The Combustible Gas Detector is a low voltage electronic detector of combustible, heating type gases. This detector is designed for connection to UL Listed Fire Alarm/Burglary Control Panels. Alarm control panels that work on 12 or 24 VDC can provide battery backup to this detector. You can use it in ordinary indoor locations of family living units and office work spaces. It’s also intended for installation in buildings in non-hazardous locations such as residences, retail stores, office buildings, and institutional buildings. This detector has been evaluated by UL for methane (natural gas) and propane (LP) gas. You should NOT use it to detect smoke, fire or carbon monoxide.

A green LED signifies that the Combustible Gas Detector is armed. If it detects gas, the Red LED turns on and the alarm condition relay activates.

Installation:

The three part plastic case allows you to either surface mount this detector or install it over a four-inch square or double gang electrical box, providing a near flush mount.

Location:

A Combustible Gas Detector is usually located in each room (except kitchens or bathrooms) where there are gas appliances or through which gas pipes pass. Do NOT mount the Detector in a corner. Also Do NOT mount it in kitchens or bathrooms – alcohol’s, ammonia, cleaning solvents, paint thinner, gasoline vapors, and aerosol propellants (aerosol cans such as hair spray usually contain a combustible gas) may cause alarms. Do NOT mount it where the normal ambient temperature is below 32° F (0° C) or exceeds 120° F (50° C). If the gas used is natural gas (methane) mount the it on a wall about one foot down from the ceiling. If the gas used is propane (LP), mount the detector on a wall or column one foot above the floor. Use the same spacing as for smoke detectors- 30-foot centers, 900 square feet per detector.
