Optical Feedback Loop
If there is an IR sensor and an IR flasher located
within the same room an "optical IR feedback
loop" can occur. Replace the IRC-1 Flooding
Flasher with an IRC-2 MicroFlasher on the front
panel sensor window of each component.
Place the enclosed IR blocking cover over each
of the IRC-2 flashers. Retest the system.
• Good Operation:
Congratulations!
• Poor Operation:
Go to Step 16 (adjust Flasher
Level and Position) Retest system.
•
Still Poor Operation:
Go to Step 21
•
21
Replace IRP2+ and Flasher(s)
Reconnect the system with a new IRP2+ and
new flasher(s).
• Poor Operation Continues:
Go to Step 22

Interference that Does Not Light the IR
Test LED
Some very rare examples of interference (both
optical and electro-magnetic) do not light up
the IR test LED but do prevent proper opera-
tion. Go to steps 36 and 37. Examine your
installation carefully for a source of low-level
optical or electromagnetic interference.

Disconnect All Sensors and Keypads and
Test One Sensor Input
Disconnect all Sensors and Keypads.
Reconnect one of the sensor cables and retest
the system (Have someone watch the green IR
LED on the IRP2+ while you aim a remote con-
trol at a remote sensor and press a button).
• IR Test LED Flashes:
Go to Step 24
• IR Test LED Off:
Go to Step 25
•

Test Second Sensor Input
A) If you DO NOT have a second sensor/
Keypad, Go to Step 25.
B) If you DO have another sensor/keypad,
connect it to the second sensor input. Retest
the system (Have someone watch the green IR
LED on the IRP2+ while you aim a remote con-
trol at a remote sensor and press a button).
• IR Test LED Flashes:
Go to Step 12
• IR Test LED Off:
Go to Step 25

Bad Connections at the IRP2+ and/or at
the Sensor/Keypad.
Verify that all connections are good both at
the IRP2+ Sensor Inputs and at the remote
sensor/keypad. Check that the jacket of each
conductor has been properly stripped and
