19、tors, flame detectors, or other types of detectors, and the controller itself has “automatic” and “manual” control modes for selection. When in “auto” mode, the controller is in automatic control status.自動(dòng)控制方式時(shí)，當(dāng)同一個(gè)保護(hù)區(qū)內(nèi)只有一種探測(cè)器檢測(cè)到火災(zāi)跡象時(shí)，控制系統(tǒng)發(fā)出火警聲和光信號(hào)，通知有異常情況發(fā)生，而不啟動(dòng)滅火裝置釋放滅火劑。如工作人員確認(rèn)火災(zāi)確實(shí)發(fā)生，確需啟動(dòng)滅火裝置滅火時(shí)，可

20、按下“緊急啟動(dòng)按鈕”，即可啟動(dòng)滅火裝置實(shí)施滅火；當(dāng)有兩種探測(cè)器同時(shí)檢測(cè)到火災(zāi)跡象時(shí)，控制系統(tǒng)發(fā)出聲音信號(hào)，通知有火災(zāi)發(fā)生，有關(guān)人員應(yīng)立即撤離現(xiàn)場(chǎng)，并發(fā)出聯(lián)動(dòng)指令，關(guān)閉風(fēng)機(jī)、防火閥等聯(lián)動(dòng)設(shè)備，經(jīng)過(guò)030s延時(shí)后，控制器發(fā)出滅火信號(hào)，電動(dòng)開(kāi)啟氮?dú)怛?qū)動(dòng)裝置，驅(qū)動(dòng)氣體會(huì)打開(kāi)對(duì)應(yīng)的二氧化碳滅火瓶組實(shí)施滅火；如在控制器延時(shí)過(guò)程中發(fā)現(xiàn)并不需要啟動(dòng)滅火裝置，此時(shí)可按下保護(hù)區(qū)外的或控制器操作面板上的“緊急停止按扭”，即可終止控制滅火指令的發(fā)出。Under the automatic control mode, when only one type of detector detects fire in a pr

No mater which type of detector detects a fire or makes any false alarm, the controller will send out an acousto-optic fire alarm signal only, rather than starting the

26、 fire extinguishing device, and do not pressure the “emergency start button” outside the protection area or on the controller panel to implement fire extinguishing until the fire is confirmed by the staff. Regardless of the control mode, the fire extinguishing device can be initiated by pressing any
