INTRODUCTION
IMPORTANT: If you are installing this product for
use by others, you must leave this manual (or a copy
of it) for the end user.
Wi-Safe 2®is the very latest in wireless technology
from Sprue Safety Products. It provides a network
of wireless radio frequency (RF) communication
which can trigger Wi-Safe 2®Alert products to alarm
simultaneously in the event of danger.
This Low Frequency Sounder, when interlinked with
Wi-Safe 2®enabled Smoke alarms and/or Wi-Safe 2®
enabled Carbon Monoxide (CO) Alarms (purchased
separately) will provide warning of danger from
smoke and/or carbon monoxide for people who may
respond to a lower frequency audible sound.
The Low Frequency Sounder has been specifically
designed to provide additional protection to standard
smoke alarms in the event of a fire.
A low frequency signal is more likely to wake up high
risk individuals such as children, those with mild to
moderate hearing loss, older people and people
under the influence of alcohol than a regular smoke
alarm, according to research*
*Bruck, D. & Thomas, I (2007) Waking effectiveness of alarms
(auditory, visual and tactile) for adults who are hard of hearing.
Optimizing Fire Alarm Notification for High Risk Groups Research
Project. pp.66.
KEY FEATURES
• Uses Wi-Safe 2®technology to provide warning of
fire or Carbon Monoxide (CO). Wi-Safe 2®products
can be interlinked to create a network, meaning
if smoke or CO triggers any alarm in the network,
all other networked alarms and ancillary devices
activate.

3
• When used with Wi-Safe 2®enabled Smoke and/or
CO alarms, the Low Frequency Sounder provides
additional protection when a standard high pitched
sound alone may not be enough.
• Provides a simple two button press “learn in”
process to wirelessly interlink with Wi-Safe 2®
smoke alarms or CO alarms
• The Low Frequency Sounder provides a remote
low level testing facility for testing interlinked
smoke and CO alarms, avoiding the need to reach
up to ceiling mounted alarms to test.
• Mains powered with rechargeable battery back-up
(must be replaced after 5 years).
• The Low Frequency Sounder will detect and
demonstrate a fault or low battery warning with
any smoke alarm or CO alarm within the inter-
linked network.
• The Low Frequency Sounder is suitable for wall
mounting with 2 screw fixings or free standing.
• Designed for use with Smoke alarms and Carbon
Monoxide alarms from the Wi-Safe 2®range
(purchased separately).

INSTALLING THE LOW
FREQUENCY SOUNDER
PREPARATION: Please ensure you have read and
understood this entire manual before installing your
Low Frequency Sounder.
Your Low Frequency Sounder is designed to be used
in conjunction with Smoke alarm(s) and CO alarm(s)
from the Wi-Safe 2®range of products.
It is recommended that for optimum protection
from smoke and/or carbon monoxide, one Wi-Safe
2®smoke alarm is fitted in each living room of your
home, including bedrooms, and one Wi-Safe 2®CO
alarm is fitted in every room containing a fossil fuel
appliance, with your Low Frequency Sounder.
NOTE: Up to fifty Wi-Safe 2®enabled
Smoke alarms, CO alarms and/or Wi-Safe 2®
accessories can be interlinked (“learned in”)
to a single network.
Ensure all smoke alarms and/or CO alarms to be
used are installed, tested and working correctly as
fig1
per the instructions in their respective user manuals.
CONNECTING THE
BATTERY/MAINS POWER
NOTE: The Low Frequency Sounder requires both a
continuously powered AC (mains) electrical supply
and internal battery for its normal operation. The
battery accompanying this product is rechargeable
and charges when there is mains power to the Low
Frequency Sounder.
1. Remove the battery cover on the back of the Low
Frequency Sounder by pressing the tabs on either
side of the battery cover as shown (fig 1).

5
2. Connect the rechargeable battery, by aligning the
terminals (red wire to red wire) and clipping the
connectors together.
CAUTION: Connect the battery with mains
power disconnected.
3. Place the battery into the recess. NOTE:The
battery cable needs to be positioned underneath
the battery. Place the cable into the bottom of the
recess and place the battery over the top, with the
battery text facing up as shown (fig 2). This will
ensure that the battery is installed correctly.
4. Assemble the power cable and adaptor by
positioning the plug head as shown. Rotate onto
the adaptor clockwise until it clicks into position.
fig3
5. Plug the power cable in to the Low Frequency
Sounder by fitting the cable into the connection
point as shown (fig 4).
fig2 fig4

6. Replace battery cover.
7. Plug in the mains adaptor and turn the power
on.The green power LED should illuminate.
Within a few seconds, the amber fault LED will be
continuously illuminated; both alarm LEDs (smoke
and CO) should be extinguished.
NOTE: When power is first provided to the Low
Frequency Sounder, the amber fault LED and both
red alarm LEDs will flash twice; the amber LED will
then illuminate continuously to indicate that the unit
has not been “learned in” to any network. This will
typically happen when the battery is connected. If the
has not retained any residual charge during shipping,
it will happen when the mains power is connected.
You will also see a low battery warning indication
as the amber fault LED will flash once every five
seconds.
WIRELESSLY INTERLINKING
THE LOW FREQUENCY
SOUNDER TOYOUR
WI-SAFE 2®SMOKE OR
CO ALARM
It is recommended that you read through
these “learn in” instructions before starting.
Learning a Low Frequency Sounder into a new
Wi-Safe 2®system:
1. Place one of your Smoke or CO alarms on to its
baseplate.You will use this product to interlink
with the Low Frequency Sounder to create a
network.
2. Briefly push and release the learn button located
in a circular hole in the back of the Low Frequency
Sounder using a pen, or similar as shown
(fig 5).

7
3. After pressing this button, the two Alarm (red)
LEDs on the front of the unit will flash and then
illuminate for 5 seconds.
4. During this period, while the red LEDs are
illuminated, press the test/reset button on the
Smoke or CO alarm to wirelessly interlink the two
products.The Smoke alarm (or CO alarm) will emit
an audible signal, and the red (Alarm) LED on the
Smoke (or CO alarm) will also flash.
5. After learning in the Low Frequency Sounder into
the alarms, test the units separately to ensure they
are wirelessly interlinked (see below) and test
again in final installed position.
Learning a Low Frequency Sounder into an
existing Wi-Safe 2®system:
1. Locate a Smoke / CO alarm that is already part of
the existing Wi-Safe 2® system.You will use this
product when adding the Low Frequency Sounder
into the network.
2. Follow steps from point 2 above.To add any
further alarms to the network, press the learn
button on the new alarm then the test button on
the Low Frequency Sounder, or on any alarm
already learned in to the network.
NOTE: The battery is supplied in a discharged or
partially discharged state and will require up to 72
hours of charging (continuous connection to the
mains supply) to ensure that it is fully charged. During
this period the amber fault LED may flash once every
five seconds to indicate that the battery is low. The
following tests however may be carried out before
the charging is complete.
Further Wi-Safe 2®products (including additional
fig5

8
Low Frequency Sounders) can be learned into the
network in the same way. The learn button on the
Low Frequency Sounder is located on the back of the
product.
After learning in the Low Frequency Sounder into the
alarms, test the units separately to ensure they are
wirelessly interlinked (see below).
TO REMOVE THE
LOW FREQUENCY SOUNDER
FROM THE WIRELESS
NETWORK
IMPORTANT: If you need to remove (“unlearn”) the
Low Frequency Sounder from the wireless network,
eg for house alterations, or to dispose of the unit
it is important to follow the instructions below to
“unlearn” the unit from the wireless network. Failure
to do so means that the network continues to try and
communicate with the removed unit, and will result
in a system fault.
1. Briefly push and release the learn button located
in the circular hole in the back of the Low
Frequency Sounder using a ball point pen or
similar as shown (fig 5). The two red alarm LEDs
on the front of the Low Frequency Sounder will
illuminate as you push the button.
2. Push and hold the learn button a second time.
The red alarm LEDs will illuminate. Hold the
button until the red alarm LEDs extinguish.
3. The red alarm LEDs will then perform a sequence
of two long and three short flashes. The amber
fault LED will illuminate to confirm that the Low
Frequency Sounder is no longer interlinked to the
wireless network.
4. Press the test button on the Low Frequency
Sounder. It should not cause other Wi-Safe 2®
alarms to sound. However, if the Low Frequency
Sounder is still interlinked, repeat the above
procedure.

9
TESTING THE LOW
FREQUENCY SOUNDER WITH
YOUR WI-SAFE 2®SMOKE/CO
ALARMS
Testing the network from the Smoke Alarm or
CO alarm
Briefly press the test button on the smoke alarm or
CO alarm and release (fig 6). The alarm will give an
audible sound (consisting of 2 cycles of 3 loud beeps
on the smoke alarms, 2 cycles of 4 rapid beeps on
CO alarms), then stop automatically. The red alarm
LED on the alarm will flash rapidly during the audible
signal. Any other wirelessly interlinked alarms which
are also part of the network will also give an audible
alarm then stop automatically.
The Low Frequency Sounder will sound the
same pattern as the alarm being tested and the
corresponding alarm LED (smoke or CO) will flash
during the test.
Repeat the procedure with all alarms in the wireless
network.
Testing the network from the Low Frequency
Sounder
Briefly press the test button on the Low Frequency
Sounder and release. The Low Frequency Sounder
will sound a pattern of 2 cycles of 3 loud beeps and
both alarm LEDs (smoke and CO) will flash. At the
same time any alarm that is wirelessly interlinked
(learned in) to the network will also sound, the
sound pattern on each alarm corresponding to its
type (smoke or CO – see previous section). The Low
Frequency Sounder will be activated for the length of
time that the alarms sound (2 cycles of 3 beeps).
fig6

10
This confirms that the units are wirelessly interlinked.
Weekly Testing
It is recommended that a self-test of all the units in
your Wi-Safe 2®network is carried out weekly.
In addition the network should also be tested
whenever:
• An additional alarm or ancillary product is added to
the system.
• There are changes to the structure of your property.
•There are significant changes in the position of
large items of furniture or electrical products in your
home.
•You replace the battery in any product within the
Wi-Safe 2®network.
The Low Frequency Sounder is now ready to be
placed into position.
If you are testing the Low Frequency Sounder for
the first time during installation and it does not test,
please repeat the “learn in” procedure.
If you are unable to resolve the problem please
contactTechnical Support on 0800 141 2561.
The Low Frequency Sounder is independently tested
as being compliant with the applicable British and
European standards. However, as with any electronic
product, it could fail and may not produce an
indication of smoke or CO within sufficient 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 Low Frequency Sounder and
all alarms in the Wi-Safe 2®network system every
week to ensure the whole system is in full working
order and that the wireless interlink (RF) between
the alarms and ancillary products has not been
compromised.
NOTE: The Low Frequency Sounder, smoke and
CO alarms should not be considered as a substitute
for life or property insurance. The Low Frequency
Sounder should be replaced immediately in the event
of failure, and the rechargeable battery should be
replaced every 5 years.

11
POSITIONING
Where should the Low Frequency Sounder be
installed?
If you have one Low Frequency Sounder, it should
be installed in the main room where you sleep. You
may wirelessly interlink additional Low Frequency
Sounders to the network and install them in any room
where you may need to be alerted in the event of an
alarm. It is important that if you install additional
Low Frequency Sounders you test each of these upon
installation to check they are “learned in” to the rest
of the network.
Wireless Range: The wireless range of Wi-Safe 2®
products is over 200 metres in clear air/clear line of
sight. However it is recommended not to exceed 35m
as the maximum distance between any interlinked
Wi-Safe 2®smoke alarm or carbon monoxide alarm
from the Low Frequency Sounder.This is because the
range can be reduced by walls, and other obstructions
in the building.
Position the Low Frequency Sounder:
• Close to a power socket where it can be easily
plugged in and the cable does not create a tripping
hazard.
• Where you can see the LEDs on the front of the unit.
NOTE: the Low Frequency Sounder can be fitted to a
wall or placed on a shelf or table.
CAUTION: Do not put the Low Frequency
Sounder
• Outside the building.
• In a cupboard.
• In a damp or humid area.
• In an area where the temperature could regularly
drop below –5°C or rise above 40°C.
• Anywhere where the unit can easily be knocked or
damaged.

12
If placing the Low Frequency Sounder on a table
or shelf instead of mounting on the wall, make
sure it cannot easily be knocked or slide off. Once
plugged in, the green “power” LED should illuminate
continuously to show that the AC power supply is
connected.
LIMITATIONS
NOTE: This Low Frequency Sounder is not
compatible with products from the original
Wi-Safe product range.
INSTALLING THE LOW
FREQUENCY SOUNDER
We recommend wall mounting the Low Frequency
Sounder. To do this, drill two suitably sized holes
37mm apart, centre to centre, using the template (fig
7).
37mm
Drill hole spacing
Warning: Make sure that you check for electrical
cabling and pipework hidden in the wall before
carrying out any drilling). In the pack you will find
two screws and two screw anchors. Push the screw
anchors (if needed) into the drill holes and secure the
screw leaving the heads protruding so that the face of
the head is 5mm away from the wall. Now hook the
Low Frequency Sounder onto the screws (fig 8).

• The Low Frequency Sounder will not operate in
isolation, with non Wi-Safe 2®Alarms, or any alarms
made by other manufacturers.
• The Low Frequency Sounder may not respond to
the signal from the Wi-Safe 2®alarm if the alarm
and the Low Frequency Sounder are too far apart
(see “Positioning”).
• The Low Frequency Sounder may not respond to
the signal from the Wi-Safe 2®alarm if there are
obstructions that significantly reduce the signal
(eg: steel reinforcement in concrete). Always test
the operation of the Low Frequency Sounder with
all other alarms and units in the network after any
changes to the building structure or in the position
of large items of furnitwure.
DANGER: Under no circumstances should this
product be immersed in water, or used in an area
where water may come into contact with the product.
OPERATION
1. Standby Mode, but not “learned in” to a
network.
The amber (fault) LED will be illuminated .
2. Standby mode
The Low Frequency Sounder should be connected to
the mains AC supply and placed in a suitable position.
The Green “power” LED on the Low Frequency
Sounder will be permanently illuminated .
3. Alarm mode
When a Wi-Safe smoke or CO alarm goes into
“alarm” mode the RESPECTIVE red alarm LED will
flash rapidly and the Low Frequency Sounder will
sound as follows:
• Red ‘smoke’ LED & repeated cycles of 3 loud beeps
– SMOKE
• Red ‘CO’ LED & repeated cycles of 4 rapid beeps –
CO
• Both red LEDs flashing rapidly and repeated cycles
of 3 loud beeps – SMOKE and CO
NOTE: The Low Frequency Sounder will silence and
the red alarm LED will cease to flash when the alarm
sending the signal has been reset or has stopped if
the danger is no longer present.

14
Only reset an alarm if you are certain there is no
imminent danger from Fire or Carbon Monoxide.
Locate Feature:
When the network is in alarm mode, pressing the
test button on any unit in the network will silence all
other alarms in the network, for a period of 2 minutes,
except the alarm that has sensed smoke or
carbon monoxide. This will enable the instigating
alarm to be identified/located. If necessary, the
instigating alarm can then be silenced.
UNPLUGGING FROM
THE MAINS/POWER CUT
The Low Frequency Sounder is designed to be mains
powered. The internal rechargeable battery will still
provide power if the mains fails. A fully charged
battery will allow the Low Frequency Sounder to
continue to operate for three days. NB Only use the
battery supplied in the pack or a genuine FireAngel
replacement. Other batteries may damage the
equipment or create a safety hazard.
WARNING: When the mains power is
disconnected, the green power LED will no
longer illuminate. Plug the Low Frequency
Sounder back into the mains as soon as
possible to recharge the battery and maintain
correct operation.
If the amber (fault) LED is flashing once every
5 seconds when the green power LED is off
then URGENTLY restore power to the unit as
the battery status is very low, and may fail to
operate in an alarm situation.
NOTE: Once the Low Frequency Sounder is
plugged back into the mains, the amber (fault)
LED will continue to flash once every 5 seconds
until the battery has fully recharged.

Smoke and CO Alert
The Smoke LED (red) will flash

17
• Stay close to the floor. 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 service on 999 as soon as possible from
outside your house. If possible use a neighbour’s
phone or call box rather than a mobile phone (as
the location can be traced from the number if the
line is lost).
• Give the address and your name.
• Never go back inside the building until a member
of the fire service has told you it is safe to do so.
If after proceeding with extreme caution you have
been able to confirm that your Low Frequency
Sounder was triggered by a nuisance alarm (which
may occur from time to time from cooking or other
non-emergency situations) you should silence the
smoke alarm that has been triggered. This will
silence the Low Frequency Sounder. It is important
to practice escape plans and show everyone in the

What to do in Case of 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 safely. Go over the following rules with
your children each time you have a fire drill. 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 residence of the fire.
• 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 to see if they are hot. If they are
hot, do not open them - use an alternative escape
route.

WHAT TO DO IN THE EVENT
OF A CARBON MONOXIDE
ALARM TRIGGERING THE
LOW FREQUENCY SOUNDER
ASSUME CARBON MONOXIDE HAS BEEN
DETECTED INYOUR HOME!
WARNING: A loud alarm is a warning that
unusually high and potentially lethal levels of
carbon monoxide are present. Never ignore this
alarm; further exposure could be fatal. Immediately
check residents for symptoms of carbon monoxide
poisoning, (see product manual) and contact the
proper authorities to resolve all CO problems.
NEVER IGNORE ANY ALARM.
What to do during an alarm:
• Keep calm and open the doors and windows to
ventilate the property.
• Stop using all fuel burning appliances and ensure,
if possible, that they are turned off.
• Evacuate the property leaving the doors and
windows open.
• Ring your gas or other fuel supplier on their
emergency number; keep the number in a
prominent place.
• Do not re-enter the property until the alarm has
stopped. When exposed to fresh air it can take up
to 10 minutes for the sensor to clear and the alarm
to stop depending on the level of carbon monoxide
detected.
• Get medical help immediately for anyone suffering
the effects of carbon monoxide poisoning
(headache, nausea, drowsiness), and advise that
carbon monoxide poisoning is suspected.
• Do not use the appliances again until they have
been checked by an expert. Contact a Gas Safe
registered engineer in the case of a gas appliance.
