Description
High-tech sensor
High accurate electrochemical sensor(the most accurate CO sensor)
infrared photoelectric sensor(the best sensor to detects carbon monoxide while minimizing false alarms)
LCD concentration PPM
Easy to Install
Battery Operated for Convenience
2*1.5V AA dry battery (package notinclude)
-After installing 2 batteries, you can hear the sound of "di", and it starts working normally after 40s. In operation, it displays nothing with a power-saving design. Ultra-long standbytime, low current consumption.
-Press the button “test”, carbon monoxide detector alarms ≧85db, loud enough to alarm you the dangers no matter you’re asleep in the bedroom or watching TV downstairs.
-So easy to install on wherever you stay for long periods: drill the two marked installation holes. Tap the two plastic grommets into holes with a hammer. Mount the bracket to the ceiling by inserting and tightening the supplied screws into plastic grommets.
TIPs in usages:
-How to know it’s working normally:
The green power indicator flashes every 35s.
-How to know it’s broken:
The yellow indicator is always on, the LCD shows “Err” and the machine beeps “didi” every seconds.
-How to know it’s time to change batteries:
The yellow indicator lights 50ms every 35s and “di” at the same time.
Please install the sirens at 0.3~1m below the ceiling because the concentration of carbon monoxide is smaller than that of air.
