INTRODUCTION

This wireless 

 sensor is designed for use in a

temperature control system, operating 

in conjunction with a

centrally located Spread Spectrum Receiver (Model 7712RX).
Zone sensors are installed in areas where temperature
control is to be maintained. Ideally, the receiver should be
equidistant from all its assigned zone sensors.

The zone sensor measures temperature and periodically
transmits that information via RF 

 to its assigned

receiver. The sensor also transmits occupant set point
temperature. Other information that can be transmitted
includes special service requests, unique serial number of
sensor, and status of the batteries in the unit.
RF signals from wireless zone sensors are received by a
receiver, which will then send appropriate messages via

communication wires to specific 

 and air conditioning

equipment assigned to it. This information is also sent to a

central controller for system monitoring.

After mounting each wireless sensor, the Model 
Installation Tool can be used to assign each sensor to a

necessary instructions for this are contained  in the
instructions accompanying the 7712lT Installation Tool.

Wireless sensors can be installed anywhere on common
walls and panitions. Operation will not be affected by metal
framing in walls or partitions; however, mounting to solid
metal walls or cabinets may reduce the operating distance

between the zone sensor and the receiver. Typical 
sight transmission range indoors for sensors is approximately

A mounting plate is provided with the sensor. If attached to
the back of the sensor, release it by depressing the ‘locking
tab’ at the bottom center of the mounting plate with the blade

of a screwdriver, and then sliding the plate downward.

Mount the plate on the selected wall or partition with the
VELCRO strips or screws provided. Hooks must point upward
(the plate also has the word ‘TOP’ molded  into the top side).
Position the sensor onto the mounting plate so that the
mounting plate hooks enter the keyhole slots in the back of

the sensor, then slide downward to lock the sensor in place.

The sensor uses two 

 Lithium batteries (supplied).

Remove the sensor cover by squeezing the cover at the top
and bottom and then pulling the cover away.
Install one battery in each compartment in the sensor. THE
