Features:1) Non-coded heat detector characteristicsa) The dependent measure distinguish algorithm and self- pursue, self-compensatefunctions, these ensure the detector with very high environment orientation abilityb) The hardware and poly-rank software filter combine together with the single-chipwatchdog wire, it could restrain the influence from interferential signal effectivelyc) It is waterproof, dustproof and shockproof, improve the anti-humidity, anti-sepsisability of the detectord) Combine together with various distinguish modes to improve the alarm reliabilitye) To set two working indicator light symmetrically, easy to installation and confirmfire2) Main technique parametera) Operating temperature: -10+55oCb) Operating humidity: <95%RH (45oC)
