清除已经积累的灰尘或污物将重新获得最佳的探测效果，如果灰尘和污物部分包围一个离子探测器烟室，烟微粒就可能达不到电离室，这只探测器就变得更灵敏，极易产生误报。再比如各种光电探测器，灰尘和油污的积累将减少光的强度，因而各种光散射探测器将变得不太灵敏；而各种光衰减型探测器将变得更灵敏。对于火焰探测器的灵敏度也会因透镜上灰尘和污物的积累而受影响，所有这些都说明定期清洗是必要的。定期地对火灾探测器进行清洗维修，就能延长其使用寿命。对出故障的火灾探测器不究原因，就进行更换，毫无经济性可言。用粗劣的手段进行修复只能造成出故障的火灾探测器一时正常恢复的假象，其隐患更为严重。

Cleaning up accumulated dust or dirt will get the best detection effect. If dust and dirt partially encircle an ion detector smoke chamber, smoke particles may not reach the ionization chamber, which makes the detector more sensitive and prone to cause false positives. For example, a variety of photoelectric detector, dust and oil accumulation will reduce the intensity of light, so all kinds of light scattering detectors will become less sensitive; and all kinds of light attenuation detector will become more sensitive. The sensitivity of the flame detector will also be affected by the accumulation of dust and dirt on the lens, all of which indicate that regular cleaning is necessary. The service life of the fire detector can be prolonged by regular cleaning and maintenance of the fire detector. There is no reason for the failure of the fire detector, and it will be replaced without the economy. By means of poor repair can cause a fire detector fault a normal appearance, its hidden danger is more serious.
