SAFETY WARNING
• The installation should be carried out by a qualified electrician in compliance with the current edition
of the IEE Wiring Regulations.
• Prior to installation carry out the necessary risk assessment considering the people who could be at
risk, the level of risk and the precautions required to control the risk.
• Ensure that the circuit supply is isolated either by the circuit supply fuse being removed or the
applicable circuit breaker being turned o before installation or any maintenance.
• Check the total load on the circuit including the luminaire does not exceed the rating of the circuit
cable, fuse or circuit breaker.
• If the fitting incorporates control gear, ensure careful sizing to avoid instances of nuisance tripping of
the protective device used in the installation.
• Follow the provided installation instructions, using the fixings supplied or recommended.

INSTALLATION INSTRUCTIONS -
LOCATING THE SMOKE ALARM
• If your dwelling is on a single storey, for minimum protection you should fit an
alarm in a corridor or hallway between the sleeping and living areas (incl.
Kitchens).
• Place it as near to the living areas as possible and ensure the audible alarm can
be heard when the bedrooms are occupied. See Figure 1 (above) for example.
• 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 example.
NOTE: For maximum protection an alarm should be fitted in every room (except
kitchens, bathrooms and garages).
DO NOT FIT AN ALARM IN THE KITCHEN OR BATHROOM, as cooking fumes or
steam may trigger the alarm.
DO NOT FIT AN ALARM IN A GARAGE, as exhaust fumes are likely to set it o.

• Connect the wires to the correct terminals (on the mounting base) incoming
supply. If the smoke alarm is to be interconnected, link out the interconnection
terminals. Ensure the screws are fully tightened. See Figure 6.
LIVE: Connect to house the wires coloured Brown, Red or marked with L.
NEUTRAL: Connect to house wires coloured Blue, Black or marked with N.
INTERCONNECT: Normally not used except to hardwire interconnect to the
mains smoke (SMAS-P2) or heat alarm (SMAS-P2). Never use the EARTH wire
for the interconnect wire.
• Insert a 9V battery firmly into the battery compartment on the rear of the
alarm. NOTE POLARITY OF CONNECTIONS. Ensure the metal tab is fully
depressed when the battery has been fitted.
NOTE – For the safety of the end user the smoke alarm cannot be fitted without
its battery.
• Before assembling the smoke alarm to the base plate, test the correct operation
of the smoke alarm (operating from the battery only) by depressing the test
button on the front of the alarm. The unit should emit a loud pulsating alarm.
• Assemble the alarm unit onto the mounting plate by
turning the alarm unit counter-clockwise. See Figure 4.
• Restore the AC supply by plugging the AC QUICK
CONNECTOR into the back of the alarm (see Figure 4).
Make sure that the locks on the connector snap into
place.
• Test the correct operation of the smoke alarm by
depressing the test button on the front of the detector.
The unit should emit a loud pulsating alarm.
• Use a 2.1mm wire for connection.

• In very dusty or dirty environments, such as workshops.
• Locate the unit at least 1.5m and route wiring at least 1m away from
fluorescent light fittings as electrical “noise” and/or flickering may aect
the unit. Do not wire into the same circuit as fluorescent lights or dimmers.
• Do not locate in insect infested areas. Insects and contamination on the
alarm sensor can increase its response time.
INSTALLING THE SMOKE ALARM
• The circuit used to power the smoke alarm must be a dedicated permanent
supply that cannot be switched o accidentally by the normal user. Before
installing ensure the electrical supply is isolated.
WARNING: To prevent injury, this smoke alarm must be securely attached to
the ceiling/wall in accordance with the installation instructions.
• The Smoke Alarm will function correctly either as a stand-alone alarm or
inter-connected.All Inter-connected Smoke Alarms must be supplied from
a single power circuit. A common neutral must be used for the
interconnect to function.
WARNING: Do not connect the interconnect wire to Live or Neutral.
• Disconnect the AC main power from the circuit that is going to be used.
• Having established the mounting location, install a junction box suitable for
locating the termination point. Ensure that there is no other electrical
wiring or pipe work in the area adjacent to the mounting surface.
• Unlock the detector unit from the base by pushing back the snap lock with
a screw driver and turn the alarm unit anti-clockwise to release it. See
Figure 5 and 6.
• Fix the mounting plate in position.
• Strip the Live/Neutral and Inter-connect (if used) wires.

POSITIONING THE SMOKE ALARM
Ceiling Mounting
• As hot smoke rises and spreads out, it is advisable to mount on a ceiling in a
central position, avoiding 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 any light fitting or decorative object which
might obstruct smoke entering the alarm. Keep the unit at least 300mm away
from walls. See Figure 3i.
Wall Mounting
• Do not mount the unit tight into the corners. Put the top edge of your smoke
alarm between 150mm and 300mm below the ceiling. Keep the unit at least
300mm from room corners. 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 3ii.
Figure 3i & 3ii - Positioning the smoke / heat detector
Areas to be avoided include the following:
• Situations where the temperature may fall below 0°C or rise above 40°C.
• Humid areas such as bathrooms, kitchens and shower rooms, where the
relative humidity may exceed 90%.
• Near a decorative object, door, light fitting, window molding etc., that may
prevent smoke 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 eect the direction of air currents.

OPERATING YOUR SMOKE ALARM
• Once the smoke alarm has been installed a small GREEN indicator light (LED)
should be visible through the alarm grill, indicating that the AC supply is
healthy. A RED indicator light (LED) should also flash approximately once a
minute to indicate the battery is healthy and the unit is operating properly.
• If smoke is detected, the unit will emit a load pulsating alarm and a RED
indicator light (LED) will be flashing quickly at the same time until the air is
clear.
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 three seconds. A loud
pulsating alarm should sound and a RED indicator light (LED) will flash at the
same time.
