How does it Work?
- Green LED: Flashes every 30 seconds to indicate the unit is operating properly. The green LED will also flash before CO reading is taken and when any button is press.
-
Red LED: When a dangerous level of carbon monoxide will detect the red LED will pulse and a loud alarm pattern will sound. The carbon monoxide alarm pattern is 4 short beeps, followed by 5 seconds of silence, followed by 4 short beeps with a corresponding red LED flash. This cycle will continue for 4 minutes and then change to 1 cycle every minute until the device is reset or the CO is eliminated.
-
Test/Reset button is designed for weekly testing if it works properly and reset the unit during CO alarm.
-
Alerts users when batteries need to replace.
-
This alarm recommends mounting on a wall surface.
Package Includes
- 1 x CO Gas Sensor Detector Carbon Monoxide Poisoning Alarm Detector With LCD Display.
