Important Installation Notes

• Ensure wiring is done to the national wiring regulations in the country where the installation is
taking place.
• Ensure that a readily-accessible disconnect device is incorporated in the premises installation
wiring. Ensure it is provided externally to the equipment and as close as possible to the supply,
with a contact separation of at least 3.0 mm. Example: Fused Spur Unit.
• When fixing external wires, ensure that means are provided in the installation to prevent the
SELV (Safety Electrical Low Voltage) or signal circuits from coming into contact with live parts of
the power supply circuit. Wires shall be fixed near their terminal blocks.
• The end of stranded conductor shall not be consolidated by soft soldering at places where the
conductor is subjected to contact pressure. Example: Must not solder ends of wires which are to
be secured in detector and control panel terminal connectors.
• On completion of wiring use tie-wraps to prevent any loose wires causing a safety hazard
(material of cables tie shall be rated at least HB or better).
• Cable ties and hoses shall be separate for power supply cable and SELV (Safety Electrical Low
Voltage) wirings.
• Size of protective bonding conductors: minimum section 1.5mm². Example: Electrical Earth wire
connections.
