The CO200 is the new standalone CO detector from Zeta Alarm Systems. It has been designed with the same dimensions as a standard 2 gang fitting, so can be installed either surface mounted with its own backbox, or with a standard recessed box for semi-flush mounting.

It 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.

It has power, fault & alarm indications, as well as a control button for mute (press) and reset (Press & hold for 5 seconds).
