Zone Sensor Installation

Location Considerations
When selecting a location for the zone sensor, avoid the
following:
• Dead spots, such as behind doors, projection screens,
or in corners that do not allow free air circulation.
• Air drafts from stairwells, outside doors, or
unsectioned hollow walls.
• Airflow from adjacent zones or other units.
• Unheated or uncooled spaces behind the controller,
such as outside walls or unoccupied spaces.
• Concealed pipes, air ducts, or chimneys in partition
spaces behind the controller.
• Areas in the direct airstream of air diffusers
• Exterior walls and other walls that have a temperature
differential between the two sides
• Areas that are close to heat sources such as sunlight,
appliances, concealed pipes, chimneys, or other heat-
generating equipment

Location Considerations for Wireless Zone
Sensors
Placement of the sensor is critical to proper operation (the
receiver is factory mounted). For most installations,
barriers limit proper radio signal strength more than
distance. For best radio transmission range and reliability,
mount the receiver and sensor in line of sight. Where this
is not possible, try to minimize the number of barriers
between the pair of devices. In general, sheetrock walls
and ceiling tiles offer little restriction to the transmission
range for the sensor is as follows:
•

Areas with high humidity
High traffic areas (to reduce accidental damage or
tampering)
Metal barriers between the receiver and the sensor (for
example, plastered walls with metal lathe or metal roof
decks)
Thick, solid concrete walls between the receiver and
the sensor
