Gas alarm center Crowcon Gasmaster 4

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 and enables system adjustment and testing using buttons on the front panel. The Gasmaster gas detector control panel can operate ‘stand-alone’ or interface with any alarm devices and control systems using a selection of outputs.

Gasmaster ger dig all information du behöver om dina gas- och branddetektorer med ett ögonkast. Den stora flerspråkiga displayen visar gasnivåer från alla detektorer samtidigt och möjliggör systemjustering och testning med knappar på frontpanelen. Gasmaster-gasdetektorns kontrollpanel kan fungera “fristående” eller gränssnitt med alla larmenheter och kontrollsystem med hjälp av ett urval av utgångar.
