Location Considerations

Placement of the sensor and the receiver is critical to proper operation. 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 of the radio signal throughout the building.
The transmission range for the sensor is as follows:

Address settings
Open range: 2,500 ft (762 m) (packet error rate = 2%)
Usable range: 200 ft (61 m)
Typical range: 75 ft (23 m)
Locations that are outside the operating temperature and humidity range (refer to
"Specifications, " p. 47)
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
Placing the receiver inside metal enclosures
Mounting on rooftop without a careful site evaluation and confirmation
Areas of direct sunlight
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
Drafty areas
Dead spots behind doors, projection screens, or corners
Walls that are subject to high vibration
