The Natural Gas Detector is a low voltage electronic detector of natural gases. This detector is designed for connection to Fire Alarm/Burglary Control Panels. You can install it in buildings in non-hazardous locations such as residences, retail stores, office buildings, and institutional buildings. It has been designed to detect methane (natural gas) and propane (LP) gas. It is NOT designed to detect smoke, fire or carbon monoxide.

• Designed to meet UL standard 2075 for the Standard For Safety for Gas and Vapor Detector and Sensors
• Sensitivity tested based on UL 1484 Standard for Residential Gas Detectors
• Surface mounts to a wall using the supplied enclosure rear housing
• Flush mounts in a 2 x 4 (1-3/4 inch deep minimum) single gang switch, or handy electrical box
• Small, low profile, attractive unit in a white plastic case
• Can be self-restoring or latching
• Test & Reset switch conducts internal tests and actuates alarm relay
• Solid State Electronic sensors: no maintenance or recalibration
• N.O. or N.C. SPST Alarm Relay and N.C. SPST Trouble relay to connect to Alarm Control Panels
• Optional Buzzer: Produces repeating loud tone bursts during alarm, and chirps if sensor trouble is found
• Made in USA

Installation:

With the Natural Gas Detector faceplate mounted on the enclosure’s rear-housing, you can surface mount the unit on a wall. A thin mid-plate enclosure component is also supplied with the detector to mount it on a 2 x 4 inch (5.08cm x 10.16 cm) switch box – single-gang or “handy,” provided by the installer.

Location:

A Natural 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 it in a corner. Also do NOT mount it the 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 detector 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.
