Safety First USA Gas Valve Controller (GFRAB) Operation:
  • Loud alarm  at a 10% (LEL) lower explosive level. Methane (natural gas) alarm point varies but is near 10% level.
  • Two minutes of electrical power required for monitor operation.
  • Green LED: power is on, no leak
  • Red LED: alarm goes to a BEEP- BEEP mode,  gas valve controller closes the gas valve to stop gas flow to protected appliances.
  • To reset the unit,  ventilate area to remove un-burned fuel and push red reset button.
Once an explosive gas is detected, this gas monitor sounds alarm and can activate equipment to remove dangerous gas build up in a building. Ex. can activate a ventilation fan.  Gas alarm and gas monitor have easily accessible terminal strips for fast and secure wire connections, backup battery charging, low battery detection and sensor failure alarm.
 
The GFRAB model includes the gas sensor, mounting feet, remote ready, alarm and battery and gas valve shut-off/controller.

Use with .5 inch, .75 inch or 1 inch compatible valves.  Optional battery keeps a pilot light lit in case of power outage.

Each Scentry gas sensor is calibrated in a gaseous atmosphere: calibration sets the alarm to sound at 10% of the lower explosive level
(LEL) of the combustible gas. This is not a carbon monoxide alarm as it has only a combustible gas alarm sensor.

Note: Sensor reacts to concentrations of fumes from Alcohol, Butane, Gasoline, Hydrogen (from Charging battery’s), Kerosene, LP Gas, Propane, and Natural Gas (Methane).
