Abstract

PURPOSE:To provide a guiding lamp device which does not actuate a lamp blinking unit and actuates only a guiding sound unit. CONSTITUTION:When the break-out of a fire is detected by an automatic fire alarm, a high frequency alternating current is induced at a secondary winding Tr2b of an inverter transformer Tr2. When no smoke is detected by a smoke sensor 49, the relay contacts Ry2S1 and Ry2S2 are closed so that a xenon lamp 46 is turned on with flashing. At the same time, a guiding tone is produced. When the sensor 49 detects the smoke and a switch 50 is opened, a lamp blinking unit 44 stops the output of a pulse and does not turn the lamp 46. Then, no power is supplied to a guiding tone unit 51 from a battery B2 and the operation of the unit 51 is also stopped. When an emergency broadcast is supplied to the unit 51, only this unit works and the unit 44 has no blinking, and only emergency broadcast is transmitted.

An inspection switch 7 is connected between the terminal block 1 and the lighting unit 4, and a fuse 8, a battery 9 and a charging monitor 10 are connected to the input side of the lighting unit 4.
The configurations of the ballast 3 and the lighting unit 4 themselves, or the switching configuration between the ballast 3 and the lighting unit 4 are well known to those skilled in the art.

Further, a lamp blinking unit 11 is connected to the output side of the terminal block 1, a xenon lamp 12 is connected to the output side of the lamp blinking unit 11, and a fuse 13 and a battery 14 are connected to the input side. Are connected.

Further, a guide sound unit 15 is connected to the output side of the terminal block 1, a speaker 16 is connected to the output side of the guide sound unit 15, and a fuse 17 and a battery 18 are connected to the input side. Are connected.

The lamp blinking unit 11 and the guide sound unit 15 are connected via a terminal block 21 to a blink signal device 22 and a guide sound signal device 23 of a guide light signal device which responds to an automatic fire alarm 24. There is.

A relay 25 is connected to the guide sound unit 15, and the relay 25 is connected to a guide light 27 on the upper floor and a guide light 28 on the lower floor with respect to the evacuation stairs, for example, via a terminal block 26. A smoke detector 29 is connected to the guide light 28 on the floor directly below.

Further, an emergency broadcast device 30 is connected to the guide sound signal device 23, and this emergency broadcast device 30 is provided with a speaker separate from the speaker 16 of the guide sound unit 15, and, for example, an emergency broadcast is broadcast all over the building. Do.

When an abnormality such as a fire occurs, the flashing signal device 22 and the guide sound signal device 23 send a signal of abnormal condition to the lamp flashing unit 11 and the guide sound unit 15, for example, by setting a DC 24V signal to 0V. The xenon lamp 12 is output and the xenon lamp 12 is blinked, and an induction sound is generated from the speaker 16.

Further, according to the provisions of the Fire Service Act, it is installed at a place where a fire is occurring or a position where it can be guided to a place where a fire is occurring. The induction sound from the speaker 16 must be stopped. It is also desirable to stop the blinking light of the xenon lamp 12.

Therefore, when smoke is detected by the smoke detector 29, the voltage between the terminals a and b of the guide sound unit 15 is set to 0, and the guide sound unit 15 stops the guide sound from the speaker 16. ing. Further, by setting the output voltage between the terminals c and d of the guiding sound unit 15 to 0, the lamp blinking unit 11

[0012]

However, the lamp blinking unit 11 stops the blinking of the xenon lamp 12 and the guide sound unit 15 stops the guide sound from the speaker 16, for example, all at once in an emergency. When broadcasting, not only the stop state of the guiding sound unit 15 is reset, but also the stop state of the lamp blinking unit 11 is reset, which causes a problem that the xenon lamp 12 blinks.

The reason why the xenon lamp 12 starts to blink again is that the level of the guide sound is lowered in order to avoid interference between the guide sound and the emergency broadcast during the emergency broadcast from the emergency broadcast device 30 in the past. I'm trying to stop it.

As means for doing so, for example, a signal according to the emergency broadcast from the emergency broadcast device 30 resets the guide sound signal device 23, that is, the automatic fire alarm 24 makes no fire alarm signal. I have to. Therefore, in this case, the blinking light of the xenon lamp 12 is also stopped via the relay 25. Further, after the flickering of the xenon lamp 12 and the guidance sound of the guidance sound unit 15, before the smoke detector 29 detects smoke, the guidance sound of the guidance sound unit 15 and the blinking of the xenon lamp 12 are configured as described above. The light is stopped and the emergency broadcast of the emergency broadcast device 30 is effectively performed.

However, after the smoke detector 29 detects smoke, by resetting the guiding sound signal device 23,
The guiding sound unit 15 inverts the output voltage between the terminals c and d,
The lamp blinking unit 11 is again operated via the relay 25.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a guide light device in which the lamp blinking unit is not operated even if only the guide sound unit is operated.

[0017]

Although the evacuation route, the display board, the lamp for lighting, the ballast, the lighting unit and the like are omitted in FIG. 1, they may be appropriately added.

Next, the operation of the above embodiment will be described.

First, at a normal time when a fire or the like does not occur, an automatic fire alarm or the like does not input a DC24V emergency signal, so that the relay contact Ry1S is a diode.
Connect D1 and battery B1.

In this state, the voltage of the commercial AC power source E is stepped down by the transformer Tr1, full-wave rectified by the full-wave rectification circuit 41, and made constant by the Zener diode ZD1 to charge the battery B1. When the battery B1 is charged, there is a potential difference between both terminals of the resistor R1.

When the smoke detector 49 detects smoke in this state and the switch 50 is opened, the relay contacts Ry2S1 and Ry2S2 are opened, and the control circuit 45 triggers the gate of the thyristor Th2 of the lamp flashing unit 44 from the control circuit 45. Since the signal is not supplied, the lamp blinking unit 44 stops the pulse output and does not turn on the xenon lamp 46.

Further, since the guide sound unit 51 is not supplied with electric power from the battery B2, the guide sound unit 51 also stops operating.

When an emergency broadcast is performed in any state, the guide sound unit 51 stops operating, or
