Appendix A: ZP wiring guide
118 ZP3 Fire Control Panel Installation, Commissioning, and Maintenance Manual
The ZP system uses an extremely flexible wiring arrangement. It is designed to
provide simple, low-cost wiring for new buildings. It can, in many cases, also use
existing wiring where a fire detection system is being upgraded. A key feature of
ZP the system is the ability to mix looped wiring and spurs on the same circuit. A
further advantage is that future extensions or changes to a system are easily
carried out, without in any way affecting the existing system or its wiring.
To make sure that systems function correctly, it is important that correct
wiring techniques are used. The wiring is an integral part of the complete system,
and use of unsuitable cable, or defective installation methods can cause the
system to malfunction.
This appendix provides specifications and guidelines for cable selection and
installation. Follow these practices to make sure that your ZP fire detection
system functions correctly and reliably at all times.
All wiring must be installed in compliance with local codes, and in accordance
with the requirements of the local authority having jurisdiction.
Where line powered output devices are used, adequate provision must be
allowed for in the system cabling to cater for the increased line current drawn.
In addition to the requirements specified in this appendix, all wiring should be
installed in compliance with Section 17 (paragraphs 17.1 - 17.15) and Section 24
(paragraphs 24.1 - 24.5) of British Standards BS 5839: Part 1: 1988.
Effective functioning of the system is dependant on the correct connection of the
panel power connections and must be wired as described under “Power supply”
on page 50 of this manual.
The panel must be connected to a source of power that is both clean
and reliable. The power source should not be shared by electrical equipment that
causes electrical noise or spikes. If the quality of the power feeding the panel is
suspect and electrical noise is present, assistance should be sought from Ziton
regarding earth and surge protection.
The panels, power supplies, and cables making up the fire detection system
should be connected to earth at one point only. This earth point must always be
at the panel. The only exception to this is when MICC cable is used. In this case
the cable shield may be connected at other points in the building.
