1.Operating Voltage:9V 6F22 battery or DC12V2.Static current:3.Alarm current:4.Battery life:About One year5.Power indicator:red LED6.Alarm indication：red LED fast blink7.Level of sound:≥85dB/m8.Operating temperature:-10°C ~+50°C9.Operating Humidity: ≤95%RH10.Alarm output：sound & flash alarm relay output（wired output)Wireless output 315MHz or 433MHz11.Emission distance:100m(open area)12.size:Φ106mmx59mm13.Executive criterion:EN1460414.Detecting area:40square meters when installation height between 6-12m;20square meters when installation height within 6 meters.The detector adopts the reflection principle of smoke particles that can reflectinfrared light.The main circuit includes a MCU processing section,an infrared-emittingportion and an infrared receiving portion.Transmitting and receivingdiodes are placed in the optical chamber which can sheild stray light fromoutside interference,but does not affect the smoke getting into the detector.Usually when in a smoke-free environment, infrared signal is very weakWhen smoke enters the optical chamber,due to scattering effect,the infrared signalincreases.when the smoke concentration accumulated reaches to the MCU alarm level,the detector will flash warning lights and warning alarm,meanwhile senfing alarm signalto trigger other devices which connected to it.NOTICE1.Sensitivity testing is recommended once a month to ensure the detector in a normalworking condition.2.Cleaning the dust around the chamber with a soft brush everysix months to ensure thedetection's sensitivity,cut off the power when cleaning.3.Taking out the battery if no use for a long time.
