Warranty Information
Refer to the warranty information provided with the IntelliSense product for details.
WIRING: Observe polarity. Use 14-22 AWG wire. Push excess wire back into the wall. Reverse polarity will not damage the unit. Refer to wiring diagram (Figure 2) for connections.
MOUNTING LOCATION: Select location for both technologies, aim sensor towards interior, away from heat/cooling sources and moving machinery. Max range at 2.3m (7'6") height. Ensure clear line-of-sight. Use 1.2m (4ft) height for Pet-Alley lens.
MOUNTING PROCEDURE: Use screwdriver to push latch to separate housing. Lift PCB latch to remove PCB, gently pull by microwave antenna. Secure rear housing with keyholes or breakout tabs. Seal knockouts to prevent insect entry.
SYSTEM TESTING: Apply power. Minimize motion until self-test (1 min) completes. Walk-test after LEDs extinguish. Walk across protected area; 2-4 steps should light LEDs. No motion should have all LEDs off.
