Description:The photoelectric type smoke part of the detector is based on the photoelectric sensing principle to make up. When fire break out and smoke enters the light-tight box, the particles of smoke scatter the infrared light, and this scattered light goes into the receiving element, there by emitting an electric current, and while the electric current is up to the fixed extent, the fire alarm will be activated. The fixed temperature heat detector part has stabilized performance, long-term durability and least-malfunction are ensured by employing a bimetal mechanism, which meets UL verification.Specification:Rated Voltage: 24V DCStandby Current: 60 mA (max. )Alarm Current: 100 mA (max. )Fixed temperature: 68. 75 centigrade degree( set temp. 55 centigrade degree)Smoke concentration: 15% per meter( set smoke concentranion 10% )Start-Up time: Smoke detector within 30 sec.Heat detector within 300 sec.
