THERMOPTEK
TECHNOLOGY
Thermoptek alarms are “toast-proof”
meaning they can be positioned in area
close to kitchens that may be affected by
cooking fumes Heat alarms should be
used in kitchens where required
This combines an optical sensing chamber
with thermal enhancement The alarm is
effective at detecting slow burning fires,
and 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
POSITIONING
WARNING: Your 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
INTRODUCTION
The ST-750 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 In
addition, this smoke alarm allows the
low battery warning chirp to be silenced
until it is convenient to replace the alarm
(recommended within no more than 7
days)
IMPORTANT: This user manual contains
important information regarding the
operation of your 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 with
the end user
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 on this
alarm is automatically enabled when the
alarm is fully locked on to the base plate

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
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 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 regulatory requirements
for common areas such as lobbies and
hallways
Smoke alarms should be sited at least
300mm from light fittings and walls
Ideally as central as possible in the room
If positioning your smoke alarm on the
wall, the top of the detection element must
be between 150mm and 300mm below the
ceiling, and at least 300mm from a wall
Smoke alarms should be positioned at no
more than 600mm vertically below the
highest point in the room

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 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

low power warning chirp should stop,
allowing you to dispose of the alarm
Low Battery Warning Silence
This feature can temporarily silence a
low battery chirp for 8 hours which is
particularly useful if a warning begins
during the night This feature may be
repeated up to 10 times, but is not a
substitute for replacing the smoke alarm
ALARM TEST
The alarm must be properly attached to
the base plate before it can be tested
a Press the test button in the centre and
release
Once the smoke alarm has been fitted
onto the base plate correctly, the internal
power pack will activate The red LED on
the front of the alarm should now flash
once every 40 seconds to show that it is
active
4 Test Your Smoke Alarm

wait for 5 seconds for the alarm to settle
then test the alarm See ‘Alarm Test’
OPERATION
Normal Condition
The red LED on the front should flash
every 40 seconds to show that the alarm
is active
Low Power Pack Condition
IMPORTANT: Your smoke alarm requires
the power pack to have sufficient capacity
of power to operate correctly
Should your smoke alarm enter a low
power pack condition, the unit will emit
an audible ‘chirp’ once every 40 seconds
When this occurs, we recommend you
replace the alarm immediately Your
smoke alarm will continue to warn of this
low power pack condition for at least 7
days, however, failure to change the alarm
after this time would mean your smoke
alarm may have insufficient power to alert
you in a real fire situation When the alarm
is removed from the base plate the power
pack will automatically deactivate and the
9
b The unit will give an audible alarm
consisting of 2 cycles of 3 loud beeps,
then stop automatically
c The red LED on your alarm will flash
rapidly during the audible signal
NOTE: The test button accurately tests
the alarm’s smoke sensing circuit, there is
no need to test your alarm with smoke If
your smoke alarm fails to give an audible
test signal, please refer immediately to the
trouble shooting guide at the end of this
manual
WARNING: You should test your smoke
alarm every week
ALARM SMART
SILENCE™
DANGER: If your 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 fire
emergency situation Do not block the
vents on the alarm or disable the smoke
alarm in any way, as this will remove your
protection Smoke alarms can sometimes
react to cooking fumes or other non
emergency situations Your smoke alarm
features “Smart Silence” technology In
the event of a known false alarm your
smoke alarm can be temporarily silenced
by pressing the central test button Your
alarm will automatically return to full
sensitivity within 10 minutes
NOTE: If the level of smoke reaching the
alarm is very high the alarm silence will be
overridden and the alarm will continue to
sound
a Press and release the silence button, the
alarm sound will shortly stop
10
b Your alarm will silence and enter into
a reduced sensitivity reset cycle for
approximately 10 minutes
c During the reduced sensitivity reset
cycle, the red LED on your alarm will
continue to flash more rapidly than
normal, approximately once every
second
d Your alarm will automatically return
to full sensitivity on completion of the
reset cycle and the red LED will revert to
flashing 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
SLEEP EASY™
Low battery warnings often start at night
or when it maybe inconvenient to replace
your alarm You can silence the audible
chirp for a period of 8 hours by pressing
the test button Your smoke alarm will
still detect smoke during this time of low
11
battery warning silence However it is
recommended that you replace your alarm
immediately, and certainly within 7 days,
as your alarm may then have insufficient
power to warn you of a real fire situation
after this time

silenced if the chirp is indicating a fault In
this instance, the unit should be replaced
immediately to ensure protection in the
event of a fire
