DatasheetGasflag is a gas detector control panel for monitoring any 4-20mA flammable, toxic or oxygen gas detector. Gasflag is ideally suited to light industrial or commercial applications such as LPG monitoring on garage forecourts, chlorine detection in swimming pool dosing rooms, or methane detection in boiler rooms.
Gasflag features a loud sounder, bright LED indicators and relays for switching external devices such as audible visual alarms or valves.
