INTRODUCTION
Congratulations! You’ve made a wise
investment in protecting your family and
home. The FireAngel WST-630 wireless
interlink multi-criteria high performance
detector is the ultimate alternative to
traditional alarms. Ground breaking
Thermoptek™ technology combines the
very latest in optical sensing with thermal
enhancement, providing fast response to
both fast aming and smouldering res ,
eliminating the need for ionisation sources
which can be harmful to the environment.
Up to a maximum of fty WST-630 alarms can
be wirelessly interlinked, creating a network.
If any smoke alarm sounds, it triggers
all other alarms in its network to sound
simultaneously. This provides the earliest
possible warning of a re.
Alarm signals are passed between all
WST-630’s in the network, increasing the
network range and reliability.
The FireAngel range of products is constantly
being improved and expanded. Please visit
our website www.reangel.co.uk to nd
out about the latest additions to our range
and in particular our new range of wireless
Wi-Safe 2 products.
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
Traditionally 3 types of sensor technology
have been used in domestic self-contained
re alarms. Optical smoke alarms are typically
more e󱐯ective at detecting slow burning
res, which can smoulder for hours before
bursting into ames. Ionisation smoke alarms
are generally more e󱐯ective at detecting fast,
aming res which consume combustible
materials rapidly and spread re 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 suitable, such as
kitchens.
AUTOMATIC POWER
ENGAGE
Your 10 year life smoke alarm is powered
by an internal lithium power pack which is
supplied in a deactivated state. The power
pack is automatically enabled when the
alarm is fully locked on to the mounting plate
and disabled when removed.
IMPORTANT: Your alarm will not work
until it is correctly located and secured
onto the mounting plate

THERMOPTEK™SENSOR
TECHNOLOGY
The state of the art thermally-enhanced
optical sensing chamber provides a fast
reaction to both slow smouldering and
fast aming res in a single alarm. The
Thermoptek™ technology constantly
monitors temperature changes and if a rate
of temperature rise is detected the sensitivity
of the alarm is increased meaning it has a fast
response time to fast aming res as well as
slow smouldering res.
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 o󱐰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

PROTECTION
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 re station for further guidance.
The FireAngel WST-630 is designed to be
wirelessly interlinked with other WST-630
smoke alarms. The WST-630 is not designed
to communicate with wireless smoke alarms
from other ranges or manufacturers.

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 tted 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.
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
WST-630 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 the
WST-630 smoke alarm in common areas
may not provide su󱐰cient re warning to
residents or meet regulatory requirements.
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.

• 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.
WARNING: Prolonged exposure to
temperatures outside those stated
above will reduce product life.
IMPORTANT: Obstructions such as
steel reinforcement in concrete could
block or impede the wireless signal. While
the wireless range is over 200 metres in
clear air / clear line of sight, the e󱐯 ective
range may be reduced by wall and other
obstructions in the building. Always
ensure that after any building work or after
repositioning large items of furniture (beds,
sofas, shelving units etc.), you carry out an
alarm test on all networked smoke alarms
to ensure they are all still working. It is
recommended not to exceed 35m as the
maximum distance between smoke alarms
in the network.
Note: Up to  fty WST-630 smoke alarms
and/or Wi-Safe 2 accessories can be learned
in to a single network.

occurs you are strongly recommended to
replace the unit within 7 days.
IMPORTANT: Smoke alarms are
designed to alert you with an audible
alarm at a level specied 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, tra󱐰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 WST-630 Smoke alarm
is not suitable for alerting hard of hearing
or deaf residents. It may be interlinked with
a product from the FireAngel Wi-Safe 2
range which is designed specically for the
hard of hearing. See www.reangel.co.uk
for specially designed warning systems
for the hard of hearing or deaf such as a
vibrating pillow pad or ashing strobe. We
recommend that where required, warning
systems be installed that will alert hard of
hearing or deaf 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,
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 su󱐰cient time or quantity
to sense and alert you to the danger. We
recommend that as a minimum you install
Thermoptek™ 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 di󱐯erent 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 su󱐰cient power. As the
alarm’s power pack reaches the end of its life
a low power warning chirp will be emitted
approximately every 45 seconds. When this

7
as with any electronic product it may fail
and may not sense all types of re within
su󱐰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, 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 INSTALL YOUR
SMOKE ALARM
IMPORTANT: Make sure you have read
and understood this manual before
installing your smoke alarm.
1. Preparation
The mounting plate should be attached to
the ceiling or wall.
Break out the tabs from the mounting
plate. 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 required).
2. Install Mounting Plate
Fit the mounting plate to the ceiling or
wall using the screws provided.
Mounting plate tabs

3. Fit Your FireAngel Smoke Alarm
To t to the mounting plate included
in this pack, position the alarm on the
mounting plate then twist it clockwise
until the alarm is locked in position. Make
sure the alarm is twisted on fully.
The power pack will now activate. The red
LED (visual indicator) on the front of the
alarm should ash approximately once every
45 seconds to show that it is active.
WARNING: Removing the smoke alarm
from its mounting plate will de-activate
the unit and prevent it from detecting smoke.
4. Test Your FireAngel Smoke Alarm
After tting the alarm to the mounting
plate, wait for 5 seconds for the alarm to
settle then test the alarm. See ‘Alarm Test’
on page 12.
INTERLINKING YOUR
WST-630 SMOKE ALARMS
This smoke alarm contains an inbuilt RF
module, and enables you to wirelessly
interlink two or more smoke alarms and
create a network. Therefore WST-630 alarms
need to be “learned in” or interlinked in
order to communicate with each other. If
one alarm activates, all other interlinked
smoke alarms will also sound. Note that
WST-630s can only be interlinked with other
WST-630s and products within the FireAngel
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 on page 7.
2. Alarm 2
Install the mounting plate for Alarm 2
in one of the recommended locations (see
Positioning on page 4) Do not t the
second alarm to its mounting plate yet.
3. Alarm 2
Using a pen, a very small screwdriver or
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.

9
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 the next 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.
Circular hole
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 mounting 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 into
any alarm already in the network. It will
then become part of the whole network.
You do not have to “learn it in” into 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 mounting
plate and repeat the learning in process.

10
OPERATION
Normal Condition
The red LED on the front will ash
approximately every 45 seconds to show that
the alarm is active.
Low Power Pack Condition
IMPORTANT: Your smoke alarm requires
the power pack to have su󱐰cient
capacity of power to operate correctly.
Should your FireAngel smoke alarm enter a
low power pack condition, the unit will emit
an audible ‘chirp’ approximately once every
45 seconds and the amber LED will ash at
around the same time. When this occurs it
is strongly recommended you replace the
alarm immediately and in any event within
30 days.
Your FireAngel smoke alarm will continue to
warn of this low power pack condition for at
least 30 days. However, failure to change the
alarm after this time would mean your smoke
alarm may have insu󱐰cient power to alert
you in a real re situation. When the alarm is
removed from the mounting plate the power
pack will automatically deactivate and the
low power warning chirp will stop, allowing
you to dispose of the alarm.
IMPORTANT: If your WST-630 smoke
alarm enters a low power pack
condition, it will emit an audible “chirp”
approximately once every 45 seconds. All
other WST-630 alarms in the network will also
emit an audible low battery chirp once every
4 hours. This will continue until the smoke
alarm which has the low battery condition is
removed.
Fault Indication
If the amber LED ashes and an audible ‘chirp’
is heard at a di󱐯erent time, this indicates that
there is a fault; the unit may not detect smoke
and may not go into alarm in the event of a
re. If this occurs it is strongly recommended
that you replace the alarm immediately.
Alarm condition
If the WST-630 goes into alarm, all interlinked
alarms will also sound 3 loud beeps which
continually repeat until the cause of the
alarm being activated is found and resolved.
The red LED will only ash rapidly (once per
second) on alarms that have responded
directly to smoke.

to give an audible test signal, please refer
immediately to the trouble shooting guide at
the end of this manual.
WARNING: As with all electronic alarm
products you should test your smoke
alarm every week.
If your WST-630 is interlinked with other
smoke alarms, we recommend that every
individual smoke alarm is tested during the
weekly 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 on page 16.
ALARM TEST
a) Briey press the test button in the centre
and release.
b) The unit will give an audible alarm
consisting of 2 cycles of 3 loud beeps,
then stop automatically.
c) The red LED on the alarm will ash rapidly
during the audible signal.
NOTE: The test button tests the alarm’s smoke
sensing circuit. There is no need to test your
alarm with smoke. If your smoke alarm fails
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 re. Do not block the vents

13
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 briey 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. Briey press and release the test button.
The alarm sound will soon stop.
2. Your alarm will silence and enter into a
reduced sensitivity mode for
approximately 10 minutes.
3. During the reduced sensitivity mode the
red LED on your alarm will continue to ash
more rapidly than normal, approximately
once every 10 seconds.
4. Your alarm will automatically return to full
sensitivity after a maximum of 10 minutes
and the red LED will revert to ashing
once every approximately 45 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.
If your WST-630 is interlinked with other
alarms, pressing the test button will
also silence other alarms in the network.
However, any alarm that has sensed smoke

14
ROUTINE MAINTENANCE
Your FireAngel smoke alarm has been
designed to be as maintenance-free as
possible, however there are several things
you must do to keep it working properly.
CAUTION: Your FireAngel smoke alarm
is a sealed electrical device and no
attempt should be made to open the case.
Attempting to open the case will invalidate
your Warranty.
WARNING: This device contains a
powerful lithium battery. If tampered
with , the battery may be shorted and create
a re hazard. Never attempt to open or
damage the battery.
Testing
Test your smoke alarm once every week, see
section ‘Alarm Test’ on page 12. Any test
failures should be reported to the FireAngel
Technical Support Team see page 18.
Cleaning
As a minimum your smoke alarm should be
cleaned once every 3 months using your
vacuum cleaner tted with the soft brush
attachment.
WARNING: Your FireAngel smoke alarm
may false alarm when it is being cleaned
using a vacuum cleaner.
IMPORTANT: Do not use solvents or
cleaners on your FireAngel smoke alarm,
as they may cause damage to the sensor
or circuitry. The unit can be wiped with a
slightly damp cloth.
CAUTION: Do not paint the smoke alarm
as this may block the openings and
prevent smoke from entering the sensor.
(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.
WHAT TO DO IN CASE OF
A FIRE IN YOUR HOME
• If you have made a family escape plan
and practiced it with your family, you
have increased their chances of escaping

15
REPAIR
DO NOT attempt to repair your FireAngel
smoke alarm as doing so will invalidate
your warranty. If your smoke alarm is not
operating properly, see the next section
‘Troubleshooting’. If you cannot solve the
problem, please call the FireAngel Technical
Support Line see page 18. If your FireAngel
smoke alarm is no longer under warranty,
replace immediately with a comparable
FireAngel brand smoke alarm.
WARNING: This device contains a lithium
battery. If tampered with, the battery
may be short circuited and create a re risk.
Never attempt to open or damage the alarm.
Always avoid dropping, or damaging the
alarm, or short-circuiting the power pack. As
with any electrical device which has its own
power supply the alarm should be treated
with respect and in accordance with the
manufacturer’s guidance particularly after it
has been uninstalled.
If your smoke alarm is dropped or damaged,
as a precaution, it should be removed
from the building and you should contact
FireAngel Technical Support on 0800 141
2561 or technicalsupport@reangel.co.uk
safely. Go over the following rules with your
children each time you have re drills. This
will help everyone remember them in case
of a real emergency.
• Don’t panic, stay calm. Your safe escape
may depend on thinking clearly and
remembering what you have practiced.
• Notify every member in the household.
• Get out of the house as quickly as possible.
Follow a planned escape route. Do not stop
to collect anything or to get dressed.
• Feel the doors with the back of your hand.
If they are hot, do not open them – use an
alternative escape route.
• Stay close to the oor. Smoke and hot
gases rise.
• Cover your nose and mouth with a cloth
(wet if possible). Take short, shallow
breaths.
• Keep doors and windows closed. Open
them only if you have to in order to escape.
• Meet at your planned meeting place after
leaving the house. Carry out a head count.
• Call the Fire and Rescue service on 999 as
soon as possible from outside your house. If
possible use a neighbours phone or call box
rather than a mobile phone (as the location
can be traced from the number if the line is
lost, or the battery runs out for example).
• Give the address and your name.
• Never go back inside the building until a
member of the re service has told you it is
safe to do so.

16
TROUBLESHOOTING
Problem Solution
Your FireAngel smoke alarm
does not sound during
testing
• Make sure the alarm has been rotated clockwise as far as
it can go and is securely located on its mounting plate.
• If testing immediately after rst activating the alarm, you
should allow a few seconds for the alarm to settle before
testing.
• Make sure you push the centre of the test button rmly.
• If the unit has been silenced and is in low sensitivity mode
it may not test. Wait 15minutes then try again.
• If the alarm has been recently tted and it still fails to self
test then contact technical support (see page 18).
• Check positioning. The wireless signal might be blocked
or out of range.

Problem Solution
Your FireAngel smoke alarm
chirps intermittently
• Check the location of your smoke alarm (see ‘Application
& Positioning’)
• Check that your smoke alarm is denitely the source of
chirping; make sure the noise isn’t coming from another
alarm (smoke/carbon monoxide/burglar/gas alarm) by
process of elimination.
• If the alarm is chirping once approximately every 45
seconds and the amber led is ashing around the same
time, it indicates that the power pack is low. The unit
should be replaced within 30 days.
• If your smoke alarm is chirping once every 4 hours, it is
indicating that another alarm in the network has entered
a low power pack condition. Locate the alarm with the
low battery condition and replace the alarm as soon as
possible and in any event within 30 days.
Your FireAngel smoke alarm
activates when no smoke is
visible
• Check the location of your smoke alarm (see the section
on ‘Positioning’)
• Clean the smoke alarm (see the section on ‘Routine
Maintenance’)
• If the alarm is sounding but the red LED is only ashing
approximately once every 45 seconds, this indicates that
an inter-linked alarm has detected smoke. Vacate
property if there is a re hazard.

Problem Solution
Other interlinked units fail
to silence when one unit is
silenced
• Interlinked units that have sensed smoke can’t be
silenced. If one or more unit remains in alarm, all other
interlinked units will emit their audible warning again
within 4 minutes. Vacate property if there is a re hazard.
You experience frequent
unwanted alarms
Check the location of your FireAngel smoke alarm (see the
section on ‘Positioning’)
• Clean the smoke alarm (see the section on ‘Routine
Maintenance’)
• Any activated alarm will cause other interlinked alarms
to sound. Carry out these checks on the activated alarms
in particular (red LED ashing rapidly during alarm).
• If the frequent unwanted alarms continue contact
technical support for advice
The yellow LED is ashing
and the alarm is making a
“chirping” sound
• If the yellow LED is ashing at around the same time as
the chirp, this indicates a low power pack condition and
the alarm should be replaced as soon as possible and
certainly within 30 days.
• If the yellow LED is ashing at a di󱐯erent time to the
chirp, this indicates a fault and the alarm should be
replaced as soon as possible.
• If the yellow LED is double ashing and the alarm is
making a “chirping” sound, this indicates that the wireless
module has a low power pack condition, or is faulty. The
alarm should be replaced as soon as possible.
If the alarm fails to operate
correctly, the advice of the
manufacturer should be
sought
