Location and positioning
Introduction
Congratulations on purchasing your smoke alarm.You can easily install multiple alarms
throughout the property on escape routes, on each story, in corridors and in closed
rooms to give warning of re.The smoke alarm can be wirelessly connected to a supple-
mentary Visit receiver in order to provide an additional warning.
NATIONAL FIRE PROTECTION ASSOCIATION REQUIRED PROTECTION
Smoke detection. Where required by applicable laws, codes, or standards for the
specied occupancy, approved single- and multiple-station smoke alarms shall be
installed as follows:
1In all sleeping rooms. Exception: Smoke alarms shall not be required in sleeping rooms
in existing one- and two-family dwelling units.
2Outside of each separate sleeping area, in immediate vicinity of the sleeping rooms.
3On each level of the dwelling unit, including basements Exception: In existing one- and
two-family dwelling units, approved smoke alarms powered by batteries are permitted.
Are more smoke alarms desirable?
The required number of smoke alarms might not provide reliable early warning protec-
tion for those areas separated by a door from the areas protected by the required smoke
alarms. For this reason, it is recommended that the householder consider the use of
additional smoke alarms for those areas for increased protection.
87
The additional areas include the basement, bedrooms, dining room, furnace room, utility
room, and hallways not protected by the required smoke alarms
The installation of smoke alarms in kitchens, attics (nished or unnished), or garages
is not normally recommended, as these locations occasionally experience conditions
that can result in improper operation.
The equipment should be installed using wiring methods in accordance with the Na-
tional Fire Protection Association’s Standard 72, Chapter 11. (National Fire Protection
Association, Batterymarch Park, Quincy, MA 02269).
IMPORTANT!
Specic requirements for smoke alarm installation vary from state to state and from
region to region. Check with your local re department for current requirements in
your area.
SMOKE ALARM TRANSMITTER, BE1281
Sucient smoke must enter your smoke alarm before it will respond. Your smoke alarm
needs to be within 6.4 meters (21ft) of the re to respond quickly. Your smoke alarms
also need to be in positions where they can be heard throughout the property, so they
can wake you and your family in time for everyone to escape. A single smoke alarm
will give some protection if it is properly installed, but most homes will require two or
more to ensure that a reliable early warning is given. For recommended protection you
should put individual smoke alarms in all rooms where re is most likely to break out
(apart from the kitchen and bathroom).

Minimum protection level
- smoke alarm on each story
- in each sleeping area
- every 6.4 meters (21ft) of hallways and rooms
- within 3 meters (10ft) of all bedroom doors
Recommended protection level
(In addition to the above):
- smoke alarms in every room (except kitchens
and bathrooms)
- heat alarms located in kitchens, garages etc.
within 5.3 meters (17ft) of potential re sources
Your rst smoke alarm should be located between the sleeping area and the most likely
sources of re (living room for example), but it should not be more than 6.4 meters (21ft)
from the door to any room where a re may start and block your escape from the house.
Multi-story dwellings
If your home has more than one oor, at least one smoke alarm should be tted on each
level, see Figure 1. Preferably the units should be connected to a Visit receiver so as to
give an additional warning throughout the property.
Figure1 illustrates where smoke and heat alarms should be located in a typical two
story house. Note the spacings in “Protection Levels” which ensure the early detection
of re and that the warning will be heard.
Use heat alarms in rooms adjoining escape routes - kitchens, garages, boiler houses etc.
where smoke alarms are unsuitable.
Single story dwelling
If the premises are one story you should put your rst smoke alarm in a corridor or hallway
between the sleeping and living areas. Place it as near to the living area as possible, but
make sure that it can be heard loudly enough in the bedroom to wake someone. See
Figure 2 for placement example.
In houses with more than one sleeping area, smoke alarms should be placed between
each sleeping area and the living area and it is recommended that heat alarms should
be placed in the kitchen and garage.

Recommended protection
Fire authorities recommend you put individual smoke alarms in or near all rooms where
re is most likely to break out (apart from the locations to avoid e.g. bathrooms). The
living room is the most likely place for a re to start at night, followed by the kitchen
(where a heat alarm is recommended) and then the dining room. Consideration should
be given to installing smoke alarms in any bedrooms where res might occur, for
instance, where there is an electrical appliance such as an electric blanket or heater,
or where the occupant is a smoker. In addition, consideration should be also given to
installing smoke alarms in any rooms where the occupant is unable to respond very well
to a re starting in that room, such as an elderly or sick person or a very young child.
Checking alarms can be heard
With the alarms sounding in their intended locations check that the alarm can be heard
in each bedroom with the door closed, above the sound of any TV/audio systems. The
TV/audio systems should be set to a reasonably loud conversation level. If you cannot
hear the alarm over the sound of the TV/audio system, the chances are it would not
wake you. Connecting the smoke alarms to one or several Visit receivers will help to
ensure that the alarm is noticed throughout the property.
Positioning
Ceiling mounting
Hot smoke rises and spreads out, so a central ceiling position is the recommended
location. The air is “dead” and does not move in corners, therefore smoke alarms must
11 12
be mounted away from corners. Keep at least 305mm (12") from walls and corners, see
Figure 3. Additionally, mount the unit at least 305mm (12") from any light tting or
decorative object which might prevent smoke entering the smoke alarm.
Wall mounting
If ceiling mounting is impractical, smoke alarms may be mounted on a wall, provided that:
a) The top of the detection element is between 150mm (6") and 305mm (12") below the ceiling;
b) The bottom of the detection element is above the level of any door openings;
Wall mounting should only be considered where close spaced beams or similar obstruc-
tions may preclude ceiling mounting. It is considered to be the responsibility of the
installer/client to determine if the presence of asbestos in the ceiling material would
make ceiling mounting ‘impractical’.
On a sloping ceiling
With a sloping or peaked ceiling, install a smoke alarm within 610mm (24") of the peak
(measured vertically). If this height is less than 610mm (24"), the ceiling is regarded as
being at, see Figure 4.

Installation
Installation procedure
1Select a location complying with the advice in the
Location and positioning section.
2Remove the mounting plate from the smoke alarm
by twisting it in an anti-clockwise direction, see
Figure 5a.
3Place the mounting plate on the ceiling exactly
where you want to mount the smoke alarm. With
a pencil, mark the location of the two screw holes.
4Taking care to avoid any electrical wiring in the
ceiling, drill holes using a 5.0 mm (3/16") drill bit
through the centre of the marked locations. Push
the plastic screw anchors provided into the drilled
holes. Screw the mounting plate to the ceiling.
5Connect the battery to the battery snaps as shown in
the Quick start guide on page 5. Verify that the red
and green LEDs on the cover aluminate as indicated
in the table on the Indication summary on page 4.
6If the smoke alarm is not to be used together
with supplementary Visit receivers, battery
capacity is increased by turning off the radio
Locations to avoid
DON’T place smoke alarms in any of the following areas:
Bathrooms, kitchens, shower rooms, garages or other rooms where the smoke alarm
may be triggered by steam, condensation, normal smoke or fumes. Keep at least 6
meters (20ft) away from sources of normal smoke/fumes.
Locate away from very dusty or dirty areas as dust build-up in the chamber can im-
pair performance. It can also block the insect screen mesh and prevent smoke from
entering the smoke detector chamber.
Do not locate in insect infested areas. Small insects getting into the smoke detector
chamber can cause intermittent alarms.
Places where the normal temperature can exceed 100°F (38°C) or be below 32°F (0°C)
(e.g. attics, furnace rooms, directly above ovens or kettles etc.) as the steam could
cause nuisance alarms.
Near a decorative object, door, light tting, window moulding etc., that may prevent
smoke from entering the smoke alarm.
Surfaces that are normally warmer or colder than the rest of the room (e.g. attic
hatches). Temperature dierences might stop smoke from reaching the unit.
Next to or directly above heaters or air conditioning vents, windows, wall vents etc.
that can change the direction of airow.
In very high or awkward areas (e.g. over stairwells) where it may be dicult to reach
the smoke alarm (for testing, hushing or battery replacement).
Locate the unit at least 1 meter (39") from dimmer controlled lights and wiring as
some dimmers can cause interference.
Locate unit at least 1.5 meters (59") and route wiring at least 1 meter away from
uorescent light ttings as electrical “noise”and/or ickering may aect the unit.

transmission. Do so by pressing the black button on the RF
module for 3 seconds, see Figure 5b. The red LED blinking
for two seconds indicates the link is active, and a stable red
LED light for two seconds indicates that the link is turned o.
7Place the smoke alarm unit on top of the baseplate and twist
it clockwise to attach it. Install all the other alarms similarly.
8Press the test button on each smoke alarm to ensure that
the smoke alarm unit works, see Figure 6.
9If you are using a supplementaryVisit receiver, also make sure
that it lights up a re symbol in red and alerts with sound,
ashes or vibrations (depending on the type of Visit receiver
you are using). For more information, see the Quick start
guide on page 6 and the Visit receiver user manual.
Tamper proong the smoke alarms
The smoke alarm can be made tamperproof to prevent unauthorized removal of the
unit. Proceed as follows:
Break o the small pillar on the base as shown in Figure 7a. To remove the smoke alarm
from the ceiling it is now necessary to use a small screwdriver, to release the catch (push
catch towards the ceiling) and then twist o the smoke alarm, see Figure 7b.
If necessary, it is possible to further secure the smoke alarm by using a No.2 or No.4 (2
to 3mm (1/8") diameter - not supplied) self-tapping screw 6 to 8mm (1/4") long, see
Figure 7d, to rmly lock the smoke alarm and its mounting plate together, see Figure 7c.

Testing, monitoring and maintenance
Your smoke alarm is a life saving device and should be checked periodically. Regularly
check that the red light on the smoke alarm blinks approximately every 45 s to show
the units are powered. Replace the battery if the blinking stops.
Manually testing your smoke alarms
It is recommended that you test your smoke alarms after installation and then at least
weekly to ensure the units are working. It will also help you and your family to become
familiar with the sound of the alarms.
Press and hold the test button until the alarm sounds and the red light blinks (see
Figure 6 on page 15).The alarm will stop sounding shortly after the button is released.
If the smoke alarm has a wireless connection to a supplementary Visit receiver, check
that the green light on the cover of the smoke alarm starts to blink and that the Visit
receiver reacts. See the Quick start guide on page 6 and the Visit receiver user manual.
Release the test button. The smoke alarm and Visit receiver will stop signaling within 40 s.
Repeat this procedure for all other smoke alarms in the system.
WARNING: Do not test with ame.
This can set re to the smoke alarm 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 test button it simulates the eect of smoke in a smoke alarm which it
could experience in a real re. So, there is no need to test smoke alarms with smoke or ame.
17 18
Test/hush button to control nuisance alarms
The smoke alarms have a combined test/hush button to help you control nuisance/
false alarms.
If, when the alarm sounds, there is no sign of smoke or noise to indicate that there is
a re, it should be assumed that it is due to an actual re and the dwelling should be
evacuated immediately.
Check the house carefully in case there is a small re smoldering somewhere.
Check whether there is some source of smoke or fumes, for example cooking fumes
being drawn past the smoke alarm by an extractor.
If there are frequent nuisance/false alarms it may be necessary to re-locate the smoke
alarm away from the source of the fumes.
1 To cancel a false alarm from a smoke alarm (which has its red light blinking rapidly),
press the test/hush button (the smoke alarm will automatically switch to a reduced
sensitivity condition).The smoke alarms will be silenced for a period of approximately
10 minutes. The red and green light on the cover of the smoke alarm will blink every
8 s (instead of 45 s) to indicate that the unit has been silenced.
2 The smoke alarm will reset to normal sensitivity at the end of the silenced period (10
minutes). If additional silenced time is required, simply push the test/hush button again.
3 If kitchen usage/layout is such that there are an unacceptable level of nuisance
alarms, re-locate the smoke alarm further away where it will be less aected by
cooking fumes etc.
We recommend the use of a heat alarm in the kitchen area to avoid such nuisance alarms.

Power supply monitoring
What to do when an alarm is beeping:
If a smoke alarm is beeping about every 45 s with the red light blinking at the same
time, replace the battery.
Battery replacement
A fresh Alkaline battery should last for over a year. When the battery power is low and
replacement is necessary, the smoke alarm will“beep”and the red light will blink at the
same time about once per minute for at least 30 days.The battery must then be replaced.
Also, replace the battery if the alarm does not sound when the test button is pressed.
For maximum reliability, replace the battery at least once a year. When you replace the
battery you must press the test button to check that the smoke alarm is functioning
correctly. Only replace the battery with: Duracell MN1604 alkaline 9V battery.
Warning!
CONSTANT EXPOSURES TO HIGH OR LOW TEMPERATURES OR HIGH HUMIDITY MAY
REDUCE BATTERY LIFE.
Use only batteries specied in marking. Use of a dierent battery may have a detrimental
eect on smoke alarm operation. Prolonged periods of alarm will also reduce battery life.
Cleaning your smoke alarm
Clean your smoke alarm regularly. Use a soft bristle brush or the brush attachment of
your vacuum cleaner to remove dust and cobwebs from the side slots where the smoke
19 20
enters. To clean the cover, wipe with a damp cloth and dry thoroughly.
WARNING: Do not paint your smoke alarm.
Other than the maintenance and cleaning described in this leaet, no other customer
servicing of this product is required. Repairs, when needed, must be performed by the
manufacturer.
Smoke alarm automatic self-test
The smoke chamber in the smoke alarms automatically tests itself every 40 seconds. If
the chamber is degraded it will beep without the red light blinkig at the same time. If
this happens clean the unit. If the beeping persists and the beep does not coincide with
a red light blink, return the unit for service (see Service and support).
Dust and insect contamination
All smoke alarms 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 in the
construction of Bellman & Symfon smoke alarms to minimize the eects of contami-
nation. However it is impossible to completely eliminate the eect of dust and insect
contamination, and therefore, to prolong the life of the smoke alarm 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 alarm should be promptly removed.
In certain circumstances even with regular cleaning, contamination can build up in
the smoke sensing chamber causing the smoke alarm to sound. If this happens the

smoke alarm must be returned for servicing or replacement. 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 and a charge is made for all such
servicing work.
End of life
The entire smoke alarm must be replaced if:
The unit is installed for over 10 years (check the“replace by”date marked on the side
of the unit).
Before the smoke alarm is safely discarded, remove it from the mounting plate, and
disconnect the battery.
Do not put the smoke alarm into a re
The smoke alarm should be disposed in a safe and environmentally sound manner at
your local recycle centre. Contact your local authority for further advice.
21 22
Fire safety advice
When using household protective devices, basic safety precautions should always be
followed, including those listed below.
Please read all instructions.
Rehearse emergency escape plans so everyone at home knows what to do in case
the alarm sounds.
Use the smoke alarm test button to familiarize your family with the alarm sound and
to practice re drills regularly with all family members. Draw up a oor plan that will
show each member at least 2 escape routes from each room in the house. Children
tend to hide when they don’t know what to do. Teach children how to escape, open
windows, and use roll up re ladders and stools without adult help. Make sure they
know what to do if the alarm goes o.
Constant exposures to high or low temperatures or high humidity may reduce battery life.
Nuisance alarms can be quickly silenced by fanning vigorously with a newspaper or
similar to remove the smoke or press the test/hush button.
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
possible eye damage or skin irritation if battery has leaked or corroded.
To maintain sensitivity to smoke, do not paint or cover the smoke alarm in any man-
ner; do not permit any accumulation of cobwebs, dust or grease.
If the smoke alarm has been damaged in any way or does not function properly, do not
attempt a repair. Get your smoke alarm serviced, see the Service and support section.

This appliance is intended ONLY for premises having a residential type environment.
This is not a portable product. It must be mounted following the instructions in this leaet.
Smoke alarms are not a substitute for insurance. The supplier or manufacturer is not
your insurer.
Fire safety hints
Store petrol and other ammable materials in proper containers.
Discard oily or ammable rags.
Always use a metal replace 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
smoldering cigarettes and ashes.
Service central heating systems regularly.
Be sure all electrical appliances and tools have a recognized approval label.
This device cannot protect all persons at all times. It may not protect against the three
most common causes of fatal res:
1Smoking in bed.
2Leaving children at home alone.
3Cleaning with ammable liquids, such as petrol.
Further information can be obtained from the re department.
23 24
Planning your escape route for when the alarms sound
1Check room doors for heat or smoke. Do not open a hot
door. Use an alternate escape route. Close doors behind
you as you leave.
2If smoke is heavy, crawl out, staying close to oor.Take short
breaths, if possible, through a wet cloth or hold your breath.
More people die from smoke inhalation than from ames.
3Get out as fast as you can. Do not stop for packing. Have a
prearranged meeting place outside for all family members.
Check everybody is there.
4Call the re brigade from a neighbor’s house or mobile
phone. Remember to give your name and address.
5NEVER re-enter a burning house.

Alarm limitations
Limitations of smoke alarms
Smoke alarms have signicantly helped to reduce the number of re fatalities in coun-
tries where they are widely installed. However independent authorities have stated that
they may be ineective in some circumstances. There are a number of reasons for this:
Smoke alarms will not work if the batteries are depleted or if they are not connected.
Test regularly and replace the entire smoke alarm when it fails to operate.
Smoke alarms will not detect re if sucient smoke does not reach the smoke alarm.
Smoke may be prevented from reaching the smoke alarm if the re is too far away, for
example, if the re is on another oor, behind a closed door, in a chimney, in a wall
cavity, or if the prevailing air draughts carry the smoke or heat away. Installing smoke
alarms on both sides of closed doors and installing more than one smoke alarm as
recommended in this leaet very signicantly improve the probability of early detection.
The smoke alarms may not be heard.
The radio link to the supplementary Visit receivers may not work due to interference
or due to the signal being blocked by furniture, renovations etc.
A smoke alarm may not wake a person who has taken drugs or alcohol.
The smoke alarms may not detect every type of re to give sucient early warning.
They are particularly ineective with: res caused by smoking in bed, escaping gas,
violent explosions, poor storage of ammable rags and/or liquids, (for example petrol,
paint, spirits etc.), overloaded electrical circuits, arson, children playing with matches.
Smoke alarms don’t last indenitely. We recommend replacement after 10 years as
a precaution.
25 26
RF module features
This smoke alarm is equipped with an RF module that transmits radio signals to one or
several supplementary Visit receivers. A Visit receiver will help to ensure that the alarm
is noticed throughout the property. The alert and signal pattern for the Visit receiver is
found in the product’s user manual.
Activating additional surveillance functions
BE1443 Visit Flash receiver ONLY
By default, all Visit units are factory set to the same radio key, channel 0. This means
that any added Visit receiver within radio range will automatically alert in case of re.
If you pair the smoke alarm to the BE1443 Visit Flash receiver, you get access to addi-
tional network surveillance functions such as low battery, lost connection and hardware
failure warnings. Proceed as follows to pair the units:
1Press and hold the test button on the Flash receiver until the green and yellow LEDs
start to blink. Release the test button.The Flash receiver will now be in programming
mode for about 30 s.
2Press and hold the smoke alarm test button.
3The LEDs on the Flash receiver will blink three times in quick succession to show that
pairing was successful.The Flash receiver will then automatically return to normal mode.
4Test the connection by pressing the smoke alarm test button. The Flash receiver will
start to ash and light up a red LED. It will automatically time out in 40 seconds.
Note: The Flash receiver is also able to distinguish between the activated smoke alarm units.

Changing the radio key
If your Visit receiver is activated for no apparent reason, there might be another Visit
system installed nearby that accidently triggers your system.To avoid the radio interfer-
ence you need to change the radio keys on all units in your system. Proceed as follows:
1Move the desired radio key switches on the smoke alarm unit/s to the up=on
position, see Figure 8.
2Pair all Visit receivers in your system to the smoke alarm unit (see the receiver user
manual for correct pairing procedure).
Please note
All Visit products within the same
system must be set to the same
radio key in order to operate as a
group.
By default, all Visit transmitters are
factory set to the same radio key,
channel 0 and all radio key switches
on the smoke alarms are set to the
O=Down position.
