Product Description
The Ei141 is an Ionisation 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 Ei141 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 Ei141 has other advanced features such 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 Ei141 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 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 every 40
seconds to indicate that the battery back up is
depleted and needs recharging

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.
