This product is a non-coding type smoke detectors,which directly access to working by connecting the 12V DC power supply.
When it is working normally, red LED indicator light will flash three times slowly then go into the normal state of standby, the red LED indicator light flashes a time every 18 seconds and will also always on show during the alarm.
Detector with a pair of output contacts (Open/Closed port is optional). When on alarm,contact closed, after the alarm will be turn off;when the space probe fall to the concentration of smoke alarm products values concentration (standard value for each foot of the weak 3.2% ash, the sensors have a response), the machine will reset to the Normal working condition automatically.
