Recommended Location o Alarms
• Emerging smoke rises to the ceiling and spreads horizontally. Mounting the alarm on
the ceiling close to the centre of the room provides the best protection. Ceiling
mounting, rather than wall mounting, is preferred in normal residential construction.
• When mounting alarms on the ceiling locate it at least 300mm away from the side
wall and 300mm away from any corner. (see diagram overleaf).
• When mounting alarms on a wall, use the inside wall. The recommended position is
between 300mm and 500mm o the ceiling. (see diagram overleaf).
• When mounting the alarm at the apex of a sloping ceiling it should be located at
least 500mm away from the apex but should not exceed 1500mm (see diagram
overleaf).
• Locate at least one alarm on every oor level.
• Locate an alarm in every room where electrical appliances are operated (i.e. Portable
heaters or humidiers).
• Locate an alarm for each separate sleeping area in the immediate vicinity of the
bedrooms. Monitor the exit path as the bedrooms are usually farthest from an exit.
• Locate smoke alarm at both ends of a bedroom hallway or large room if the hallway
or room is more than 9m long.
Note: The performance of smoke alarms mounted on walls is unpredictable and this
mounting position is not recommended when ceiling mounting can be implemented.
4

Recommended Location o Alarms
• Locate additional alarms to monitor any stairway as stairways act like chimneys for
smoke and heat.
• For mobile home installation select location carefully to avoid thermal barrier that
may form at the ceiling. For more details see Mobile Home Installation.
• Do not locate smoke alarms in kitchen areas due to potential nuisance alarms from
cooking fumes.
• Incorrect orientation of smoke alarm may decrease operation eectiveness.

Mobile Home Installation
• Modern mobile homes have been designed and insulated to be energy ecient.
Install smoke alarms as recommended (refer to Recommended Locations).
• In older mobile homes that are not well insulated compared to present standards,
extreme heat or cold can be transferred from the outside through poorly insulated
walls and the roof. This may create a thermal barrier which can prevent smoke from
reaching a smoke alarm mounted on the ceiling. In such units, install smoke alarm on
inside partition between 300mm and 500mm from the ceiling.
• If you are not sure about the insulation in your mobile home, or if you notice the
walls and ceilings are either hot or cold, install alarm on an inside wall. For minimum
protection, install one alarm close to the bedrooms.
Note: Test your smoke alarm operation after mobile home vehicle has been in storage,
before each trip and at least once a week during use.
Avoid these Locations
• Do not locate your alarm in the garage - vehicles and workshop equipment can cause
fumes.
• Do not locate your alarm in front of forced air supply ducts used for heating and air
conditioning and other high air ow areas.
• Do not locate your alarm less than 500mm from the peak of an "A" frame type ceiling.
•
Do not locate your alarm in areas where temperatures may fall below 5°C or rise above
40°C, or in humidity higher than 90% as these conditions may reduce battery life.
6

Avoid these Locations
• Avoid dusty areas, dust particles may cause smoke alarm to false alarm or fail to alarm.
• Avoid very humid areas or near a bathroom or laundry, moisture can cause false alarm.
• Avoid insect-infested areas.
• Do not locate alarm within 0.9m of the following: the door to a kitchen, the door to a
bathroom containing a tub or shower, a ceiling or whole house ventilating fan, or
other high ow areas.
• Avoid locating near uorescent lights or other electrical equipment. Electronic
magnetic interferences or“noise”may cause nuisance alarms or chirping.
• Smoke alarms are not to be used with detector guards unless the combination (alarm
and guard) has been evaluated and found suitable for that purpose.
False Alarms
• This smoke alarm is designed to minimize false alarms. Smoking will not normally set
o the alarm unless smoke is blown directly into the alarm.
• Combustion particles from cooking may set o the alarm if the alarm is located close
to the kitchen cooking surface or appliance.
• Large quantities of combustion particles are generated from spills and over-boil.
• An alarm with a Hush Control device is preferable near a kitchen environment for this
reason.
Alarm Cleaning
To prevent false alarming caused by buildup of dust and insects, remove base plate
from alarm (see pg 8) and carefully vacuum all gaps and openings with the brush
attachment on your household vacuum cleaner. Repeat procedure every 6 months.

False Alarms
• Photoelectric type smoke alarms are less prone to false alarm near kitchen areas than
ionisation type smoke alarms.
• If the alarm does sound, check for re rst. If a re is discovered, escape quickly and
call the Fire Brigade. If no re is present, check to see if one of the reasons listed on
previous page may have activated the alarm.
How To Remove Smoke Alarm rom Base Plate
• Switch o mains power.
• Remove Tamper Locking Screw (if installed).
• Look for‘PUSH to OPEN‘ (Fig.3).
• Push rmly towards arrow until smoke alarm unhinges from base plate.
(Fig.3)
Installation
• This Smoke Alarm can only interconnect with other alarms of the same model.
Interconnection with other brands may cause damage or result in a shock or re risk
and void warranty.
8

Installation
• These smoke alarms must be installed by a registered electrician.
• Due to“noise”from electromagnetic interference, no more than 24 of these smoke
alarms may be interconnected.
• There are three terminals in the supply terminal block, marked A, S, N. It is important
that the alarm be wired correctly to ensure correct operation. Incorrect wiring to the
Smoke Alarm will damage the unit and void the warranty.
• A total maximum of 250 meters (820 feet) of wire can be used in interconnecting
smoke alarms.
• All nal sub-circuit conductors including the signal conductor must be a minimum
size of 1mm with 250V grade insulation.
• Interconnected Smoke Alarms must be connected to the same nal subcircuit.
• Do not use any wire that could later be confused with the normal house wires for the
interconnect wire. For example, green/yellow earth wire.
• Do not connect AC power wires to S interconnect terminal. These will damage smoke
alarms.
• Do not connect the S interconnect wire to any device, except the S interconnect
terminal of the smoke alarm. Otherwise, the smoke alarm will be damaged.
• Smoke alarms should be interconnected only within the connes of a single family
living unit. If smoke alarms are interconnected between dierent units, there may be
excessive nuisance alarms. Residents may not be aware that smoke alarms are being
tested or that it is a nuisance alarm caused by cooking etc.

Installation
• When interconnected, all Smoke Alarms will sound upon activation.
• Warning: This alarm cannot be operated from power derived from a square wave,
modied square wave or modied sine wave inverter. These type of inverters are
sometimes used to supply power to the structure in o grid installations, such as
solar or wind derived power sources. These power sources produce high peak
voltages that will damage the alarm.
• Orca recommend that the smoke alarms are installed on their own subcircuit to avoid
false alarms and nuisance chirping that may be caused by electromagnetic
interferences from other electrical equipment.
Mounting Instructions
• Separate Smoke Alarm from mounting base by sliding cover o.
• Connect supply cable to terminal block and x terminal cover.

Battery Installation, Replacement & Test
Battery Installation
The smoke alarm uses one 9V battery to automatically provide back-up power to the
alarm if AC power fails. The battery will operate the alarm for approximately one to three
months with AC power o.
The smoke alarm has a low battery indicator that will cause the unit to chirp and ash the
Red LED at approximately 33 second intervals for a minimum of 30 days. Missing battery
with main power connected will cause the unit to chirp and ash the Red LED at
approximately 33 second intervals.
Replace battery when chirping occurs.To ensure proper operation, the battery should be
replaced once a year.
To replace battery, remove alarm from mounting base (see section 6.2) and remove the
battery from compartment.Replace the old battery with a new one.
Use only the following 9 volt batteries for smoke alarm replacement.
Alkaline Type: ENERGIZER 522, DURACELL MN1604,
MX1604
Carbon Zinc Type: Gold Peak 1604E.
These batteries can be purchased at your local retail
outlet or supermarket.
Caution: Use only specied batteries. Use of dierent
batteries may have a detrimental eect on operation or
may cause the batteries to explode resulting in injury or
re.
16

Battery Installation, Replacement & Test
• Use only batteries specied on the label.
• Fold Red Battery Lever down into compartment with fresh replacement battery. If the
Red Battery Lever is not held down in the battery compartment by the battery, the
smoke alarm will not close and will not be operational.
Warning: Use of inferior batteries or incorrect types may cause a malfunction of the Alarm.
When replacing the battery and on reconnection of the detector to the base plate, make sure
that the detector is fully connected and flush with the base plate. Verify that the Green LE is
ON after reinstalling the alarm on the base plate.
Battery Test
• Switch o mains power. The Green LED on the smoke alarm will be OFF.
• Test alarm by pressing the Test Button for a few seconds. This should sound the alarm.
• If the battery module has a fault, the alarm will chirp every 33 seconds.
• Watch the Red LED for about 33 seconds. It should ash at least once.
• Switch on mains power only when smoke alarm passes the above tests. The Green
LED on the smoke alarm will come ON.
Note: Weekly testing is recommended!

Repairs & Services
• If the smoke alarm is defective in any way, do not tamper with the unit. Return the
unit to your supplier (See warranty for instructions on in-warranty returns). There will
be a service charge for repairing units out of warranty.
Good Sa ety Habits
The use of this product should not be seen as a substitute for basic safety precaution in
the prevention of FIRE.
There are situations where a smoke alarm may not be eective to protect against re:
• smoking in bed;
• leaving children home alone;
• cleaning with ammable liquids, such as petrol.
The Limitations o Smoke Alarms
• Smoke alarms are devices that can provide early warning of possible developing res
at a reasonable cost.
• Smoke alarms have certain limitations. For battery powered smoke alarms, the
battery must be in good condition and installed properly.
• AC powered alarms will not operate if AC power has been cut o, such as by an
electrical fault, open fuse or circuit-breaker, or re. However, the battery back-up will
activate the alarm if in good working order.
18

The Limitations o Smoke Alarms
• Smoke alarms must be tested regularly to ensure that the batteries and alarm circuit
are in good operating condition.
• Smoke alarms cannot provide an alarm if smoke does not reach the alarm. Therefore,
smoke alarm may not sense res starting in chimneys, walls, on roofs, on the other
side of a closed door, or on a dierent oor.
• If the alarm is located outside the bedrooms, or on a dierent oor, it may not wake
up a sound sleeper. A smoke alarm in the bedroom, therefore, is recommended.
• Smoke alarms have been signicant in saving lives in many parts of the world. Hence,
the use of this product does not substitute for basic prevention and total protection.
• Although smoke alarms can help save lives by providing early warning of a re, they
are not a substitute for an insurance policy.
• This smoke alarm alone will not alert the hearing impaired. Use special purpose
smoke alarm with lights or vibrating devices, for those hard of hearing.
• Heat alarms are available to oer greater security when used with smoke alarms.
• Life safety from re in residential occupancies is based on early notication to
occupants of the need to escape, followed by appropriate egress actions by
occupants. Fire warning systems for dwelling units are capable of protecting about
half of the population in potentially fatal res. Victims are often intimate with the re,
too old, young, or physically, mentally impaired that they cannot escape even when
warned early that escape should be possible. For these people, other strategies such
as protection-in-place or assisted escape or rescue are necessary.
19

Develop & Practice a Plan o Escape
Basic Escape Plan:
• Make a oor plan indicating all doors and windows and at least two escape routes
from each room. Second storey windows may need a rope or chain ladder.
• Have a family meeting and discuss your escape plan, showing everyone what to do in
case of re.
• Determine a place outside your home where all of you can meet, if a re occurs.
• Familiarize everyone with the sound of the smoke alarm and practice leaving your
home when they hear it.
• Practice a re drill at least every six months including drills at nights. Practice allows
you to test your plan before an emergency. You may not be able to reach your
children. It is important that they know what to do!
• Install and maintain re extinguishers on every level of the home and in the kitchen,
basement and garage. Know how to use a re extinguisher prior to an emergency.
• Current studies have shown smoke alarms may not awaken all sleeping individuals,
and that it is the responsibility of individuals in the household that are capable of
assisting others to provide assistance to those who may not be awakened by the
alarm sound, or to those who may be incapable of safely evacuating the area
unassisted.
