INTRODUCTION
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 30 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

THERMOPTEK
TECHNOLOGY
Thermoptek alarms are “toast-proof”
meaning they can be positioned in areas
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.
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.

2. Install Base Plate
Fit the base plate to the ceiling or wall using
the screws provided.
3. Fit Your FireAngel Smoke Alarm
To fit to the smoke alarm to the base plate
included in this pack, position the alarm on
the base plate then twist it clockwise until
the alarm is locked in position. Make sure the
alarm is twisted on fully.
The battery will now activate. The red
indicator LED on the front of the alarm
should flash approximately once every
45 seconds to show that the alarm is active.
WARNING: Removing the smoke alarm
from its base plate will deactivate the unit
and prevent it from detecting smoke.
4. TestYour FireAngel smoke alarm
After fitting the alarm to the base plate, wait
for 5 seconds for the alarm to settle, then test
the alarm. See “AlarmTest”.
INTERLINKING YOUR
SMOKE ALARMS
The W2-Module in your ST-632 enables you
to wirelessly interlink with other alarms with a
W2-Module and create a Wi-Safe 2 network.
In order to communicate with each other,
W2-Module enabled alarms need to be “learned
in” or interlinked. If one alarm activates, all
other interlinked smoke alarms will also sound.
Note that Wi-Safe 2 smoke alarms can only be
interlinked with other Wi-Safe 2 smoke alarms
and other products within the Wi-Safe 2 range.
“Learning in” (interlinking) your Smoke
Alarms:
The process below describes ‘learning in’
two alarms into a network, “Alarm 1” and
“Alarm 2”.
1. Alarm 1: Install Alarm 1 as described
previously.
2. Alarm 2: Install the base plate for Alarm 2
in one of the recommended locations. Do
not t the second alarm to its base plate
yet.
3. Alarm 2: Using a pen, a paper clip that has
been opened out, briey push and release
the learn button located in a circular hole in
the back of Alarm 2.
Circular hole
The red LED next to the learn button will ash
briey then light up for approximately ve
seconds to show that it is ready to receive the
“learn in” signal. During these ve seconds
you will need to briey press the test button on
Alarm 1 to wirelessly interlink the two alarms.
Alarm 1 will give an audible sound consisting of
2 cycles of 3 loud beeps.
Alarm 2 The red LED on the wireless module
of Alarm 2 will ash to indicate that it has been
“learned-in” successfully.

4. TestYour FireAngel smoke alarm
After fitting the alarm to the base plate, wait
for 5 seconds for the alarm to settle, then test
the alarm. See “AlarmTest”.
INTERLINKING YOUR
SMOKE ALARMS
The W2-Module in your ST-632 enables you
to wirelessly interlink with other alarms with a
W2-Module and create a Wi-Safe 2 network.
In order to communicate with each other,
W2-Module enabled alarms need to be “learned
in” or interlinked. If one alarm activates, all
other interlinked smoke alarms will also sound.
Note that Wi-Safe 2 smoke alarms can only be
interlinked with other Wi-Safe 2 smoke alarms
and other products within the Wi-Safe 2 range.
“Learning in” (interlinking) your Smoke
Alarms:
The process below describes ‘learning in’
two alarms into a network, “Alarm 1” and
“Alarm 2”.
1. Alarm 1: Install Alarm 1 as described
previously.
2. Alarm 2: Install the base plate for Alarm 2
in one of the recommended locations. Do
not t the second alarm to its base plate
yet.
3. Alarm 2: Using a pen, a paper clip that has
been opened out, briey push and release
the learn button located in a circular hole in
the back of Alarm 2.
Circular hole
The red LED next to the learn button will ash
briey then light up for approximately ve
seconds to show that it is ready to receive the
“learn in” signal. During these ve seconds
you will need to briey press the test button on
Alarm 1 to wirelessly interlink the two alarms.
Alarm 1 will give an audible sound consisting of
2 cycles of 3 loud beeps.
Alarm 2 The red LED on the wireless module
of Alarm 2 will ash to indicate that it has been
“learned-in” successfully.
Note: If the test button is not pressed quickly
enough (before the red LED on the wireless
module of Alarm 2 has extinguished), the learn-
in process will fail. If this happens, repeat the
process again, as described above.
5. Fit Alarm 2 onto its base plate to
complete the installation.
6. Additional alarms should be “learned-in”
the same way. When learning in additional
alarms, any alarm already in the network,
can be used as ‘Alarm 1’. This means that
you can “learn-in” the additional alarm to
any alarm already in the network. It will
then become part of the whole network.
You do not have to “learn it in” to each
alarm in the network.
7. After completing the “learn-in” procedure,
test the alarms as described in “Alarm Test”.
If any interlinked alarm fails to respond to the
“Alarm Test”, remove it from its base plate and
repeat the learning in process.
Unlearning a Wi-Safe 2 Alarm
To remove an alarm from a network, push and
release, then push and hold the learn button.
When the red LED goes out, release the button.
Once the LED has ashed 5 times you have
successfully ‘Unlearned’ the alarm.
When removing an alarm from any Wi-Safe 2
network it is generally good practice to “unlearn”
every alarm (in the same way as mentioned
above) and rebuild the network once again by
following the “learn-in” process on page 6.
Please note: It is important not to rush the
Wi-Safe 2 system and is also good practice
to allow several minutes after un-learning the
system before rebuilding the network once again.

LOW BATTERY CONDITION
IMPORTANT: Your smoke alarm requires
that its battery has sufficient power capacity
to operate correctly.
Should your FireAngel smoke alarm enter a
low battery condition, the unit will emit an
audible ‘chirp’ once every 45 seconds and
the amber LED will flash at around the same
time. All other alarms in the network will also
emit an audible low battery chirp once every
4 hours.
When this occurs, we recommend you
replace the alarm immediately. Your smoke
alarm will continue to warn of this low
battery condition for at least 30 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 battery will
automatically deactivate and the low power
warning chirp should stop, allowing you to
dispose of the alarm.

OPERATION
NORMAL CONDITION
The alarm will check its sounder once a
month. If the alarm is interlinked with a
FireAngel Wireless Gateway unit via a Wi-
Safe 2 network, it will report the alarm status
into the Wireless Gateway.
During normal operation, the LED does not
flash and the audible alarm signal does not
sound.
NOTE: The alarm checks the sounder every
30 days. During this time the unit may emit
an unobtrusive clicking noise. This does not
resemble the alarm signal or fault signal and
will be difficult to detect during everyday
activity.
ALARM CONDITION
If the alarm goes into alarm, 3 loud beeps
will sound, which continually repeat until the
cause of the alarm being activated is found
and resolved. The red LED on the alarm will
flash rapidly (once per second) during these
alarms. All interlinked alarms will sound the
same pattern.
FAULT INDICATION
If the yellow LED flashes and an short
audible beep is heard at a different time, this
indicates that there is a fault; the unit may
not detect smoke and may not sound an
alarm in the event of a fire. If this occurs, it is
strongly recommended that you replace the
alarm immediately.

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

11
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.
1. Briefly press and release the pause button,
the alarm sound will shortly stop.
2. Your alarm will silence and enter into
a reduced sensitivity reset cycle for
approximately 10 minutes.
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 month.
If your ST-632 is interlinked with other smoke
alarms, we recommend that every individual
smoke alarm is tested during the monthly test.
a) Briey press the test button in the centre
of the smoke alarm and release.
b) The unit you are testing will give an
audible alarm consisting of 2 cycles of
3 loud beeps, then stop automatically.
The red LED on this alarm will ash rapidly
(once per second) during the audible
alarm. All interlinked alarms will give an
audible alarm consisting of 2 cycles
of 3 loud beeps, then stop automatically,
indicating the test is complete. The red
LED on all interlinked alarms will not ash
rapidly. If any alarm fails to self-test, see
Troubleshooting..

the red LED on your alarm will continue
to flash more rapidly than normal,
approximately once every 10 seconds.

and the red LED will revert to flashing
once every 45 seconds.

you replace your alarm immediately, and
certainly within 30 days, as your alarm may
then have insufficient power to warn you of
a real fire situation after this time.
WARNING: Your smoke alarm cannot be
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.
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.
If your ST-632 is interlinked with other alarms,
pressing the test button will also silence other
alarms in the network. However, any alarm
that has sensed smoke (an instigating alarm)
cannot be remotely silenced. This means that
any alarm that has sensed smoke will continue
to sound allowing you to locate it.
If any instigating alarm in the network has not
been silenced after a short period (2-4 minutes),
all other alarms will start sounding again to alert
you.
WARNING: If any alarm in the network is
sounding, it is warning you of a potentially
hazardous situation. Do not ignore it.
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 battery warning
silence. However it is recommended that

emits a brief beep
intermittently.
• Check the location of your smoke alarm (see "Application" and
"Positioning").
• Check that your smoke alarm is denitely the source of the beeping; ensure
the noise isn’t coming from another alarm (smoke/carbon monoxide/gas/
burglar alarm) by process of elimination.
• If the brief beep is emitted once every 45 seconds, and the yellow LED is
ashing around the same time, this indicates that the battery is low. The
unit should be replaced within 7 days.
• If your smoke alarm is chirping once every 4 hours, it is indicating that
another alarm in the network has entered a low battery condition. Locate
the alarm with the low battery condition and replace the alarm as soon as
possible and in any event within 30 days.
