General Description

®
pro panel. It is not compatible with the 2-zone
TWINFLEX
®

®

Installation
The panel must be completely powered down before this card is fitted.
1. Remove the right hand cover moulding from the unit by unscrewing the two fixing screws.
2. Next disconnect the battery by removing one of the push on battery leads at the battery. Always disconnect
the battery first before removing the mains power to the panel.
NOTE: Do not disconnect the battery by removing the wires from the terminals on the CIE circuit
board. Doing this may allow the batteries to short circuit.
3. Remove mains power from the panel by removing the fuse in the fused spur that supplies the panel or
switching off the circuit breaker. At this stage there should be no LEDs lit on the panel and the display
should be blank.
4. Disconnect all cabling from the CIE terminals. Make sure these cables are suitably labelled to facilitate
correct re-connection after fitting the Expansion Card.
5. Unscrew the two fixing screws that secure the left hand CIE assembly, then slide the assembly to the left
and flip the assembly over clockwise.
