1. Do not mix old and new batteries.
Do not mix alkaline, standard
(carbon-zinc), or rechargeable
(nickel-cadmium) batteries. Position
batteries in proper polarity. Do not
use swollen or leaking batteries.
2. Keep installation area clean.
Cluttered areas invite accidents.
3. Observe installation area
conditions. Keep work area
well lit during installation.
4. Check for damaged parts. Before
using any product, any part that appears
damaged should be carefully checked
to determine that it will operate properly
and perform its intended function.
Check for any broken or damaged
parts and any other conditions that may
affect its operation. Replace or repair
damaged or worn parts immediately. Do
not use the Alert System if any switch
does not turn on and off properly.
5. Replacement parts and accessories.
When servicing, use only identical
replacement parts. Use of any
other parts will void the warranty.
6. Keep children away. Mount the Sensor

Setup Instructions
Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the
beginning of this document including all text under subheadings therein
before set up or use of this product.
Installing Batteries
CAUTION! Do not mix old and new
batteries. Do not mix alkaline,
standard (carbon-zinc), or rechargeable
(nickel-cadmium) batteries. Position
batteries in proper polarity. Do not
use swollen or leaking batteries.
1. Using a screwdriver (not included),
remove the Battery Cover of the
Sensor, and insert a 9V battery (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.
Note: An optional 6 volt, 200 mA power
adapter (not included) can be used to
power the Receiver instead of batteries.
Installing the Sensor and Receiver
CAUTION! Verify that installation
surface has no hidden utility lines
before drilling or driving screws.
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 3
feet above the ground. If placed
under the garage eaves, be sure
that the Sensor is not blocked
by the roof facia board.
c. If placed above 8 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.
Note: Obstructions may reduce
the receiving range.
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.
Note: Do not install the Receiver
in a location that will get wet or
directly exposed to the elements.

Operation
Power Switch
The Power Switch has three settings:
a. Off: Power is off.
b. Hi: A loud beep will sound
(approximately 92dB) and the LED
will flash when motion is detected.
c. Low: A short beep will sound
(approximately 80dB) and the LED
will flash when motion is detected.
Operation
1. To operate the Driveway 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.
