Walk Test LED
1. LED lights for 3 minutes when motion sensed (only during walk test).
2. Wireless transmissions are sent for each detection (walk test can be used for receiver
test as well).
3. Motion stops (locks out) sensing for 20 seconds after LED flashes.
4. When complete, replace sensor base by snapping back onto unit.
NOTE:
The STI-34752 should be walk tested once per year.
Operation
1.
Motion stops (locks out) transmitting wireless sensor alarms for 3 minutes after
sending an alarm transmission.
This is to conserve battery life.
2. Walk Test LED does not activate in normal operating mode, only works during walk test.
3. Tamper: when cover is opened.
4. Supervisory: every hour.
Sensor Initialization
After a 30 second warm-up, the STI-34752 sensor is fully operational. During warm-up, the
LED flashes. After warm-up, the sensor starts a three minute walk test mode.
Alarm Processing
STI-34752 alarm processing is designed for extreme false alarm rejection. The processing is a
quantum leap above standard PIR motion sensors that simply count signal events. The fields
of view are set up so moving objects produce two detector signals of different frequencies,
while non-moving false alarm sources produce two detector signals of the same frequency.
Pet Immunity
STI-34752 is designed to allow the presence of pets (100 lbs/45 kg or lighter) without signaling
an alarm. It includes a special micro-element lens array that produces much stronger optical
signals for humans than for pets 100 lbs/45 kg or lighter. The optical sensitivity of each STI-
34752 is factory calibrated to ensure accurate discrimination between humans and pets.
NOTE
: Some pets (especially larger ones with very short hair), even if lighter than 100 lbs/45 kg,
may produce enough infrared radiation to cause alarms. STI-34752 users are strongly advised
to test the sensor with their own pets, in order to verify that the STI-34752 will not signal an
alarm when their pets are moving within its fields of view.
The diagram below shows the STI-34752 zones of greatest human/pet discrimination. The
STI-34752 should be mounted so pets will occupy only the lighter-colored spaces.

Programming Instructions
1. Remove base by releasing the snap closure located at the bottom center.
2. Put receiver in program mode (refer to receiver instructions for programming).
3. Remove battery cover and Mylar tab. Unit should immediately program in receiver. If not,
press the tamper switch. Snap battery cover back in place.
