（以海灣產(chǎn)品為例） 底座上有 4 個(gè)導(dǎo)體片，片上帶接線端子，底座上不設(shè)定位卡，便于調(diào)整探測(cè)器報(bào)警確認(rèn)燈的方向。紅外光束感煙探測(cè)器又分為對(duì)射型和反射型兩種。根據(jù)煙粒子對(duì)光線的吸收和散射作用。離子感煙式探測(cè)器是點(diǎn)型探測(cè)器，它是在電離室內(nèi)含有少量放射性物質(zhì)（镅 241），可使電離室內(nèi)空氣成為導(dǎo)體，允許一定電流在兩個(gè)電極之間的空氣中通過(guò)，射線使局部空氣成電離狀態(tài)，經(jīng)電壓作用形成離子流，這就給電離室一個(gè)有效的導(dǎo)電性。在火災(zāi)初期，由于溫度較低，物質(zhì)多處于陰燃階段，所以產(chǎn)生大量煙霧。定溫、差定溫探頭各級(jí)靈敏度探頭的動(dòng)作溫度分別不大于
