latest additions to our product range.
IMPORTANT: This user manual
contains important information
regarding the operation of your FireAngel
smoke alarm. Ensure you read this user manual
fully before installing and operating the alarm.
If you are installing this smoke alarm for use by
others, you must leave this manual (or a copy
of it) with the end user.
SENSOR TECHNOLOGY
There are two main types of smoke alarm. The
SI-601 Standard Smoke Alarm uses an ionisation
type sensor to detect the presence of smoke.
Ionisation type smoke alarms are generally more
effective at detecting fast, aming res which
consume combustible materials rapidly and spread
re quickly.The SO-601 Toast Proof Smoke Alarm
uses an optical (photoelectric) type sensor which
is more effective at detecting slow burning res,
which can smoulder for hours before bursting into
ames.
TOAST PROOF = less sensitive to cooking
fumes. (Optical alarms are less prone to
nuisance alarms due to cooking fumes.)
For maximum protection, use both types of
smoke alarms on each level of your home

APPLICATION
WARNING: Your FireAngel smoke
alarm can be installed into a new
build property as additional protection to
an existing smoke detection system only. It
cannot be used as a substitute for a hard wired
system as required in new build properties. In
this type of property the building regulations
require alarms to be interlinked. You can
obtain further information from your local re
service or building control department at your
local council ofces. These sources generally
provide advice on new builds or projects that
require planning permission.
Your smoke alarm typically meets the minimum
requirements for family living units in existing
buildings, as long as at least one unit is installed on
each oor/level of your property.
In order to achieve the earliest re warning, we
recommend that a smoke alarm is tted in all rooms
where the temperature is normally between 4°C
(40°F) and 38°C (100°F).The type of smoke alarm
used in each location should be appropriate to the
environment. Check the section on ‘Positioning’ to
ensure that the smoke alarm is to be correctly
positioned for the particular dwelling into which it
is intended to be installed.
WARNING: The alarm positions
shown overleaf are based on typical
homes. Construction and layout of individual
dwellings will vary, so this should be regarded
only as a guide. Check with your local re
station for further guidance.

EXISTING HOMES
NOTE: Kitchens should be covered by a
self contained heat detector.

Multi-family or mixed occupant residence
(Tenancy building, student accommodation)
Your FireAngel smoke alarm can also be used in
individual ats and bedsits, providing the same
conditions are met as for a single-family residence.
However, there must already be a primary
re detection system that meets regulatory
requirements for common areas such as lobbies
and hallways.
Institutions and Hotels
This includes motels, hospitals, day care facilities,
long-term health care facilities, boarding houses
and dormitories. Your smoke alarm can be used
in individual sleeping/resident rooms, providing
the same conditions are met as for a single-
family residence. However, there must already
be a primary re detection system that meets
regulatory requirements for common areas such
as lobbies and hallways. Use of this smoke alarm
in common areas may not provide sufcient
re warning to residents or meet regulatory
requirements.
This smoke alarm is designed to operate as
standalone smoke alarm.
WARNING: This FireAngel smoke
alarm will not communicate with other
smoke alarms or re alarm systems. It is not
intended as a substitute for a complete alarm
system.
Mobile Homes and Caravans
This smoke alarm is suitable for use in mobile
homes and caravans.
Commercial and Industrial Premises
This smoke alarm is not intended for any non-
residential, commercial or industrial application,
nor for any other purpose than described above.

6
POSITIONING
Ionisation type smoke alarms are generally
more effective at detecting fast, aming res which
consume combustable materials rapidly and
spread re quickly.
Examples fast aming res = Ignited paper, aming
curtains and oil res
Optical (Toast Proof) smoke alarms are
less prone to false alarms from cooking fumes,
are therefore suitable for locations near kitchens.
However optical smoke alarms are more
susceptible to nuisance alarms from steam and
should not be located too close to bathrooms
and showers.
Examples of slow smouldering res = cigarette on
furniture and bedding, overheating electrical cables.
It is recommended that your FireAngel smoke
alarm is NOT to be tted in the following
locations:
• Bathrooms, shower-rooms, and other very
damp or humid areas, where the moisture can
cause unwanted alarms.
• Kitchens. Kitchens should be protected with
self-contained Heat Alarms, as the combustion
particles from cooking in kitchens will
result in unwanted alarms and permanent
contamination of the smoke alarm’s sensor.
• In areas where excessive dust or dirt could
contaminate the sensing chamber, making it
over sensitive or impairing smoke entry.
• In areas where the ambient temperature is not
controlled and may regularly drift below 4°C
(40°F) or above 38°C (100°F) e.g. unheated
buildings, open attic spaces.
• Very dirty, dusty or greasy areas.
• In very draughty areas, such as close to ceiling
fans or fresh air vents. Draughts can blow
smoke away from the alarm.
• In insect infested areas. Insects can clog
openings to the sensing chamber, preventing
smoke entry or causing unwanted alarms.

• Within 30cm (12”) of a uorescent light tting
which emits electrical ‘noise’ that can prevent
correct alarm operation.
• In wall positions that are more than 30cm
(12”) away from the ceiling (see ‘How to install
your smoke alarm’).
• In ‘dead air’ spaces (see following diagram).
• Within 30cm (12”) of light ttings or other
ceiling based obstructions.

WHAT ARE THE
LIMITATIONS OF MY SMOKE
ALARM?
Your FireAngel smoke alarm is designed to alert
you by sounding an alarm when it senses smoke,
i.e. it can only sense smoke and alert you if smoke
reaches it! If a re develops in an area remote from
the location of the smoke alarm, such as another
room or another level, smoke may not reach the
smoke alarm in sufcient time or quantity to sense
and alert you to the danger.
We recommend that as a minimum you install
both ionisation and optical smoke alarms on
every oor of your property. For comprehensive
coverage a smoke alarm should also be tted in
every room.
This smoke alarm cannot be used to provide
primary re detection in common areas used
by different residents such as blocks of ats and
hotels.The FireAngel smoke alarm may not alarm
before a re causes damage, injury or death, as the
smoke may not reach the smoke alarm in time.
Examples include smoking in bed and violent gas
explosions.This smoke alarm may not respond in
a reasonable time if it is not installed in the best
position, or if furniture or other obstacles are
located between the smoke alarm and the re.
WARNING: Your smoke alarm will
not operate without a battery installed.
Only batteries listed on page 14 should be
used and must be changed immediately when
the low battery signal is given or the unit will
fail.Test weekly, read and follow all instructions
or the unit will not operate properly.
Your FireAngel smoke alarm will advise you of a
low battery condition by emitting an audible ‘chirp’
every 40 seconds. When this occurs you must
change the battery in the unit within 7 days to
maintain correct operation.

9
IMPORTANT: Smoke alarms are designed to alert you with an audible alarm at a level
specied by the British Standard BS EN 14604: 2005. Closed doors, walls and high ambient
noise levels will reduce this level. Temporary or permanently impaired hearing may result in the
alarm not being heard. Stereos, trafc and other loud sources may also prevent the alarm being
heard. Heavy sleepers and residents under the inuence of alcohol or drugs may also not hear or
respond to the alarm.Test and check that you can hear the alarm in all circumstances. If in doubt
install additional smoke alarms as required.
WARNING: The Smoke alarm is not suitable for alerting hearing impaired residents.
We recommend that specially designed warning systems be installed that will alert hearing
impaired residents.
WARNING:The smoke alarm accompanying this manual employs the latest technology and
is independently tested as being compliant with all the relevant British Standards. However,
as with any electronic product it may fail and may not sense all types of re within sufcient time
to alert you of the danger and provide adequate time for your escape. In order to maximise your
level of safety always test your smoke alarm frequently to ensure it is in full working order. Your
FireAngel smoke alarm is only suitable for use
in domestic/ residential applications as covered
in this manual. It is not suitable for commercial
or industrial applications. It is designed to
sense smoke and alert you. It will not sense
carbon monoxide, ames, heat or gas. It will
not prevent or extinguish res.
This FireAngel smoke alarm has a limited life of 10
years and should not be considered as a substitute
for life or property insurance. Like all electronic
equipment, it can wear out or fail. It should be
tested weekly and replaced immediately in the
event of failure, and replaced every 10 years
regardless.

HOW TO INSTALLYOUR
SMOKE ALARM
IMPORTANT: Make sure you have
read and understood this manual
before installing your smoke alarm.
1Preparation
Attach the mounting plate to a ceiling or wall.
If the alarm is to be mounted on a wall, ensure the
mounting plate is aligned correctly. The mounting
plate has an arrow moulded into the plastic. This
indicates the orientation in which the mounting
plate should be installed. This ensures that when
the alarm is tted the vents will be central and
facing upwards.
Use the xing slots on the mounting plate as a
guide when marking the position of the drill holes.
With an appropriately sized drill, drill the holes and
insert the plastic xing anchors supplied (if needed).

3Install 9V Battery
IMPORTANT: Before installing your
smoke alarm the battery must be
removed from the alarm and the protective
wrapper on the battery should be removed.
The battery should then be retted. The
battery compartment has been designed to
prevent the battery being inserted incorrectly.
CAUTION: The horn is designed to
be loud to wake you in an emergency.
Avoid placing your ear close to the alarm
when installing battery.
Insert the battery that was provided with the
alarm making sure that the positive and negative
connections are in the correct position, see
diagram. The red LED on the front should now
ash once every 40 seconds to show the alarm
is active.
3 Install 9V Battery
NOTE: On rare occasions the alarm may sound
when the battery is rst installed. If this happens, see
Troubleshooting on page 23.
Ensure wrapper is removed

13
The backing plate has a safety mechanism which
prevents the alarm being installed without a
battery. When the battery is inserted this safety
mechanism is released meaning that the alarm can
be attached to the backing plate.
4FitYour FireAngel Smoke Alarm
The alarm will only lock into place in one
particular position. Position the smoke alarm
over the mounting plate lining up the central vent
on the front of the alarm with the ‘X’ moulded
into the plastic on the mounting plate and turn

OPERATION
Normal condition
The red LED on the front should ash once every
40 seconds to show the alarm is active.
Low Battery Condition
IMPORTANT: Your smoke alarm
requires a battery with a sufcient
capacity of power to operate correctly, this
must also be correctly installed.
Should your FireAngel smoke alarm enter a low
battery condition, the unit will emit an audible
‘chirp’ once every 40 seconds. When this occurs
you must replace the battery immediately. Your
FireAngel smoke alarm will continue to warn of this
low battery condition for at least 7 days, however,
failure to change the battery after this time would
mean your smoke alarm has insufcient power to
alert you in a real re situation.
BATTERY REPLACEMENT
IMPORTANT: Only the following
batteries can be used for replacement.
Use of a battery other than those
recommended below may have a detrimental
effect on the detector’s operation. Use of
a lithium (long-life) battery could provide
power for 10 years under normal operating
conditions, meaning there is no need for an
annual battery change.
Carbon-Zinc type:
Eveready Energizer 1222; Gold Peak 1604S (UL).
Alkaline Type
Energizer 522; Duracell MN1604; Duracell 9V
Ultra; Energizer 9V Ultra+; Gold Peak 1604A.
Lithium (long life) type

ALARM SMART SILENCE™
DANGER: If your FireAngel smoke
alarm emits the full alarm signal and
you are not testing the unit, the smoke alarm
is warning you of a potentially dangerous
situation that requires your immediate
attention. Only use the alarm silence function
after making sure that there is no ongoing re
emergency situation. Do not block the vents
on the alarm or disable the smoke alarm in any
way, as this will remove your protection. In the
event of a known false alarm such as cooking
fumes your smoke alarm can be silenced in the
following way
Your smoke alarm features “Smart Silence™”
technology. Smoke alarms can sometimes react
to cooking fumes or other non emergency
situations. Should your alarm sound the central
test button can be used to temporarily silence
the alarm.Your alarm will automatically return to
full sensitivity within 10 minutes.

19
dYour alarm will automatically return to full
sensitivity on completion of the reset cycle
and the red LED will revert to ashing once
every 40 seconds.
DANGER: Never ignore any alarm.
Ignoring the alarm may result in injury
or death. If your smoke alarm activates and
alarms and you are not absolutely certain of
the source of the smoke, get everyone out of
the house immediately.
bYour alarm will silence and enter into
a reduced sensitivity reset cycle for
approximately 10 minutes.
cDuring the reduced sensitivity reset cycle, the
red LED on your alarm will ash more rapidly
than normal, approximately once every 10
seconds.
