LOCATING ALARMS

SMOKE ALARMS

Sufficient smoke must enter the Smoke Alarm before it will
respond. The Smoke Alarm needs to be within 7.5 metres (25
ft) ofthe fire to respond quickly.It also needs to be ina position
where its alarm can be heard throughout your home, so it can
wake the occupants in time for all to escape. A single Smoke
Alarm will give some protection if it is properly installed, but
most homes will require two or more to ensure that a reliable
early warningis given. For maximum protection youshould put
individual Smoke Alarms in all the rooms where fire is most
likely to break out, (apart from kitchens, bathrooms etc. see
Locations to Avoid).

A Smoke Alarm should be located between the sleeping area
and the most likely sources of fire (living room or kitchen for
example).It should not be morethan 7.5 metres (25ft) from the
door to any room where a fire might start on the escape route
from the house.

Important: These Smoke/Heat Alarms are designed for a
single occupancy in a residential type environment.

ASmoke Alarm should be sitedwithin 3m of bedroom doorsfor
improved audibility.

HEAT ALARMS

The Heat Alarm gives a fire warning when the temperature at
the unit reaches 58°C. It is ideal for kitchens, garages, boiler
housesand other areas where thereare normally high levelsof
fumes, smoke or dust i.e. places where Smoke Alarmscannot
be installed without the risk of excessive nuisance alarms.

A Heat Alarm should only be used in a room adjoining an
escaperoute, in conjunction with SmokeAlarms on the escape
routes.

All the Heat Alarms and Smoke Alarms should be
interconnected to ensure the early warning will be heard,
particularly by somebody sleeping. A properly designed early
warning fire system ensures the alarm is given before the
escape routes become blocked with smoke. Therefore, there
must be Smoke Alarms along the escape routes as Heat
Alarms would not give sufficient warning. However, a fire in a
closed room (e.g. kitchen) adjoining the escape route, can
eventually cause the corridor to become smoke-logged due to
smoke leaking out from around the door before adequate
warning can be given by detectors in the corridor. (Smoke
leaking outfrom a room is often cool andslow moving so it can
take a long time to rise to the ceiling, and travel to a detector
which could be some distance away). A Heat Alarm in the
closed roomwill give early warning of firein that room and help
overcome this problem.

RECOMMENDED LOCATIONS

Figure 2 illustrates where Smoke Alarms and Heat Alarms
should be located in a typical two storey house. Note the
spacingsin “Recommended Protection” whichensure the early
detection of fire and the warning will be heard.

Locate Heat Alarms in rooms adjoining or on escape routes ­kitchens, garages,boiler houses etc. where SmokeAlarms are
unsuitable. Install within 5.3m (17 feet) of potential sources of
fire.

Single Storey Dwelling.

If the Home is on one level (a bungalow or mobile home for
example) you should put the firstSmoke Alarm in a corridor or
hallway betweenthe sleeping and living areas. Placeit as near
to the living area as possible, but make sure you can hear it
loudlyenough to wake a personin the bedrooms. (forexample,
see figure 3) Single storey Dwelling with Recommended
ProtectionSingle Storey Dwelling with Recommended
Protection

Ifthe bungalow is very largeand the corridor or hallwayis more
than say 15 metres (50 ft) long, one Smoke Alarm will not be
sufficient.This is because no matterwhere it is located itwill be
more than 7.5 metres from potential fires.

In houses with more than one sleeping area, Smoke Alarms
should be placed between each sleeping area and the living
area.

Multi Storey Dwellings

If the dwelling has more than one storey it must have an
interconnected alarm on each level for minimum protection.

Maximum Protection

For maximum protection you should put individual Smoke
Alarms in all the rooms where fire is most likely to break out
(apart from the locations to avoid, mentioned below). Ensure
that they are all interconnected. The living room is the most
likelyplace for a fireto start atnight, followed by thekitchen and
then the diningroom. You should also consider putting Smoke
Alarms in any bedrooms where fires might occur, forinstance,
where there is an electrical appliance such as an electric
blanket or heater, or where the occupant is a smoker. You
could alsoconsider putting Smoke Alarms in any rooms where
the occupant is unable to respond very well to a firestarting in
the room, such as an elderly or sick person or a very young
child.

Fire Authorities (including the Home Office, UK) recommend
that both Optical and Ionisation Smoke Alarms should be
fitted for the fastest response to all types of fires. An Optical
Alarmshould be located downstairsto detect slow smouldering
fires (e.g. from a cigarette burning in a couch or bedding,

overheated PVC wiring etc). An Ionisation Alarm should be
located upstairs to detect fast flaming fires (e.g.paper burning
ina container or agrease fire in thekitchen) which couldrapidly
block the main escape route.

Checking you can hear the Smoke & Heat Alarms

With theAlarm sounding in its intendedlocation, check you are
able tohear it in each bedroom withthe door closed, above the
soundof the radio. Theradio should beset to a reasonablyloud
conversation level. If you can’t hear it over your radio the
chances are that it wouldn’t wake a person.

If a Smoke Alarm is too far away for it to wake a person, it is
best to interconnect to another Smoke Alarm or Heat Alarm
near the bedroom, so when one alarm senses fire, all
interconnectedalarms respond (seebelow for further details).

LOCATIONS TO AVOID

Don’t place Smoke Alarms in any of the following areas:

•

Bathrooms, kitchens, shower rooms, garages or other
rooms where the smoke alarm may be triggered by steam,
condensation, normal smoke or fumes. Keep at least 6
metres (20 feet) away from sources of smoke.

Don’t place Heat Alarms in any of the following areas:

•

Bathrooms, shower rooms or other room where the unit
may be triggered by steam or condensation.

Don’t place Smoke or Heat Alarms in any of the following
areas:

•

Places where the normal temperature can exceed 40°C
(104°F) or be below 4°C (39°F) e.g. attics, furnace rooms
etc. directly above ovens or kettles, as the heat/steam
could cause nuisance alarms.

•

Near a decorative object, door, light fitting, window
moulding etc., that may prevent smoke or heat from
entering the Alarm.

•

Surfacesthat are normally warmeror colder than therest of
the room (for example attic hatches, uninsulated exterior
walls etc). Temperature differences might stop smoke or
heat from reaching the unit.

•

Next to or directly above heaters or air conditioning
vents, windows, wall vents etc. that can change the
direction of airflow.

•

In veryhigh or awkward areas (eg. over stairwells) where it
may be difficult to reach the alarm (for testing, hushing or
battery replacement).

• Locate away fromvery dusty or dirtyareas as dust build-up
inthe chamber can impair performance.It can also blockthe
insect screen mesh and prevent smoke from entering the

smoke detector chamber.

•

Locate the unit at least 1 metre (3 feet) from dimmer
controlled lights and wiring - some dimmers can cause
interference.

•

Locate unitat least 1.5m (5 feet) androute wiring at least 1m
(3 feet) away from fluorescent light fittings as electrical
“noise” and/or flickering may affect the unit.

•

Donot locate in insect infestedareas. Small insects getting
into the smoke detector chamber can cause intermittent
alarms. Insects and contaminationon the HeatAlarm sensor
can increase its response time.

POSITIONING SMOKE/HEATALARMS

Thelocations must complywith applicable building regulations.

Hotsmoke rises and spreadsout, so acentral ceiling position is
the preferred location. The air is “dead” and does not move in
corners, therefore Smoke & Heat Alarms must be mounted
away from corners. Place the unit at least 300mm (12 inches)
from any light fitting or decorative object which might obstruct
smoke / heat entering the Alarm. Keepat least 300mm (12”)
away from walls. See figure 4. (Smoke Alarms should be
located directly on the ceiling or up to 570mm below it. Heat
Alarms should belocated directly on the ceiling or up to 90mm
below it).

Wall mounting is not recommended for these Alarms.

Sloping Ceiling

In areas with sloping or peaked ceilings install your
Smoke/Heat Alarm 90mm (3 feet) from the highest point
measured horizontally(see figure 5), because “dead air” at the
apex may prevent smokefrom reaching the unit.

INTERCONNECTING SMOKE/HEAT

ALARMS

When a fire is sensed the alarm must be given throughout the
house. Up to twenty (20) Smoke Alarms (models EI 180, 181,
185, 186 only) and Heat Alarms (model EI 183, 184 only) can
be interconnected so that when one senses fire all alarm.
Caution: Do not interconnect to any other type of alarm.
The unitinitiating the alarm can be identifiedby the red LED on
the cover flashing every second. Figure 6 shows the
interconnect wiring.

Note:It is only necessaryto wire one relayto the control panel.
If any alarm senses fire this relay will change state due to the
signal on the interconnect line.

These Alarms should be interconnected only within the
confines ofa single family living unit. If theyare interconnected
between different units there may be excessive nuisance
alarms.Everybody may not beaware that they arebeing tested
or thatit is a nuisance alarm caused bycooking etc. When one
unit alarms all relays will switch.

Systems using more than 3 or 4 alarms must be verycarefully

planned to ensure nuisance alarms are not excessive, e.g.
from cooking or weekly testing.

Smoke Alarm Locator Switch (EI 159) should be incorporated
into the system and be readily accessible to all occupants so
that the source of an alarm can be quickly identified. (see
Accessory section).

All Alarms must be cleaned and maintained regularly.

A competent person must be on call to quickly remove any
faulty alarms (i.e. units with red light flashing), which are
causing all alarms to sound.

INSTALLING SMOKE/HEAT ALARMS

The Alarm is designed to be permanently mounted , using it’s
own built-in terminal blocks to connect it to the panel. The
mounting plate can be screwed directly to the ceiling after
connecting the wires.

IMPORTANT PRECAUTION:Do not install the actual alarm
itself in new or renovated buildings until all work is
completed(including floor coverings) andthe building has
been fully cleaned. The wiring can be installed when
appropriate. (Excessive dust and debris from building
work can contaminate the smoke chamber or heat sensor
and cause problems, it will also invalidate the guarantee).
If it must be installed, cover it completely, particularly
around the edges, with a dust cover (eg. with the
elasticated cover supplied or a plastic bag), until all
cleaning is finished.

Warning: Wiring should only be installed by an Electrician in

accordance with current IEE wiring regulations for electrical
installation. The installation must also be in accordance with
thecontrol panel instructionsand the instructions inthis leaflet.

Warning: The mains circuit used to power the control panel
must be a 24 hour voltage circuit and be wired on a separate
circuit (one with no other lights or applilances) to ensure
maximum reliability of the supply.

Warning: The Alarms must be connected to a panel that
supplies a permanent voltage that cannot be switched off.

Warning: For safety reasons the voltage supply from the
control panel must not be greater than 30V (peak or d.c.) and
mustbe either independentof the supply mainsor isolated from
it by double or reinforced insulations.

Warning:If the control panelis not provided withan ALL-POLE
MAINSSWITCH (with a contactspecification of at least3mm in
each pole), then the electrical installation of the building shall
incorporate an ALL-POLE MAINS SWITCH, (with a contact
separation of at least 3mm in each pole).

Installation

Select a location complying with the above advice.

1. Remove the mountingplate from the Smoke Heat Alarm by
releasing the tamper-proof catch with a small screwdriver as
shown in figure 1a and sliding the alarm from the plate.

2.Lift the foam flap coveringthe circuit on themounting plate. If
necessary movethe jumpers on S1 and/or S2 (seefigure 7) by
carefully lifting them and placing them over the required pins.

3. If surface wiring the unit remove the required breakaways.
Low voltage signal cable is satisfactory (e.g. wire 0.22mm

2

)
provided theresistance between the units andthe panel is less
than 20 ohms.

All wiring must comply with local codes. Connect the wires to
the terminals as shown in the wiring diagram (figure 6). The
gasket flap can be tucked behind the terminals while this is
being done. Place gasket flap back over circuit board and
terminals.

4.Carefully align the mounting plateand screw into place. With
recessed wiring,ensure the rear gasket seals around theedge

ofthe hole in theceiling. This isto prevent air draughtsaffecting
the smoke / heat entering the alarm. If the orifice is toolarge it
should be sealed with silicone rubber or equivalent.

Check the battery is connected in the back of the alarm ( EI
181, 184, 186 only).

Carefully line up the unit on the base and slide on.

Press the test/hush button for 10 seconds. The horn should
sound (EI 181, 184, 186 only).

7. Connectthe panel power to thealarm circuit. The green light
on the mounting plate should turn on.

Check the operation of the Alarm as outlined in the next
section.

CHECKING AND MOUNTING YOUR

ALARMS

INSPECTION & TESTING PROCEDURE

After installation, after re-occupation following a holiday, and
weekly, check all your Alarms as follows:

Check thegreen light is illuminated onthe mounting plate. This
shows the panel is supplying power.

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 relay
contacts should change over with the EI185, EI186 relay
contacts when the horn sounds with the EI180, EI181, EI183,
EI184, it contacts within 6 seconds after the horn sounds. The
alarm 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.

Wedo not recommend testingwith smoke orheat as theresults
can be misleading unless special apparatus is used.

Check for any sign of contamination such as cobwebs or dust
and clean the alarm as described below if necessary.

Interconnected alarms

Test the first unit by pressing the button. All the detectors
should alarm within about 5seconds of the first horn sounding
and the red light on the first unit only will flash once a second.
The relay contacts should change over about 6 seconds after
the horns sound. Check all the other units similarly. (Note:
Ionisation and Heat alarms signal to other interconnected
alarms, about 4 seconds after their own horn sounds. Optical
alarms signal within about a second).

Checking Battery Back-up

TheAlarm automatically monitors thebattery every 40seconds
toensure that it is satisfactory.If it is depleted itwill give a short
beep every 40 seconds (models EI 181, EI 184 and EI 186
only).

Before replacing the battery, check that the beeps arenot due
to one of the following:

(i) Battery snaps not connected properly.

(ii) On the OpticalSmoke Alarms only (EI 186/185) 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
the Smoke Alarm section below:

If the beepshave continued for over 20 minutes (and the other
causes of beeps have been ruled out – see below) the battery
must be replaced.

(iii) Switch off the panel voltagesupply and remove the unit as
shownin fig 1a. CAUTION:Do not attemptto remove the Alarm
withoutfirst releasing the tamperclip. Remove depletedbattery
and replacewith one of the specified 9Valkaline batteries. The
alarm cannot be replaced on the mounting plate unless a
battery is installed. After replacing the battery, slide on to the
mounting plateand then press the test button and ensure horn
sounds loudlybefore you turn on the panel supply. Note: Only
use the specified Alkaline batteries shown on the base label
(Duracell MN1604, Eveready 522 or Energizer 6LR61). 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.

We recommend that the battery is replaced each year for
optimum performance.

Please note:The ionisation and heat alarms (EI180, 181,183
and 184)give two short beeps about a secondapart at the end
of the hushperiod (i.e. about 10 minutes after test/hush button
has been pressed). These two beeps should not be confused
with low battery beeps.

Manual Testing

We recommend that the functioning of the battery back-up is
checked after installation and then at least yearly as follows:-

Turn off (or disconnect) the power at the panel (green light on
mounting plate should beoff) press the test button and ensure
thehorn sounds loudly for10 seconds. (This checksthe battery
back-up models EI 181, EI 184 and EI 186 only).

Note: A good battery can supply the unit for over a year in
standby (or 5 hours in alarm) without panel power.

Instandby, with panel power,the battery canoperate for up to4
years before the low battery beeps start – these will normally

last for over 30 days before the battery is fully depleted.

CLEANING YOUR ALARM

Clean yourAlarm 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
wherethe smoke orheat enters. To cleanthe cover, wipewith 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 buildup. Any insects or cobwebs inthe 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 isnot covered by the guarantee and a charge is
made for servicing suchunits.

If you experience persistent false alarms, in particular
locations, due to contamination of the smoke chamber you
could consider replacing Optical Smoke Alarms (EI 186/185)
with Ionisation Smoke Alarms (EI 181/180). Ionisation type
alarms are less susceptible to dust than Optical type alarms.

NUISANCE ALARMS

If there is a nuisance alarm simply press the test/hush button
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 getyour family
into a safe place, before you start investigating.

Check the house carefully in casethere is a small fire smould­ering somewhere.

Check whether there is some source of smoke or fumes, for
example cookingfumes being drawn past the Smoke Alarmby
an extractor.

Ifthere are frequent nuisance/false alarmsit may be necessary
tore-locate the device away fromthe source of the fumes.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
figure 1). If cleaning the Alarm does not correct the problem it
can be returned to the manufacturer for repair or replacement
(see Getting Your Alarm Serviced below).

Hush Feature

All the Smoke / Heat Alarms have a combined Test/Hush
Button to help you control nuisance false alarms.

1. Tocancel 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 willoverride the Hush on thesmoke 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
reduced. At the end of the hush period the Ionisation
SmokeAlarm (EI 181/180) and theHeat Alarms (EI 184/183)
will give two short beeps. The Optical Smoke Alarm (EI
185/186) does not give these two 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. Pressingthe 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.

IMPORTANT SAFE GUARDS

•

When using household protective devices, basic safety
precautionsshould 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 entitled“Smoke Detectors in the Home” (FB2) or
from your local fire prevention officer.

•

NOTE: Constant exposure to high or freezing temperatures
or high humidity may reduce the life of the battery.

•

Tomaintain sensitivity to smoke,do not paint orcover smoke
/heat alarms inany manner; do not permit any accumulation
of cobwebs, dust or grease.

• If a unit has been damaged in any way or does not function
properly,do notattempt a repair. Return Alarm (see- Getting
your Alarm Serviced).

•

This appliance is only intended for premises having a
residential type environment.

•

Smoke / HeatAlarms are not a substitute for insurance. The
supplier or manufacturer is not your insurer.

•

The chamber inside the Ionisation Smoke Alarms (EI
181/180)contains a small amountof radioactive material. Do
not tamper with the chamber. You may safely install and
clean the Smoke Alarm following this leaflet’s instructions.

•

In the United Kingdom Ionisation Smoke Alarms can be
disposed of in normal household refuse, but due to the tiny
amountof radioactive material contained inthe unit, no more
than one alarm per dustbin.

•

In theRepublic of Ireland Ionisation smokealarms should be
returnedfor disposal to the nearestaddress at the endof this
leaflet.

Do not dispose of your Alarm in a fire.

Use the Smoke / Heat Alarm Test Buttons to familiarize 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 tendto hide when they don’t know what to do.
Teach children how to escape, open windows, and use roll up
fire laddersand stools without adult help.Make sure they know
what to do if the alarm goes off - see next page.

PLANNING YOUR ESCAPE FOR WHEN THE

ALARM GOES OFF

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 neighb
our’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 independentauthorities have stated that theymay 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
back-up battery is depleted. On the EI181/184/186 alarms
the batteries should be replaced annually and whenthe unit
gives low battery beeps.

•

Smoke/Heat Alarms will not detect fire if sufficient smoke/
heat does not reach the alarm. Smoke/Heat may be
prevented from reaching theAlarm 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 carrythe smoke/heat away. Installing Smoke/Heat
Alarms on both sides of closed doors and installing more
than oneSmoke/Heat Alarm as recommended in this leaflet
very significantly improves the probability of early detection.

•

The Alarm may not be heard.

•

ASmoke / Heat Alarmmay not wake aperson who hastaken
drugs or alcohol.

•

Smoke/ Heat Alarms maynot detect every typeof fire to give
sufficientearly warning. They areparticularly ineffective with:
fires caused by smoking in bed, escaping gas, violent
explosions, poor storage of flammable rags and/or liquids,
(for example petrol, paint, spirits etc), overloaded electrical
circuits, arson and children playing with matches.

•

Fire Authorities(including the Home Office, UK) 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.

The manufacturer recommends replacement of the Smoke/
Heat Alarms after 10 years as a precaution.

ACCESSORY

Smoke Alarm Locator EI 159:

The Smoke Alarm locator is recommended for systems with
three or more Smoke / Heat Alarms as it helps quickly identify
the unit in alarm and reduces the impact of nuisance alarms.

Pressing the Smoke Alarm Locator button will silence all
interconnected alarms for 10 minutes, except those sensing
fire. It is easily installed between the interconnect and 0 volt
terminals.

GETTING YOUR ALARM SERVICED

If your Alarm fails to work after you have carefully read all the
instructions, checked theunit has been installed correctly, and
is receiving panel power contact Customer Assistance at the

TROUBLESHOOTING

1. FREQUENT NUISANCE ALARMS OCCUR:

(1) Close kitchen / bathroom door when in use.

(2)Ensure that thealarm is sited atleast 6m awayfrom sources of
fumes.

(3) Contamination from insects, paint or paint fumes may have
occurred. Clean the alarm as described in this booklet.

(4) If the problem persists, resiting of the unit should be
considered. Alternatively, replace the unit with an Optical unit
(EI186/185), assumingthat the problem is with anIonisation type
alarm (EI181/180).

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.

(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, remove the unit (see figure 1). (Only
remove alarm with red light flashing, the others are probably
satisfactory).

3. LOW BATTERY BEEPS:

(On EI 181/184/186 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, remove thealarm and replace the depleted battery. (see
figure 1).

OTHER BEEPS:

(1) If the panel is providing power and replacing battery or
cleaning unit has not stopped beeps, a fault may exist. Replace
the unit (see figure 1).

(2) The Ionisation/Heat units (EI 181/180/184/183) give two
beeps 10 minutes after the test/hush button is pressed.

(3) If the Optical units (EI 186/185) beep without the red light
flashing at the same time, the chamber is defective. Clean the
chamber.

4. INTERCONNECTED ALARMS DO NOT ALL SOUND AND
THE RELAY DOES NOT SWITCH:

(1) Hold test button for 10 seconds after first alarm has sounded
to ensure signal is transmitted to all units. Relay should switch.

(2)Check that thegreen power light onthe mounting plateis on.

(3) Check panel and wiring.
