• Do not locate in insect infested areas. Small insects
getting into the smoke detector chamber can cause
intermittent alarms. Insects and contamination on the
Heat Alarm sensor can increase its response time.
4. INSTALLATION
The Alarm is designed to be permanently mounted,
using it’s own built-in terminal block to connect it to the
mains. The mounting plate can be screwed directly to
the ceiling. Alternatively it can be screwed to a standard
junction box. It requires a current of 40mA. The Alarm
must not be exposed to dripping or splashing. There
are important markings on the underside of the alarm.
Caution
Alternative Energy Sources - (Wind, Solar, UPS etc.)
This product is designed to be connected to a Pure or
True Sine Wave 230 Vac supply.
If connecting to a power source that utilises an inverter,
e.g. PV solar panel, the Total Harmonic Distortion
(THD) must be less than 5%. If in doubt please check
with the manufacturer of the inverter.
This also applies to battery powered UPS (Uninterruptible
Power Supply) inverters.
Light Dimmer Circuits – The Alarms must not be
powered from a light dimmer circuit.
IMPORTANT PRECAUTION: Do not install the
Alarms in new or renovated buildings until all work
is completed (including floor coverings) and the
building has been fully cleaned. The wiring can
be installed when appropriate. (Excessive dust
and debris from building work can contaminate
the smoke chamber or heat sensor and cause
problems, it will also invalidate the guarantee).
If it must be installed, first cover it completely,
particularly around the edges, with a dust cover (eg.
with the elasticated cover supplied or a plastic bag),
until all cleaning is finished.
The Alarm must not be connected when the house
wiring insulation is being checked with high voltages.
i.e. Do not use a high voltage insulation tester on the
alarm.
WARNING: Mains operated Alarms should be
installed and interconnected by a qualified electrician
in accordance with the Regulations for Electrical
Installations published by the Institution of Electrical
Engineers (BS7671). Failure to install this Alarm
correctly may expose the user to shock or fire hazards.
WARNING: The Alarm must be continuously powered
24 hours a day so it is important that it is not on a circuit
that can be turned off by a switch.
