INFRA RED SENSOR TRANSMITTER OPERATION AND INSTALLATION: The infrared sensor is positioned behind

the round IR filter lens. It has a horizontal detection angle of 40 degrees and a detection range of over 30 feet. See

diagram below. The optimum target range is 10 to 15 feet from the Sensor Transmitter. The infrared sensor detects

vehicles, intruders, etc., by sensing their heat and motion. When a vehicle or large warm object moves through the

detection zone, the Infra Red Sensor Transmitter detects the intrusion and transmits a signal to the receiver. When

the battery’s voltage has dropped below the sensor’s required operating voltage, transmissions are sent to the

Receiver until the battery voltage becomes too low to transmit.

First, install a high quality 9-volt alkaline battery in the compartment located in back of the sensor case. Securely

close the battery cover. The Battery will last about six months under normal use. Mount the sensor approximately 2 to

2.5 feet above the ground to a tree, wooden post or side of a building. A Metal Mounting Bracket and Mounting

Screws are provided. Refer to the System Set-Up on page 4. Perform the “Walk Test” (see page 3) prior to

mounting permanently.

The Sensor Transmitter’s IR Lens and infrared sensor must have an unobstructed view of the detection area that is

free of plants, shrubs and branches. Take care not to touch the Lens or allow the Lens to get damaged. Straighten

and extend the flexible antenna straight upward. Some objects may not be detected if the sensor is placed too high or

too low. Adjusting may be required prior to calling for technical support. Keep the sensor as close to the edge

of the driveway as possible. The sensor should be strategically located so that it detects objects moving across

detection zone. Do not mount the sensor facing the sun, bodies of water or any large reflective objects. This causes

variations in the temperature pattern "seen" by the sensor windows and may cause false alarms or damage the lens.

PLEASE NOTE: A shorter transmission range may occur when the outside temperature falls below 20 degrees F. due

to a natural drop in battery voltage. Lower sensitivity may occur during periods of heavy fog, rain or snow. This is due

to the moisture diffusing the infrared energy. The Sensor Transmitters are completely weatherproof and will operate to

-40 degrees Fahrenheit.

TRANSMITTER CODING ADJUSTMENT: The system coding is factory pre-set and should be adjusted only in the

event of interference from another source. Remove the battery cover to access the Five Position Coding DIP-Switch.

The DIP-Switch settings in the Sensor/Transmitter must match the settings in the Receiver. See diagram below.

SENSOR SENSITIVITY ADJUSTMENT: The Infra Red Sensor is located in the Transmitter Case behind the Infra

Red Lens. There is a two-position DIP-switch to adjust the Sensor’s Infra Red Sensitivity. This is factory pre-set and

should not be adjusted without consulting with Technical Support. In typical installations, changing these settings will

cause extremely erratic system behavior. See diagram below.
