Networking type smoke alarm technology parameters
Power supply: DC9V ~ DC28V.
Current: static current alarm current ≤ 45mA ≤ 200uA.
Operating temperature: -10 ℃ ~ +50 ℃.
Relative humidity: ≤ 95%RH (40 ± 2 ℃).
The alarm sounds: ≥ 80dB/m.
Output type: relay passive contact (NO/NC output contact capacity can be set), 1A/24VDC, the factory default output are normally closed mode.
Smoke sensitivity: 0.15 ~ 0.3dB/m.
Networking type smoke alarm principle
Under normal circumstances, the detector about every 5-6 seconds indicating exhibit of lanterns shiny look. Automatic detection of smoke concentration and temperature change in the surrounding environment of the detector, and according to the use environment for automatic sensitivity compensation. When the smoke concentration or temperature is close to the alarm value, speed up the operation of intelligent detector smoke concentration or temperature trend, at the same time the alarm indicator light starts to flash. If the calculation results meet or exceed the alarm value, the detector red LED light remains light, sound, and start the relay output. When the restoration of the environment in the smoke or temperature to normal state, the detector automatically return to normal working condition.
