The Carbon Monoxide (CO) alarm is supplied with a powered-for-life sealed lithium battery and an RF
interconnect module.

Using the unique house code feature, an interconnected system will sound all alarms when one detects CO.
The alarm has a high performance, proven electrochemical sensor to sense CO presence. The sensor is individually calibrated and tested in Carbon Monoxide (CO) gas to ensure accuracy.

The LCD displays CO level, status messages and icons.

The memory feature records the last CO alarm level and can be useful to check if CO has been present while the homeowner or tenant has been absent from the property.

An easy to use Test/Hush button allows the user to check the alarm. This checks all aspects of the alarm (sensor, electronics, battery and sounder).

The alarm has an “End of Life” indicator which will notify the user when the alarm needs replacing at the end of its 6 year operational life.

  • Proven Electrochemical, 100% calibrated and tested with CO gas to ensure accuracy. CO level is checked every 4 seconds.
  • Meets BS EN 50291:2001.
  • BS EN 50270:1999 (EMC) BS EN 60335-1:1994 (Safety)
  • BS EN 50291:2001
  • Temperature Range -10oC to 40oC
  • Relative Humidity 15% to 95% non condensing
  • When toxic levels of CO are detected, the alarm will sound and the red alarm light will flash and the LCD will display the CO concentration.
  • When in pre alarm the LCD will display a ‘VENTILATE’ message and when in full alarm it will display an ‘EVACUATE’ message.
  • The alarm and LCD will automatically clear when CO gas clears.
  • If an End of Life or Sensor Fault is detected the LCD will display a ‘REPLACE UNIT’ message and indicator light
  • If a low battery is detected the LCD will display a low battery icon warning and indicator light
  • Test/Hush button operation
