SMOKE ALARM SENSOR TECHNOLOGY
Thermoptek®technology combines the very latest in optical sensing with a thermal enhancement
providing a fast reaction to both fast aming and slow smouldering res in a single alarm.Thermoptek
technology constantly monitors for temperature change. If a rate of temperature rise is detected the
sensitivity of the smoke alarm is increased, providing a quicker response time to both re types.
HEAT ALARM SENSOR TECHNOLOGY
Thermistek™ technology incorporates a unique radiant heat dish (patent pending) to heighten
performance when exposed to a radiant heat source in real re situations. Constantly monitoring
for temperature change, if an increase in temperature is detected, the rate of rise is measured and if
predicted to exceed a pre-determined threshold will sound the alarm.This predictive quality provides
a quicker response time in rapidly increasing temperatures.
Heat alarms are designed for areas where dust and fumes may trigger frequent nuisance alarms in
conventional smoke alarms - ideal for attics, garages and kitchens. The HM-SN-1 / WHM-SN-1 are
xed point heat alarms usingThermistek sensing technology. All alarms are approved to class A1 and
will activate when the temperature reaches a preset range of 54 °C to 65 °C.
LITHIUM BATTERY TECHNOLOGY
All SONA mains powered smoke and heat alarms have a built in, sealed for life lithium battery (back-
up); designed to power the alarm in the event of a mains failure.
DO NOT:
• Expose this alarm to moisture, dripping, splashing, steam or condensation.
• Paint the alarm.
• Install heat alarms in escape routes instead of smoke alarms.
• Test your alarm with a naked ame.The test button tests the alarm’s full functionality.
• Ignore any alarm in the network if it is sounding, it is warning you of a potentially hazardous
situation.

SYSTEM GRADES AND CATEGORIES
The mains powered SONA™ alarms with 10 year life are suitable for Grade D systems. It is important
to determine the correct alarm system grade and category for the dwelling prior to installation.
A Grade D system is required for:
• New or materially altered dwellings, up to three storeys with no oor exceeding 200 m2.
• Existing dwellings with poor or inadequate re protection, up to three storeys with no oor
exceeding 200 m2.
• Individual dwelling units of two or more rooms in Houses in Multiple Occupation (HMOs) of one
or two-storeys, with no oor exceeding 200 m2.
There are three Levels of Detection (LD). Generally the greater the re risk the more comprehensive
the system should be.
LD1 = Maximum Protection. Alarms in all circulation spaces that form part of escape routes and all
areas where a re might start.
LD2 = Medium Protection. All circulation spaces and escape routes (e.g. hallways and landings) are
covered together with a provision of higher re risk areas (e.g. kitchen and living rooms).
LD3 = Minimum Protection. Alarms in all circulation spaces that form part of escape routes.
* Ensure that a Grade D system is adequate for the dwelling you are installing the alarms in.

7
DO:
• Install smoke alarms in circulation areas at a distance no greater than 7.5 m from the farthest
wall, no greater than 7.5 m from a door to any room in which a re might start and no greater
than 7.5 m from the next smoke alarm.
• Install heat alarms on the ceiling, ideally in the centre of the room.
• Install sufcient alarms to compensate for closed doors and obstacles.
• Install yourThermistek heat alarm at a distance no greater than 5.3 m from the farthest wall, no
greater than 5.3 m from a door to any room in which a re might start and no greater than 5.3m
from the next heat or smoke alarm.
✓
POSITIONING
Locations of alarms must be compliant with either BS 5839: Part 6 or relevant Building Regulations if
in any doubt.This alarm is not intended for any non-residential, commercial or industrial application,
nor for any other purpose other than described in the above. For the best protection, heat alarms
should always be installed as part of a complete re protection system that includes smoke alarms.

HARDWIRE INSTALLATION
The alarm base plate is designed to be permanently mounted, using its own built-in terminal block to
connect it to the mains.The base plate can be screwed directly to the ceiling.
• IMPORTANT: The circuit used to power the alarm must be a 24 hour voltage circuit that cannot
be turned off by a switch. BS 5839: Part 6 states that: For mains powered alarms, each with an
integral standby supply (Grade D), the mains electricity supply should take the form of either
a) an independent circuit at the dwelling’s main circuit board, in which case no other electrical
equipment should be connected to this circuit (other than a dedicated monitoring device installed
to indicate failure of the mains electricity supply to the alarms); or b) a separately electrically
protected, regularly used local lighting circuit.
• Ensure a permanent connection to the xed wiring of the building is made in a suitable
junction box.
• Remove the terminal block cover.
• If trunking is required, snap the break-out tab away from the base plate prior to connection.
• The wiring must be connected to the terminal block as follows:
Live (L) - Connect to the Live in the house wiring.
Neutral (N) - Connect to the Neutral in the house wiring.
Interconnect (I) - If desired, join the Interconnect wire between the alarms.
• Use the terminal to safely terminate any copper Earth or green / yellow cable.
×DO NOT:
• Install the alarms within 1500 mm (1.5 m) of a uorescent light tting and keep wiring at least
1000 mm (1 m) from these ttings.
• Install alarms on circuits containing uorescent light ttings or dimmer switches.
• Install alarms within 300 mm (12”) of light ttings or room corners.
• Install smoke alarms in wall positions that are less than 100 mm (4”) or more than 300 mm (12”)
away from the ceiling.
• Locate theThermoptek smoke alarm close to bathrooms or showers as it can be susceptible to
nuisance alarms from steam.
• Install heat alarms on a wall.

WARNING: Mixing the Live and Neutral
connections when interconnecting alarms will
damage all the alarms. DO NOT use the Earth
wire for the interconnect connection.
Either feed the wire through the hole in the base
plate or through theYT2 trunking.

HARDWIRE INTERCONNECT - SM-SN-1 and HM-SN-1
DO NOT:
• Exceed the maximum of 30 interconnected alarms on a network.
• Exceed 250m of connecting wire per circuit.
• Connect SONA alarms to any other models produced by another manufacturer.
For multiple alarm installations use a ‘three core and earth’ style cable between all the alarms to be
interconnected. Connect the interconnect cable between each alarms 'I' terminal. The interconnect
wire (minimum 0.75 mm2 cable) must be treated as Live, it should be insulated and sheathed.

×DO NOT:
• Exceed the maximum of 50 alarms interlinked in a network.
• Connect SONA alarms to any models produced by another manufacturer.
The SONA WSM-SN-1 and WHM-SN-1 are designed to be wirelessly interlinked with up to
50 products within the Wi-Safe 2 product range.They are not designed to communicate with wireless
alarms from other ranges or manufacturers. These alarms need to be ‘learned-in’ or interlinked
in order to communicate with each other. If one alarm activates, all other interlinked alarms will
also sound.
Wi-Safe 2 eliminates the need for interconnecting wires around a property making future system
modications easy and cost effective. AC Smoke and Heat alarms will still need a mains supply in
accordance with BS 5839: Part 6 and Building Regulations.
IMPORTANT: Obstructions such as steel reinforcement in concrete could block or impede the wireless
signal. While the wireless range is over 200 m in clear air / clear line of sight, the effective range may
be reduced by walls and other obstructions in the building. It is recommended not to exceed 35m as
the maximum distance between alarms in a network.

How to ‘learn-in’ two wireless alarms into a network:
Install Alarm 1 as described earlier (see 'Hardwire Installation'). Install the base plate for Alarm 2 in
one of the recommended locations.
1. Using a ballpoint pen briey push and
release the 'learn button' on the back of
Alarm 2. The red LED next to the learn
button will ash briey then light up for
approximately 5 seconds.
2. During these 5 seconds you need to
briey press the test button on Alarm 1 to
wirelessly interlink the two alarms. Alarm
1will give an audible sound consisting of
two cycles of three loud beeps.
3. The red LED on the wireless module of
Alarm 2 will ash to indicate that it has
been ‘learned-in’ successfully. If the test
button is not pressed quickly enough, the
‘learn-in’ process will fail. If this happens,
repeat the process.
Learn button
To complete the installation, t Alarm 2 onto its base plate. Additional alarms should be ‘learned-in’
in the same way. When ‘learning-in’ additional alarms, any alarm already in the network, can be used
as ‘Alarm 1’.You do not have to ‘learn-in’ to every alarm in the network.

13
DO:
• Ensure there is only one wireless connection into each network. For example if you
have a hardwired network upstairs and a wireless network downstairs only one
of the hardwired products should be linked into the wireless network, connecting
both systems.

ALARM SMART SILENCE™
Your alarm features 'Smart Silence' technology. In the event of a known false alarm your alarm can
be temporarily silenced by pressing the central test button. Your alarm will automatically return to
full sensitivity within 10 minutes.
During the reduced sensitivity mode the red LED on your alarm will continue to ash more rapidly
than normal, approximately once every 10 seconds. Only use the alarm silence function after making
sure that there is no re emergency situation. Do not block the vents on the alarm or disable the alarm
in any way, as this will remove your protection.
NOTE: If the level of heat / smoke reaching the alarm is very high the alarm silence will be overridden
and the alarm will continue to sound.
SLEEP EASY™
Low battery warnings often start at night or when it may be inconvenient to replace your alarm.
You can silence the audible 'low battery' chirp for a period of 8 hours by pressing the test button.
After this period the audible chirp will start again.This process can be repeated for a maximum of 10
times.Your alarm will still detect heat /smoke during this time, however you must replace your alarm
within 30 days, as it may have insufcient power to warn you of a real re situation after this time.
WARNING: Your 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 re.

TROUBLESHOOTING
Problem Solution
Your SONA alarm
does not sound
during testing
• Make sure you push the centre of the test button rmly.
• If the alarm has been recently tted and it still fails to self test then contact
Technical Support.
• If you are in the process of 'learning-in' the alarm and it does not test,
repeat the process.
The green
LED does not
illuminate when
the mains power
is on
• Make sure the alarm is correctly located on the base plate.
• Ensure the mains power supply is on.
• Inspect the circuit breaker / fuse in the power circuit to the alarm.
• Call a qualied electrician to inspect the house wiring and connection.
The amber LED is
ashing and the
alarm is making a
'chirping' sound
• If the amber LED is ashing at the same time as the chirp, this indicates
a low battery condition and the alarm should be replaced as soon as
possible and certainly within 30 days.
• If the amber LED is ashing at a different time to the chirp, this indicates a
fault and the alarm should be replaced as soon as possible.
• If the amber LED is double ashing and the alarm is making a 'chirping'
sound, this indicates that the wireless module has a low battery condition,
or is faulty.The alarm should be replaced as soon as possible.
Your SONA
alarm chirps
intermittently
• Check the location of your alarm (see ‘Positioning’).
• Check that your alarm is denitely the source of chirping; make sure the
noise isn’t coming from another alarm.
• If the alarm is chirping once approximately every 45 seconds and the
amber LED is ashing around the same time, it indicates that the battery is
low.The unit should be replaced within 30 days.
• If the 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 and replace the alarm as soon as possible and in any
event within 30 days.

17
Your SONA
alarm fails to
successfully
learn-in to a
network
• Make sure your alarm is 'unlearned' before trying to learn-in to a network.
Do this by pressing and releasing the learn-in button located on the back
of the alarm, immediately press and hold the learn-in button, during which
the red LED will remain solid. When the LED goes out, release the button.
The LED will ash twice followed by three quick ashes, indicating that it
has successfully been unlearned.You can then follow the learn-in process
as described in 'Wireless Interlink'.
Other interlinked
units fail to
silence when one
unit is silenced
• Interlinked units that have sensed smoke / heat can’t be silenced remotely.
If one or more units remain in alarm, all other interlinked units will emit
their audible warning again within 4 minutes. Vacate property if there is a
re hazard.
WARNING: Storage in low humidity and certain transportation conditions may cause electrostatic
charges to build up in the alarm system housing. Although harmless this may increase the length of time
that the horn sounds upon test button operation. The condition may be cleared by wiping the inside and
outside of the plastic cover with a damp cloth.
If you have any questions about the operation of your alarm, please contactTechnical
Support between 9am - 5pm Monday – Friday. Telephone: [phone] or e-mail:
tec[email protected] You can also visit the support section of our website

BE PREPARED
Smoke and heat alarms properly installed and maintained are an essential part of a good home
safety programme. Review re hazards and eliminate dangerous conditions whenever possible.
When re strikes, a prepared and practised escape plan could prove vital. Consider and discuss the
following hints:
• Ensure everyone is familiarised with the
alarm signal.
• Always test doors with your hands before
inging them open. If they feel warm, re
may have walled up behind them – leave
closed and nd another escape route.
• Don’t waste time collecting possessions.
Arouse all occupants and leave the building.
Your life is more valuable!
• GET OUT, STAY OUT, GET THE FIRE
BRIGADE OUT.
• Keep everyone in a set meeting place after
you escape.
• If trapped inside, stay close to the oor, cover
your mouth with a cloth and conserve breath
as you crawl to safety.
• Keep all windows and doors closed except for
escape purposes.
• Prepare and practice an escape plan before a
re starts.
• Draw a oor plan. Have re drills often.
Practise your escape.
IF THERE IS ANY QUESTION AS TO THE CAUSE OF THE ALARM, ALWAYS ASSUME THAT THIS IS AN
ACTUAL FIRE AND FOLLOW YOUR FIRE EMERGENCY PLANS.

19
Your smoke and heat alarms should be cleaned
every 3 months, by rstly turning off the mains
electricity supply and then using a vacuum
cleaner tted with the soft brush attachment.
Switch the power back on once you have
nished.
DISPOSAL
Waste electrical products should not be disposed of with your other household waste. The alarm is ideally suited for
disposal within the waste electronic and electrical equipment (WEEE) recycling scheme. Please recycle where facilities
exist. Check with your local authority, retailer or contact Technical Support for recycling/disposal advice as regional
variations apply. Your alarm can be unlearned from a network, as described in 'Troubleshooting'. Once it is removed
from its base plate it is automatically disabled and ready to be disposed of.
WARNING: Do not burn or dispose of in re. WARNING: If your alarm is dropped or damaged, as a precaution, it should be
removed from the building.
