Wireless Zone Sensor

INSTALLATIQN INSTRUCVONS

INTRODUCTION

This wireless

temperature control system, operating

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

central controller for system monitoring.

After mounting each wireless sensor, the Model 7712lT Installation Tool can be used to assign each sensor to a

INSTALLATION Location

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 line-ot- sight transmission range indoors for sensors is approximately

1OOOfeet

Mounting (Fig. 2)

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.

Battery Installation (Fig. 3)

The sensor uses two 3-volt 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 SENSOR WILL NOT OPERATE WtTH ONLY ONE

BATTERY.

Note: Batteries will not seat properly in their compartments if installed incorrectly with regard to polarity. Make sure each battery is fully seated in the compartment and that proper

conted

is being made at each end of the battery.
