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..
