| 1、根据火灾的特点选择火灾探测器时，应符合下列原则：（１）火灾初期有阴燃阶段，产生大量的烟和少量的热，很少或没有火焰辐射，应选用感烟探测器；（２）火灾发展迅速，产生大量的热、烟和火焰辐射，可选用感温探测器、感烟探测器、火焰探测器或其组合；（３）火灾发展迅速，有强烈的火焰辐射和少量的烟、热，应选用火焰探测器；（４）火灾形成特点不可预料，可进行模拟试验，根据试验结果选择探测器。２、对不同高度的房间，可选择火灾探测器。３、在散发可燃气体、可燃蒸气和可燃液体的场所，宜选用可燃气体可燃液体探测器。４、下列场所宜选用离子感烟探测器或光电感烟探测器：（１）办公楼、教学楼、百货楼的厅堂、办公室、库房等；（２）饭店、旅馆的客房、餐厅、会客室及其他公共活动场所；（３）电子计算机房、通讯机房及其他电气设备的机房以及易产生电器火灾的危险场所；（４）书库、档案库等；（５）空调机房、防排烟机房及有防排烟功能要求的房间或场所；（６）重要的电缆（电线）竖井、配电室等；（７）楼梯间、前室和走廊通道；（８）电影或电视放映室等。 1, choose according to the characteristics of fire detector, shall comply with the following principles: (1) the early fire smoldering stage, produce a lot of smoke and a small amount of heat, little or no flame radiation, should choose the smoke detector; (2) the fire develops rapidly, producing a large amount of heat, smoke and flame radiation, which can be used in the use of heat detectors, smoke detectors, flame detectors, or their combination. (3) fire development is rapid, with intense flame radiation and a small amount of smoke and heat, the fire detector should be chosen. (4) the characteristics of fire formation are unpredictable and can be simulated, and the detector is selected according to the experimental results. For rooms of different heights, fire detectors can be chosen. In places where flammable gas, flammable vapour and flammable liquids are emitted, a combustible gas combustible liquid detector should be chosen. 4, appropriate chooses the following places ionization smoke detector or photoelectric smoke detector (1) the office building, teaching building, department store building hall, office, warehouse, etc.; (2) hotels, hotel rooms, restaurants, reception rooms and other public events; (3) the computer room, the machine room of the communication room and other electrical equipment, and the dangerous places where the electric fire can be easily generated; (4) books, archives, etc. (5) room or place where the air conditioning room, the smoke prevention room and the function of the smoke prevention function are required; (6) vertical shafts, switchrooms, etc. (7) stairway, front room and corridor; (8) movies or television screens. |
