Installation and Operation Manual
STI Wireless Driveway Monitor
TM
Part of the Wireless Alert Series
Thank you for purchasing the STI Wireless Driveway Monitor. Your satisfaction is very important to us.
Please take the time to read this manual carefully to get the most from your new product.
How the products works:
Because of its patented magnetometer sensor transmitter system, the Driveway Monitor will only be
triggered by cars or trucks - not people, animals and so forth. When a vehicle passes the Motion Alert®
Sensor Transmitter next to the driveway, the receiver unit inside the office or home sounds a chime
and flashes the alert light. The earth has a uniform magnetic field around it. A vehicle creates a slight
disturbance in the earth’s field. The sensor transmitter detects this disturbance and transmits a signal
to the receiver.
Before you start:
Refer to this drawing to become familiar with all the parts.

Install batteries into the sensor transmitter
1. Remove the sensor transmitter cap by turning it counterclockwise.
2. WITHOUT PULLING ON THE BRASS ANTENNA OR ANY WIRES, grasp the outside of
the battery/circuit board holder by the finger notches, twist gently and pull out. Insert
two “C” alkaline batteries (not included).
3. Replace the battery holder/sensor transmitter and sensor transmitter cap.
4. To test or program sensor transmitter, place the sensor transmitter on a table or
counter approximately 5-10 ft. away from the receiver.
Sensor transmitter can be
activated by rotating
and will make a faint clicking noise to verify operation.
5. Sensor should be programmed to receiver before mounting outdoors. Refer to
receiver instructions for programming. (Model STI-34150 is factory programmed for
your convenience.)
