• Disconnect the 10-way PSU loom, the lid/base connector
cable and all remaining connections from the top of the
Main Control PCB.
• Unfasten the retaining screw at the bottom left of the
Main Control PCB and slide the PCB up and over its
mounting pillars.
• Insert the two hexagon spacers (supplied with the
network driver card) through the holes on the Main
Control PCB and secure them using the nuts and washers
(supplied), see right.
• Take the network driver card and line its holes up with
the two hexagon spacers, ensuring that it’s 6-way pin
connectors are correctly inserted the Main Control PCB.
• Secure the card onto the hexagon spacers using the two
6mm slotted screws (supplied).
• Refit the Main Control PCB and all relevant connection
cables previously removed. Ensure that the PCB retaining
screw is firmly fastened down.

Network/repeater wiring (optional)
CAST XFP’s network protocol allows connection of up to eight CAST XFP main panels (any variant) over a
2-wire RS485 non-redundant network. Alternatively, the network can connect up to eight XFP repeaters
to one non-networked CAST XFP main panel. FOR NETWORK WIRING 2-CORE SCREENED, ENHANCED
FIRE-RESISTANT CABLE IS RECOMMENDED.
It is NOT possible to mix CAST XFP main panels and XFP repeaters on the same network.
Key features of the non-redundant network protocol when used for connecting CAST XFP main panels:
• Allows the connection of up to eight CAST XFP main panels (any mix of 1 loop 16 zone CAST XFPs
and 2 loop 32 zone CAST XFPs)
• Up to 1km of cable may be fitted to a CAST XFP main panel network.
• Each networked CAST XFP main panel can be programmed to:
Accept Fires from other main panels.
Accept Faults from other main panels.
Accept Control actions from other main panels, e.g. Silence Alarm Sounders and Control Panel Reset.
Accept Disablement commands from other main panels for zones, sounders and output sets.
(Each of these four functions may be individually selected via the panel’s PC programming tools.)
• All panels monitor all other panels for network wiring faults.
• Fires on remote panels are displayed on local panels including the point description of the alarm’s origin.
• Faults on remote panels are displayed on local panels.
• Cause and effects can be programmed into local panels dependent on which remote panel is in alarm.
• The network supports the programming of site information into remote panels from a PC
connected at a local panel.
• Time and date is common to all panels throughout the network.
Key features of the non-redundant network protocol when used for connecting XFP repeaters
• Allows the connection of up to eight XFP repeaters (any mix of 1 loop 16 zone repeaters and
2 loop 32 zone repeaters) to any non-networked main panel.
• Up to 500m of cable may be fitted to an XFP repeater network.
• Each XFP repeater offers all the functions and controls of a CAST XFP main panel.
Any CAST XFP main panel connected to the non-redundant network requires the installation of a
network driver card (Part No. AFP711), as shown in Fig.11 below. Repeaters come with a network
driver card already
fitted. Typical network wiring details are shown in Fig.12, page 14.

AND DISCONNECT THE PANEL’S BATTERY BACK-UP SUPPLY.
