Cable Terminations; Cable Quality And Installation - Honeywell NFS Supra Installation And Operating Manual

NFS Supra

4.1.1 Cable Terminations

This section provides guidance on where to bring cables into the enclosure
for ease of termination. Ensure the following requirements are met:
1. The mains supply should be brought into the control panel such that the
cable path to PSU is kept as short as possible.
2.
All loop and ancillary cable terminations should be brought into the panel
enclosure using cable entry points close to their termination points to ensure
.
tails are kept as short as possible
3. Some cable entry points, e.g. the nearest to mains entry, should be
left unused, where possible, to provide adequate mains supply input/
signal cable segregation.

4.1.2 Cable Quality and Installation

It is vitally important that good quality cable is used, and that correct installation techniques are
followed. In general, the following cable installation requirements must be met:
1. All cable sections must be circular to allow effective cable clamping
using the cable glands.
2. The cable must be screened (sheathed) to provide protection against
Radio Frequency Interference (RFI) and the screen must be connected
to earth at the control panel.
3. The screen must be continuous throughout the loop.
4. The system should be always connected to a safe earth with 0 V potential.
5. Cable recommended for use is MICC with a LSF PVC overcovering, a
fire resilient cable to BS7629 or PVC/SWA/PVC to BS6387.
