Sensors must be powered according to the instruction manual and be within the cable length from the control unit.

• Do not mount in areas of high heat, direct solar heat, wetness, dampness, or where condensation may form on the sensor.
• Do not mount to piping or any structure subject to vibration.For perimeter detection, place sensors around the area in question to monitor the entire space.
• For point detection, place a sensor(s) at a point where you are concerned about a leak, i.e. at the compressor.
• For heavier than air gases, place sensors close to the ground.
• To help prevent false alarms from stray gas particles such as Volatile Organic Compounds (VOCs), mount sensors 24" to 26" from the floor.
• For lighter than air gases, place sensors high on the walls or ceiling, but convenient for maintenance. Note: Ammonia is lighter than air at normal temperature but heavier in a cold room.
• Take room shape into consideration and mount sensors downstream of any air flow.
• In hot rooms, hot air rises to form a barrier below the ceiling and prevents gas from getting to a ceiling-mounted sensor.  Mount sensors out of traffic flow areas to prevent bumping.
