Abstract

PURPOSE: To shorten the time from the confirmation of a fire to the input of a fire confirmation signal even when one supervisor is allocated by sending out a signal corresponding to how many times a nonlock type switch is pressed successively. CONSTITUTION: Initialization is performed first, for example, by setting a count K indicating the frequency of depression of a push button B1 to 0 and if there is an input from a switch circuit 25 when there is no call from a fire receiver RE to the fire transmitter P11, a timer 26 begins to count and the count K is increased by one. Then, when an MPU 21 judges that an address outputted by the fire receiver RE matches with an address given previously to the fire transmitter P11, the value of the count K is judged at this time. When K=0, the fire transmitter P11 is not pressed even once, so a normalcy signal showing normalcy is sent out to the fire receiver RE. Unless K=0, on the other hand, a signal corresponding to the value of the count K is read out of a ROM 23 and sent out to the fire receiver RE.
