WIRELESS FIRE ALARM FOR WIRELESS INTERLOCKING ALARM, AND WIRELESS FIRE ALARM SYSTEM

摘要

PROBLEM TO BE SOLVED: To prevent such a phenomenon that any communication failure is caused due to the overlapping of transmitted interlocking control signals, and that interlocking alarm is not available since wireless signals are simultaneously relay-transmitted by a plurality of fire alarms.;SOLUTION: A relay delay time based on the product of a registration number stored in a setting storage means 13 and a predetermined unit time is calculated, and in receiving an interlocking control signal, a wireless communication control means 15 makes an alarm control means 16 start interlocking alarm, and relay-transmits the received fire signal after the lapse of the calculated relay delay time.;COPYRIGHT: (C)2008,JPO&INPIT
