The display unit 80 is composed of LEDs but is arranged in an array of dot matrix and is connected to be controlled by the CPU U6, and is configured to display various control and input states of the receiver.

Referring to the operation of the fire-receiving receiver according to the present invention having the above-described configuration is as follows.

First, a monitoring signal for each line is input from the sensor input unit 30 in the CPU U6 of the CPU circuit unit 10 to monitor the fire and disconnection state. If there is no abnormality, the fire monitoring state is maintained and the display unit 80 is displayed. Turn on the AC power lamp and the normal lamp of the voltage display.

Here, the detector input unit 30 compares the fire / disconnection reference voltage with each line (F1) in the OP-AMP (U8 to U17) corresponding to each line for the monitoring signal input to each line (F1 to F10). ~ F10) Fire / break status is monitored.

When the detector operates in such a fire monitoring state and an abnormal signal is generated from the detector input unit 30, when it is set in a non-accumulated state, the fire light and the operation of the corresponding line (circuit) are controlled through the control of the CPU (U6) programmed by firmware. The main alarm bell, the earth alarm bell, the induction lamp relay, and the fire contact relay are switched to output and display the main alarm bell, the earth alarm bell, the induction lamp contact point, and the fire contact point.

In addition, when an abnormal signal is generated from the sensor input unit 30 and the accumulation state is set, the control unit of the CPU U6 lights up the accumulation light and the operation line of the corresponding line through the control of the CPU U6, and outputs the main sound and the main bell. In the second operation of the detector, accumulate lights are turned off and the fire lights are turned on, and earth alarms, induction light contacts, and fire contact points are output.

In this case, according to the present invention, the memory communication unit 60 interfaced with the CPU circuit unit 10 is connected to store various event history information generated in the receiver in the memory unit 61 in real time under the control of the memory controller 62.

On the other hand, the present invention can perform a circuit operation test, earth seedling output release / recovery test, disconnection disconnection / recovery test, battery charge / discharge test, etc. to check whether the operation of the receiver is kept stable, Unlike the prior art, which used only a method of adding a component on a circuit or removing a component on a circuit and a hardware method, the CPU circuit unit 10 and the AD-KEY circuit provided for program control through incorporation of firmware. By using the switch unit 70 configured to be connected to each other, a simple key operation can easily perform a state or multiple function check for each line, and the following features can be described.

In the case of performing a circuit operation test (continuity), the circuit operation test switch provided in the switch unit 70 is pressed to create an operation test state in the stockpile. At this time, the line disconnection lamp of line 1 blinks, and the switch unit 70 Press the circuit selection switch at to select the desired line (F1 ~ F10) and then press the circuit determination switch to operate the desired line.The CPU (U6) recognizes and checks the circuit operation so that only the existing selector switch (hardware) is used to test the circuit operation. Compared to a case of performing a line break check, a simple switch operation can be used to perform a test, as well as a logic circuit implementation and accuracy can be improved through a CPU (U6) with firmware.

In the case of setting the earth seedling output cancellation / recovery, this is a method used when setting a line that does not want the earth seedling output. When the earth alarm stop switch is pressed for about 5 seconds in the switch unit 70, all indicators are turned off. The disconnection (yellow) of 1 (F1) flashes, and when the desired circuits F1 to F10 are selected by using the circuit selection switch and the circuit confirming switch in the switch unit 70 in the same manner as the above-described circuit operation test. The operation (red) light of the line is turned on, and after selecting the desired line and pressing the recovery switch for about 5 seconds, the setting is completed, and the CPU (U6) recognizes and checks it to operate the corresponding line set by the user. It will be controlled so as not to output earth alarm.

Then, after the ground alarm output release setting as described above, by using the circuit selection switch and the circuit determination switch in the switch unit 70 to select the desired line (F1 ~ F10) to turn off the operation (red) of the corresponding line, etc. Press and hold the recovery switch for about 5 seconds to reset the global seedling output.

That is, in the present invention, by removing (cutting) the diode (D5) from the existing PCB (substrate) to release the earth seedling output or remove the circuit relay (RY1) to eliminate the circuit completely by a simple key operation compared to the way you do not want You can disable / restore the corresponding global seedling output.

In case of setting the disconnection check / recovery of line disconnection, this method is used to set the disconnection check of the line.If the accumulation / accumulation switch is pressed in the switch section for about 5 seconds, the CPU (U6) Recognizing this, all indicators are turned off and the operation (red) of line 1 blinks. In this case, if the desired line is selected by using the circuit selection switch and the circuit confirming switch in the same manner as the above circuit operation test, the corresponding line is disconnected. (Yellow) lights up, and after selecting the desired lines, press the recovery switch for about 5 seconds to complete the setting, and the CPU (U6) recognizes and checks the line, even if a line break occurs for the corresponding lines set by the user. Control is performed so that disconnection check [disconnection (yellow) light is on] is not performed.

Then, after setting the line disconnection check as described above, by using the circuit selection switch and the circuit determination switch in the switch unit 70 to select the desired line (F1 ~ F10) to turn off the disconnection (yellow) of the corresponding line, Pressing the recovery switch for about 5 seconds will reset the disconnection check.

That is, in the present invention, it is possible to release / restore the line break check by simple key operation, compared to the method of releasing the state of the line break by installing a termination resistor in the existing spare circuit terminal.

When the battery charge / discharge test is performed, one watt resistor 53 is charged or discharged through the intersection of the charge / discharge cross relay LS6 in the charge / discharge cross circuit 52 during charging or discharging. It is used by crossing with a dedicated resistor, and at this time, the charging / discharging current is flowed to the watt resistor 53 side according to the crossing state of the watt resistor to facilitate the charge / discharge test of the battery.

In other words, in the present invention, by using one watt resistor 53 as a charge / discharge combined resistance and connecting the charge / discharge cross relay (LS6) to cross use for charge and discharge purposes, while reducing the use parts compared to the conventional, Since the control in the CPU U6 to which the firmware is incorporated is performed together, the battery charge / discharge test can be made more efficient.

Furthermore, in the present invention, it is possible to lock and use each switch of the switch unit 70 to prevent malfunctions or malfunctions that may occur due to mischief of the children, and the switch unit 70 may weaken the circuit determination switch SW8. When pressed for 5 seconds, the CPU U6 recognizes this and sets the switch lock of the switch unit 70. At this time, the switch attention light is turned on.

In this state, the lock function of the switch unit 70 is controlled so that the key function of each switch is not executed. At this time, the CPU (U6) performs the fire monitoring normally even in the switch lock setting state, and when the fire signal is input, the switch It will control to unlock automatically.

Then, in the switch lock setting state, pressing the circuit confirmation switch SW8 again for about 5 seconds may release the switch lock setting.

In the foregoing description, it should be understood that those skilled in the art can make modifications and changes to the present invention without changing the gist of the present invention as merely illustrative of a preferred embodiment of the present invention.
