the embodiment shown, but it can be performed independently. In this control shown in FIG. 13, it is first decided at 80 whether an exercise start message is complete. If the answer is 35 "no", a message starts 81 about exercise start, such as "Now start exercise operation. A fire signal is given,

DK 159345 B

19 please direct operations in accordance with the instructions ". A fire message 82 is then issued. In contrast, a division of the program for forwarding the aforementioned operation occurs if the decision at 80 is" yes ".

Next, the routine for the fire operation 52 is retrieved, which routine allows the fire precautionary messages to be delivered. Next, at 83, it is determined whether action by fire has been performed. If the answer is "yes", e.g. message "Now Exercise is Ended," as the end of the control (as shown at 84).

From a guidance message 57, a signal about the building's emergency equipment, emergency system, fire warning etc. is given to message facilities in the form of a speech signal. Notification can be given at any time, except 15 during fire or exercise. For example, in hotels, etc., messages can be sent around at the request of concierges. Where a message regarding escorting people to a safe place is stored in the store 16, guidance message can be done correctly in case of fire and also during 20 exercises.

Upon completion of the voice control 37, the processor 11 resets the flag associated with the voice control and is set in the flag setting means when instructions are given to deliver the last messages in the fire operation 52 or control 55 to the exercise and guidance message 57.

Upon completion of voice control, processor 11's main routine returns to signal line check 31. However, if related equipment and facilities, such as automatic fire testing equipment, marking test equipment, a printer, communication equipment, messaging equipment, etc., are connected, the main routine returns to signal line check 31 upon completion of control control. of these equipment and facilities. Where the printer is connected, not only fire data is printed, but also the times when the required controls and actions are performed, so

20 that it is easy to know whether such controls and actions have been performed properly. A clock must be connected for time printing.

Speakers 18a, 18b and 18c in the speech-emitting means 18 are interchangeably connected so that all speakers 18a, 18b and 18c or at least the speaker 18a can be connected in the event of a message, e.g. a fire signal and only the speaker or speakers selected by the manual input 15 can be connected in the remaining cases under the control of the processor 11.

FIG. 14 shows another embodiment of a fire station signal system according to the present invention. In this embodiment, a receiver 15 12, an alarm 13 and a control 14 are arranged separately from a processor 11. The receiver 12 is constructed of separate logic components, such as relays, etc., as in a conventional fire alarm system, and the alarm 13 is controlled by the separate logic components. A processor 201 is connected to the receiver 12 through a connection (not shown) or includes the connection to connect to the receiver 12.

The signal station 10 in the present embodiment can conveniently be used when it is required to further introduce a speech-function function for delivering messages of fire precautions, in a conventional signal station to a fire alarm system.

Processor 11 controls and controls speech synthesis in substantially the same manner as in the first mentioned embodiment, upon receipt of a fire signal. However, in this embodiment, the messages are simply repeated because the control 14 is not connected to the processor 11. Of course, the control 14 can be connected to the processor 11 as in the first embodiment, if it is necessary to select the appropriate messages in determining
