GS911K Gas Detector
Using the catalytic sensor inside it, the GS911K detector detects the presence of
explosive gas such as: Methane, LPG, with trip sensitivity calibrated to 10% of Lower
Explosion Limit, and can activate solenoid valves, sirens and any other signal or alarm
handling device, by means of the built-in relay.
A series of technical features make this gas detector extremely versatile, reliable,
accurate, and safe.
The internal jumper makes it possible to select the relay impulse functioning, to connect
manual reset solenoid valves, or the continuous functioning, to activate class “A” solenoid
valves and sirens.
The relay, free of voltage, allows installation of multiple detectors on a single solenoid
valve ensuring control of multiple dangerous environments.
The detector is complete with a special circuit that controls the catalytic sensor’s efficiency
level, and signals any possible fault.
The external container has an IP42 protection degree.
These features make the GS911K reliable for civil environment safety.
