The AW-D132 series gas detector is designed for use alone or connected to a fire alarm panel. Small and compact, the design and color make it ideal for use in the home, small commercial properties, and recreational vehicles. It is intended to detect leakage of natural gas (methane gas), town gas, and bottled gas (propane gas). The gas detector can be mounted high (for methane gas) or low (for propane (LPG) gas).
