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
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.
