Product Description

The Ei156TLR is an Optical Smoke 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 smoke alarm itself, whilst providing up to six
months of smoke alarm operation without mains power.

The Ei156TLR allows the detector to be controlled

remotely by either a “Test/Hush” Switch (Ei152), a
“Locate” Switch (Ei159) or a Manual Call Point

(MCP400). If the Ei156TLR is also interconnected to
other Ei mains powered alarms then the whole system
will be controllable remotely.

The Ei156TLR has other advanced features such as
integral insect screens to reduce the chances of false
alarms, as well as the ability to interconnect up to twelve
alarms.

The Ei156TLR 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 recharging

The detector can be controlled remotely by either a

“Test/Hush” Switch (Ei152), a “Locate” Switch

(Ei159) or a Manual Call Point (MCP400).

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.
