Kidde Fyrnetics recom m ends for m axim um protection that both ionisation and opti-
cal (photo-electric) sm oke alarm s be installed. Ionisation technology is faster at
detecting fast flam ing fires that give off little sm oke. Optical (photo-electric) technology
is faster at responding to slow, sm ouldering sm oky fires. Heat alarm s are installed
in environm ents where excessive steam , dust etc. m ake sm oke alarm s im practical
e.g. kitchens/boiler room s/lofts.

b. Alarm Types
•
Ionisation (Ion) alarm s are the m ost com m on type and provide early detection,
especially against fast flam ing fires. Most suitable for dining and living room
areas. Ion alarm s contain 0.9 m icrocurie of Am ericium 241, a radioactive m aterial.
UK Hom e Office and BS5839 Pt6 recom m end however, that optical alarm s are also
used especially in locations where steam or cooking fum es, from a nearby room
could cause nuisance alarm s.
No one type of alarm is considered suitable for all locations.

Optical (Photo-Electric) alarm s are increasingly used and are less prone to nuisance
alarm s from cooking fum es. They are therefore the recom m ended type in BS5839
Pt6, for fitting near kitchen areas and on escape routes/circulation spaces.

Heat alarm s are for use in areas where Ion or Optical sm oke alarm s would be
unsuitable e.g. kitchens, boiler room s, garages. However, they m ust always be
used interconnected to sm oke alarm s – do not use in isolation. (They will typically
go into alarm when the tem perature reaches 57°C.) Suitable for new Building
Regulations applicable 1/7/2000 regarding use in kitchens.
4. How to Operate/Test the Alarm
a. Operation and L.E.D. Status
•
When your alarm is correctly installed to the m ains supply, the green L.E.D. light
will be on. The red L.E.D. will blink every 30-40 seconds to indicate the sensor is
operating correctly. If the alarm senses products of com bustion, it’s 85dB horn will
be activated. The red L.E.D. will flash rapidly on the alarm sensing sm oke/heat.
(Other interconnected alarm s will also sound to warn those in other parts of the
property.) This will continue until the sensor cham ber is clear.
In the case of a heat alarm , it will be triggered when the tem perature reaches 57°C
and return to it’s standby m ode when the tem perature drops to norm al levels. On
optical alarm s if the red L.E.D. blinks every 30-40 seconds and the alarm chirps
inbetween, it indicates failure of the sensing cham ber.
Regularly check and ensure that the green L.E.D. is lit – if not, check the consum er
unit/ circuit breaker connection. As w ith previous point above, if in doubt, consult
an electrician or your Landlord.

b. Testing
Utilise the test button to test the alarm . Do not use naked flam es as this does not
•
replicate sm oke and m ay cause physical dam age to the alarm .
Test all your alarm s w eekly – rem em ber they are life saving devices, protecting
the fam ily and hom e.
Press and hold the test button until the alarm sounds. All interconnected alarm s
will also sound. (Do not stand too close to the alarm during testing – hearing m ay
be dam aged.)
c. Hush Button
This feature tem porarily desensitises the alarm circuit for approxim ately 7 m inutes.
This feature is to be used only when a known alarm condition, such as fum es
from cooking, activates the alarm . The alarm is desensitised by pushing the
“HUSH” button on the alarm cover. If the sm oke is not too dense, the alarm will
silence im m ediately and “chirp” every 30-40 seconds for approxim ately 7 m inutes.
This indicates that the alarm is in a tem porarily desensitised condition. The alarm
will autom atically reset after approxim ately 7 m inutes and sound the alarm if particles
of com bustion are still present. The “HUSH” feature can be used repeatedly until
the air has been cleared of the condition causing the alarm .
Note: Dense smoke will override the hush control feature and sound a continuous alarm.
Caution: Before using the alarm hush feature, identify the source of the sm oke and
be certain a safe condition exists. (On heat alarm s with hush, the alarm s sensor has
detected a high tem perature – e.g. 57°C. Check for possible causes
carefully.)
d. Nuisance Alarm s
Warning: Persistent nuisance alarm s indicates incorrect type and/or siting of
alarm . Review with your installer or Landlord after cleaning as described in
Section 7 (Maintenance).
5. Battery Checking/Changing*
Loose Battery Models
a. Low Battery Indicator (AC m odels with loose battery only)
If you hear the alarm chirp continuously every 30-40 seconds at the sam e tim e as
the led flashes (and have not just pressed the hush button) it indicates the battery
voltage is at an unacceptably low level. Replace the battery at the next possible
opportunity.
b. Battery Change
i. Firstly isolate the m ains supply at the consum er unit by identifying the appro-
priate circuit. This m ay be a dedicated fuse m arked “Fire/Sm oke Alarm s” or
with a sym bol such as

Good Safety Habits
(Section 11)
Develop and practice a plan of escape:
• Make a floor plan indicating all doors and windows and
at least two escape routes from each room . Second
storey windows m ay need a rope or chain ladder.
• Have a fam ily m eeting and discuss your escape plan,
showing everyone what to do in case of a fire.
• Determ ine a place outside your hom e where you can
m eet if a fire occurs.
• Fam iliarise everyone with the sound of the alarm and
train them to leave your hom e when they
hear it.
• Practice a fire drill at least every six m onths. Practice
allows you to test your plan before an em ergency. You
m ay not be able to reach your children.
It is im portant they know what to do.
What to do when the Alarm Sounds
(Section 12)
• Leave im m ediately by your escape plan. Every second
counts, so don’t waste tim e getting dressed or picking
up valuables.
• In leaving, don’t open any inside door without first feel-
ing its surface. If hot, or you see sm oke seeping through
cracks, don’t open that door!
Instead use your alternative exit.
• If the inside of the door is cool, place your shoulder
against it, open it slightly and be ready to slam it shut if
heat and sm oke rush in.
• Stay close to the floor if the air is sm oky.
Breathe shallowly through a cloth, wet if possible.
• Once outside, go to your selected m eeting place and
m ake sure everyone is there.
• Call the fire brigade on 999 from your neighbour’s hom e
or a call box – not from yours.
• Don’t return to your hom e until the fire officials say that
it is all right to do so.

6. Checking Battery Back-up on Rechargeable/Long Life Models
•
There is no user replaceable battery on rechargeable m odels. This will be indicated
on the product; additionally there is no battery com partm ent. To check charge
on these m odels, switch off the alarm s AC supply at the Consum er Unit/Fuse
Box. The green L.E.D. w ill go out. Push the test button to check battery only
m ode works. If the rechargeable battery is depleted, the low battery beep will be
heard once every 40 seconds. If the alarm has received AC m ains power for a
m inim um of 3 days prior to this, you will need to have the unit changed by your
installer or Landlord.
7. Maintenance
•
Your alarm is a life saving device. Spending a few m inutes
each m onth in vacuum ing off any excess dust will enhance it’s
perform ance and reduce the likelihood of nuisance alarm s.
•
Vacuum up to the grill and through the slots where dust/talc
etc. can enter. Wipe off with a very m ildly dam p cloth. Never
use cleaning agents/polishes etc..
N A
Never attem pt to open the inside of the alarm
– this w ill invalidate it’s guarantee.
8. What to do in an Emergency
•
•
•
If an alarm sounds without anyone pressing the test button you have a potential
em ergency.
Don’t panic – you will need to think clearly to ensure all fam ily m em bers escape
as soon as possible. Never stop to collect belongings etc. – they are replaceable.
Check the tem perature of door handles or doors to check if hot –
if hot do not open them – a fire will be raging the other side of the door.
Find an alternative escape route.
•
•
Keep doors/windows closed to contain the fire after you have passed through them .
Call 999 from a neighbour’s phone or call box.
This is preferable to using a m obile.
•
Do not re-enter the property until advised it is safe to do so by a Fire Brigade
Officer.
Always be aware of the dangers of fire and ensure your alarm s
are functioning, together with equipm ent such as
fire extinguishers/fire blankets etc..

10. Useful Hints
•
•
•
Sm oke/heat alarm s can only operate correctly if sm oke particles/ heat reach the
unit. Correct selection/siting and installation are covered in the installers m anual,
who fitted your alarm /s.
UK Building Regulations require new hom es to have 1 hard wired sm oke alarm
per floor and to be interlinked. During 2000 they will additionally require an
interlinked heat alarm to be fitted in m ost kitchens too. i.e. 3 alarm s per property.
With the exception of garages/kitchens/bathroom s it is recom m ended that
sm oke alarm s are fitted in every room and outside all sleeping areas too.
A professional electrician should be em ployed for all m ains powered (hard
wired) alarm s.
If you are redecorating your hom e, paint fum es can contam inate the alarm –
tem porarily cover the unit with a plastic bag (during this tim e the alarm will not
function). Never paint the alarm itself.
Only rem ove the bag when the paint is thoroughly dry.
If you extend your property, review your alarm requirem ents.
Sm oke/heat alarm s should be replaced every 10 years or sooner.
These products are designed for dom estically scaled prem ises.

13. Limitations of Smoke/Heat Alarms
Warning! Alarm s are devices that can provide early warning of possible fires at a rea-
sonable cost; however, alarm s have sensing lim itations. Ionisation type alarm s offer a
broad range of fire sensing capability but are better at detecting fast flam ing fires
than slow sm ouldering fires. Optical (Photo-electric) alarm s sense slow sm ouldering fires
better than flam ing fires. Hom e fires develop in different ways and are often unpre-
dictable. Neither type of alarm (Photo-electric or Ionisation) is always best, and a
given alarm m ay not always provide warning of a fire.
Heat alarm s are triggered when a tem perature of 57°C is reached – they m ust always
be used in conjunction and interconnected to sm oke alarm s.
Loose batteries, where fitted m ust be of the specified type, in good condition and
installed properly.
AC only powered alarm s will not operate if AC power has been cut off such as by an
electrical fire, an open fuse or loss of m ains supply.
All alarm s m ust be tested regularly to m ake sure the batteries and the alarm circuits
are in good operating condition.
Sm oke alarm s cannot provide an alarm if sm oke does not reach the unit. Therefore,
sm oke alarm s m ay not sense fires starting in chim neys, walls, on roofs, on the other
side of a closed door or on a different floor. If the alarm is located outside the bed-
room or on a different floor, it m ay not wake up a sound sleeper. Equally heat alarm s
will only be triggered if they are correctly sited to detect heat. The use of alcohol or
drugs m ay also im pair ones ability to hear the alarm . For m axim um protection a sm oke
alarm should be installed in each sleeping area on every level of a hom e. Hearing
im paired occupiers should consider fitting additional strobe accessories to give a
visual alarm .
Although sm oke/heat alarm s can help save lives by providing an early warning of a
fire, they are not a substitute for an insurance policy. Hom e owners and renters
should have adequate insurance to protect their property.
If after reviewing this m anual you feel that your sm oke alarm is defective in any way,
do not tam per with the unit. Return it prepaid for servicing to: Kidde Safety Europe,
Mathisen Way, Colnbrook, SL3 0HB, UK – Em ail: info@kiddesafety.co.uk, or refer to
your installer or Landlord.
