Special compliance considerations, continued
It is not a suitable substitute for complete fire detection systems in ware-
houses, industrial facilities, commercial buildings, and special-purpose non-
residential buildings which require special fire detection and alarm systems.
Depending on the building regulations in your area, this Smoke Alarm may
be used to provide additional protection in these facilities.
The following information applies to all four building types below:
In new construction, most building regulations require the use of mains
(AC) or mains powered with integral standby supply (AC/DC) Smoke
Alarms only. In existing construction, mains powered (AC), mains powered
with integral standby supply (AC/DC), or battery (DC) powered Smoke
Alarms can be used as specified by local building regulations. Refer to
British Standard BS 5839 Part 6 and BS 5588 Part 1, local buildings regula-
tions, or consult your Fire Brigade for detailed fire protection requirements
in buildings not defined as "dwellings."
1. Single-family residence: Single family home. It is recommended Smoke
Alarms be installed in all circulation spaces (normally hallways and staircases)
that form part of escape routes, on every level, in all rooms and areas that
present a high fire risk and between the sleeping area(s) and the most likely
sources of fire (living room and kitchen).
2. Multi-family or mixed occupant residence: Blocks of flats.This Smoke
Alarm is suitable for use in individual flats, provided a primary fire detec-
tion system already exists to meet fire detection requirements in common
areas like foyers, hallways, corridors, or porches. Using this Smoke Alarm in
common areas may not provide sufficient warning to all residents or meet
local fire protection by-laws/regulations.
3. Institutions: Hospitals, day care facilities, long-term health care facilities.
This Smoke Alarm may be suitable for use in individual patient sleeping/
resident rooms, provided a primary fire detection system already exists to
meet fire detection requirements in common areas like foyers, hallways,
corridors, or porches. Using this Smoke Alarm in common areas may not
provide sufficient warning to all residents or meet local fire protection
by-laws/regulations.
4. Hotels and motels: Also hostels, inns, boarding houses and sheltered
housing.This Smoke Alarm may be suitable for use inside individual sleeping/
resident rooms, provided a primary fire detection system already exists to
meet fire detection requirements in common areas like foyers, hallways,
corridors, or porches. Using this Smoke Alarm in common areas may not
provide sufficient warning to all residents or meet local fire protection
by-laws/regulations.
General limitations of smoke/CO alarms
This Smoke/CO Alarm is intended for residential use. It is not intended
for use in industrial applications where Occupational Safety and Health
Administration (OSHA) requirements for Carbon Monoxide Alarms must
be met.The Smoke Alarm portion of this device is not intended to alert
hearing impaired residents. Special purpose Smoke Alarms should be
installed for hearing impaired residents (CO Alarms are not yet available
for the hearing impaired).
Smoke/CO Alarms may not waken all individuals. Practice the escape plan
at least twice a year, making sure that everyone is involved – from kids to
grandparents. Allow children to master fire escape planning and practice
before holding a fire drill at night when they are sleeping. If children or
others do not readily waken to the sound of the Smoke/CO Alarm, or if
there are infants or family members with mobility limitations, make sure
that someone is assigned to assist them in fire drill and in the event of
an emergency. It is recommended that you hold a fire drill while family
members are sleeping in order to determine their response to the sound
of the Smoke/CO Alarm while sleeping and to determine whether they
may need assistance in the event of an emergency.
Smoke/CO Alarms cannot work without power. Battery operated units
cannot work if the batteries are missing, disconnected or dead, if the wrong
type of batteries are used, or if the batteries are not installed correctly.
AC units cannot work if the AC power is cut off for any reason (open fuse
or circuit breaker, failure along an electrical main or at a power station,
electrical fire that burns the electrical wires, etc.). If you are concerned
about the limitations of battery or AC power, install both types of units.
Smoke/CO Alarms cannot sense smoke or CO that does not reach the
sensors. Smoke or CO from fires in chimneys or walls, on roofs, or on the
other side of closed doors may not reach the sensing chamber and set off
the alarm.That is why one unit should be installed inside each bedroom or
sleeping area—especially if bedroom or sleeping area doors are closed at
night—and in the hallway between them.
Smoke/CO Alarms may not detect smoke or CO on another floor or area
of the home. For example, a stand-alone unit on the second floor may not

units may provide earlier warning than stand-alone units since all units
alarm when one detects smoke or CO.
Smoke/CO Alarms may not be heard.Though the alarm horn in this unit
meets or exceeds current Standards, it may not be heard if: 1) the unit is
located outside a closed or partially closed door, 2) residents recently
consumed alcohol or drugs, 3) the alarm is drowned out by noise from
stereo,TV, traffic, air conditioner or other appliances, 4) residents are hear-
ing impaired or sound sleepers. Special purpose units, like those with visual
provided the batteries
and audible alarms, etc. should be installed for hearing impaired residents.
The Alarm may not have time to alarm before the fire itself causes damage,
injury, or death, since smoke from some fires may not reach the unit
immediately. Examples of this include children playing with matches, fires
caused by violent explosions resulting from escaping gas or fires where the
victim is in contact with burning materials such as a mattress.
Smoke/CO Alarms are not foolproof. Like any electronic device, Smoke/CO
Alarms are made of components that can wear out or fail at any time.
You must test the unit weekly to ensure your continued protection.
Smoke/CO Alarms cannot prevent or extinguish fires.They are not a
substitute for property or life insurance.
Smoke/CO Alarms have a limited life.The unit should be replaced
immediately if it is not operating properly. Smoke alarms are not to be
used with detector guards unless the combination has been evaluated and
found suitable for that purpose. Write the purchase date on the user's

•
If the Smoke/CO Alarm becomes contaminated by excessive dirt, dust
and/or grime, and cannot be cleaned to avoid unwanted alarms, replace
the unit immediately.
•
Relocate the unit if it sounds frequent unwanted alarms. See "Where
This Alarm Should Not Be Installed" for details.
Choosing a replacement battery:
Your smoke/CO Alarm requires two AA Energizer E91 batteries. These
are commonly available at local retail stores.
Actual battery service life depends on the Smoke/CO Alarm and the
environment in which it is installed. All the batteries specified above are
acceptable replacement batteries for this unit. Regardless of the manufactur-
er's suggested battery life, you MUST replace the battery immediately once
the unit starts "chirping" (the "low battery warning").
To replace the batteries (without removing
Alarm from the ceiling or wall):
1. Open the battery compartment.
2. Press tabs A and B as shown in the diagram
and remove each battery.
3. Insert the new batteries, making sure
they snap completely into the battery

compartment. Match the terminals on
the ends of the batteries with the terminals
on the unit.
4. Close the battery compartment, and then
test the unit by pressing the Test/Silence
button.

"ALARM-MOVE TO FRESH AIR"
If you hear the alarm horn sound 4 beeps, pause, 4 beeps, pause and the
RED CO light is flashing, move everyone to a source of fresh air.
Actuation of your CO Alarm indicates the presence of carbon monoxide
(CO) which can kill you. In other words, when your CO Alarm sounds,
you must not ignore it!
If the CO alarm signal sounds:
1. Operate the Test/Silence button.
2. Call your emergency services or Fire Brigade (like 999 in the UK or
112 in Europe).Write down the number of your local emergency
service here:
_________________________________________________________
3. Immediately move to fresh air—outdoors or by an open door or win-
dow. Do a head count to check that all persons are accounted for. Do
not re-enter the premises, or move away from the open door or win-
dow until the emergency services responder has arrived, the premises
have been aired out, and your CO Alarm remains in its normal condition.
4. After following steps 1-3, if your CO Alarm reactivates within a 24-hour
period, repeat steps 1-3 and call a qualified appliance technician to
investigate for sources of CO from fuel-burning equipment and appli-
ances, and inspect for proper operation of this equipment. If problems
are identified during this inspection have the equipment serviced
immediately. Note any combustion equipment not inspected by the
technician, and consult the manufacturers' instructions, or contact the
manufacturers directly, for more information about CO safety and this
equipment. Make sure that motor vehicles are not, and have not, been
operating in an attached garage or adjacent to the residence.Write
down the number of a qualified appliance technician here:

If the smoke alarm sounds
Responding to an alarm
If you hear the alarm horn sound 3 beeps, pause, 3 beeps, pause and
the RED SMOKE light is flashing, smoke has been detected.
Evacuate everyone from the building.
•
If the unit alarms and you are not testing the unit, it is warning you
of a potentially dangerous situation that requires your immediate
attention. NEVER ignore any alarm. Ignoring the alarm may result in
injury or death.
•
Never remove the batteries from a battery operated Smoke/CO
Alarm to stop an unwanted alarm (caused by cooking smoke, etc.).
Removing batteries disables the alarm so it cannot sense smoke,
and removes your protection. Instead open a window or fan the
smoke away from the unit.The alarm will reset automatically.
•
If the unit alarms get everyone out of the house immediately.
What to do in case of fire
• Don't panic; stay calm. Follow your family escape plan.
• Get out of the house as quickly as possible. Don't stop to get
dressed or collect anything.
• Feel doors with the back of your hand before opening them.
If a door is cool, open it slowly. Don't open a hot door. Keep doors
and windows closed, unless you must escape through them.
• Cover your nose and mouth with a cloth (preferably damp).
Take short, shallow breaths.
• Meet at your planned meeting place outside your home,
and do a head count to make sure everybody got out safely.
• Call the Fire Brigade as soon as possible from outside.
Give your address, then your name.
• Never go back inside a burning building for any reason.
• Contact your Fire Brigade for ideas on making your home safer.
Alarms have various limitations. See "General Limitations of Smoke/CO
Alarms" for details.
Using the silence feature
Never remove the batteries to quiet an unwanted alarm. Removing the
batteries disables the alarm and removes your protection.
The Silence Feature is intended to temporarily silence the horn while you
identify and correct the problem. Do not use the Silence Feature in emer-
gency situations. It will not correct a CO problem or extinguish a fire.
To use the Silence Feature, press and hold the Test/Silence button on the
cover of the Smoke/CO Alarm for 3 seconds.
