Document Type and Number:
Japanese Patent JP7237742
Kind Code:
B2
Abstract:
To make it possible to transmit a closing instruction signal, without using a relay, to a fire prevention facility whose capability of receiving a fire prevention signal is disabled.SOLUTION: In a building comprising smoke detectors 13, 23, 33, relays 41, 42, 43, a receiver 70, fire prevention shutters 11, 21, 31 for forming fire prevention sections, fire prevention doors 12, 22, 32, and the like, disconnecting switches 51, 52, 53 are provided between the receiver and the relays to electrically separate from the receiver a relay connected to a smoke detector that detects occurrence of abnormality at the time of a fire breakout. When an electric wire for signal transmission is disconnected by a flame, no fire prevention signal itself can be transmitted. This invention enables a fire prevention shutter in a state incapable of transmitting any closing instruction signal to form a fire prevention section, by transmitting the closing instruction signal to the fire prevention shutter without mediation of the relay by bidirectionally connecting respective adjacent fire prevention shutters using wiring 91 to 98, 91a, 92a, 93a, 94a.SELECTED DRAWING: Figure 4
