Crowcon Gasflag - Single Channel Control Panel
This is a control panel from Crowcon for monitoring any 4-20mA flammable, toxic or oxygen gas detector. It features bright alarm LED's and an 80dB sounder (at 1 metre).
Alarm 1, Alarm 2 and Fault relays are fitted for switching external devices such as audible/visual alarms or valves. Additionally, relay contacts are rated 1A 30Vdc maximum. The Crowcon Gasflag operates from 24Vdc and may be supplied either with or without a mains power supply.
Both options are available within this bundle, ensure you select with or without power supply.
Please note: these are not suitable for use with Xgard Types 3 or 4.
The 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.
