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

CAST XFP 16 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,
five mounting holes provided (see Fig.2 below). To access the mounting holes, first remove the panel's
lid and base PCBs, as detailed on page 5. The mounting holes are suitable for use with No.8-10 or 4-5mm
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 the base. Note that the central mounting hole can be used to temporarily hang the back
box so it can be levelled and its remaining fixing points marked for drilling.

Do not drill any additional holes
for cable entry in this shaded area.
This is where the PCBs and
backup batteries will be located.

Planning the cable layout in the panel

All cables should be brought into the panel via the drill outs 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. We
recommend tails of at least 20-30cm are left inside the panel to ensure straightforward connection of
the field wiring to the panel's terminals.
Drill centre points are provided in the panel base to aid drilling tools. Cut out suitable holes in the panel
using a hole saw directed by a pilot bit in the centre of the hole saw. Always ensure if a hole is cut out
it is filled with a good quality strain relief cable gland. Any unused holes 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).
