The Standalone Combustible Gas 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.

There are two versions available. One calibrated for Natural gasand the other calibrated for LPG. Each unit can be powered either from 230V AC mains, or from a DC supply (9-28V DC).

The unit has a built in bar graph display to show the current gas level as a %LEL reading, and has a 2 stage relay output which operates at first alarm level (10%LEL) & second alarm level (25%LEL). There is also a 5V 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).
