LOCATING THE SMOKE ALARM
This smoke alarm is a photoelectric alarm with build-in
wireless interconnection. It can transmit and receive with
other smoke alarms.
If your dwelling is on a single storey, for minimum protection
you should fit an alarm in the hallway between the living
areas (incl. Kitchens) and sleeping areas. Place it as near to
the living areas as possible and ensure the alarm is audible
when the bedrooms are occupied. See Figure 1 for
examples.
If your dwelling is multi-storey, for minimum protection one
alarm should be fitted at the bottom of the staircase with
further alarms fitted on each upstairs landing. This includes
basements but excludes crawl spaces and unfinished attics.
See Figure 2 for examples.
NOTE: For maximum protection an alarm should be fitted in
every room (except kitchen, bathroom and garage).
DO NOT FIT AN ALARM IN THE KITCHEN or BATHROOM,
as cooking fumes or steam may trigger the alarm.
DO NOT FIT ALARM IN A GARAGE, as exhaust fumes are
likely to set it off.
POSITIONING THE SMOKE ALARM
Ceiling Mounting
As hot smoke rises and spread out, it is advisable to mount
on a ceiling in a central position. Avoid areas where there is
no air circulation. E.g. Corners of rooms and keep away from
items which may prevent the free flow of air. Place the unit at
least 300mm from and light fitting or decorative object which
might obstruct smoke / heat entering the alarm. Keep at
least 300mm away from walls. See Figure 3i.
On a Sloping Ceiling
In areas with sloping or peaked ceilings install your Smoke
Alarm 900mm from the highest point measured horizontally
because “dead air” at the apex may prevent smoke from
reaching the unit. See Figure 3i.
FIGURE 1 – SINGLE STOREY DWELLING
FIGURE 2 – 2/3 STOREY DWELLING
Areas to be avoided include the following :-
• Situations where the temperature may fall below
0oC or rise above 40oC
• Humid areas such as bathrooms, kitchens, shower
rooms where the relative humidity may exceed 90%
• Near a decorative object, door, light fitting, window
molding etc., that may prevent smoke or heat from
entering the alarm.
• Fume filled environments such as garages.
Exhaust gases may cause false alarms.
• Adjacent to or directly above hot components such
as radiators or wall vents that can effect the
direction of air currents.
• In dusty or dirty environments such as workshops.
• Locate unit at least 1.5m away for fluorescent light
fittings as electrical “noise” and/or flickering may
affect the unit.
• Do not locate in insect infested areas. Insects and
contamination on the Heat Alarm sensor can
increase its response time.
INSTALLING THE SMOKE ALARM
This smoke alarm is powered by battery and requires no
additional wiring.
• Having established the mounting location ensures
that there in no electrical wiring or pipe work in the
area adjacent to the mounting surface.
• Take the mounting bracket and mark the two
mounting hole locations.
• Drill holes in the positions marked.
• Insert wall plugs into the drilled holes.
• Screw mounting base to mounting surface. Apply the
included screws into the two holes and secure the base
firmly. DO NOT OVER TIGHTEN.
• Each unit carries a four positions dip switch (see diagram)
for coding the transmit and receive frequency to prevent
interference with any other RF equipment. There are 16
combinations.
IMPORTANT!
The setting of the dip switch must be the same on all
interconnected units.
• Insert the battery in the battery compartment located in
the upper smoke alarm unit. This can be accessed by
separating the unit apart, simply push-in the clips on both
sides of the unit simultaneously.
NOTE – For the safety of the end user the smoke alarm
cannot be fitted without its battery.
• Attach the upper smoke alarm unit firmly.
• Test the alarm for correct operation using test facility,
once the alarm is integrated and installed.
IMPORTANT!
Please insert the included 9V battery for operation.
The button on the base unit is only used to
connect the detector to a panel (DC-108,
accessories)

4 POSITIONS DIP SWITCH
The button on the
base unit is only used
to connect the
detector to a panel
(DC-108,
accessories)

OPERATING YOUR SMOKE ALARM
Once the smoke alarm has been installed a small indicator
light (LED), positioned beside the test button, and should
flash approximately once a minute in normal operation.
If smoke is detected the unit will emit a load pulsating alarm
until the air is clear.
At normal time, the product is working under sleep mode. It
will open the receiving window at a short time around every
16 seconds. In order to awake it and set it at transmission
mode, the simplest way is to press the test button on top of
the smoke detector. It will continually transmit as long as the
button is pressed.
To test two units’ transmission and reception performances/
parameters, it is important to set them with the same code.
The dip switch for setting the code is available on the base of
the unit. When one is at its receiving mode, it can receive a
triggering signal from the transmitting unit within 16 seconds.
As soon as the receiving unit gets the signal, it will activate
the alarm to sound loudly until the transmitting signal is
vanished.
TESTING YOUR SMOKE ALARM
It is recommended that you test your smoke alarm once a
week to ensure the detector is working correctly.
Push and hold the test button for approximately 3 seconds. A
loud pulsating alarm should sound to indicate the correct
function. During the alarm condition the indicator light will
flash quickly.
After installation and after reoccupation of the
dwelling following a vacation etc, check all your
alarms.
COMMON CAUSES AND AVOIDANCE OF
FALSE ALARMS
The Smoke Alarm may be triggered by steam, condensation,
normal smoke or fumes. Small insects getting into the smoke
alarm chamber may cause intermittent alarms. Keep away
from the sources to avoid nuisance alarms. (See "Areas to be
avoided" in the "Positioning the smoke alarm" section.)
Hush or Silence Feature
This Smoke Alarm has a built-in Hush or Silence feature
incorporated into the Test button. If cooking or other non-
hazardous sources cause the unwanted alarm, it can be
temporarily silenced by depressing the test button and
holding for approximately 3 seconds. The alarm will enter a
dormant period for 10 minutes. The red LED will flash every
10 seconds to indicate the sensitivity is reduced. At the end of
the hush period the alarm will reset to normal sensitivity.
NOTE - If the smoke density increases during this period (i.e.
from a fire) the unit will go into alarm mode.
LOW BATTERY WARNING
If the smoke detector emits a short ‘beep’ once a minute the
battery is at the end of its life and should be replaced
immediately. This low voltage warning will be given for at
least 30 days.
In this case, the other interconnected units in the system
which are not in low battery condition will chirps for a few
seconds once a hour as long as the detector with the “dead”
battery beeps.
If the red indicator light (LED) does not flash every minute
then replace the battery.
BATTERY REPLACEMENT
• This smoke alarm requires 1 piece 9V battery (alkaline
or lithium). Normally, its average service life is 12
months for alkaline type, longer for lithium types,
approx. 3-5 years.
• Replace the batteries immediately once the smoke
alarm start beeping (the low battery warning)
• Remove the battery by gently pulling it away from the
connection pad.
• Insert 9V battery firmly into battery compartment.
NOTE POLARITY OF CONNECTIONS. Ensure the
battery is connected firmly.
• Re-attach the upper smoke alarm unit to the mounting
base.
• Test the alarm for correct operation using the test
facility, whenever the battery is replaced.
CAUTION: Danger of explosion if battery is incorrectly
replaced. Replace only with the same or equivalent type.
The use of batteries other than those recommended on
the back of the smoke alarm may be detrimental to its
operation.
“STOPPER” ENSURING PROPER BATTERY
INSTALLATION
The unit will not operate without battery. When battery is
removed from the alarm, the safety plate “STOPPER” will
block the keyhole slot which avoids the alarm to be installed
onto the transmitting base.
ACTION IN THE EVENT OF A FALSE ALARM
• If there is a false alarm, simply press the test / hush
button on the cover to mute the unit for 10 minutes.
• Check the house carefully in case there is a small fire
smouldering somewhere.
• Check whether there are some sources of smoke or
fumes. You should get your family into a safe place
before your investigation.
• If there are frequent nuisance/ false alarms it may be
necessary to re-locate the device. If for some reasons
the alarm continues to give false alarm, the units can
be silenced by removing the batteries. If cleaning the
alarm does not correct the problem it can be returned
to the place where you bought it.
IN THE EVENT OF FIRE
• Leave the building as quickly as possible. Check room
doors for heat or smoke. Do not open a hot door. Use
an alternate escape route. Crawl along the floor, if
possible, through a wet cloth or hold your breath.
Do not stop to collect anything.
• Meet at a pre-arranged meeting place outside the
dwelling and check everybody is there.
• Call the Fire Brigade from outside the building
immediately. The brigade should be summoned
regardless of the size of the fire and regardless of
whether there is a facility for transmission of alarms
to a remote manned centre.
• Do not go back inside a burning building and wait
for the Fire Brigade to arrive.
MAINTAINING YOUR SMOKE ALARM
Clean your smoke alarm regularly to prevent dust build up.
This can be done using a vacuum cleaner with the brush
attachment. Clean gently around the front grilled section
and sides. Never use water, cleaners or solvents since
they may damage the smoke alarm.
When the battery is low, replace with a fresh one.
If the alarm fails to operate correctly, please send back to
the address of manufacturer shown on the back label of
the detector.
NOTE: THE APPARATUS SHALL NOT BE EXPOSED
TO DRIPPING OR SPLASHING.
IMPORTANT SAFEGUARDS
Installation of your smoke alarm is only one step in your
safety plan. Other important steps should be taken to
further improve your safety:-
• Install the smoke alarm properly, following this
instruction leaflet
• Test your smoke alarm weekly
• Replace the battery immediately once depleted
• Do not smoke in bed
• Keep matches & lighters away from children
• Store flammable materials in a proper manner and
never use them near naked flames or sparks
• Maintain emergency equipment such as Fire
Extinguishers, escape ladders etc and ensure all
occupants know how to use them correctly.
• Plan an escape route/s from your building in
advance and ensure all occupants are aware of
them. Re-enforce this awareness periodically
through-out the year.
• Make sure escape routes remain free of any
obstructions.
