SECTION 2 – INSTALLATION
General
• The installation of fire detection and alarm systems should be carried out in accordance with
current IEE wiring regulations and in line with B.S.5839 British Standard codes of practice for fire
alarm installations. The installation should be carried out by suitably qualified and experienced
technicians.
• Care should be taken with regards to avoiding the close proximity of high voltage cables or areas
likely to induce electrical interference. Earth links should be maintained on all system cables and
grounded in the control panel.
• Any junction boxes used should be clearly labelled FIRE ALARM.
• Any ancillary devices, e.g. door retaining magnets, must be powered from a separate power
source.
• Any coils or solenoids used in the system must be suppressed, to avoid damage to the control
equipment.
ESD PRECAUTION
Electronic components are vulnerable to damage by Electrostatic Discharges (ESD). An ESD wrist
strap, suitably grounded, should be worn at all times when handling pcbs. These wrist straps are
designed to prevent the build up of static charges, not only within a persons body, but on many other
materials. ESD damage is not always evident immediately, faults can manifest themselves at anytime in
the future.
All pcbs should be stored in static shielded bags (silvered) for safe keeping, when not mounted in the
control panel. Do not use “black” or “pink” bags and never
allow pcbs to come in contact with bubble
wrap or expanded polystyrene (packing chips).
Static shielded bags and disposable wrist straps are available from the manufacturer.
Warning, Control Panel Access Keys
The keys to the control panel must be kept, safely, by a responsible person. Hazardous voltages may
be present. Access to the inside of the panel is not normally required. Disconnect mains supply prior to
opening cabinet.
