 Possible bad device causing communication errors
- Disconnect devices at half way points until the fault clears to locate
the faulty device
1.1.2.7 Extra Device

A device is located on the addressable loop that is addressed at a location that is not
programmed.
Possible causes:
The panel has identified a device/card at an address that is not in the panel programming.

A card/device may be incorrectly addressed bringing up an Extra Device fault, but the
programmed device’s address will display “Points defined but not inserted.”
