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.
Note: BS 5839-6 2004 gives the folowing recommendations
regarding the mains supply to be used in a Grade D system (The
Ei141/146 /161RC/166RC Smoke Alarms and Ei144/164RC
Heat Alarms can be used in a Grade D system). The power
supply for the Alarms should be derived from the public
electricity supply to the dwelling. The mains supply to the
Alarms should take the form of either:
(a) an independent circuit at the dwelling’s main distribution
board, in which case no other electrical equipment should be
connected to this circuit (other than a dedicated monitoring
device installed to indicate failure of the mains supply to the
Alarms); or
