Reference numeral 37 denotes a notification sound generation circuit section that operates when the communication push button switch 11 is turned on, and has the same configuration and operation as the visitor notification sound generation circuit section 26. Note that 38 in the figure is a DC power supply.

Now, FIG. 5 shows a specific circuit showing the connection relationship between the sequential control unit 4 of the relay control panel 1, each remote control relay 3, and the remote control select switches _{SW 1} to _{SW 6} of the main controller 15. A holding circuit 39 formed by a flip-flop is connected to _SW6 . 40

The remote control relay 3 has diodes D ₁ and D ₂ connected in opposite directions to the contacts Ry ₁ ′ and Ry ₂ ′ of the relays Ry ₁ and Ry ₂ of the polarity switching circuit as shown in Fig. 5, and a remote control relay drive. A closed circuit is formed by the thyristor SCR of the circuit 43, and is driven by the outputs of the remote control relay drive circuit 43 and the polarity switching circuit 46 to turn on and off the output contact 5 and control the lighting load 2. The remote control relay 3 uses a latching relay, and the one shown in FIG. 6 shows a magnetic holding type latching relay. Although FIG. 6 shows only one thyristor SCR, one remote control relay 3, and one lighting load 2, for example, eight lighting loads 2 are controlled by the remote control relay control circuit 43.

By sequentially connecting the input terminals 4a, 4b, 4c, . . . , the lighting load 2 can be pattern-controlled according to the size of the building. Here, the pattern illumination refers to various pattern illuminations such as all lights on, all lights off, dimly lit, etc. This pattern illumination is determined by the pattern setting switches 44a to 44d, but the pattern illumination set in advance for each alarm is The respective alarm circuit units 29, 34 to 36 are connected to predetermined switches among the remote control select switches SW ₁ to _{SW 6} so that the operation can be carried out.
Relay contacts r ₂₉ , r ₃₄ to _{r 36} of each relay Ry are connected in parallel. Of course, the relay contact r may be provided independently instead of the remote control select switch SW.

In the circuit shown in FIG. 1, when the fire detector 8 is activated, a detection signal is transmitted from the relay control panel 1 to the main controller 15 or the individual controller 16 via the multi-core cable 17, and the respective alarm units 22 issue an alarm. At the same time, for example, the relay Ry ₂₉ of the fire alarm circuit section 29 of the main controller 15 operates to short-circuit both ends of a predetermined remote control select switch SW ₃ through its relay contact r ₂₉ , and transmits the signal to the relay control panel 1. Transmit to. Then, the relay control panel 1 sequentially operates the control units 4 to drive the remote control relay 3 so as to achieve a predetermined illumination pattern. This lighting pattern allows family members to know that a fire has occurred.

Incidentally, it is of course possible to provide an individual remote control switch for controlling each remote control relay 3 separately in a circuit other than the above-mentioned circuits. In this case, each individual remote control switch 28 is connected to a selector unit 24 provided with remote control select switches _SW1 to _SW6 . select switch

The alarm unit is actuated when the detection signal of the detection means is input, and each lighting load is controlled via each remote control relay to a preset illumination pattern specific to the detection means based on the operation output of the alarm unit. Therefore, the lighting load can be controlled in a pattern with a remote control select switch, eliminating unnecessary lighting of the lighting load and saving energy. Since the pattern illumination is performed, it is easy to see when an emergency situation has occurred, and the effect is that family members can evacuate and respond quickly.

If an individual controller installed in a bedroom, child's room, etc. is used as the controller, evacuation can be performed more quickly and safety can be increased.
