Functions

1. Detection. 
Press detection button, it can fully check the alarm functions. And the alarm light  flashes quickly with a rapid sound.
2. Alarm. 
In the normal environment, The alarm will flash automatically every 10S and  automatically detects the concentration of smoke in the surrounding environment at regular intervals(around 1.6s),If the smoke concentration is close to the alarm value, the alarm starts to perform intelligent calculation, and the alarm indicator light starts to flash. If the calculation result reaches or exceeds the alarm value, the alarm will start the sound-light alarm and start the relay. When the ambient smoke concentration drops below the alarm value, the alarm will automatically return to the normal working state.
3. Output.
Passive contact output. Contact capacity 24V/1A, NC or NO two kinds of output.


Installation

First drill two mounting holes with a diameter of 5mm on the ceiling 43~ 62.5mm apart. Fix the alarm base with the plug and screw. Then connect the power line and output line.install the alarm to the base in the correct direction. Press down and tighten clockwise, finally turn on the power, it works.
