Mounting Location

The ability of the transmitter to sense the target gas depends greatly upon the proper selection of the mounting location. This transmitter monitors the area around it by sampling the air that passes by the sensor. Since the sensor is mounted inside a housing, air must diffuse through the intake vent and pass by the sensor on its way out of the exhaust vent. Therefore, the transmitter should be positioned where it can sample air that contains a target gas concentration representative of the average value in that area.

• When determining the mounting location, give special consideration to the following guidelines.
• Use one sensor per target gas for each area to be covered.
• Always prioritize locations with the highest occupation density.
• The types of gases each unit is designed to monitor have varying densities. For CO, NO2, and O2, mount the unit at the average breathing height – approximately 5 to 7 feet from the floor. For CH4 and H2, mount the unit at or near the ceiling. For C3H8, mount the unit 12 to 18 inches above the floor.
• Avoid mounting locations that would not be representative of the average gas value in that area. These include but are not limited to locations near doorways, fans, ventilation inlets and outlets, and areas with air velocities in excess of 3.3 ft/s (1 m/s).
• Avoid locations that would allow direct contact with water. Mounting the unit near outside garage doors may allow rain to hit the unit when the door is open.
• Avoid locations that are directly in the outlet air vents of heaters or air conditioners.
• Avoid mounting locations with normal ambient temperatures below -4°F (-20°C) or above 122°F (50°C).
• Do not allow exhaust from engines to flow directly on the unit. Each unit is designed to sense gas concentrations that are 300 to 1000 times less concentrated than the gas levels found in engine exhaust. Also, engine exhaust contains high levels of other components. These components can shorten the useful life of the sensor if they contact the sensor before being diluted by the room air volume.
• Avoid mounting locations where the unit may be hit by passing vehicles. If the unit must be mounted in these locations, provide a shielding cage around the unit for protection.
• Do not restrict the air flow to the unit housing.
• Do not mount the unit in a corner.
• Do not mount the unit near containers of chemicals such as gasoline, kerosene, alcohol, or other cleaning fluids. High level concentrations of these chemicals may be mistaken as the target gas by the sensor and cause false readings. Also, some welding gases may cause false readings.
