ESD Precaution
Observe precautions for handling electrostatic sensitive devices. This particularly applies to
the precautions necessary to avoid Electro-Static Discharge.
This equipment is constructed with static sensitive components. Wear an anti-static earth
strap connected to panel enclosure
’s earth point. Before installing or removing any printed
circuit boards, or connecting cables, remove all sources of power (mains and battery).
Installing the System
General
Take care to avoid mounting the cabinet near 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. Cabling for the detection and sounder circuits 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.
Environment
The site chosen for the location of the panel should be clean, dry and not subject to shock or
vibration
.
Environments where there is damp, salt air, water ingress or extremes of
temperature must be avoided. The temperature should be in the range of -5°C to +40°C, and
the relative humidity should not exceed 95%.
Mounting the Cabinet
Before mounting the cabinet, remove the main PCB:
•
Remove power supply module wires from the PCB, taking note of where to
reconnect them.
•
Carefully pull main PCB from its mounting clips.
Secure the cabinet to the wall using the four indented holes in the back of the cabinet. Ensure
the cabinet is mounted level and in a convenient location for it to be operated and serviced.
Recommended screws size is M 4.0 * 38mm.
External cables should pass through a suitable gland and fitted to the cabinet via preformed
knockouts at the top and rear of the cabinet. Any unused knockouts must be securely
blanked off.
Remove any knockouts and ensure the cabinet is clear of swarf etc., prior to
refitting the PCB.
