Loud 85dB Alarm
Power, Fault & Alarm Indicator
Two Phases Alarms
Test/Silence Function
Concentration LED Display
Mains/DC Power Selectable


The Standalone CO Detector has been designed with the same dimensions as a standard 2 gang fitting, so it can be installed either surface mounted with it’s own backbox, or with a standard recessed box for semi-flush mounting.

The unit can be powered either from 230V AC mains, or from a DC supply (9-28V DC).

It has a built in bar graph display to show the current CO level reading, and has a 2 stage relay output which operates at first alarm level (100ppm) & second alarm level (200ppm). There is also a 5 volt alarm output capable of supplying 200mA.

Power, fault & alarm indications are provided, as well as a control button for mute (press) and reset (press & hold for 5 seconds).
