STI 34409 - Manual (Page 3)

External Contacts: (Fig. 5)
• Alert Signal – Terminals must first have a
closed circuit then an open circuit any
time afterward will trigger an Alert signal.
• Restore Signal – Terminals have a
closed circuit.
When using the External Switch Terminals, remove the case knock out (Fig. 2) in the corner of the case
bottom to insert sensor wires. Connect to external contact block.
NOTE: If mounted outdoors, use silicone sealant on the wire and screw hole knock outs.
NOTE: In any configuration, an Alert or Restore signal must be triggered for any STI receiver to
acknowledge the device.

Sensor Supervision
The STI Universal Sensor has a supervision feature that monitors the battery condition, sensor
tampering and verifies that the sensor is within range of the STI Receiver. Sensor supervision can
be disabled for installations where the transmission signals may be locked when in the sensor’s
normal condition.
If the STI Universal Sensor has a Low Battery or triggered Tamper Switch, the sensor will send a
trouble signal to the receiver.
If the signal is out of range or there is a loss of communication, the receiver will indicate a trouble
condition between 12 and 24 hours from the time the signal was lost.
