About the BE1551 Visit smoke alarm
Intended purpose
This device is part of the Visit alerting system. The intended purpose of the system is to
alert deaf and hard of hearing people of important signals in their home. The smoke alarm
transmitter detects smoke and smoldering re at an early stage and sends a signal to the
Visit receiver that alerts the user with sound, ashes or vibrations.
Intended user group
The intended user group consists of people of all ages with mild to severe hearing loss or
deafness that need audio, visual or sensory amplication of smoke alarms.
Intended user
The intended user is a person with mild to severe hearing loss or deafness.
Principle of operation
The Visit alerting system consists of a set of wirelessly connected transmitters and receiv-
ers that are located across the home. When a transmitter detects an activity, it signals
the Visit receiver that alerts the user with sound, ashes or vibrations. In order to use the
system, you need at least one transmitter and one receiver.
A smoke alarm is an early warning device. Used correctly it can give you and your
family valuable extra time to escape. When the alarm sounds, immediately evacuate
the premises before beginning any investigation.
This device will not restore normal hearing and will not prevent or improve a hearing
impairment or deafness resulting from organic conditions.
This smoke alarm is equipped with a radio 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 explained in the product’s user manual.

battery every min every min every 5 s
When the smoke alarm warns for low battery, you have at least 30 days to replace
it. Bed shakers connected to the BE1580 Alarm clock or the BE1441/BE1442 Flash
receiver will not vibrate when the smoke alarm battery level is low.
Test interval
Test the smoke alarm and radio connection regularly, preferably each week, e.g. during
cleaning, but at least once per month, see Testing and maintenance. Always test it
immediately after any holidays or other extended periods of absence. Clean it with a
damp cloth. After changing battery, vacuum clean with a soft brush. Do not paint over
the smoke alarm.
Using broadcast
If you want the smoke alarm signal to be transmitted to all Visit receivers within radio
range, you can activate broadcast mode. This will override the radio key settings.
Here is how you activate broadcast mode:
1Open the smoke alarm front cover to access the radio button, see Overview.
2Press the radio button three times in quick succession. The radio LED blinks three
times to show that broadcast mode is activated.
Battery warnings will only be transmitted to units with the same radio key.
To disable broadcast, you need to select a new radio key, see Changing the radio key.

EN
The smoke alarm will stop sounding shortly
after the button is released and the Visit
receiver will time out within 40 s.

Changing the radio key
If your Visit system is activated for no reason, there is probably a nearby system that triggers
yours. In order to avoid radio interference, you need to change the radio key on all units.
Systems with dierent types of transmitters
Change the radio key on all other transmitters in the system by moving any of the radio
key switches, see the corresponding transmitter user manual.

Location and positioning
Sucient smoke must enter your smoke alarm before it will respond. Your smoke alarm
needs to be within 7.5 meters (25 ft.) 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).
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 7.5 meters (25 ft.)
from the door to any room where a re may start and block your escape from the house.
Single storey dwelling
If your home is on one level, 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 you can hear it loudly enough to wake you in the bedroom, see Figure 1.
Preferably the smoke alarms should be connected to a Visit receiver so as to give an
additional warning throughout the property.
If your home is very large and the corridor or hallway is more than say 15 metres (50
ft.) long, one smoke alarm will not be sucient. This is because no matter where it is
located it will be more than 7.5 metres (25 ft.) from potential res.
Minimum protection level
On each storey
In each sleeping area
Every 7.5 metres of hallways & rooms
Within 3 metres of all bedroom doors
In houses with more than one sleeping area, smoke alarms should be placed between
each sleeping area and the living area, see Figure 2.
Multi Storey Dwellings
If your home has more than one oor, at least one smoke alarm should be tted on each
level, see Figure 3.
Connecting the smoke alarms to one or several Visit receivers will help to ensure that
the alarm is noticed throughout the property.
Recommended protection level
in addition
In every room, except
bathrooms and kitchens
13
Recommended Protection
Fire authorities recommend you put individual smoke alarms in or near all the rooms
where re is most likely to break out (apart from the locations to avoid, mentioned below).
The living room is the most likely place for a re to start at night, followed by the kitchen
and then the dining room. You should also consider putting smoke alarms in any bed-
rooms 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. You could also consider
putting smoke alarms in any rooms where the occupant is unable to respond very well to
a re starting in the 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
On a ceiling
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 be
mounted away from corners. Place the unit at least 0.3 m from any light tting or deco-
rative object which might obstruct smoke entering the smoke alarm. Keep at least 0.3 m
away from walls and corners, see Figure 4.
On a wall
When a ceiling position is not practical (for example on a ceiling having exposed beams or
joists, or built-in radiant heating) put the top edge of your smoke alarm between 15 and
30 cm below the ceiling. Keep at least 0.3 m from corners, see Figure 4 and 5.
On a sloping ceiling
In areas with sloping or peaked ceilings install your smoke alarm 0.90 m from the highest
point measured horizontally, because “dead air”at the apex may prevent smoke from
reaching the unit, see Figure 5.

Locations to avoid
Don’t place your smoke alarm in any of the following areas:
Bathrooms, kitchen, shower rooms, garages or other rooms where the smoke alarm
may be triggered by steam, condensation, normal smoke or fumes.

Testing and maintenance
Your smoke alarm is a life saving device and should be checked periodically. Regularly
check that the status LED on the smoke alarms ashes once a minute to show the units
are powered. Replace the battery if the blinking stops.
Manually testing your smoke alarm
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, see Installation. The alarm will
stop sounding shortly after the button is released.
If you are using a supplementary Visit receiver, check that the red Visit LED on the
receiver lights up and that it starts to sound, ash or vibrate depending on the receiver.
See Installation on page 3 and the corresponding Visit receiver user manual.
The receiver will time out within 40 seconds.
Repeat this procedure for all other smoke alarms in the system.

EN
Attics (uninsulated) or other places
where extremes of temperature may
occur (below 4°C or above 40°C).
Near a decorative object, door, light
tting, window molding etc., that
may prevent smoke from entering
the Smoke Alarm.
Surfaces that are normally warmer
or colder than the rest of the room
(forexample attic hatches, uninsu-
lated exterior walls etc). 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 where
it may be dicult to reach the alarm
for testing or battery replacement.
Locate unit at least 1.5 m away from
uorescent light ttings as electrical
“noise” and/or ickering may aect
the unit.
Locate away from very dusty or
dirty areas as dust build-up in the
chamber can make unit too sensitive
and prone to alarm. It can also block
the insect screen mesh and prevent
smoke from entering the chamber.
Do not locate in insect infested areas.
Small insects getting in to the cham-
ber can cause intermittent alarms.

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.
Nuisance alarms
If, when the alarm goes o, there is no sign of smoke, heat or noise to indicate that there is
a re, you should rst get your family into a safe place, before you start investigating.
Check the house carefully in case there is a small re smouldering 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 so, simply fan the smoke away
with a newspaper or similar.
If the cause of the alarm is not clear, it should be assumed that it is due to an actual
re and the dwelling should be evacuated immediately.
If there are frequent nuisance/false alarms it may be necessary to re-locate the smoke
alarm away from the source of the fumes. We recommend the use of a heat alarm in
the kitchen area to avoid such nuisance alarms.
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 sides and cover slots where the
smoke enters. Keep cover closed while cleaning.
Do not vacuum or brush inside the smoke alarm. Do not paint your smoke alarm.
Other than the maintenance and cleaning described in this leaet, no other custom-
er servicing of this product is required. Repairs, when needed, must be performed by
the manufacturer.
Dust & insect contamination
All smoke alarms are prone to dust and insect ingress which can cause false alarms.
Thelatest design, materials and manufacturing techniques have been used in the con-
struction of our alarms to minimise the eects of contamination. 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 re-
moved. In certain circumstances even with regular cleaning, contamination can build
17
up in the smoke sensing chamber causing the alarm to sound. If this happens the
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 guarantee
and a charge is made for all such servicing work.
Replacing the Battery
A fresh Alkaline battery should last for over three years. When the battery power is low
and replacement is necessary, the alarm will“beep”and the red light will ash 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, check the battery at least once a year. When you replace the
battery you must press the test button to check that the alarm is functioning properly.
Only use the brand and type of battery specied in the instructions. Using another
battery could result in re or personal injury.
Do not put the battery into a re
The battery should be disposed of in a safe and environmentally sound manner at
your local recycle centre. Contact your local authority for further advice.
End of life
The entire smoke alarm must be replaced if the unit was installed more than 10 years ago
(check the“replace by” date marked on the side of the unit).
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.
Fire safety advice
When using household protective devices, basic safety precautions should always be
followed, including those listed below.
18
EN
Please read all instructions.
Constant exposures to high or low
temperatures or high humidity may
reduce battery life.
To maintain sensitivity to smoke, do
not paint or cover the smoke alarm in
any manner; do not permit any accu-
mulation of cobwebs, dust or grease.
Do not tamper with the chamber.
Youmay safely change the battery
and clean the smoke alarm following
the instructions in this leaet.

Planning your escape route
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 pack-
ing. Have a prearranged meeting place outside
for all family members. Check everybody is there.
4Call the Fire and Rescue Services from a neigh-
bour’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 countries
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.

Fire safety hints
Discard oily or ammable rags.
Store petrol and other ammable
materials in proper containers.
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.
Never smoke in bed. In rooms where
you do smoke, always check under
cushions for smoldering cigarettes
and ashes.
Keep matches away from children.
Service central heating systems regu-
larly.
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:
Smoking in bed.
Leaving children at home alone.
Cleaning with ammable liquids,
such as petrol.
Further information can be obtained
from the Fire and Rescue Services.
Rehearse emergency escape plans so
everyone at home knows what to do
in case the alarm sounds.
Nuisance alarms can be quickly
silenced by fanning vigorously with
a newspaper or similar to remove the
smoke or press the test 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.
If the smoke alarm has been dam-
aged in any way or does not function
properly, do not attempt a repair. Get
your smoke alarm serviced, see the
Service and support section.
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. Chil-
dren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.
This appliance is intended ONLY for
premises having a residential type
environment.
This is not a portable product. It must
be mounted following the instruc-
tions in this leaet.
Smoke alarms are not a substitute for
insurance. The supplier or manufac-
turer is not your insurer.

Smoke alarms will not detect re if
sucient smoke does not reach the
smoke alarm. Smoke may be prevent-
ed 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. Install-
ing 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 ev-
ery type of re to give sucient early
warning. They are particularly ineec-
tive 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.

If the device appears to be damaged or doesn’t function properly, follow the instructions
in the user guide and this leaet. If the product still doesn’t function as intended, contact
your local hearing care professional for information on service and warranty.
Operating conditions
Operate the device in a dry environment within the temperature and humidity limits
stated in this leaet. If the device gets wet or is exposed to moisture, it should no longer
be regarded as reliable and should therefore be replaced.
Cleaning

cleaners, aerosol sprays, solvents, alcohol, ammonia or abrasives. This device does not
require sterilization.
Warranty conditions
Bellman & Symfon guarantees this product (excluding the battery) for two (2) years from
date of purchase against any defects that are due to faulty materials or workmanship.
This guarantee only applies to normal conditions of use and service, and does not
include damage resulting from accident, neglect, misuse, unauthorized dismantling, or
contamination howsoever caused. This guarantee excludes incidental and consequen-
tial damage. Furthermore, the warranty does not cover Acts of God, such as re, ood,
hurricanes and tornadoes.
This warranty gives you specic legal rights and you may also have other rights that vary
with territory. Some countries or jurisdictions do not allow the limitation or exclusion of
incidental or consequential damages, or limitations on how long an implied warranty
lasts, so the above limitation may not apply to you.
This guarantee is in addition to your statutory rights as a consumer. The above warranty
may not be altered except in writing signed by both parties hereto.
