Gasmaster

Our enhanced Gasmaster gas detector control panel has a modular design, so you can customise your control panel with the all the input modules you need for your setting- and none of the ones you don’t, making it an adaptable, cost-effective solution.

Gasmaster is a compact, versatile and powerful gas detection control panel that combines simple operation with an extensive array of input and output functions.

Gasmaster provides all the information you need about your gas and fire detectors at a glance. The large multi-lingual display shows gas levels from all detectors simultaneously, with a user-friendly menu system that is intuitive, making system adjustment and testing using buttons on the front panel a straight forward process requiring minimal training.

The Gasmaster gas detector control panel can operate ‘stand-alone’, or interface with any alarm devices and control systems using a selection of outputs. With the ability to add up to four detectors in virtually any combination, the Gasmaster provides two levels of independent alarm per channel, with remote inhibit and reset capabilities meaning you have full control from anywhere on your site, at all times.
