Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a signaling device for a guide light which is connected to a fire detector and used to control the lighting of the guide light.

Conventional technology Generally, when a shifting signal is generated from an automatic fire alarm equipment receiver due to a malfunction of a fire detector or a break in a signal transmission line, the signaling device is configured to instantly operate and send a flashing signal to the guide light. has been done.

However, in the case of such a false alarm or a non-fire alarm, the flashing of the guide light is synonymous with "a fire outbreak", which causes confusion.

Problems to be Solved by the Invention In order to solve these drawbacks, the present applicant filed a patent application filed in 1983.
-161004 proposes a solution to this problem. This content will be explained based on FIG. First, an automatic fire alarm equipment receiver 1 is provided, and this automatic fire alarm equipment receiver 1 has a built-in b contact (normally closed) 2 that opens when a fire signal occurs. A transfer signal terminal 4 of a signaling device 3 is connected to this b contact 2.

Therefore, ACloo is connected to the power supply terminal 5 of the signal table W3.
A power supply 6 of V is connected, and a transformer 7 is connected to the power supply terminal 5. This transformer 7 steps down the secondary voltage to 24V, and a delay timer 9 constituting a receiving section is connected to its secondary winding 8. A parallel circuit consisting of a switch 10 called Sl and a timer contact 11 called Ta is connected between them. In addition, a locking/lighting terminal 1″2 is installed.
A relay 13, labeled X2, is connected between the lock/illumination terminal 12 and the secondary winding 8.

Next, the power supply terminal 5 is connected to a normally open time limit contact 14 labeled Ta and a simultaneous switch 15, which have a dimming/blinking signal terminal 16, a manual output terminal 17, a locking output terminal 18, and a PC output terminal. Terminal 19 and PC switch terminal 2o are connected. A blinking guide light (not shown) is connected to the dimming/blinking signal terminal 16. The dimming/blinking signal terminal 16 has a switch 21 labeled S4.
The manual output terminal 17 is provided with a switch 22 labeled S3, and the lock output terminal 18 is provided with a normally open relay contact 23 of the relay 11 labeled X2a.
is connected to the PC switch terminal 2o, a relay 24 labeled x3 is connected to the PC output terminal 19, a switch 25 labeled S3 and a normally open relay contact 26 of the relay 11 labeled X2a are connected to the PC output terminal 19. A normally closed relay contact 27 called X3b of the relay 24 connected in parallel is interposed.

Further, a stop switch 28 labeled S5 is connected in parallel to the time limit contact 14. moreover.

The power supply terminal 5 has a normally closed instantaneous contact 29 labeled Tb.
and an indicator lamp 3o designated L2 are connected. In addition,
LL, L3, L4. L5 is an indicator lamp that displays the operating status of each part.

In such a configuration, under normal conditions without a fire signal,
The b contact 2 of the automatic fire alarm equipment receiver 1 is closed. At the start of operation, the switch 10 is closed and the timer 9 is energized, and the timer 9 is self-maintained by the timer contacts 11. Therefore, time-limited contact 1
4 is closed and momentary contact 29 is open. At this time, the -switch 15 is connected to the main circuit side, and the switches 21, 22, and 25 are also closed, so the dimming and
A voltage of AClooV is applied to the blinking signal terminal 16 and other output terminals.

When a fire occurs, the b contact 2 of the automatic fire alarm system receiver 1 opens, and the timer 9 starts a timed operation. At this time, the instantaneous contact 29 closes when the time limit starts, so the indicator lamp 30 lights up. However, since the time limit contact 14 is closed until the time is up,
No operating signals are given to flashing guide lights, etc.

During this time, it is confirmed whether the content of the notification is a false alarm or a non-fire alarm, and if it is a false alarm or a non-fire alarm, the stop switch 28 is closed. As a result, even if the time limit contact 14 opens at the time of time-up, there is no change in the voltage applied to the dimming/blinking signal terminal 16, etc., and no confusion occurs. Of course, the cause of the false alarm is confirmed and countermeasures are taken, and the display lamp 30 and the like are also turned off.

In this way, even if a transfer signal is generated from the automatic fire alarm system receiver due to a malfunction of the fire detector or a break in the signal transmission line, the cause will be confirmed within the time limit and the blinking of the guide light will be stopped. This allows unnecessary confusion to be avoided.

However, since the stop switch 28 is a manual type, if the stop switch 28 is left in the ON state, there will be a transfer signal, the delay timer 9 will time up, and the time limit contact 14 will be activated. Even if it is opened, it becomes impossible to transmit signals to the output terminal side, and there is a serious problem that the original function cannot be achieved.

Means for Solving the Problems A signal hold circuit is provided that allows the stop switch to operate only when a transfer signal from the automatic fire alarm system receiver is being received. As a result, if there is no transfer signal, the stop switch is in a state where it cannot perform its function.

Operation The stop switch is enabled by the signal hold circuit only when a transfer signal is being received from the automatic fire alarm system receiver. Therefore, the state controlled by the stop switch is only when the fire alarm is due to a false alarm, etc., and the stop switch cannot operate in the standby state of the transfer signal, so that the signal transmission in the event of a fire is reliably carried out.

Example An embodiment of the present invention will be described based on FIG.

Components that are the same as those described with reference to FIG. 2 are designated by the same reference numerals, and descriptions thereof will be omitted. First, the stop switch 28 in this embodiment is formed by a relay contact indicated as X4a. The operation of this stop switch 28 is controlled by a signal holding circuit 31. This signal holding circuit 3
1, first connect the relay 32 labeled xl in parallel with the relay 13 labeled x2. Further, in parallel with the relay 13, there is a series circuit consisting of normally closed relay contacts 33 and 86 indicated as Xlb, a release switch 34 indicated as X4, a relay 35 indicated as X4, and a normally open relay contact 36 indicated as X4a. It is connected. and.

A normally open stop operation switch 37 labeled S5 is connected in parallel to the relay contact 36 to constitute the signal hold circuit 31.

In such a configuration, under normal conditions without a fire signal,
The b contact 2 of the automatic fire alarm equipment receiver 1 is closed. At the start of operation, the switch 10 is closed and the timer 9 is energized, and the timer 9 is self-maintained by the timer contacts 11. Therefore, time-limited contact 1
4 is closed and momentary contact 29 is open. At this time, the -switch 15 is connected to the main circuit side, and the switches 21, 22, and 25 are also closed, so the dimming and
A voltage of AClooV is applied to the blinking signal terminal 16 and other output terminals. Such a situation is similar to that described with reference to FIG.

Since the relay 32 is energized, the relay contact 33 is open, and because the relay 35 is not energized, the stop switch 28 is reliably maintained in the open state.

Then, in the event of a fire, automatic fire alarm equipment receiver 1b
Since the contact 2 opens, the timer 9 starts a timed operation. At this time, since the instantaneous contact 29 opens when the time limit starts, the indicator lamp 30 lights up. However, since the time limit contact 14 remains closed until the time limit timer 9 times up, no operation signal is given to the blinking guide light or the like.

At the same time, the relay 32 is de-energized, so the relay contact 33 is closed. Therefore, if the fire signal is a false alarm, the relay 35 is energized by operating the stop operation switch 37 to close it.
Close the stop switch 28. Therefore, even if the time limit timer 9 times up and the time limit contact 14 opens, no signal is transmitted to the output terminal side, so the guide light does not blink.

Of course, when the stop operation switch 3°7 is not operated, the time limit contact 14 opens at the same time as time-up, causing the guide light to blink.

However, as described above, when the stop switch 28 is in the closed state due to the operation of the stop operation switch 37.

When the B contact 2 of the automatic fire alarm system receiver 1 returns and closes, the relay 32 is energized again, which opens the relay contact 33, which cuts off the energization to the relay 37 and opens the stop switch 28. become a state. Therefore, the stop switch 28 has an automatic return function.

Furthermore, when the stop switch 28 is in the closed state as described above, when the release switch 34 is operated, the energization to the relay 35 is cut off.
can be left open.

Effects of the Invention As described above, the present invention provides a time-limited contact and a stop blinking guide light in order to provide a delay function that performs a control operation after a predetermined time after receiving a transfer signal from an automatic fire alarm system receiver. In the case where the switch is equipped with a stop switch, the stop switch can only operate when the transfer signal is being received from the automatic fire alarm system receiver, so the stop switch can continue to operate. It is possible to completely eliminate the possibility of disabling the signal transmission when there is a fire signal, thereby ensuring that the original fire alarm function is achieved while preventing unnecessary confusion from occurring. It is something.
