3.2 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 wit
hin a person’s body,
but on many other materials.
ESD damage is not always evident immediately; faults can manifest themselves at any time in the future.
All pcbs should be stored in static shielded bags (silvered) for safe keeping, when not mounted in the control
panel.
3.3 GENERAL
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. The detection and sounder circuit cabling is classed as extra low voltage and must be segregated away
from mains voltage.
• 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.
3.4 MOUNTING THE CABINET
The site chosen for the location of the panel should be clean, dry and not subject to shock or vibration. Damp,
salt air or environments where water ingress or extremes of temperature may affect the panel must be avoided.
The temperature should be in the range -5° to +40°C, and the relative humidity should not exceed 95%.
Before mounting the cabinet remove the main PCB.
Remove the power supply module connecting wires from the main PCB, taking care to note where to re-connect
them. The main PCB can then be carefully pulled off it’s mounting clips.
Secure the cabinet to the wall using the four indented holes in the back box. Ensure the box is mounted level
and in a convenient location where it may be easily operated and serviced.
External cables should be glanded via preformed knockouts at the top and rear of the cabinet. Remove any
knockouts and ensure the cabinet is clear of swarf etc prior to refitting the PCB. Always ensure that if a
knockout is removed, the hole is filled with a good quality cable gland. Any unused knockouts must be securely
blanked off.
Knockouts should be removed with a sharp tap at the rim of the
knockout using a flat 6mm broad bladed screwdriver.
Use of excessive force will damage the enclosure around the knockout.
