In addition to the output terminal for general control as described above, the above signal device also has another output terminal equipped with a photoelectric automatic flasher so that it can be turned on only at night even during normal times, and further reduces the number of lights. A dimming signal output terminal is also provided to output a dimming signal in preparation for optical type use. This signal device is installed in a control room where fire prevention objects can be managed centrally, but in any case, a control switch that is turned off by a transfer signal, etc. is inserted between each output terminal and the power source. are doing.

The present invention provides an indicator light for each output terminal to indicate the operating state of the guide light, so that the operating state of the guide light can be confirmed at the location where the signal device is installed. Further, the use or non-use of each output terminal can be easily distinguished by its indicator light. Furthermore, by using a discharge lamp as the indicator light, it is possible to prevent the relay that directly turns on and off the guide light from malfunctioning, thereby preventing the guide light from being accidentally turned off in an emergency.

The example will be explained below with reference to the figures.

A load relay 14 and its normally closed contact 15 are provided. In this embodiment, since the guide light is not connected to the normally closed contact 15 of the second load relay 14, the second load relay 14 is not connected to the second output terminals 7, 7a, and the second load relay 14 is not connected to the second output terminals 7, 7a.
The system of output terminals 7 and 7a is not used, and the system of first output terminals 6 and 6a is used. 16 is a normal guide light, 17 is a dimming type guide light, and these are selected and used according to the needs of the fire prevention target.
Both may be used together. These guide lights 16 and 17 are connected to the first normally closed contact 13 or the second normally closed contact 15 according to the above-mentioned needs, but they are partially divided and connected to both contacts 13 and 15. You may do so. In this embodiment, the guide lights 16 and 17 are both connected to the first normally closed contact 13, and this contact
It lights up when it is in the ON (closed) state.

The dimming signal output terminals 8 and 8a are directly connected to the dimming guide light 17 without going through the distribution board 11, as shown in FIG. On the other hand, normally, a dimming signal is outputted to turn on the light at a reduced level, and the dimming signal is cut off by a transfer signal or the like to turn on the light at all levels.

Next, the internal circuit configuration of the signal device 1 will be explained. First, the fuse and power indicator light 18 are connected to the power supply 2, and then each output terminal 6, 6
a, 7, 7a, 8, and 8a are each connected in parallel, and further connected to the primary side of a step-down transformer 19. On the secondary side of this transformer 19, a transfer terminal 4 is first connected in series, then a series circuit of a transfer relay 20 and a normally open self-holding contact 21 is connected in parallel, and a lock terminal 5 and a lock terminal 5 are connected in parallel to the secondary side of the transformer 19. A series circuit with relay 22 is connected in parallel. Further, a reset switch 23 is connected in parallel to the self-holding contact 21.

Between one first output terminal 6 and one end of the power source 2, in order from the power source side, there is a normally open type transfer switch 24 of a transfer relay 20, and a collective lighting switch 2 in case of emergency.
5. The lighting switch 26 and the normally open locking switch 27 of the locking relay 22 are connected in series. One of the second output terminals 7 shares the transfer switch 24 and the batch lighting switch 25, and connects in series another lighting switch 26 and another locking switch 27 which are linked to the lighting switch 26. A normally closed flashing contact 28 of a flashing relay (described later) is connected in parallel to the switch 26 and the lock switch 27. One of the dimming signal output terminals 8 shares the transfer switch 24, and a dimming switch 29 interlocked with the reset switch 23 is connected in series. or,
The other first output terminal 6a, second output terminal 7a,
The dimming signal output terminal 8a is directly connected to the other end of the power supply 2. Reference numeral 30 denotes a blinking relay which is branch-connected after the batch lighting switch 25 and is connected in series to the photoelectric automatic blinker 9.

Here, the batch lighting switch 25 is for turning on all the guide lights connected to the signal device 1 at once, the lighting switch 26 is for turning on the guide lights of each system, and the locking switch 27 is for lighting the guide lights of each system. A device that is controlled by a locking relay 22 that is linked to the locking and unlocking of a building, and turns off the guide light when the building is unoccupied due to locking,
The flashing contact 28 automatically flashes photoelectrically when the building is unlocked and the guiding lights of the second output terminals 7, 7a are installed in a place where safety is ensured by daylight even if the building is occupied. Flashing relay 3 by device 9
0, and turns on when there is daylight to turn on and off the lighting switch 26 and locking switch 27.
Regardless of the situation, the guidance lights for that system will be turned off.

31, 32, and 33 are between the output terminals 6 and 6a, respectively;
A second discharge lamp connected between 7 and 7a and between 8 and 8a, formed by a discharge lamp such as a neon lamp,
Stabilizing resistors 34 are connected in series. 35,
36, 37 are respective output terminals 6, 6a, 7, 7a,
A first discharge lamp is connected in parallel to each switch and contact point inserted in the system of 8 and 8a so as to bypass the contact point, and is also formed by a discharge lamp such as a neon lamp, Also stable resistance 38
... are connected in series. The first and second discharge lamps are designed to emit suitably colored light such as blue or red.

Next, the operation of the device of the present invention will be explained. First of all, turn on the reset switch 23 under normal conditions.
Turn on to reset the device. At this time, the information transfer relay 20 is activated, turning on the information transfer switch 24 and the self-holding contact 21, and self-holding. At this time, the dimming switch 29 is interlocked and turned off, so that the dimming signal to the dimming guide light 17 is immediately cut off. and,
Thereafter, the reset switch 23 is turned off to output a dimming signal to the dimming guide light 17 as well.

The operations after reset are as follows: collective lighting switch 25, lighting switch 26, locking switch 2.
The following explanation assumes that all 7 are ON.

(A) Under normal conditions, the automatic fire alarm equipment turns on the transfer terminal 4 and activates the transfer relay 20, so the transfer switch 24 is turned on.

(A-) Therefore, in the system of the first output terminals 6, 6a, the first load relay 12 is connected to the power supply 2 via the transfer switch 24, and its contact 13 is turned OFF, and the guide lights 16, 17 are connected. is off. At this time, the discharge lamps 31 and 35 are
The connection relationship shown in Figure B is obtained, and the first discharge lamp 35
is short-circuited by the information transfer switch 24 and turned off, and the second discharge lamp 31 is supplied with power via the information transfer switch 24 and turned on.

(A-) In the system of the second output terminals 7, 7a, the second load relay 14 is not connected to the second output terminals 7, 7a, so this system is not used and the guide light is not connected. .
At this time, the connection relationship shown in Figure 3B is obtained,
Similarly, the first discharge lamp 36 is turned off and the second discharge lamp 32 is turned on.

(B) In an emergency, the automatic fire alarm equipment turns off the transfer terminal, deactivates the transfer relay 20, and turns off the transfer switch 24 and self-holding contact 21.

(B-) Therefore, in the system of the first output terminals 6, 6a, the connection relationship shown in FIG. 2A is obtained.
That is, the second discharge lamp 31 and the first load relay 12
A parallel circuit with the first discharge lamp 35 is connected in series with the first discharge lamp 35. In this case, the second discharge lamp 3
1 compared to the impedance of the first load relay 1
The coil impedance of No. 2 is sufficiently low, so the first discharge lamp 35 is lit, but most of its drive current flows to the first load relay 12, so the second discharge lamp 31 is not lit. Further, the drive current of the first discharge lamp 35 is very small because it is a discharge lamp, and therefore, this minute drive current is the first discharge lamp as described above.
Even if the current flows to the load relay 12, the first load relay 12 is not activated, the contact 13 is turned on, and the guide lights 16 and 17 connected to this system are lit. That is, the drive current of the first discharge lamp mistakenly turns off the normally closed contact 13 of the first load relay 12.
This prevents a situation in which the guide lights 16 and 17 go out even though it is an emergency.

(B-) In the system of the second output terminals 7 and 7a, the connection relationship is as shown in FIG. 3A. At this time, the first discharge lamp 36 and the second discharge lamp 36 are connected to the power source 2.
Only a series circuit with the discharge lamp 32 is connected, and sufficient voltage is not applied to both the discharge lamps 32 and 36 to light them, so that both are turned off.

As described above, in the system of the first output terminals 6, 6a, when the guide light connected to this system lights up (in the case of B-), the first output terminal of this system
The discharge lamp 35 is lit to indicate that the guide lights 16 and 17 connected to this system are in the lit state. At this time, the first discharge lamp 35 is connected to the guide light 16,
It works as a lighting indicator light that lights up when 17 is turned on. Additionally, when the guide light connected to this system goes out (in the case of A-), the second discharge lamp 31 of this system lights up and the guide lights 16 and 17 connected to this system go out. Indicates the status.
At this time, the second discharge lamp 31 functions as a light-off indicator light that is turned on when the guide lights 16 and 17 are turned off.

Furthermore, in an unused system, that is, a system with second output terminals 7, 7a to which no load relay is connected, when the transfer switch 24 is OFF (B-
), the first discharge lamp 36 and the second discharge lamp 32 of the system are both extinguished, and the system is in an unused state (in such a system, the guide light is neither turned on nor extinguished). ) is displayed.

In addition, in the above explanation, the operation of each guidance light and discharge lamp according to the transfer switch 24 which is turned on and off by the transfer signal from the automatic fire alarm equipment was explained, but this transfer switch 24 When ON is normal, the batch lighting switch 25 is manually operated.
Turning the lighting switch 26 ON and OFF, turning the locking switch 27 ON and OFF using the locking relay 22, or turning on the blinking contact 28 using the blinking relay 30.
Similarly, when the lighting and extinguishing of guide lights are controlled by ON and OFF, the turning on and off of the guide lights of a certain system and the state of non-use of the system can be controlled by the first and second discharge lamps of that system. can be displayed. Further, in this embodiment, the system for the first output terminals 6, 6a is used and the system for the second output terminals 7, 7a is not used, but the use or non-use of these systems may be reversed.
Further, even if both systems are used, the above-described function of displaying the operating status of the first and second discharge lamps remains the same. The first output terminals 6, 6a and the second output terminal 7,
7a is that the former has a lighting switch 26 and a locking switch 27 connected in series, whereas the latter has a blinking contact 28 connected in parallel to the series part of the lighting switch 26 and locking switch 27. Therefore, the latter is advantageous in that the guide light can be automatically controlled by the photoelectric automatic flasher 9.

Next, the system of the dimming signal output terminals 8 and 8a will be explained. When the transfer switch 24 is ON and the dimmer switch 29 is ON, a dimmer signal is output from the dimmer signal output terminals 8 and 8a, and the dimmer guide light 17 functions as a built-in relay means. Current flows through relay 17a. In this case, the dimming type guide light 17 is connected to the system collective lighting switch 25 of the first output terminal 6, the lighting switch 26, and the locking switch 2.
If all three of them are ON, the light is off, but if any of these three are OFF, the light is dimmed.
Then, while the dimming is on, turn on the dimming switch 29.
When set to OFF (positive side), the current (dimming signal) flowing through the relay 17a is cut off and the relay 17a is turned off.
becomes inactive, and the dimming type guide light 17 can be completely turned on. In addition, if the transfer switch 24 is turned off by the transfer signal in an emergency,
Since the current to the first load relay 12 is cut off and the dimming signal is also cut off, the dimming guide light 17 is fully lit.

Also in this system of dimming signal output terminals 8 and 8a, the first discharge lamp 37 and the second discharge lamp 33 are turned on and off by the transfer switch 24 and the dimming switch 29. It operates in the same way as in the case of two output terminals 6 and 7. That is, when the dimming signal is output from the dimming signal output terminal 8, the second discharge lamp 33
lights up to indicate that the dimming signal is being output,
When the dimming signal is interrupted, the first discharge lamp 37 lights up to indicate that the dimming signal is interrupted. When the dimming guide light 17 is not used and the relay 17 serving as a load is not connected to the dimming signal output terminal 8, when at least one of the transfer switch 24 and the dimming switch 29 is OFF, both The discharge lamps 33 and 37 are turned off to indicate that the dimming signal output terminal 8 system is not used.

In this way, the guidance light operation display device of the present invention is
Since the first discharge lamp is connected in parallel to the switch that is turned off by a transfer signal, etc., and the second discharge lamp is connected between the output terminals, it is possible to accurately and centrally display whether the guide lights are turned on or off. Moreover, the state of non-use can also be displayed. In addition, even if the switch is turned OFF and power is supplied from the first discharge lamp to the load relay that operates the guide light, the drive current flowing to the first discharge lamp is small and such drive current is Without activating the relay, it is possible to prevent a malfunction in which the guide light does not turn on even in an emergency.
