Product Description

The Ei144 is a Heat 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
heat detector for up to 2 years in the event of mains
failure.

The Ei144 is supplied with the Easi-Fit base that allows
very quick and simple installation of the heat alarm. The
Easi-Fit base automatically connects both mains power
and battery as the detector head slides on to the Easi-Fit
base.

The Ei144 has 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 Ei144 has built in circuitry to aid suppression of
voltage transients and RF interference to further reduce
the chances of false alarms under such conditions.

The Ei144 heat alarm gives a fire warning when the
temperature at the unit reaches 580C. Heat alarms are
ideal for use in kitchens and garages, where the use of
optical or ionisation alarms would lead to unwanted
nuisance alarms.

On escape routes this alarm must be interconnected

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 heat 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 heat detector will emit a beep 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.

Locate heat alarms in rooms adjoining or on escape routes – kitchens,
garages, boiler houses etc. where smoke alarms are unsuitable. Install within

5.3m of potential sources of fire.
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.
