WIRELESS MOTION ALERT SENSOR

Overview

The Wireless Alert Sensor is a Passive Infra-Red (PIR) Motion Sensor that detects movement of people and vehicles, while allowing small animals to pass through undetected. Each sensor has its own unique ID, for a secure radio link. The base station (not provided) can learn the signals of up to 8 sensors. The base station gives a single beep for the fi rst sensor that is programmed, a double beep for the second, and so on. Additionally, multiple base stations can work with the same sensor to sound in different places.

Assembly & Programming

1

Attach PIR Motion Sensor box to mounting plate with large silver screw. Tighten screw until PIR Motion Sensor stays in place when repositioned.

2

Install 4 AA Alkaline batteries. (Lithium batteries recommended for colder environments.)

LED light will fl ash.

Motion Sensor are in close proximity to each other.

Press and release Learn

Button on Base Station.

Buzzer will sound.

B Within 60 seconds, press the

Learn Button on the inside of the PIR Motion Sensor. LED light will illuminate and Base

Station will buzz.

PIR MOTION SENSOR INSTALLATION

Mount PIR Motion Sensor horizontally on solid surface

3-5 feet (1-1.5 m) off the ground and within 1/2 mile

(0.8 km) of Base Station (rotate sensor to access screw holes).

Unit should be able to swivel as needed.

Attach sun/rain shield.

NOTE: Keep PIR Motion

Sensor antenna away from metal objects. Do not mount

PIR Motion Sensor in direct sunlight, near moving tree branches, or in the path of a sprinkler system.

Vehicle Alert Installation: For cars, the best mounting position is about 4 feet (1.2 m) high, between 10-20 feet (3-6 m)back, and angled to see the back of car after passing the sensor.

10-20 feet (3-6 m)

4 feet (1.2 m)

Troubleshooting

The PIR Motion Sensor lights up, but the Base Station does not respond.

The PIR Motion Sensor must be programmed to Base Station

(See Step 3). Ensure Base Station is on and the volume is turned up.

Base Station beeps every 30 minutes.

The batteries in the Base Station or the PIR Motion Sensor(s) are low. Replace the 4 AA batteries. Check the PIR Motion

Sensor(s), if the LED illuminates on all of the PIR Motion

Sensors, change the batteries in the Base Station.

PIR Motion Sensor is detecting motion only part of the time.

Ensure the PIR Motion Sensor is set to the High Sensitivity setting (See Step 2). To detect cars, it is best to mount PIR

Motion Sensor at height of car’s motor and have it between

10-20 feet (3-6 m) from the road. Swivel sensor as needed.

The Alert is not getting expected transmission range.

Keep both antennas vertical and keep PIR Motion Sensor antenna away from trees and metal objects. Ensure Base Station is in clearest possible sight of the PIR Motion Sensor. The less objects between the devices, the longer the range.

The Alert is giving false alarms.

Check for moving tree branches or insects in sensor window.

PIR Motion Sensor can also be triggered by light shining directly in sensor window, such as refl ected sunlight, or motion in front of a light source.

It is possible that condensation has built up on the sensor. Wipe condensation from PIR Motion Sensor with cotton swab. Let it sit inside for a few hours, open to the air, without the batteries and it should correct itself.

Check Sensor Switches on PIR Motion Sensor. See Switch

Settings.
