Product Description

The Ei164R is a Heat Alarm that runs on 230V AC mains
power, and has built in tamper proof rechargeable lithium
cells that act as a battery back up in the event of mains
failure. These rechargeable lithium cells are designed to
have a ten year life and outlast the life of the heat alarm
itself, whilst providing up to six months of heat alarm
operation without mains power.

The Ei164R is supplied with the Easi-Fit base that allows
very quick and simple installation of the heat 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 Ei164R allows the detector to be controlled remotely
by either a “Test/Hush” Switch (Ei152) or a Manual Call
Point (MCP400). If the Ei164R is also interconnected to
other Ei mains powered alarms then the whole system
will be controllable remotely.

The Ei164R has built in circuitry to aid suppression of
voltage transients and RF interference to further reduce
the chances of false alarms under such conditions.

Heat alarms are ideal for use in kitchens and garages,
where the use of optical or ionisation alarms would lead

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

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

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.
