Appendix A: ZP Wiring guide
Introduction
General
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.
Note:
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.
Panel power supply connections
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 46 of this manual.
CAUTION: The panel must be connected to a source of power, which is both clean and reliable. The
power source should not be shared by electrical equipment, which 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.
