upon sensing smoke particles

• The smoke detector will automatically reset itself
and silence the sounder when smoke particles are
no longer present in the sensing chamber

• The smoke detector has a built in warning flag to
prevent installation of the detector without a battery
fitted

• The built in sounder will provide a minimum sound
output of 85dB at 3m

• The “Test/Hush” button will simulate smoke-use to

check performance at least monthly

Model Ei3105H Smoke Alarm

Installation & Placement

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 the Instruction Leaflet supplied with the Ei3105H for detailed
instructions as to how to correctly install and position the smoke detector

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.
(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..
