FIRE PREVENTION FACILITY CONTROL SYSTEM AND FIRE PREVENTION SIGNAL TRANSMISSION METHOD

To operate fire protection facility in a section disconnected by a disconnector without a use of a repeater.SOLUTION: In a building equipped with smoke detectors 13, 23, 33, repeaters 41, 42, 43, a receiver 70, and fire prevention facilities (fire prevention shutters 11, 21, 31 and fire doors 12, 22, 32) forming fire prevention compartments, disconnectors 51, 52, 53 are provided between the repeaters and the receivers, and the repeaters connected to a smoke detector which is short-circuited at the time of fire breakout are configured to be electrically disconnected from the receiver. While each fire protection facility is provided with preliminary detectors 11f, 11r, 21f, 21r, 31f, 31r configured to have a lower sensitivity than the smoke detector, the fire protection facility is operated according to the detection result.SELECTED DRAWING: Figure 1 【課題】断路器によって切り離された区画の防火設備を、中継器を用いることなく作動させるようにする。【解決手段】煙感知器１３，２３，３３、中継器４１，４２，４３、受信機７０、防火区画を形成する防火設備（防火シャッター１１，２１，３１及び防火戸１２，２２，３２）などを備えた建物において、中継器と受信機との間に断路器５１，５２，５３を設け、火災発生時にショートした煙感知器の接続されている中継器を受信機から電気的に切り離すように構成する。それぞれの防火設備に煙感知器よりも感度が低くなるように構成された予備感知器１１ｆ，１１ｒ，２１ｆ，２１ｒ，３１ｆ，３１ｒを設け、その検出結果に応じて防火設備を作動させる。【選択図】 図１
