INSTALLATION AND OPERATION INSTRUCTION
(Vehicle Detection System)
Install Batteries
1. Using a screwdriver (not included), remove the Battery Cover of the Sensor, and insert three
AAA batteries (not included). Replace the Battery Cover.
2. Using a screwdriver (not included), remove the Battery Cover of the Receiver, and insert
three C batteries (not included). Replace the Battery Cover.
Install Sensor and Receiver
1. Consider the following when choosing a location for the Sensor:
a. The passive infrared sensor detects heat. Avoid aiming it towards areas that produce
heat such as heater vents, windows where the sun hits, or outdoor spotlights.
b. Mount the Sensor at least three feet above the ground. If placed under the garage
eaves, be sure that the Sensor is not blocked by the roof fascia board.
c. If placed above eight feet high, the Sensor should be aimed downward so that it is
pointed toward the area being monitored.
2. Mount the Sensor to a flat surface with hardware (3).
3. Place the Receiver within 400 feet of the Sensor.
4. Mount the Receiver to a flat surface with hardware, or stand on a flat surface. The receiver
is not intended to be weather resistant.
Power Switch
The Power Switch has three settings:
a. Off: Power is off.
b. Hi: A loud beep will sound and the LED will flash when motion is detected.
c. Low: A short beep will sound and the LED will flash when motion is detected.
Operation
1.
To operate the Security Alert, slide the Power Switch on the Receiver to the “Hi” setting.
Allow 30 seconds for warm-up. Two short beeps will sound, indicating the unit is working.
2. Test the Sensor by walking or driving into the protected area. Another person should be
listening for the alarm to sound.
3. If the Sensor does not activate, Sensor relocation or aiming adjustment will be required.
4. If the Receiver does not activate with the sensor, reposition them closer together.
5.
Once you have determined that the unit is working properly, leave in the “Hi” setting or
adjust to the “Low” setting.
Low Battery
1. Replace the Sensor batteries when the LED on the Sensor turns on.
2. Replace the Receiver batteries when the LED on the Receiver turns on.
