Network/Repeater Wiring (Optional) - C-TEC CAST XFP Engineering Manual

CAST XFP 16 ZONE ANALOGUE ADDRESSABLE FIRE ALARM PANEL

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 1/2 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
1/2 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 XFP main panel connected to the non-redundant network requires the installation of a
CAST
network driver card (Part No. XFP761), 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 13.
Fig.11 : Installing the Network Driver Card
CAUTION: BEFORE INSTALLING THE NETWORK DRIVER CARD, ISOLATE THE MAINS SUPPLY
AND DISCONNECT THE PANEL'S BATTERY BACK-UP SUPPLY.
With reference to the diagram (right):
• Secure the network driver card inside the panel
using the two retaining screws provided.
• Connect the two-way power supply loom
(supplied with the card) between PL1 on the
card and PL2 on the Power Supply PCB.
• Connect the 8-way telecoms-style connector
cable (supplied with the card) between PL2 on
the card and socket SK2 on the rear of the Main
Control PCB.
Note: DIP switch (SW1) on the network driver card has no function when used with this panel.
However, all networked CAST XFP main panels require a unique ID number (1 to 8) assigning.
To assign this number and set up network comms, see NETWORK FUNCTIONS page 21 for details.
XFP repeaters DO NOT require an ID number.
