Smoke Alarm Independent smoke detector
1.The smoke detector uses the special structure designphotoelectric sensor, the SMD patch processing craft production, has thecharacteristic of high sensitivity, stable and reliable, low power consumption,beautiful appearance and durable, easy to use and so on. The circuit and thepower supply can be self checking, and can be simulated and tested.
The product is suitable for home, store, song and dancehalls, warehouses and other places of fire alarm.

3.Architectural and Engineering Specifications The smokealarm shall be powered by a 9V battery. The unit shall incorporatephotoelectric sensor with nominal sensitivity of 2.06%/ft. The temperatureoperation range shall be between 40°F and 100°F (4°C and 38°C) and the humidityoperation range shall be 5% - 95% relative humidity.
The unit shall provide optional tamper resistance thathelps deter removal of the unit from the wall or ceiling. The alarm shallinclude a test button that will electronically simulate the presence of smokeand cause the unit to go into alarm. This sequence tests the unit’selectronics, battery and horn to ensure proper operation.
The unit shall include a piezoelectric horn that is ratedat 85dB at 10 feet. The unit shall also include a low battery warning utilizinga brief alarm chirp every 30-40 seconds along brief flashed from the safetylight for a minimum of seven (7) days.
The unit shall incorporate one red LED to indicate thealarm’s current status and mode of operation. The red LED will indicate one oftwo conditions: Standby Condition: The red LED will flash every 30-40 secondsto indicate that the smoke alarm is operating properly.
Alarm Condition: When the alarm senses products ofcombustion and goes into alarm, the red LED will flash rapidly (one flash persecond). The rapid flashing LED and pulsating alarm will continue until the airis cleared.
