Product Description

The Ei3105TYCH is an Optical Smoke Alarm that runs
on a 9V 10 year lithium battery to provide a long lasting
life (supplied with the alarm).

The Ei3105TYCH is easily installed and comes supplied
with all necessary screw fixings.

The Ei3105TYCH particularly useful near kitchens as the
hush button will silence nuisance alarms from cooking
etc for 10 minutes.

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

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

check performance at least monthly

The “Hush/Test” button will silence nuisance alarms
The smoke detector will emit a beep every 40

seconds to indicate that the battery back up is
depleted and needs replacing

Model Ei3105TYCH 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 Ei3105TYCH 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..
