AUTOMATIC POWER
ENGAGE
Your 10 year life smoke alarm is powered
by an internal lithium power pack. To avoid
unnecessary use of the power pack prior to
installation, and to ease disposal when the
alarm reaches the end of its life, the alarm is
supplied with the power pack in a deactivated
state. The power pack is automatically
enabled when the alarm is fully locked on to
the mounting plate.
WARNING: This automatic power
engage system only applies to the
following 10 year smoke alarms:
ST-620
IMPORTANT: Your alarm will not work
until it is correctly located and secured
on the mounting plate.
INTRODUCTION
Congratulations! You’ve made a wise
investment in protecting your family and home.
The ST-620 multi-criteria high performance
detector is the ultimate alternative to traditional
alarms. Groundbreaking Thermoptek
technology combines the very latest in
optical sensing with thermal enhancement,
providing faster response to both fire types
eliminating the need for ionisation sources
which can be harmful to the environment.
The FireAngel range of products is constantly
being improved and expanded. Please visit
www.fireangel.co.uk to find out about the
latest additions to our range of innovative
products.
IMPORTANT: This user manual
containsimportant 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
Traditionally 3 types of senor technology have
been used in domestic self contained fire
alarms.
Optical smoke alarms are typically more
effective at detecting slow burning fires,
which can smoulder for hours before bursting
into flames.
Ionisation smoke alarms are generally more
effective at detecting fast, flaming fires which
consume combustible materials rapidly and
spread fire quickly.
Heat alarms are triggered when room
temperature reaches a set point (typically
56°C) these alarms are generally used in
locations where other alarm types are not
suited.
THERMOPTEK SENSOR TECHNOLOGY
Thermoptek technology combines a state of
the art optical sensing chamber with thermal
enhancement so not only is the alarm effective
at detecting slow burning fires, constant
monitoring of temperature changes enables the
sensitivity of the alarm to be instantly increased
thereby quickening the typical response time
to fast flaming fires significantly.
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 fire service or
building control department at your local
council offices. 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 floor/level of your
property.
In order to achieve the earliest fire warning,
we recommend that a smoke alarm is fitted in
all rooms where the temperature is normally
between 4°C (40°F) and 38°C (100°F).
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 below 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 fire station for further guidance.
Multi-family or mixed occupant residence
(Tenancy building, student accommodation)
Your FireAngel smoke alarm can also be used
in individual flats and bedsits, providing the
same conditions are met as for a single-family
residence. However, there must already be
a primary fire detection system that meets

MINIMUM RECOMMENDATIONS
EXISTING HOMES
NOTE: Kitchens should be covered by a

RECOMMENDED FOR ADDITIONAL
PROTECTION
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 fire 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 sufficient fire warning to residents
or meet regulatory requirements. This smoke
alarm is designed to operate as a standalone
smoke alarm.
WARNING: This FireAngel smoke
alarm will not communicate with other
smoke alarms or fire 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.

POSITIONING
Thermoptek smoke alarms are less prone
to false alarms from cooking fumes, and
are therefore suitable for locations near
kitchens. However like other types of smoke
alarms, thermoptek smoke alarms can be
susceptible to nuisance alarms from steam
and should not be located too close to
bathrooms and showers.
It is recommended that your FireAngel
smoke alarm is NOT to be fitted in the
following locations:
• Bathrooms, shower-rooms, and other very
damp or humid areas, where the moisture
can cause unwanted alarms.
• Kitchens. Kitchen areas 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
fitting 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.
WARNING: Prolonged exposure to
temperatures outside those stated above
will reduce product life.

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 fire 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
sufficient time or quantity to sense and alert
you to the danger.
We recommend that as a minimum you install
Thermoptek smoke alarms on every floor of
your property. For comprehensive coverage
a smoke alarm should also be fitted in every
room.
This smoke alarm cannot be used to provide
primary fire detection in common areas used
by different residents such as blocks of flats
and hotels. The FireAngel smoke alarm may
not alarm before a fire 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
fire.

WARNING: Your smoke alarm will not
operate without sufficient power.
As the alarm’s power pack reaches the end
of its life a low power warning chirp will be
emitted every 45 seconds. When this occurs
you must replace the unit within 7 days.
IMPORTANT: Smoke alarms are
designed to alert you with an audible
alarm at a level specified by the European
Standard 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, traffic and other loud
sources may also prevent the alarm being
heard. Heavy sleepers and residents under
the influence 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
European Standards. However, as with any
electronic product it may fail and may not
sense all types of fire within sufficient time to
alert you of the danger and provide adequate
timefor your escape. In orderto 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,
flames, or gas. It will not prevent or extinguish
fires.
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.
