PGPx976 D-309558 Rev. 00
Location and positioning For minimum protection, follow these guidelines:
• Install a smoke detector on each story.
• Install a smoke detector in each sleeping area.
• Install a smoke detector within every 6.4 m (21 ft) of hallways and rooms.
• Install a smoke detector within 3 m (10 ft) of all bedroom doors.
• Install a smoke detector where all detectors are interconnected if the interconnect feature is enabled on your
control panel.
For increased protection, in addition to minimum protection, follow these guidelines:
• Install smoke detectors in every room, except kitchens and bathrooms.
• Install heat detectors in kitchens and garages within 5.3 m (17 ft) of potential fire sources.
Important:
Install smoke detectors in any bedrooms where fires might occur, for example, where there is an
electrical appliance in use or where the occupant is a smoker.
Important:
Install smoke detectors in any bedrooms where the occupant is elderly, sick, or very young and is
unable to respond to a fire that starts in their room.
Smoke detectors
Sufficient smoke must enter your smoke detector before an alarm occurs.
Install your smoke detector within 6.4 m (21 ft) of a potential fire to respond quickly. Install smoke detectors
where they can be heard throughout the property. A single smoke detector gives some protection if it is correctly
installed. Most homes require two or more smoke detectors, that are preferably interconnected, to ensure that
they give a reliable early warning.
Install your first smoke detector between the sleeping area and the most likely sources of fire, no more than 6.4 m
(21ft) from the door to any room where a fire may start and block your escape from the house.
National Fire Protection Association required protection
Where required by applicable laws, codes, or standards for the occupancy in the building, install approved single
and multiple station smoke detectors in the following areas:
1. In all bedrooms and guest rooms
2. Outside each separate sleeping area within 6.4 m (21 ft) of any door to a sleeping room
3. On every level of a dwelling unit, including basements
4. On every level of a residential board and care occupancy, including basement, and excluding crawl spaces and
unfinished attics
5. In the living areas of a guest suite
6. In the living areas of a residential board and care occupancy
The required number of smoke detectors might not provide reliable early warning protection for those areas
separated by a door. Consider the use of additional smoke detectors for those areas for increased protection.
The additional areas include the basement, bedrooms, dining room, furnace room, utility room, and hallways not
protected by the required smoke detectors. The installation of smoke detectors in finished or unfinished kitchens,
attics, or garages is not normally recommended. These locations can experience conditions that can result in
improper operation.
Important:
Specific requirements for smoke detector installation can vary. Check with your local fire
department for current requirements in your area. Consult National Fire Alarm Code NFPA 72 and CAN/ULC-
S524 or other department for current requirements in your area. Consult National Fire Alarm Code NFPA 72
or other appropriate national standards for installation recommendations. Smoke detectors must always be
installed in USA in accordance with Chapter 29 of NFPA 72, the National Fire Alarm Code: 29.5.1.1 installed in
USA in accordance with Chapter 29 of NFPA 72, the National Fire Alarm Code: 29.5.1.1.

Location and positioning Multistory dwellings
If your home has more than one floor, install at least one detector on each level. Interconnect the detectors if the
feature is present on your control panel to give sufficient warning throughout the property. If the interconnect
feature is enabled, refer to the control panel manual for more information.
Important:
Locate heat detectors in rooms adjoining escape routes, for example, kitchens, garages, and
boiler houses where smoke detectors are unsuitable.
Single story dwellings
If the premises is one story, install your first smoke detector in a corridor or hallway between the sleeping and
living areas. Install it as near to the living area as possible, but make sure that it can be heard in the bedrooms.
In houses with more than one sleeping area, install smoke detectors between each sleeping area and the living
area.
Note:
Install heat detectors in the kitchen and garage.
Enrolling your device

PGPx976 D-309558 Rev. 00
Installation instructions for RF equipment
The maximum separation (range) of the detector from the compatible receiver/control panel combination (free
space) is around
12
0 meters. However, this specified range is for comparative purposes only and is not
applicablewhen the equipment is installed in a typical home. The range of the RF equipment is greatly impacted
(reduced)by the building construction or any metallic bodies that are on the path of communication and are
not visible onthe outside. The proper location of the RF equipment is determined by strong signal strength as
indicated in thismanual. Upon completion of installation the system operation shall be tested as instructed in
this manual. Figure 3: Tamper proofing your detector
3. If necessary, use a No.2 or No.4 self tapping screw to firmly lock the detector and the mounting plate
together. The detector does not include a self tapping screw. Use a self tapping screw with the following
dimensions: Diameter = 2 mm to 3 mm (1/8 in.). Length = 6mm to 8mm (1/4 in.)
4. Attach the detector to the mounting plate. Line up the screw on the “U” shaped recessed area and screw in
firmly.
5. To remove the detector from the ceiling, remove the screw first, and then twist off anticlockwise.
Checking your detectors work
To check that the installed detectors work, complete the following steps:
1. Sound the detectors in their intended locations, check that you can hear the detector in each room with the
door closed, above the sound of any TV or audio systems.
2. Set the TV and audio systems to a reasonably loud conversation level. If you cannot hear the detector over
the sound of the TV or audio system, it will not wake house occupants. Use the interconnect feature on your
panel to ensure that the detector is heard throughout the property.
Mounting your detector
Mount your detector on a ceiling or a wall. You can mount a detector on a sloping ceiling if required.
Do not place smoke detectors in any of the following areas:
• Bathrooms, kitchens, shower rooms, garages or other rooms where smoke detectors are triggered by steam,
condensation, normal smoke, or fumes. Keep at least 6 m (20 ft) away from sources of normal smoke and
fumes.
• Very dusty or dirty areas as dust buildup in the chamber can affect performance. It can also block the insect
screen mesh and prevent smoke from entering the smoke detector chamber.
• In insect infested areas. Small insects in the smoke detector chamber can cause intermittent alarms.
• Places where the normal temperature can exceed 100°F (38.7°C) or go below 40°F (4.4°C), for example attics,
furnace rooms, directly above ovens or kettles, as the steam could cause nuisance alarms.
• Near a decorative object, door, light fitting, or window molding that prevents smoke entering the detector.
• Surfaces that are normally warmer or colder than the rest of the room, for example, attic hatches. Temperature
differences might stop smoke reaching the detector.
• Next to or directly above heaters or air conditioning vents, windows, and wall vents that can change the
direction of airflow.
• In very high or awkward areas, for example, over stairwells where it is difficult to reach the detector for testing,
silencing, or battery replacement.
Note:
Locate the detector at least 1 m (39 in.) from dimmer controlled lights and wiring as some dimmers can
cause interference.

PGPx976 D-309558 Rev. 00
Mounting your detector Note:
Locate the detector at least 1.5 m (59 in.) and route wiring at least 1 m away from fluorescent light
fittings as electrical noise and flickering may affect the unit.
Mounting your detector on the ceiling
Hot smoke rises and spreads out, so a central ceiling position is the recommended location to mount the detector.
Mount smoke detectors away from corners.
Important:
Keep smoke detectors at least 305 mm (12 in.) from walls and corners. Mount the detector at
least 305 mm (12 in.) from any light fitting or decorative object that might prevent smoke entering the smoke
detector.

Important:
Before you mount the detector permanently, conduct a walk test. Review the control panel
instructions to verify adequate signal strength and adjust the device location and orientation as necessary.
You can mount the detector on the ceiling or on the wall.
Mounting the detector on the wall
If it is not practical to mount the detector on the ceiling, mount the detector a wall. Consider wall mounting only
where close spaced beams or similar obstructions hinder ceiling mounting.
If you mount a detector on the wall, ensure that:
1. The top of the detection element is between 150 mm (6 in.) and 305 mm (12 in.) below the ceiling.

Mounting your detector 2. The bottom of the detection element is above the level of any door openings.
Important:
It is the responsibility of the installer to determine if the presence of asbestos in the ceiling
material makes the ceiling an impractical location to mount the device.
Mounting your detector on a sloping ceiling
If you want to mount a smoke detector on a sloping or peaked ceiling, install it within 610 mm (24 in.) of the peak
when the space is measured vertically. If this height is less than 610 mm (24 in.), consider the ceiling flat.

Fire safety information
When you use household protective devices, follow basic safety precautions.
• Rehearse emergency escape plans so everyone in the house is aware of what to do when the detector sounds.
• Use the detector test button to familiarize your family with the detector sound and practice fire drills regularly
with all family members. Draw up a floor plan that shows at least 2 escape routes from each room in the house.
Teach children how to escape, open windows, and use roll up fire ladders and stools without adult help. Make
sure children know what to do if the detector goes off.
• Constant exposure to high or low temperatures or high humidity may reduce battery life.
• You can quickly silence nuisance alarms by fanning vigorously with a newspaper or similar to remove the
smoke. Alternatively, press
Test / Hush
.
• Do not attempt to remove, recharge, or burn the battery, as it may explode.
• If it is necessary to remove the battery for separate disposal, handle carefully to avoid eye damage or skin
irritation if the battery leaks or is corroded.
• To maintain sensitivity to smoke, do not paint or cover the detector in any manner; do not permit any
accumulation of cobwebs, dust, or grease.
• If the detector is damaged in any way or does not function correctly, do not attempt to repair it. See Servicing
your detector
.
• This detector is intended only for residential premises.
• This detector is not a portable product. It must be mounted.
• Smoke detectors are not a substitute for insurance. The supplier or manufacturer is not your insurer.

PGPx976 D-309558 Rev. 00
Mounting your detector • Store petrol and other flammable materials in proper containers.
• Discard oily or flammable rags.
• Always use a metal fireplace screen and have chimneys cleaned regularly.
• Replace worn or damaged sockets, switches, home wiring, and cracked or frayed electrical cords and plugs.
• Do not overload electrical circuits.
• Keep matches away from children.
• Never smoke in bed. In rooms where you do smoke, always check under cushions for smouldering cigarettes
and ashes. Ensure all electrical appliances and tools have a recognized approval label.
• Smoke detectors are not to be used with detector guards unless the combination has been evaluated and
found suitable for that purpose.
• This device cannot protect everyone at all times. It may not protect against the three most common causes of
fatal fires:
a. Smoking in bed
b. Leaving children at home alone
c. Cleaning with flammable liquids, such as petrol
Planning your escape route
Use the following guidelines when you plan your escape route.
1. Check room doors for heat or smoke. Do not open a hot door. Use an alternate escape route. Close doors
behind you as you leave.
2. If smoke is heavy, crawl out, staying close to floor. Take short breaths, if possible, through a wet cloth or hold
your breath. More people die from smoke inhalation than from flames.
3. Get out as fast as you can. Do not stop to pack. Have a prearranged meeting place outside for all family
members. Check everybody is there.
4. Call the fire brigade from a neighbor’s house or mobile phone. Remember to give your name and address.
5. Never reenter a burning house.

PGPx976 D-309558 Rev. 00
Planning your escape route Limitations of smoke detectors
While smoke detectors are extremely effective, independent authorities have stated that they may be ineffective in
some circumstances. There are a number of reasons for this as follows:
• Smoke detectors do not work if the batteries are depleted or if they are not connected. Replace the batteries if
necessary. Check the replace by date on the side of the detector.
• Smoke detectors do not detect fire if sufficient smoke does not reach the detector. If the fire is on another
floor, behind a closed door, in a chimney, in a wall cavity, or if the prevailing air draughts carry the smoke or
heat away, smoke may not reach the detector. Install smoke detectors on both sides of closed doors and install
more than one detector.
• The smoke detectors may not be heard.
• A smoke detector may not wake a person who has taken drugs or alcohol.
• The detectors may not detect every type of fire to give sufficient early warning. They are particularly ineffective
with: fires caused by smoking in bed, escaping gas, violent explosions, poor storage of flammable rags and
liquids, for example, petrol, paint, spirits, overloaded electrical circuits, arson, children playing with matches.
• Current studies show smoke detectors may not wake 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 are not be
woken by the detector sound, or to those who may be incapable of safely evacuating the area unassisted.
Limitations of heat detectors
There are various situations where a heat detector is not effective as follows:
• Fires where the victim is close to a flaming initiated fire, for example, when a person’s clothes catch fire while
cooking.
• Fires where the heat does not reach the heat detector due to a closed door or other obstruction.
• Incendiary fires where the fire grows so rapidly that an occupant’s exit is blocked even with correctly located
heat detectors.

Detector indicator definitions
Normal Operation - Power Up
When the device powers up, the orange radio LED lights up for 1 second, indicating the device is starting and
performing self tests. After a successful self test that indicates radio connection to the detector, the green radio led
blinks for 2 seconds. If the device does not connect to the detector , the red radio led blinks continuously.
Normal operation - Standby
In standby mode, there are no active visible or audible indications that can be intrusive to the householder. To
confirm that the detector is operational, perform a weekly button test.
Normal operation - Weekly button test
Press and hold the test button and verify that the red LED flashes rapidly and the detector ramps up to full sound.
Normal operation - sensing fire
As soon as the detector senses smoke, it goes into alarm (along with any interconnected detectors). The alarm LED
on the detector sensing smoke flashes rapidly to indicate this is the detector sensing smoke / fire. Evacuate the
building.
Normal operation - silence false alarm
Occasionally smoke detectors are activated by events other than fire, for exmaple, dust, insects, and cooking
fumes. When you are sure the alarm is caused by a nuisance detector, press
Test/Hush
to silence the detector for
10 minutes. The alarm LED then flashes every 8 seconds for 10 minutes.
Normal operation - false alarm in an interconnected system
In the case of a real fire, evacuate the dwelling. If the system responds to a recurring false alarm, identify the
detector that causes the false alarm so you can clean or replace the detector. The detector that causes the false
alarm is identified by a rapidly flashing alarm LED. See Normal operation - silence false alarm .

PGPx976 D-309558 Rev. 00
Detector indicator definitions Fault condition - low battery
The detector emits a short beep and the alarm LED flashes when the battery is low. Check the date on the side
of the detector to identify when the battery is due to be replaced. When electronic self testing indicates that the
battery is low, the detector beeps and the alarm LED flashes at the same time every 48 seconds to warn the user.
Replace the battery or batteries as soon as possible. See
Replacing batteries
.
Fault condition - contaminated chamber
If the detector sounds without any apparent smoke present, press
Test/Hush
to silence the detector for 10
minutes. If the detector sounds again, it may be contaminated. Press
Test/Hush
again, within 4 minutes of the
detector sounding. If the detector sounds for a third time, the detector is excessively contaminated and you must
replace it. If it is not convenient to replace it immediately, press
Test/Hush
within 4 minutes of it going into alarm
for the third time. This silences the detector for 8 hours.
Note:
The detector then beeps twice every 10 minutes to remind you it is disabled. If the contamination
clears, the detector returns to normal operation.
Fault condition - faulty smoke chamber
If the smoke sensing chamber becomes defective, the detector beeps twice and the alarm LED flashes every 48
seconds. You must replace the detector. If it is not convenient to replace it immediately, press
Test/Hush
to silence
the alarm and stop the alarm LED flashing for 12 hours. This can be repeated as required.
Testing, maintenance, and power supply monitoring
Your detector is a life saving device. Test the detector immediately after installation and at least once a year.
If you hold
Test/Hush
for more than 7 seconds, a red radio LED blinks for 2 seconds and a fire alarm occurs. This
alarm is sent to the panel, so you can test the entire reporting path.
Note:
Notify the central station when the smoke detector is undergoing tests so they do not dispatch
authorities.
After you enroll the device, verify adequate signal strength by conducting a sensor test with the device in the
mounting location. See the control panel user manual for more information. Adjust the device location and
orientation as necessary.
Manually testing your detectors
Test your detectors after they are installed and then at least weekly to ensure the units are working. To manually
test your detectors, complete the following steps:
1. Press and hold
Test/Hush
until the detector sounds and the red light flashes. The detector stops sounding
shortly after you release the button.
2. Repeat this procedure for all other detectors in the system.
Do not test with a flame. This can set fire to the detector and damage the house. Do not test with smoke as
the results can be misleading unless you use specialist equipment.
Using the
Test/Hush button
The smoke detectors have a Test/Hush button to control nuisance or false alarms.

PGPx976 D-309558 Rev. 00
Testing, maintenance, and power supply monitoring When the detector sounds, if there is no sign of smoke or noise to indicate that there is a fire, assume that it is due
to an actual fire. Evacuate the dwelling immediately. If there are frequent false alarms, relocate the smoke detector
away from the source of the fumes.
1. To cancel a false alarm from a smoke detector, press
Test/Hush
. The smoke detector switches to a reduced
sensitivity condition.
The smoke detectors are silenced for a period of approximately 10 minutes. The alarm LED on the cover of the
smoke detector flashes every 8 seconds to indicate that the unit is silenced.
2. The smoke detector resets to normal sensitivity at the end of the 10 minute silence period. If additional time is
required, push
Test/Hush
again.
3. If the kitchen usage or layout causes too many nuisance alarms, relocate the smoke detector further away
where it is less affected by cooking fumes.
Note:
Use a heat detector in the kitchen area to avoid nuisance alarms.
Replacing batteries
When the device battery power is low and replacement is necessary, the smoke detector beeps and the yellow light
flashes at the same time once every 48 seconds for at least 30 days. Replace the battery, ensuring the orientation is
correct, as soon as possible.
When you replace the battery,ensuring the orientation is correct, press
Test/Hush

WARNING:
Constant exposure to high or low temperatures or high humidity may reduce battery life. Use
only Panasonic CR123A Batteries. If you use a different battery, it may have a detrimental effect on detector
operation. The detectors are intended for use at ordinary temperatures where anticipated temperatures are
not expected to exceed 100°C (212°F). Prolonged periods of alarm will also reduce battery life. The battery
used in this device may present a fire or chemical burn hazard if mistreated.
Cleaning your detector
Clean your detector once every year. Use a soft bristle brush or the brush attachment on your vacuum cleaner to
remove dust and cobwebs from the side slots where the smoke enters. To clean the cover, wipe with a damp cloth
and dry thoroughly.
WARNING:
Do not paint your detector.
Other than maintenance and cleaning, do not perform any other servicing of this product. Repairs must be
performed by the manufacturer.
Cleaning the detector chamber
A suitably trained person should clean or replace the chamber cover. To clean the detector chamber, complete the
following steps:
1. Remove the detector from the mounting plate and remove the battery.
2. With a flat screwdriver unclasp the three cover clip points and remove the cover.
3. Hold the thermistor PCB and pull the pins out of the sockets to unplug the thermistor.
4. To remove the chamber top, turn the chamber anticlockwise approximately 15°.
5. Use a soft bristled brush to remove dust and dirt form the chamber base.

Testing, maintenance, and power supply monitoring 8. Place the cover back on the detector, ensuring the thermistor protrudes out over the cover.
9. Replace the battery and reattach to the mounting plate.
10. Press the
Test/Hush
button to ensure the detector is working correctly.
Note:
If the device is tampered with for cleaning, it will enter diagnostic mode. See Performing a
diagnostic test
for more details.
Smoke detector automatic self test
The smoke chamber in the smoke detectors automatically tests itself every 16 seconds. If the chamber is degraded
the detector beeps twice every 48 seconds and 2 yellow LEDs flash. If this happens, clean the unit. If the beeping
persists and the beep does not coincide with a yellow light flash, return the unit for service. See Servicing your
detector
.
Dust and insect contamination
All smoke detectors and particularly the optical or photoelectric detectors are prone to dust and insect ingress that
can cause false alarms.
The latest design, materials, and manufacturing techniques are used in the construction of the detectors to
minimize the effects of contamination. It is impossible to completely eliminate the effect of dust and insect
contamination. To prolong the life of the detector, ensure that it is kept clean so that excess dust does not build up.
Any insects or cobwebs near the smoke detector should be removed.
In certain circumstances, even with regular cleaning, contamination can build up in the smoke sensing chamber
which causes the detector to sound. If this happens, return the smoke detector for servicing or replacement. See
Servicing your detector
.
Important:
Contamination is not covered by the guarantee and you will be charged for all such servicing
work.
End of life
It is recommended to replace the entire detector if the unit was installed more than 10 years ago. Check the expiry
date on the side of the detector.
Before the detector is discarded, remove from the mounting plate and disconnect the batteries.
WARNING:
Do not dispose of your detector in a fire.
Dispose of your detector in a safe and environmentally sound manner at your local recycle center. Contact your
local authority for further advice.

Troubleshooting
For guidance around investigating problems with your detector, see the following troubleshooting topics to
restore your detectors to normal operation:
The detector does not sound when you press Test/Hush
1. Check how old the detector is. See the
Replace by
label on side of detector.
2. If necessary, replace the battery or batteries with Panasonic CR123A batteries.
Detectors sound for no apparent reason
1. If you enroll your detector and the interconnect feature is enabled, refer to your control panel to detect which
device is causing the alarm.
2. Check for fumes or steam from the kitchen or bathroom. Paint and other fumes cause nuisance detectors.
3. Check for any sign of contamination such as cobwebs or dust. See Cleaning your detector
.
4. Press
Test/Hush
on the smoke detector causing the alarm. You can identify the detector in alarm by the alarm
LED flashing rapidly. This silences the smoke detector and all other interconnected detectors in the system for
10 minutes.
