The ZG-100 is the new stand alone Combustible Gas 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 it’s own backbox, or with a standard recessed box for semi-fl ush mounting.

There are two versions available. One calibrated for Natural gas, one calibrated for LPG. They can be powered either from 230V AC mains, or from a DC supply (9-28V DC). They have 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 5 volt alarm output capable of supplying 200mA. They have power, fault & alarm indications, as well as a control button for mute (press) and reset (Press & hold for 5 seconds).
