DC 9V Home Security Smoke Detector Photoelectric Fire Alarm Sensor with Red LED
The photoelectric detector detects the smoke by a couple of infrared diodes.<br>The principle of detecting is granule in the smoke can reflect infrared light.<br>Infrared diodes are placed in the special chamber.<br>The chamber can shield external light,but dont affect the smoke into it.<br>While have no smoke,the diode can receive very weak infrared light.<br><br>Features:<br>*Test by hand.<br>*Auto reset.<br>*Asic adopted.<br>*Anti-light.<br>*Strong adaptability circumstance.<br>*SMT design,High stability.<br>*All-round detection angle<br>*Suitable for Home, Office, Hotel, etc.<br><br>Specifications:<br>Product Name: photoelectronic smoke detector<br>Operating voltage: DC 9V (6F22 battery)<br>Wireless transmission distance: ≥150m<br>Static current: ≤10uA<br>Alarm current: ≤40mA<br>Indicate alarm: Red LED Flash<br>Sound level: ≥85dB/m(independence or wireless type)<br>Low pressure alarm: 6.8V<br>Operating temperature: -10°C~+60°C<br>Operating humidity: ≤95%RH<br>Detecting Area: 60 square meter<br>Installation height: ≥6m<br>Alarm Output: sound!#!amp!*!amp;flash alarm<br>Size: 113x38mm<br>Color: White<br>Weight: 142g<br>Execute Criterion: EN14604-2005/GB4715-2005<br><br>Package Included:<br>1x Photoelectronic smoke detector (with accessories)<br>1x Manual for photoelectronic smoke detector<br>2x Expansion Plugs<br>2x Screw
