Product Description

The Ei146 is an Optical Smoke Alarm that runs on 230V

AC mains power, and has a 9V alkaline battery back up

in the event of mains failure. The 9V battery will last for

up to 4 years in standby mode, and capable of powering

the smoke detector for up to 2 years in the event of

mains failure.

The Ei146 is supplied with the Easi-Fit base that allows

very quick and simple installation of the smoke alarm,

combined with simple detector head removal and

replacement. The Easi-Fit base automatically connects

both mains power and battery as the detector head

slides on to the Easi-Fit base.

The Ei146 has other advanced features such as high

performance optical chambers fitted with integral insect

screens to reduce the chances of false alarms, as well

as the ability to interconnect up to twelve alarms to allow

all alarms to sound if just one of the interconnected

alarms should be triggered.

The Ei146 has built in circuitry to aid suppression of

voltage transients and RF interference to further reduce

the chances of false alarms under such conditions.

Operation

The green indicator will illuminate to show mains

power is present

The red indicator will flash every 40 seconds to

show that the detector has performed an automatic

self test

The red indicator will flash rapidly to show an alarm

condition for the smoke detector

The “Test/Hush” button will either silence false

alarms or perform a unit self test

In “Test” mode the alarm will perform a self test and

sound the horn

In “Hush” mode the alarm enters a ten minute period

of reduced sensitivity to overcome false alarm

conditions, and will then automatically reset itself

When interconnected to other Ei mains powered

alarms, an alarm on one detector will trigger all other

interconnected alarms within one second (only the

triggered alarm will flash a red indicator)

The smoke detector will emit a beep and flash the

red light every 40 seconds to indicate that the

battery back up is depleted and needs replacing

Installation & Placement

Wiring for Interconnected Alarms

Be very careful about correctly wiring the alarms as mixing Live and Neutral

will blow/damage interconnected alarms.

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 instruction booklet for specific installation details

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. The

wiring can be installed when appropriate.

(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.. Connect wires to the unit

as in wiring diagram. All wiring must comply

with local codes.
