Thank you for choosing a Kidde Fyrnetics alarm.
Please read through our guide in full. It should be retained for future reference.
Cut out page 6 and pin up near your Consumer Unit/Fuse Box.
Kidde Fyrnetics recommends for maximum protection that both ionisation and
optical (photo-electric) smoke alarms be installed. Ionisation technology is
faster at detecting fast flaming fires that give off little smoke. Optical (photo-
electric) technology is faster at responding to slow, smouldering smoky fires.
Heat alarms (hard wired only) are installed in environments where excessive
steam, dust etc. make smoke alarms impractical e.g. kitchens/boiler
rooms/lofts.
Electrical rating 9V DC,
80mA max per alarm
with 12 alarms interconnected).

2. Important Information
•Test the alarm weekly by pressing (and holding) the test button.
The alarm and all those interconnected to it will sound.
•Vacuum your alarms regularly to reduce the likelihood of nuisance
alarms, caused by dust contamination.
•Never paint or expose alarm to water.
•If the alarm chirps every 30-40 seconds, it indicates the battery needs
replacing. (If you are in rented property, you may need to tell your
Landlord.)
Smoke and heat alarms will only function if properly selected, located,
installed and maintained as per KIDDE Fyrnetics instruction manuals.
3. Types of Alarm
a. Power Supply
•DC alarms
9V battery powered units, but will only function if battery is in good
condition –check regularly. (BS5839 Pt6: Grade F).
b. Alarm Types
•Ionisation (Ion) alarms are the most
common type and provide early
detection, especially against fast
flaming fires. Most suitable for
dining and living room areas. Ion
alarms contain 0.9 microcurie of
Americium 241, a radioactive
material. UK Home Office and
BS5839 Pt6 recommend however,
that optical alarms are also used
especially in locations where steam
or cooking fumes, from a nearby
room could cause nuisance alarms.
No one type of alarm is considered
suitable for all locations.
•Optical (Photo-Electric) alarms are
increasingly used and are less
prone to nuisance alarms from
cooking fumes. They are therefore
the recommended type in BS5839
Pt6, for fitting near kitchen areas
and on escape routes/circulation
spaces.

8. Initial Testing and Checking of Alarm
•Having energised by activating the battery circuit, press and hold the test
button again –the alarm should sound and other interconnected ones also,
within a few seconds.
•Do this for all alarms.
•If any do not sound, isolate mains and recheck cabling.
•On optical alarms if the red L.E.D. blinks every 30-40 seconds and the
alarm chirps inbetween, it indicates failure of the sensing chamber. Consult
your installer/supplier as appropriate having read the manuals
troubleshooting tips.
9. Interconnecting
•You may interconnect up to 11 Kidde Fyrnetics DC smoke or CO alarms to
this unit. i.e. 12 in total.
•Total cable length between alarms must not exceed 250m (273yds) and be
of 12V bell wire type, with a maximum resistance of 50Ωbetween alarms.
10. How to Operate/Test the Alarm
a. Operation and L.E.D. Status
•When your alarm is correctly functioning, the red L.E.D. will blink about
once a minute. If the alarm senses products of combustion, it’s 85dB horn
will by activated. The red L.E.D. will flash rapidly on the alarm sensing
smoke/heat. (Other interconnected alarms will also sound to warn those in
other parts of the property.) This will continue until the sensor chamber is
clear. On optical alarms if the red L.E.D. blinks every 30-40 seconds and the
alarm chirps inbetween, it indicates failure of the sensing chamber. (See
side or rear of alarm that indicates type.)
Regularly check and ensure that the L.E.D. is blinking – if not, check the
battery – on Sealed in/Long Life units consult your supplier/Landlord.
b. Testing
•Utilise the test button to test the alarm. Do not use naked flames as this
does not replicate smoke and may cause physical damage to the alarm.
Test all your alarms weekly –remember they are life saving devices,
protecting the family and home.
Connect (+) to (+) on each alarm and (–) to (–).

Good Safety Habits
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 may need a rope or chain ladder.
•Have a family meeting and discuss your escape plan,
showing everyone what to do in case of a fire.
•Determine a place outside your home where you can meet
if a fire occurs.
•Familiarise everyone with the sound of the alarm and train
them to leave your home when they
hear it.
•Practice a fire drill at least every six months. Practice
allows you to test your plan before an emergency. You may
not be able to reach your children.
It is important they know what to do.
What to do when the Alarm Sounds
•Leave immediately by your escape plan. Every second
counts, so don’t waste time getting dressed or picking up
valuables.
•In leaving, don’t open any inside door without first feeling
its surface. If hot, or you see smoke 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
smoke rush in.
•Stay close to the floor if the air is smoky.
Breathe shallowly through a cloth, wet if possible.
•Once outside, go to your selected meeting place and make
sure everyone is there.
•Call the fire brigade on 999 from your neighbour’s home or
a call box –not from yours.
•If there is any question as to the cause of an alarm, it
should be assumed that the alarm is due to an actual fire
and the dwellings should be evacuated immediately

8
Press and hold the test button until the alarm sounds. Any interconnected
alarms will also sound. (Do not stand too close to the alarm during testing –
hearing may be damaged.)
c. Hush Button
•If your alarm has this feature it has the capability of temporarily
desensitising the alarm circuit for approximately 7 minutes. This feature is
to be used only when a known alarm condition, such as fumes from
cooking, activates the alarm. The alarm is desensitised by pushing the
“HUSH”button on the alarm cover. If the smoke is not too dense, the alarm
will silence immediately and “chirp”every 30-40 seconds for approximately
7 minutes. This indicates that the alarm is in a temporarily desensitised
condition. The alarm will automatically reset after approximately 7 minutes
and sound the alarm if particles of combustion 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
smoke and be certain a safe condition exists.
d. Nuisance Alarms
Warning: Persistent nuisance alarms indicates incorrect type and/or siting of
alarm. Review with your installer or Landlord after cleaning as described in
Section 7 (Maintenance).
11. Battery Checking/Changing*
a. Low Battery Indicator
If you hear the alarm chirp continuously every 30-40 seconds
(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. On Sealed in/Long Life models there are no user replaceable
parts. Consult your supplier or Landlord, having read through the manuals
troubleshooting tips.
b. Battery Change
i. Pull out with pliers, the locking pin and retain for reinserting later.
ii. Twist alarm as indicated on housing to remove from mounting
base plate.
*On Sealed in/Long Life models there are no user serviceable
batteries to be changed. (See Section ?.)

9
iii. Flip up lid and note position of red plastic bar, under battery. When you
remove battery, the red door stop bar prevents the door closing unless a
battery is reinstalled.
This safety feature also prevents the alarm from being mounted back on
its mounting base plate.
We recommend the use of alkaline or lithium batteries for a longer
service life.
Battery type/code nos.
Alkaline type: Eveready 522; Duracell MN1604; Duracell Ultra MX1604;
Gold Peak 1604A;
Lithium type: Ultralife U9VL
On Sealed in/Long Life models there are no user serviceable
batteries to be changed. (See Section ?.)
vi. When you have fitted a fresh battery, check test button; if horn sounds
then reverse the process above.
12. Timing of Installing/Decorating
•Do not install if property remains damp/unheated.
•During building work dust and other contaminants e.g. paint fumes, will
enter the alarm causing possible nuisance alarms and damage the sensitive
components within. (It will also invalidate the guarantee provisions.) Cover
with a dust cover or plastic bag.
•After work is complete, allowing 3 days for paint fumes to clear, uncover
the alarm –this must be removed for the alarm to function.
13. Decorating
•Never paint the alarm itself.
•During redecoration, all alarms should be covered with a dust cover or a
plastic bag to prevent contamination by fumes.
(These can permanently damage the alarm).
Do not uncover until the surrounding paintwork is thoroughly dried and
fumes have cleared –allow 3 days.
•Whilst covered, the alarm cannot operate.
Remove covering as detailed above.
Red Battery Flag

14. L. .D. Status
•The red L.E.D. blinks to indicate normal operation of alarm function.
(If model with battery back-up, also indicates healthy battery.) In alarm state
(i.e. triggered), L.E.D. will flash rapidly. If interconnected to other alarms
only the triggering alarm will have a rapidly flashing L.E.D.. On optical
alarms if the red L.E.D. blinks every 30-40 seconds and the alarm chirps
inbetween, it indicates failure of the sensing chamber. Householders should
consult Owner’s Manual or installer/landlord.
•The alarm sounder and flashing L.E.D. will remain whilst the alarm
continues to detect smoke.
15. Ongoing Maintenance
•Alarms are sensitive electrical devices. The test button should be pushed
(and held) once a week to verify operation.
•Once a month the alarm should be wiped with a mildly damp cloth, having
previously vacuumed the outside of the unit, especially through the
grill area.
16. Checking Battery on Sealed in/Long Life Models
•There is no user replaceable battery on Sealed in/Long Life models. These
models will be indicated on the product’s label on the underside;
additionally there is no battery drawer. To check charge on these models,
push and hold the test button to check battery works. If the battery is
depleted, the low battery beep will be heard once every 40 seconds.
Deactivation: The alarms battery will chirp as detailed
above, when its power is low. If this lasts over 60
minutes, and is not a result of the HUSH button
being pressed, the alarm needs replacing.
However, to enable you to silence the
alarm, there is on the underside of the
alarm, a deactivation tab: see illustration.
To safely access the rear of the alarm, refer to Section 5.
17. Maintenance
•Your alarm is a life saving device.
Spending a few minutes each month in
vacuuming off any excess dust will
enhance it’s performance and reduce the
likelihood of nuisance alarms.
•Vacuum up to the grill and through the slots where dust/talc etc. can enter.
Wipe off with a very mildly damp cloth. Never use cleaning agents/polishes
etc..

18. What to do in an mergency
•If an alarm sounds without anyone pressing the test button you have a
potential emergency.
•Don’t panic –you will need to think clearly to ensure all family members
escape as soon as possible. Never stop to collect belongings etc. –they are
replaceable.
•Check the temperature 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 mobile.
•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 alarms
are functioning, together with equipment such as
fire extinguishers/fire blankets etc..

20. Useful Hints
•Smoke alarms can only operate correctly if smoke particles reach the unit.
Correct selection/siting and installation are covered earlier in this manual.
•UK Building Regulations require new homes to have 1 hard wired smoke
alarm per floor and to be interlinked. During 2000 they will additionally
require an interlinked heat alarm to be fitted in most kitchens too. i.e. 3
alarms per property. These models are not suitable for this requirement.
•With the exception of garages/kitchens/bathrooms it is recommended that
smoke alarms are fitted in every room and outside all sleeping areas too.
A professional electrician should be employed for all mains powered (hard
wired) alarms.

12
•If you are redecorating your home, paint fumes can contaminate the alarm
–temporarily cover the unit with a plastic bag (during this time the alarm
will not function). Never paint the alarm itself.
Only remove the bag when the paint is thoroughly dry.
•If you extend your property, review your alarm requirements.
•Smoke alarms should be replaced every 10 years or sooner.
•These products are designed for domestically scaled premises.
21. Limitations of Smoke Alarms
Warning! Alarms are devices that can provide early warning of possible fires at a
reasonable cost; however, alarms have sensing limitations. Ionisation type alarms
offer a broad range of fire sensing capability but are better at detecting fast flaming
fires than slow smouldering fires. Optical (Photo-electric) alarms sense slow
smouldering fires better than flaming fires. Home fires develop in different ways and
are often unpredictable. Neither type of alarm (Photo-electric or Ionisation) is always
best, and a given alarm may not always provide warning of a fire.
Loose batteries, where fitted must be of the specified type, in good condition and
installed properly.
All alarms must be tested regularly to make sure the batteries and the alarm circuits
are in good operating condition.
Smoke alarms cannot provide an alarm if smoke does not reach the unit. Therefore,
smoke alarms may not sense fires starting in chimneys, walls, on roofs, on the other
side of a closed door or on a different floor. If the alarm is located outside the
bedroom or on a different floor, it may not wake up a sound sleeper. Equally heat
alarms will only be triggered if they are correctly sited to detect heat. The use of
alcohol or drugs may also impair ones ability to hear the alarm. For maximum
protection a smoke alarm should be installed in each sleeping area on every level of
a home. Hearing impaired occupiers should consider fitting additional strobe
accessories to give a visual alarm.
Although smoke alarms can help save lives by providing an early warning of a fire,
they are not a substitute for an insurance policy. Home owners and renters should
have adequate insurance to protect their property.
