FAMILY ESCAPE PLAN
According to National Fire Protection Association (NFPA), there often is very little time between
the detection of a fire and the time it becomes deadly. This interval can be as little as 2 minutes.
Planning and practicing for fire conditions with a focus on rapid exit from the residence are
important. Drills should be held so that all family members know the action to be taken.
Make a home escape plan. Draw a map of your home showing all doors and windows. Discuss
the plan with everyone in your home.
Know at least two ways out of every room, if possible. Make sure all doors and windows leading
outside open easily.
Have an outside meeting place (like a tree, light pole or mailbox) a safe distance from the home
where everyone should meet.
Practice your home fire drill at night and during the day with everyone in your home, twice a year.
Practice using different ways out.
Teach children how to escape on their own in case you can’t help them.
Close doors behind you as you leave.
IF THE DETECTOR SOUNDS
If the smoke detector sounds, get out and stay out. Never go back inside for people or pets.
If you have to escape through smoke, get low and go under the smoke to your way out.
Call the fire department from outside your home.

Detector status and indication
The Wireless Smoke Heat Detector contains a sounder which generates the ANSI S3.41 temporal 3
pattern in an alarm condition.
In alarm, a message is also sent to the control panel and the Detector’s ID is displayed at the
console. During an alarm condition, pressing the Detector’s hush button will silence the sounder (see
). The mounting base installation is simplified by the incorporation of features compatible for
both drywall fasteners (not supplied) and other methods.
Red and Green LEDs and a sounder on the Detector provide local visual and audible indication of
the Detector’s status as listed in Table 1.
During initial power-up the red LED will flash once followed by one flash of the yellow LED to indicate
that the Detector has been powered successfully and is now in standby mode.
After power-up has completed and the Detector is functioning normally, there will be no LED
As soon as the Detector senses smoke, it will go into Alarm. The red LED begins to
flash rapidly to indicate that this is the Detector sensing smoke / fire.
Silence False / Nuisance Alarm:
Occasionally Smoke Detectors can be activated by
phenomena other than fire, such as dust, insects, cooking smoke and shower steam. When the
Detector sounds and there is no sign of smoke or noise to indicate that there is a fire, it should be
assumed that it is due to an actual fire. The dwelling should be evacuated immediately, and the local
Fire Department should be contacted.
It is possible that cooking smoke, steam, etc., may be the source of nuisance alarms.
If there are frequent nuisance/false alarms, it may be necessary to re-locate the Smoke Detector
away from the source (cooking smoke, shower steam, etc.).
Once you are sure it is a nuisance alarm, press the large test button to silence the Detector for 10
minutes – the red LED will then flash every 8 seconds for 10 minutes.
Pressing the test button will make the unit less sensitive, but if a large amount of smoke / steam /
dust is observed the unit will remain in alarm.
Low Battery Detection:
The Wireless Smoke Heat Freeze Detector is powered by two CR123A
The Detector regularly checks for a low battery. If a low battery is detected, the transmitter sends a
low battery message to the control panel, which displays the Detector’s ID at low battery. In addition,
the yellow LED and the Detector’s sounder will chirp every 48 seconds until the batteries are
replaced. The batteries should be replaced when the chirps begin. Be sure to replace the batteries
with fresh ones.
BATTERY INSTALLATION AND REPLACEMENT
To replace the batteries:
Remove the Detector from its mounting base by twisting the Detector counterclockwise. Remove
and dispose of the batteries according to your local regulations.
To ensure proper power-down sequence, wait a minimum of 20 seconds before installing new
Install two new CR123A batteries (available from your local Panasonic dealer) in the battery
compartment. Follow the polarity diagram inside the compartment. If the batteries are incorrectly
inserted, please remove gently with a non-conductive tool and correctly reinsert.

THIS EQUIPMENT SHOULD BE INSTALLED IN ACCORDANCE WITH THE NATIONAL FIRE
PROTECTION ASSOCIATION’S STANDARD 72.
LIMITATION OF WIRELESS EQUIPMENT
When placing the wireless smoke Detectors, it is important to remember that they communicate with
the 2GIG panel over radio frequency (RF). This subjects the system to radio interference, which can be
caused by a variety of sources, such as other RF devices, construction materials, meta objects, or even
when placing sensors in close proximity to other appliances, electronic devices or electrical wiring.
The maximum separation range is over 700 ft line-of-sight between the panel and the smoke
Detector, which may be reduced by the factors stated above. To ensure the Detectors are installed in
areas that provide the best possible signal strength, please note the following illustration:
MOUNTING THE DETECTOR
These detector devices should only be installed by a competent engineer.
This device should not be used with a guard.
Once a suitable location is found, mount the Detector as follows:
Refer to the diagram below, and install the mounting base on the ceiling or on the wall (if local
ordinances permit) using screw locations as required. Use the two screws and anchors provided.
Maneuver the base so the screws are at the elbow of the screw slots and secure.
Fit the Detector inside the base by aligning it over the base as shown (Detector’s alignment
notch should be aligned with the mounting base tamper release tab and mark), then turn the
Detector in a clockwise direction until it clicks into place.
Test the Detector after completing the installation (as described in the TESTING THE DETECTOR
section of this manual) and refer to the control system’s instructions for additional information
concerning the use of wireless devices.
DO NOT attach the Detector to removable ceiling panels.
TESTING THE DETECTOR
Before testing, notify the central station that the Detector system is undergoing maintenance
in order to prevent unwanted alarms. Testing the Detector will activate an alarm and send a signal to
the panel. Also, the test function cannot be used if the Detector has a trouble condition.
Detectors must be tested after installation and following periodic maintenance.
Testing Detector Operation
This test checks the Detector’s sounder, LEDs, and transmitter.
The test button is located on the Detector housing.
Push and hold the test button until the Detector sounds and the red LED flashes (see
The Detector will stop sounding shortly after the button is released. The alarm panel will trigger
and into alarm. The sounder begins the temporal 3 pattern and the red LED blinks. The alarm
panel’s console should display the Detector’s name in alarm.
WARNING: Do not test with flame.
This can set fire to the Detector and damage the house. We do not recommend testing with smoke
as the results can be misleading unless special apparatus is used.
When you press the
, it simulates the effect of smoke in a Smoke Detector which it
could experience in a real fire.
A DETECTOR THAT FAILS TO ACTIVATE WITH ANY OF THESE TESTS SHOULD FIRST BE
CLEANED AS OUTLINED IN THIS MANUAL’S MAINTENANCE SECTION. IF THE DETECTOR STILL
FAILS TO ACTIVATE, RETURN FOR REPAIR.
TEST ONCE A WEEK.
WARNING! USE ONLY BATTERIES SPECIFIED. USE OF DIFFERENT BATTERIES MAY HAVE A
DETRIMENTAL EFFECT ON THE SMOKE DETECTOR.
The smoke chamber in the Smoke Detectors automatically tests itself every 16 seconds. If the
chamber is degraded, it will beep twice every 48 seconds with 2 yellow LED flashes at the same
time. If this happens clean the unit. If the beeping persists and the beep does not coincide with a
yellow light flash, contact your dealer for service.
Dust and Insect Contamination
All Smoke Detectors and particularly the optical (photoelectric) type are prone to dust and insect
ingress which can cause false alarms.
The latest design, materials and manufacturing techniques have been used to minimize the effects
of contamination. However, it is impossible to completely eliminate the effect of dust and insect
contamination, and therefore, to prolong the life of the Detector you must ensure that it is kept clean
so that excess dust does not build up. Any insects or cobwebs in the vicinity of the Smoke Detector
should be promptly removed.
Excessive dust may cause the unit to fault with 4 amber flashes every 48 seconds and 4 chirps with
4 flashes on test button.
In certain circumstances even with regular cleaning, contamination can build up in the smoke
sensing chamber causing the Detector to sound. If this happens contact your dealer for servicing or
Contamination is beyond our control, it is totally unpredictable and is considered normal wear and
tear. For this reason, contamination is not covered by the warranty.
YOUR DETECTOR SHOULD BE CLEANED AT LEAST ONCE A YEAR.
To clean your Detector, remove it from the mounting base. You can clean the interior of your
detector by using compressed air or vacuum cleaner hose and blowing or vacuuming through the
openings around the perimeter of the detector. The outside of the detector can be wiped with a
After cleaning, reinstall and test your detector by using the test button. If cleaning does not restore
the detector to normal operation the detector should be replaced.
WARNING: Do not paint your Detector.
Other than the maintenance and cleaning described in this manual, no other customer servicing of
this product is required. Repairs, when needed, must be performed by authorizes service personnel.
WARNING: PLEASE READ CAREFULLY AND THOROUGHLY
NFPA 72 states:
Fire-warning equipment for residential occupancies are capable of protecting
about half of the occupants in potentially fatal fires. Victims are often intimate with the fire, too
old or too young, or physically or mentally impaired such that they cannot escape even when
warned early enough that escape should be possible. For these people, other strategies such as
protection-in-place or assisted escape or rescue would be necessary.
A battery powered detector must have a battery of the specified type, in good condition and
Smoke detectors must be tested regularly to make sure the batteries and the alarm circuits are
in good operating condition.
Smoke detectors cannot provide an alarm if smoke does not reach the Detector. Therefore,
smoke detectors may not sense fires starting in chimneys, walls, on roofs, on the other side of a
closed door or on a different floor
If the detector is located outside the sleeping room or on a different floor, it may not wake up a
Studies have shown that smoke and heat 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 those who may
be incapable of safely evacuating the area unassisted.
The use of alcohol or drugs may also impair one’s ability to hear the smoke alarm. For maximum
protection, a smoke detector should be installed in each sleeping area on every level of a home.
Although smoke detectors can help save lives by providing an early warning of a fire, they
are not a substitute for an insurance policy. Home owners and renters should have adequate
insurance to protect their properties.
Reinstall the Detector onto the mounting base by turning the Detector clockwise until the mating
After the power-up sequence, the red LED will flash once followed by one flash of the yellow
LED to indicate that the Detector has been powered successfully and is now in standby mode.
If the batteries are not installed correctly, the Detector will not operate and the batteries may be
damaged. If the Detector does not power-up, check for correct batteries installation and for a
fully charged batteries.
Test the Detector (as described later).
CONSTANT EXPOSURES TO HIGH OR LOW TEMPERATURES OR HIGH HUMIDITY MAY REDUCE
The internal wireless transmitter must be programmed into the control panel.
Refer to the control panel’s instructions to program the receiver with the Detector’s serial number
(TX ID from the label).
Each of the Detector’s functions must be programmed into the panel.

RECOMMENDED LOCATIONS FOR SMOKE HEAT DETECTOR
According to National Fire Protection Association (NFPA) the major threat from fire in a dwelling unit
occurs at night when everyone is asleep. The principal threat to persons in sleeping areas comes
from fires in the remainder of the unit; therefore, a smoke Detector(s) is best located between the
bedroom areas and the rest of the unit. In units with only one bedroom area on one floor, the smoke
Detector(s) should be located as shown in
. In dwelling units with more than one bedroom
area or with bedrooms on more than one floor, more than one smoke Detector is required, as
In addition to smoke Detectors outside of the sleeping areas, the device should be installed on
each additional story of the dwelling unit, including the basement. These installations are shown in
. The living area smoke Detector should be installed in the living room or near the stairway
to the upper level, or in both locations. The basement smoke Detector should be installed in close
proximity to the stairway leading to the floor above. Where installed on an open-joisted ceiling, the
Detector should be placed on the bottom of the joists. The Detector should be positioned relative to
the stairway so as to intercept smoke coming from a fire in the basement before the smoke enters
Smoke Detectors are optional where a door is not provided between living room and recreation
The smoke from a fire generally rises to the ceiling, spreads out across the ceiling surface, and
begins to bank down from the ceiling. The corner where the ceiling and wall meet is an air space
into which the smoke could have difficulty penetrating. In most fires, this dead air space measures
about 0.1m (4in.) along the ceiling from the corner and about 0.1m (4in.) down the wall. Detectors
should not be placed in this dead air space, see
Where NOT to install the Detector:
Directly above a sink, cooker, stove or oven
Do not locate Detector within 10 feet (3m) of any cooking appliance. However, to reduce the
likelihood of incidental alarms due to cooking, the distance can be increased to a minimum of
20 feet (6m) where possible.
Next to a door or window that would be affected by drafts i.e. extractor fan or air vent outside
Do not install in any environment that does not comply with the Detector’s environmental
