Installation – Indoor Sensor 077

Wiring the Indoor Sensor

Run two conductor 18 AWG or similar wire between the Indoor Sensor and the

terminals on the tekmar control. Insert the wires through the hole provided in the

back of the indoor sensor enclosure and connect them to the indoor sensor

terminal block. Do not run the wires parallel to telephone or power lines. If the

indoor sensor wires are located in an area with strong sources of electromagnetic

noise, shielded cable or twisted pair should be used or the wires can be run in a

grounded metal conduit. If using shielded cable, one end of the shield wire should

be connected to the Com-Sen terminals on the control and the other end should

remain free. The shield must not be connected to earth ground. Follow the sensor

testing instructions in this brochure and connect the wires to the control.

Installing the Sensor Front Cover

Place any extra sensor wire into the electrical box. Secure the front cover of the

Indoor Sensor 077 to the electrical box. Ensure the wiring is not pinched or crushed

when installing the front plate.
