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..
