Marine Point Pattern Photoelectric Smoke Detector

Marine Point Pattern Photoelectric Smoke Detector

This model fire detector offers the best life safety protection you can get because it detects the most dangerous type of fire- the slow, smoldering fire that creats a lot of deadly smoke. The advanced sensor sounds the alarm at the first sign of smoke, giving occupants time to put off and escape.

Main Technical Parameters

Monitor Current: ≤ 70uA

Alarm Current:≤20mA

Wind Speed:<5 m/s

Environmental Conditions: temperature ( -10℃-50℃）humidity (≤95%(40±2℃)

Wire System : Two lines

Weight:82g

Working Principle

It use infrared ray scattering principle to detect fires under the condition of smokeless and recieving infrared light is very week, only when the smoke enters,due to the scattering effect, boosting the recieve light signals, when smoke reaches a certain concertration, the alarm signal can be output. To reduce the interference and lower power consumption, emission circuit adopts pulse way to work , to improve the service life of tubes.
