Description

本発明に係るスプリンクラ消火設備は、火災感知手段と、加圧送水装置と、予作動弁と、該予作動弁の一次側に設けられて基端側に加圧送水装置が接続される一次側配管と、前記予作動弁の二次側に設けられてスプリンクラヘッドが接続される二次側配管と、平常時に前記二次側配管内を負圧にする真空ポンプと、前記二次側配管と前記真空ポンプとを接続する真空配管と、を具備するスプリンクラ消火設備において、前記火災感知手段の作動に基づいて火災判断を行う火災判断手段と、前記火災判断手段の火災判断結果のみに基づいて前記予作動弁を開放する通常モード、あるいは、前記スプリンクラヘッドの開栓を検出するヘッド作動検出手段による前記スプリンクラヘッドの開栓の検出のみに基づいて前記予作動弁を開放する単独モードのいずれかを設定する運転モード設定手段と、を備えたものである。 The sprinkler fire extinguishing equipment according to the present invention includes a fire detection means, a pressurized water feeding device, a pre-acting valve, and a primary side provided on the primary side of the pre-acting valve and connected to the base end side. A pipe, a secondary pipe provided on the secondary side of the pre-acting valve to which the sprinkler head is connected, a vacuum pump for making negative pressure in the secondary pipe in normal times, and the secondary pipe; in sprinkler fire extinguishing facility comprising a vacuum pipe which connects the vacuum pump, and fire determination unit that performs fire determination based on the operation of the fire detection means, on the basis of only fire determination result of the fire determination means normal mode to open the pre-actuated valve, or alone mode to open the pre-operated valve the sprinkler on the basis of only the detection of the cap removal of the head by the head operation detecting means for detecting the unplugging of the sprinkler head And operation mode setting means for setting one of, those having a.

また、本発明に係るスプリンクラ消火設備は、前記予作動弁の二次側への流水を検知する流水検出手段を備え、該流水検出手段が前記予作動弁の二次側への流水を検知した際、表示部に放水中であることを表示するものである。 Moreover, the sprinkler fire extinguishing equipment according to the present invention includes a water flow detecting means for detecting water flowing to the secondary side of the pre-acting valve, and the water flow detecting means detects water flowing to the secondary side of the pre-acting valve. time, even for a is that displays that it is in the water discharge on the display unit.

また、本発明は、流水検出手段が予作動弁の二次側への流水を検知した際、表示部に放水中であることを表示することにより、防護区画で火災が発生していることを早期に覚知することができる。 Further, the present invention is when the flowing water detection means detects the water flow to the secondary side of the pre-actuated valve, by a Turkey to display is being water discharge on the display unit, a fire has occurred with a protective partition it Ru can early be SatoshiTomo to the.
