Product Description
The Ei154TL 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 Ei154TL has 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 Ei154TL 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 Ei154TL 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
with smoke alarms.
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” button will perform a unit self test and
sound the horn
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 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.
