Pre-Installation
This section provides the following pre-installation information:
•
Location considerations
•
Height requirements
•
Mounting surfaces
•
Address settings
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:
•
Open range: 2,500 ft (762 m) (packet error rate = 2%)
•
Usable range: 200 ft (61 m)
•
Typical range: 75 ft (23 m)
Receiver
When selecting a receiver location, avoid the following:
•
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
Sensor
When selecting a sensor location, avoid the following:
•
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
•
Areas with high humidity
