Product Description
The Ei105R is an Optical Smoke Alarm that that is
designed to operate with suitable 12 volt control panels
and to provide a loud local alarm.
Optical smoke alarms use the light scatter principle to
detect smoke particles entering the optical chamber
within the alarm.
Optical sensing technology gives a rapid response to
visible smouldering fires.
The Ei105R is easily installed and comes supplied with
all necessary screw fixings.
Relay contacts (normally open and closed supplied) are
available for triggering the panel itself and its associated
ancillary products, such as extra loud sirens, magnetic
door holders, etc.
The alarms can be interconnected so that when one
alarm senses fire, all the units located throughout the
premises sound.
Operation
The smoke detector will activate the built in sounder
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 built in sounder will provide a minimum sound
output of 85dB at 3m
In “Test” button will perform a self test and sound
the horn (it may take up to 10 seconds)
Interconnect up to 12 other alarms (9V ionisation,
optical or heat) when one senses smoke, all alarm.
Helps ensure warning will be heard throughout the
house

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 Ei105R 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..
