Installation & Placement
Wiring for Interconnected Alarms
Be very careful about correctly wiring the alarms as mixing Live and Neutral
will blow/damage interconnected alarms.
Alarms should be placed in accordance with the general guidelines shown in
the diagram above. These recommendations are based on the problem of
areas of “dead air” close to corners of rooms and apexes of ceilings, which
could result in the prevention of smoke reaching the smoke detector
Please consult instruction booklet for specific installation details
Important Precaution:
Do not install the actual smoke/heat alarm
itself 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 and
cause problems, and it will also invalidate the
guarantee). If it must be installed, cover it
completely, particularly around the edges, with
a dust cover (eg. a plastic bag), until all
cleaning is finished.. Connect wires to the unit
as in wiring diagram. All wiring must comply
with local codes.
