Product Description
The Ei105C is anOptical Smoke Alarm that runs on a 9V
battery (supplied with the alarm).
It senses smoke using the light scatter
principle, giving a quick response to visible smouldering
fires
The Ei105C is easily installed and comes supplied with
all necessary screw fixings.
The Ei105C is fitted with a warning flag that pops up
when the battery is removed. This prevents the cover
from closing when there is no battery fitted to the unit.
When the battery is being installed or changed, this flag
must be held down while gently pushing the battery into
the battery holder
When the battery is first connected, the alarm may sound
for 2-3 seconds –this is normal and means that the
battery is connected correctly
Operation
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
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
The smoke detector has a built in warning flag to
prevent installation of the detector without a battery
fitted
The “Test” button will perform a self test and sound
the horn (it may take up to 10 seconds)
The smoke detector will emit a beep every 40
seconds to indicate that the battery back up is
depleted and needs replacing
9V BATTERY POWERED

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 Ei105C 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..
