On/Off: To turn Base Station off hold down the MuteButton until it powers down. The Base Station can beturned on by pressing the Mute Button.

Mute: Press and release the Mute Button to put theBase Station into Sleep Mode for one hour. After anhour it will activate automatically.

Battery: The AA batteries (not provided) in the PIRMotion Sensor will last up to 2 years depending onuse (Lithium batteries recommended for colderenvironments). If Base Station battery (optional) islow, it will beep every few minutes. Replace with 9-Volt battery (not provided). For peak performanceinspect batteries annually and replace as needed.

Programming PIR MotionSensor to Base Station

Test PIR Motion Sensor by waving hand in front ofsensor. Test light should flash. Secure cover with thesmallest screws.

Step 3

Insert battery pack facing away from circuit board andattach cover.NOTE: Ensure the batteries do not touch the circuitboard and the antenna and battery wires are notpinched.

Step 7

Mount PIR Motion Sensorhorizontally on solid surface a fewfeet off the ground and within 900' of Base Station (rotate sensor to accessscrew holes). Unit should be able to swivel asneeded. Attach sun/rain shield.NOTE: Keep PIR Motion Sensor antenna away frommetal objects. Do not mount PIR Motion Sensor indirect sunlight, near moving tree branches, or in thepath of a sprinkler system.

ACCESSORY

N/O (Normally Open)

COM (Common)

The Base Station has a relay which can activate otherdevices such as a doorbell, buzzer or light. The relayswitch can handle up to 120 AC volts at 10 amps.The accessory device will need a separate powersupply. The accessories can be purchased at any electronics store.

Advanced Features

TroubleshootingThe PIR Motion Sensor lights up, but the BaseStation does not respond.The PIR Motion Sensor must be programmed to BaseStation (See Step 6). Ensure Base Station is on and is not muted.If the green power light is not lit or is flashing, press the Mute Button on the top of the Base Station towake it up.If the green power is illuminated, look at the two smallwhite Base Station switches next to the Learn Button.The #1 Dip Switch should be down, towards thecircuit board. If it is up, the Base Station has beenmuted. If the Base Station signals when you press theLearn Button, it is not muted.

The Alert is not getting expected transmissionrange.Keep both antennas vertical and keep PIR MotionSensor antenna away from trees and metal objects.Ensure Base Station is in clearest possible sight ofthe PIR Motion Sensor. The less objects between thedevices, the longer the range.

PIR Motion Sensor is detecting motion only partof the time.To detect cars, it is best to mount PIR Motion Sensorat height of car’s motor and have it between ten andtwenty feet from the road. Swivel sensor as needed.

The Alert is giving false alarms.Check for moving tree branches or insects in sensorwindow. PIR sensor can also be triggered by lightshining directly in sensor window, such as reflectedsunlight, or motion in front of a light source.It is possible that condensation has built up on thesensor. Wipe condensation from PIR Motion Sensorwith cotton swab. Let it sit inside for a few hours,open to the air, without the batteries and it shouldcorrect itself.Check Sensor Switches on PIR Motion Sensor. SeeSwitch Settings.

Base Station beeps every ten minutes.The battery in the Base Station is low. Replace with 9-Volt battery or operate it using AC Adapter.

Base Station is not very loud.An accessory such as a bell, buzzer or light can beattached to the relay switch. The relay switch canhandle up to 120 AC volts at 10 amps. The accessorydevice will need a separate power supply.

NOTE: The manufacturer is not responsible for anyradio or TV interference caused by unauthorizedmodifications to this equipment. Changes ormodifications not expressly approved by themanufacturer could void the user’s authority tooperate the equipment.

Vehicle Alert Installation: For cars, the bestmounting position is about 4' high, between 10-20'back, and angled to see the back of car after passingthe sensor.
