STI Universal Sensor
Model: STI-34401
Thank you for purchasing the STI Universal Sensor. 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 Product Works
The STI Universal Sensor is a wireless transmitter that can be configured to initiate a transmission to any
STI Receiver three different ways: internal magnetic sensor, internal tilt sensor or external switch.
Plan Your Installation
Universal Sensor Setup
1. Open sensor case using a flat head screwdriver in side case slot.
2. Configure the jumpers for the desired application (see Jumper Configurations Fig. 1).
3. Activate battery by removing the red tape.
4. Program the STI Universal Sensor into the STI receiver. Refer to the STI receiver installation
5. Snap base into lid. Tamper switch spring automatically seats within the locator ring on the lid. Tamper
6. Test the sensor for proper operation before permanently mounting.
7. Select mounting option.
1) Refer to the Operation section on the following pages to determine which sensor configuration is
best for your application.
2) Refer to the Sensor Supervision section to understand the use of this feature. It is recommended
to leave the sensor in the supervised state (J3 uncut) until false trouble signals are displayed on the
receiver. If you need to disable sensor supervision, the sensor must be deleted from the receiver
and reprogrammed into the receiver. Refer to your receiver’s installation instructions.

alert is triggered when the spring releases identifying when case is opened/broken/ajar.
OPTION 1: Mount with double sided foam tape provided to the back of the case (Fig. 2).
OPTION 2: Remove the circuit board from the case bottom. Drill 1/8 inch holes through the case
and use the screws (provided). For added protection, cover metal screw heads on the inside of
the case bottom with electrical tape (Fig. 2) to isolate the circuit board. Replace the circuit board
in the case bottom.

Magnetic Sensor: (Fig. 3)
• Alert Signal – Magnet is over approximately 1 1/3 inches from the device.
• Restore Signal – Magnet is brought within approximately 1 inch from the device.
When using the Magnetic Sensor, the bottom case may be inserted into the top case in reverse
depending on which direction the Magnetic Sensor should face.

Tilt Sensor: (Fig. 4)
• Alert Signal – Sensor is tilted more than 45° from vertical.
• Restore Signal – Sensor is tilted less than 45° from vertical.
When using the Tilt Sensor, the arrow on the bottom should point straight up in the non-triggered state.
NOTE: Metal mailbox may reduce transmission range.
