Ei SMOKE ALARMS - THE
FIRST CHOICE FOR LOCAL
AUTHORITIES AND
HOUSING ASSOCIATIONS
NATIONWIDE
Ei Professional smoke alarms and
ancillary products have been
specified by literally hundreds of Local
Authorities and Housing Associations
in England, Scotland, Wales and
Northern Ireland as the products of
choice for their retrofit programmes.
Many of these would be pleased to
discuss their experiences of product
reliability and after sales support with
interested parties. Please contact our
Customer Services Department for
further information.
In addition, many builders, architects
and installers recognise the benefits of
fitting smoke and heat alarms that
have proven to be extremely reliable
in many thousands of ‘New Build’
installations throughout the UK.
TECHNICAL SUPPORT
Our highly trained and experienced
staff in the Customer Services
Department will be pleased to assist
you with any queries that you may
have regarding installation,
maintenance, or product specification.

TROUBLE SHOOTING
Please Note: many alarms that are
returned to Aico as “faulty” are found
to have circuit damage. This is largely
due to incorrect wiring on installation.
Although all mains powered smoke
alarms are double insulated, mixing live
and neutral will damage
interconnected alarms. This damage
can also occur if the connector plug
momentarily short circuits across the
power pins when installation takes
place with the power on. It is essential
that live and neutral wires are correctly
identified and that all connections are
made before the mains power is
switched on!
Problem Solution
Alarm sounds
for no apparent
reason
Identify the alarm source. The red LED under the test button or on
the cover will flash rapidly only on the unit which is the source of
the alarm. Press hush button if fitted. Check for fumes, steam etc.
from the kitchen or bathroom (paint and other fumes can cause
nuisance alarms). Fan the alarm vigorously with a newspaper to
disperse fumes. If alarm does not stop, switch off mains and
remove the unit with the rapidly flashing red LED.
Alarm beeps
continuously
(approx once
per minute)
Alarm may be in ‘hush mode’ (Ei150, 151TL & 151TLR only). Cells (150
& 160 series) or batteries (140 series) may be depleted. Check the
green mains light is on. If not, check fuse, circuit breakers and wiring
connections. 140 series - the battery may require replacement.
Switch off the mains supply, remove the alarm and replace battery.
150 & 160 series - the cells may require recharging. This will occur
automatically if the mains power is connected. The cells are not
replaceable. If all the above actions have not silenced the beeping,
there may be a fault. Switch off the mains and replace the unit.
Interconnected
alarms do not
all sound
Hold test button for ten seconds to ensure that the signal is
transmitted to all alarms on the system. Switch off the mains power
and check that the live, neutral and interconnect wires are tight
and have been correctly connected on all alarms in the system.
Incorrect wiring will damage alarms.
Frequent
nuisance
alarms occur
Ensure the kitchen and bathroom doors are closed when in use.
Ensure that the alarm is sited at least 6m away from sources of
fumes. Contamination from insects, dust, paint etc. may have
occurred; clean the alarm. If the problem persists, resiting of the
alarm should be considered. Alternatively, changing to a model with
a different sensor type may resolve the problem.
All smoke alarms, but more particularly the
optical type, are prone to dust and insect
ingress which can cause false alarms. The
latest design, materials and manufacturing
techniques have been used in the construction
of our alarms to minimise the effects of
contamination. However, it is impossible to
completely eliminate the effect of dust and
insect contamination. Therefore, to prolong the
life of the smoke alarm it must be kept clean so
that excess dust does not build up. Any insects
or cobwebs in the vicinity of the smoke alarm
should be promptly removed. In certain
circumstances, even with regular cleaning,
contamination can build up in the smoke
sensing chamber causing the alarm to sound.
If this happens, the alarm must be returned for
servicing or replacement. Contamination is
beyond the manufacturer’s control, and is
considered normal wear and tear.
This list is not comprehensive. You should
refer to the specific user instructions that
accompany each product for further
guidance.
