Move the IRP2+ to avoid Electromagnetic
Interference
It is possible that the IRP2+ is receiving electro-
magnetic interference from a nearby television
or other appliance. Move the IRP2+ to another
location and reconnect the power supply.
Observe the IR Test LED.
• IR Test LED is ON or Flickering:
Go to Step 34

Test for Shorts
A) Verify that all connections at the IRP2+ are
correct. Look for a hair-like filament of wire
between the two contacts.
B) Verify that the sensor/keypad connections
are correct. Look for a hair-like filament of wire
between the two contacts.
C) Disconnect the sensor/keypad cable at both
ends and test the cable itself for shorts. Use an
ohm meter or electrical continuity checker. You
should read an open (Infinite Ohms) between
Red and Bare, Red and Black or Bare and Black.
After testing all connections and cable, observe
the IR test LED.
