Mounting The Base Onto A Wall; Planning The Cable Layout In The Panel; Mains Wiring - C-TEC CAST XFP Engineering Manual

CAST XFP 32 ZONE ANALOGUE ADDRESSABLE FIRE ALARM PANEL

Mounting the base onto a wall

The panel can be surface, or semi-flush mounted onto a vertical wall, ≤2 m mounting height, using
the four mounting holes provided (note that an optional bezel, Part No. XFP735, is available for semi-
flush mounting).
To access the mounting holes, first remove the panel's lid and base PCBs, as detailed on page 6. The
mounting holes are suitable for use with No.8 roundhead or countersunk screws.
Always assess the condition and construction of the wall and use suitable screw fixings for the in-service
weight of the product. Any dust or swarf created during the fixing process must be kept out of base.

Planning the cable layout in the panel

All cables should be brought into the panel via the knockouts provided.
Note that the analogue loop and conventional sounder circuit cabling is
classed as extra low voltage and MUST be segregated away from mains
voltages. Careful planning is needed to ensure this.
Leave sufficient tails inside the panel to ensure straightforward connection of
the field wiring to the panel's terminals. Knockouts should be removed with
a sharp, light tap using a flat 6mm broad-bladed screwdriver, as shown in the
diagram (right).
Always ensure if a knockout is removed, the hole is filled with a good quality
strain relief cable gland. Any unused knockouts must be securely blanked off.

Mains wiring

All wiring should be installed in accordance with the current edition of the IEE Wiring Regs. (BS 7671), or
relevant national standards. The minimum requirement for the mains supply to the panel is fixed wiring
(no less than 1mm 2
system fed from an isolating switched fused spur at 3A, or a 6A Type B circuit breaker to IEC/EN60898-1.
The mains supply MUST be exclusive to the panel and be reliably earthed at the indicated earthing post.
As an alternative to a switched fused spur, a double-pole isolating switch (S), with 3mm air gaps on the
contacts & switching L & N only, may be used in the mains feed from the Main Distribution Board (A) to
the Panel (C), providing it meets the appropriate wiring regulations (see drawing below).
Hint! C-TEC's Fire Alarm Control
Panel Mains Keyswitch (Part No.
BF319) is a lockable, double-
pole keyswitch that provides
secure switching of mains supply
to a fire alarm panel (BF319 is
available @ www.c-tec.com).
