4. CHANGING THE BATTERY
(Models Ei141 / 144 / 146 only)
1. Switch off mains power to alarm (green light on cover
should go out).
2. Remove unit as shown in “ALARM REMOVAL” section on
page 2.
3. Locate battery slot in base of alarm as shown below.
4. Unclip battery from battery snap connectors.
5. Connect new battery by clipping back on to battery snap
connectors.
Use
only
9V
Alkaline
batteries
Duracell MN1604, Energizer 522. Other batteries can
cause problems.
We recommend that the “use by date” on the battery should
still have at least 2 years to go. Older batteries will give
beeps prematurely.
6. Slide unit back on to the base. A click should be heard as
the alarm engages. (The unit cannot be replaced on the
base unless a battery is installed).
7. Press and hold the test button - horn should sound loudly.
8. Reinstate mains power to alarm (green light on cover
should come on).
We recommend that the battery is replaced at least every
three years for optimum performance.
5. TESTING & MAINTAINING YOUR ALARM
INSPECTION &TESTING PROCEDURE
Check all your alarms weekly, especially after initial
installation or after re-occupation (e.g. following a holiday):
(i) Check that the green mains indicator light is on. (If it is
off check circuit breakers, fuses and wiring etc.) Check the red
light on the cover flashes every 40 seconds.
(ii) Press the test button for up to 10 seconds to ensure the
sensor chamber, electronics and sounder are working. A red
light on the cover, will flash while horn is sounding. The alarm
4
B16009-R0-160RC SERIES-U&C
17/1/07
11:13 AM
Page 4
will stop when the button is released. Pressing the test button
simulates the effect of smoke or heat during a real fire and is
the best way to ensure the Alarm is operating correctly.
WARNING: DO NOT TEST WITH FLAME
This can set fire to the Alarm and damage the house
We do not recommend testing with smoke or heat as the
results can be misleading unless special apparatus is used.
(iii) Check for any sign of contamination such as cobwebs or
dust and clean the alarm as described in the “CLEANING
YOUR ALARM” section on page 6, if necessary.
(iv) Interconnected Alarms only - Test the first unit by
pressing the button for 10 seconds. All the units should alarm
within 10 seconds of the first horn sounding. The red light on
the first unit only will flash about once a second. Check all the
other units similarly.
(v) Check the functioning of the mains battery back-up directly
after installation and then at least yearly as follows:
- Turn off the mains power at the distribution board and check
that the green indicator light is extinguished.
- Press the test button and ensure the horn sounds loudly for
10 seconds.
Turn on the mains supply at the distribution board only if the
unit passes the above test.
Note: If the mains is disconnected and the battery is almost
depleted the unit will beep every 40 seconds for at least 30 days.
(vi) Monitor the alarm over a short period of time for any
beeps.
5.1 If the unit is beeping
The Alarm automatically monitors the battery every 40
seconds to ensure that it is satisfactory. If it is depleted it will
give a short beep every 40 seconds.
Models Ei141, Ei144 & Ei146 only
Before replacing the battery, check that the beeps are not
due to one of the following:
(i) battery snaps not connected properly.
(ii) On the Optical Smoke Alarm only (Ei146) if the unit
beeps and the red light does not flash at the same time it
indicates a problem with the smoke chamber - see
“CLEANING YOUR ALARM” section on page 6.
(iii) If the beeps have continued for over 20 minutes (and
the other causes of beeps have been ruled out - see
“TROUBLESHOOTING” section on page 11) the battery
must be replaced.
See “CHANGING THE BATTERY” section on page 4.

Models Ei161RC, Ei164RC & Ei166RC only
(i) Check that the green mains power light is on. If it is off
the Alarm is not receiving mains power and is being
powered from its internal back-up cells. The beeps
indicate that they are depleted. The cells are not
replaceable. Re-connect the mains, check fuse, circuit
breakers and wiring. If in doubt contact a qualified
electrician.The beeps should cease within 2 hours as the
cells charge up. Fully charged, the cells will provide up to
6 months back-up without mains power.
(ii) On the Optical Smoke Alarm only (Ei166RC) if the
unit beeps and the red light does not flash at the same
time it indicates a problem with the smoke chamber - see
“CLEANING YOUR ALARM” section on page 6.
If all of the above possible causes of beeps have been
ruled out, but the beeping has still persisted for over 2
hours with the green light on - the rechargeable cells
may be defective. The Smoke / Heat Alarm must be
returned to the manufacturer for repair or replacement - see
“GETTINGYOUR ALARM SERVICED” section on page 10.
Please note: The ionisation alarms (Ei141/161RC) give two
short beeps about a second apart at the end of the hush
period (i.e. about 10 minutes after test/hush button has been
pressed). These two beeps should not be confused with low
battery beeps.
A unit will operate from the mains alone, even with a fully
depleted or a defective battery (and give beeps every minute),
though it may not give sufficient warning of fire if the mains
supply is disconnected for any reason. If there are any
problems get a qualified electrician to inspect the house
wiring and connections to the alarms.
If there are still problems the unit must be returned for
examination - see “GETTING YOUR ALARM SERVICED”
section on page 10.
6. CLEANING YOUR ALARM
WARNING: Electrical shock hazard. Disconnect the AC mains
at the fuse box or circuit breaker powering the Alarm before
following the cleaning instructions.
Clean your Alarm regularly, particularly in dusty areas. Use
the narrow nozzle attachment of your vacuum cleaner to
remove dust, insects and cobwebs from the sides and cover
slots where the smoke or heat enters.To clean the cover, wipe
with a damp cloth. Dry cover thoroughly with a lint free cloth.
WARNING: Do not paint your Alarm.
Other than the cleaning described above, no other customer servicing of
this product is required. Repairs, when needed, must be performed by the
manufacturer.
All Alarms are prone to dust and insect ingress which can cause false
alarms or failure to alarm.

The latest design, materials and manufacturing techniques have been used
in the construction of our Alarms to minimize the effects of contamination.
However it is impossible to completely eliminate the effect of dust and
insect contamination, and therefore, to prolong the life of the Alarm you
must ensure that it is kept clean so that excess dust does not build up. Any
insects or cobwebs in the vicinity of the 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 or fail.
If this happens the alarm must be returned to us for servicing or
replacement. Contamination is beyond our control, it is totally unpredictable
and is considered normal wear and tear.
For this reason, contamination is not covered by the guarantee and a
charge is made for servicing such units.
If you experience persistent false alarms, in particular locations, due to
contamination of the smoke chamber you could consider replacing Optical
Smoke Alarms (Ei146/166RC) with Ionisation Smoke Alarms
(Ei141/161RC). Ionisation type alarms are less susceptible to dust than
Optical type alarms.
7. NUISANCE ALARMS
When sure that it is just a nuisance alarm, simply press the
test/hush button briefly on the Alarm to silence the unit for 10
minutes.
If, when the alarm goes off, there is no sign of smoke, heat or
noise to indicate that there is a fire, you should get your family
into a safe place, before you start investigating.
Check the house carefully in case there is a small fire
smouldering somewhere.
Check whether there is some source of smoke or fumes, for
example cooking fumes being drawn past the Smoke Alarm
by an extractor.
If there are frequent nuisance/false alarms it may be
necessary to re-locate the device away from the source of the
fumes or replace an Ionisation Alarm with an Optical Alarm. If
for some reason the alarm continues to sound without smoke
or heat being present (due to insect infestation or
contamination build-up for example) the units can be silenced
by disconnecting the mains power and removing the unit - see
“ALARM REMOVAL” section on page 2.
If cleaning the Alarm does not correct the problem it can be
returned to the manufacturer for repair or replacement - see
“GETTINGYOUR ALARM SERVICED” section on page 10.
Hush Feature
All the Smoke/Heat Alarms have a combined Test/Hush
Button to help you control nuisance false alarms.
1. To cancel a false alarm, press the Test/Hush Button located
on the cover. The Alarm will automatically switch to a reduced
sensitivity condition (very large levels of smoke from a nearby
fire will override the Hush on the Smoke Alarms). This
condition allows unwanted alarms to be silenced for a period
of approximately 10 minutes.
The unit will flash the red light every 10 seconds (instead
of the normal 40 seconds) to indicate the sensitivity is
7
B16009-R0-160RC SERIES-U&C
17/1/07
11:13 AM
Page 7
reduced. At the end of the hush period the Ionisation
Smoke Alarms (Ei141/161RC) and the Heat Alarms
(Ei144/164RC) will give two short beeps.
On interconnected Alarms, pressing the Test/Hush Button on
the one sensing smoke (i.e. the one with the red light flashing
every second) will silence all alarms. Pressing the Hush
Button on any other Alarm will not cancel the alarm.
2. The unit will reset to normal sensitivity at the end of the
silenced period. If additional silenced time is required, simply
push the Test/Hush Button again.
8. IMPORTANT SAFEGUARDS
When using household protective devices, basic safety
precautions should always be followed, including those listed
below:
• Please read all instructions.
• Rehearse emergency escape plans so everyone at home knows
what to do in case the alarm sounds. Further information can be
obtained from the Home Office Publication or from your local fire
prevention officer.
• To maintain sensitivity to smoke, do not paint or cover the
Smoke Alarm in any manner; do not permit any
accumulation of cobwebs, dust or grease.
• If unit has been damaged in any way or does not function
properly, do not attempt a repair. Return the Alarm - see
“GETTINGYOUR ALARM SERVICED” section on page 10.
• This appliance is only intended for premises having a
residential type environment.
• Smoke / Heat Alarms are not a substitute for insurance. The
supplier or manufacturer is not your insurer.
• The chamber inside the Ionisation (Ei141/161RC) Smoke
Alarms contains a small amount of radioactive material
(33kBq of Amercium 241). Do not tamper with the chamber.
You may safely install and clean the Smoke Alarm following
this leaflet’s instructions.
• Do not dispose of your Alarm in a fire.
9. PLANNING YOUR ESCAPE ROUTE
Use the Smoke / Heat Alarm Test Buttons to familiarise your
family with the Alarm sound and to practice fire drills regularly
with all family members. Draw up a floor plan that will show
each member at least 2 escape routes from each room in the
house.
Children tend to hide when they don’t know what to do. Teach
children how to escape, open windows, and use roll up fire
ladders and stools without adult help. Make sure they know
what to do if the alarm goes off - see overleaf.
8
B16009-R0-160RC SERIES-U&C
17/1/07
11:13 AM
Page 8
1. Check room doors for heat or smoke.
Do not open a hot door. Use an
alternate escape route. Close doors
behind you as you leave.
2. If smoke is heavy, crawl out, staying
close to floor. Take short breaths, if
possible, through a wet cloth or hold
your breath. More people die from
smoke inhalation than from flames.
3. Get out as fast as you can. Do not
stop for packing. Have a prearranged
meeting place outside for all family
members. Check everybody is there.
4. Call the Fire Brigade from a
neighbour’s house. Remember to give
your name and address.
5. NEVER re-enter a burning house.
Limitations of Smoke / Heat Alarms
Smoke / Heat Alarms have significantly helped to reduce the
number of fire fatalities in countries where they are widely
installed.
However independent authorities have stated that they may
be ineffective in some circumstances. There are a number of
reasons for this:
• The Alarms will not work if the mains power is off and the battery
is depleted. On the Ei141/144/146 alarms the batteries should be
replaced every three years as a precaution or if the unit gives a
low battery beep.
• NOTE: Constant exposure to high or low temperatures or
high humidity may reduce the life of the Alkaline battery.
• Smoke / Heat Alarms will not detect fire if sufficient smoke /
heat does not reach the alarm. Smoke / heat may be
prevented from reaching the Alarm if the fire is too far away,
for example, if the fire is on another floor, behind a closed
door, in a chimney, in a wall cavity, or if the prevailing air
draughts carry the smoke / heat away. Installing Smoke /
Heat Alarms on both sides of closed doors and installing
more than one Smoke / Heat Alarm as recommended in the
‘INSTALLER INSTRUCTIONS’ booklet significantly
improves the probability of early detection.
• The Alarm may not be heard.
• A Smoke / Heat Alarm may not wake a person who has
taken drugs or alcohol.
9
B16009-R0-160RC SERIES-U&C
17/1/07
11:13 AM
Page 9
• Smoke / Heat Alarms may not detect every type of fire to
give sufficient early warning.
• Fire Authorities recommend that both Optical and Ionisation
Smoke Alarms should be fitted for the fastest response to all
types of fires.
• Smoke / Heat Alarms don’t last indefinitely. For example if
there is a build up of contamination, performance will be
impaired.
It is recommended that the Smoke / Heat Alarms are replaced
after 10 years as a precaution.
10. ALARM CONTROL (OPTIONAL)
Models Ei161RC / 164RC / 166RC only
A System Control Switch (Ei1529RC) is available as an optional
accessory. It allows the user to perform the following functions
from a remote location:
LOCATE - If alarms sound press Locate to allow the source
of alarm to be identified.
HUSH - Press Hush to silence nuisance alarms.
TEST - Operate weekly to Test the alarms.
MAINS CHECK - Test will not work with mains absent.
11. GETTING YOUR ALARM SERVICED
If your Alarm fails to work after you have carefully read all the
instructions, checked the unit has been installed correctly, and
is receiving AC power (green light on) contact Customer
Assistance at the address given at the end of this leaflet. If it
needs to be returned for repair or replacement put it in a
padded box and send it to “Customer Assistance and
Information” at the nearest address given on the Alarm or in
this leaflet. Do not snap on to the mounting plate as this
connects the battery and the unit may beep or alarm in the
post. State the nature of the fault, where the Alarm was
purchased and the date of purchase.

13. TROUBLESHOOTING
1. FREQUENT NUISANCE ALARMS OCCUR:
(1) Close kitchen / bathroom door when in use.
(2) Ensure that the alarm is sited at least 6m away from
sources of fumes.
(3) Contamination from insects, paint or paint fumes may have
occurred. Clean the alarm - see “CLEANING YOUR ALARM”
section on page 6.
(4) If the problem persists, resiting of the unit should be
considered.
2. ALARM SOUNDS FOR NO APPARENT REASON:
(1) Identify the alarm source. On interconnected units, the red
light on the cover will flash rapidly only on the unit which is the
source of the alarm. If an optional Ei1529RC Control Switch is
installed, press Locate when system is sounding to identify
source of alarm.
(2) Check for fumes, steam etc. from the kitchen or bathroom.
Paint and other fumes can cause nuisance alarms.
(3) Press the test/hush button to silence the Smoke/Heat
Alarm for 10 minutes.
(4) If alarm does not stop, switch off mains and remove unit -
see “ALARM REMOVAL” section on page 2. (Only remove
the alarm with the red light flashing, the others are probably
satisfactory).
3. LOW BATTERY & OTHER BEEPS:
(On Ei141/144/146 only)
If the battery is correctly connected and the unit has beeped
for over 20 minutes the battery is probably depleted. Obtain a
new battery, disconnect the mains, then remove the alarm
and replace the depleted battery.
(On Ei161RC/164RC/166RC only)
Check the green mains power light is on. If not, check fuse,
circuit breakers and wiring connections. If the green light is off,
the Lithium cells will deplete after some months without mains
and will need to be recharged. If turning on the mains fails to
stop the beeps, a fault may exist. Switch off mains and remove
the unit - see “ALARM REMOVAL” section on page 2.
(All Alarms)
(1) If the green mains light is on and replacing battery,
recharging Lithium cells or cleaning unit has not stopped the
11

13. TROUBLESHOOTING (CONTINUED)
beeps, a fault may exist. Disconnect the mains first and
replace the unit - see “ALARM REMOVAL” section on page 2.
(2) Ionisation Smoke Alarms (Ei141/161RC) and Heat Alarms
(Ei144/164RC) give two beeps 10 minutes after the test/hush
button is pressed.
(3) If an Optical unit (Ei146/166RC) beeps without the red
light flashing at the same time, the chamber is defective.
Clean the chamber.
4. INTERCONNECTED ALARMS DO NOT ALL SOUND:
(1) Hold test button for 10 seconds after first alarm has
sounded to ensure signal is transmitted to all units.
(2) One or more of the connections may not be correctly
connected.We recommend you consult a qualified electrician.
