stallation shown in Fig1 and 2.
When selecting cable for con-
necting interlinked smoke alarms
the interlink wire should be
treated as live.
The installation method shown in
Fig 1 is suitable for a plaster-
board or similar ceiling where ac-
cess to the void behind it is
available and suitable to mount
the junction box.

3. For multiple alarm installations
use a “three core and earth” style
cable between all the alarms to be interconnected and connect the third core
of that cable to the white wire from the smoke alarm. DO NOT use the earth
wire for the interconnect line. This must be treated as live, i.e. insulated and
sheathed. If the alarm is not going to be interconnected, cap the unused
wires.
4. Remove the baseplate from the back of the alarm by twisting anti-clockwise
as far as it will go. (about 12 mm). Detach the locking pin.

• Check battery has been fitted correctly.
• Check alarm is not beeping.
• Test alarm before switching on the electricity supply.
All Alarms:
• Check the green light is on (behind the front grill).
• Check the red light flashes every 45 seconds or so.
• When testing linked alarms check that they all interconnect within 10 second

'" Wiring should be installed by a qualified electrician in accordance with
BS7671. Permanent connection to the fixed wiring of the building should be made in
a suitable junction box. This alarm must not be exposed to dripping or splashing.
Connect the alarm as late as possible in an installation, particularly in new build, to
avoid contamination. Remove the dust cover before applying power.
$ For detailed guidance on the siting of this alarm refer to section C of this
handbook.
"$$ The circuit used to power the alarm must be a 24 hour voltage circuit
that cannot be turned off by a switch. BS5839 Part 6 states that: -
For mains powered alarms, each with an integral standby supply (Grade D), the mains
electricity supply should take the form of either:
a) an independent circuit at the dwelling’s main circuit board, in which case no other
electrical equipment should be connected to this circuit (other than a dedicated
monitoring device installed to indicate failure of the mains electricity supply to the
alarms); or
b) a separately electrically protected, regularly used local lighting circuit.
For mains powered alarms, with no standby supply (Grade E), the mains electricity
supply may only take the form of an independent circuit as per a) above. If it is neces-
sary to use an RCD for protection, it should operate independently of any RCD pro-
tection for circuits supplying sockets or portable equipment.
All interconnected alarms should be installed on a single final circuit.
4. Switch on the mains electricity
supply.
5. Check that the green light is
on and that the red light is
flashing every
45 seconds or so. The lights
are located behind the grille
on the front of the
alarm.
6. Press and hold the test button
until the alarm sounds. NOTE:
On the 670 and
650 series, pressing this but-
ton places the alarm in pause mode.
#)#$#"$
"
Test each alarm in the system
checking that all other alarms in
the system are triggered within
10 seconds.
'"
Do not attempt to test the alarm
with flame heat or smoke, the re-
sults may be misleading and may
damage the alarm.
The dust cover must be removed
as late as possible before com-
missioning. This will reduce the chances of the alarm being contaminated by building
dust etc.
Remove the alarm from the system before testing the wiring with high voltage insula-
tion testing equipment otherwise this will damage the alarm and will invalidate the war-
ranty.
'"$$
1. As a minimum smoke alarms should be located between sleeping areas and poten-
tial sources of fire such as living rooms and kitchens. In single storey homes with
one sleeping area a smoke alarm should be installed in the hallway as close as pos-
sible to the living accommodation. To ensure audibility in the bedrooms it may be
necessary to install more than one smoke alarm, particularly if the hallway is more
than 15m long. In single storey homes with two separate sleeping areas, a minimum
of two smoke alarms is required, one outside each sleeping area. In multilevel or
split level homes as a minimum a smoke alarm should be installed on the ground
floor between the staircase and any rooms in which a fire might start and on each
storey in circulation areas which form part of the escape route (normally hallways
and landings).
$ Heat alarms should not be used in escape routes instead of smoke alarms.
They should only be used in the applications listed below in addition to smoke
alarms and should always be interconnected to smoke alarms.
2. Additional alarms should be installed in bedrooms in anticipation of fires originating
there, caused by faulty wiring, lights, appliances, smokers or other hazards.
3. For best protection, smoke alarms should be installed in every room in your home,
apart from those listed in the ‘LOCATIONS TO AVOID’ section. Heat alarms should
be used in kitchens, boiler rooms, laundry rooms, garages and such like where
smoke alarms would be unsuitable. All alarms must be interconnected.
4. Install smoke alarms in circulation areas at a distance no greater than 7.5m from the
farthest wall, no greater than 7.5m from a door to any room in which a fire might
start and no greater than 7.5m from the next smoke alarm.
5. When heat alarms are installed in a room, they should be at a distance no greater
than 5.3m from the farthest wall no greater that 5.3m from a door to any room in
which a fire might start and no greater than 5.3m from the next heat or smoke alarm.
6. As it is impossible to predict the source of a fire the best location for an alarm is the
centre of the room or hallway. If it is necessary to locate the smoke alarm on a wall
always locate the detection element of the alarm 150mm to 300mm (6 to 12 inches)
below the ceiling and the bottom of the alarm above the level of doors and other
openings.
$.*<*5*:6;;18=5-78<+.?*5568=7<.-.
7. In rooms with simple sloped, peaked or gabled ceilings install smoke alarms 900mm
(3 feet) from the highest point of the ceiling. ‘Dead air’ at the peak of the ceiling may
prevent smoke from reaching the alarm in time to provide an early warning.
8. Closed doors and other obstructions will interfere with the path of smoke and heat

Abnormal air conditions may cause the highly sensitive alarm to give a ‘false’ alarm. DO
NOT DISCONNECT THE ALARM. If no fire is apparent, ventilate the room and/or oper-
ate the alarm pause (If fitted).
'" IF THERE IS ANY QUESTION AS TO THE CAUSE OF AN ALARM, ALWAYS
ASSUME THAT IT IS DUE TO AN ACTUAL FIRE AND FOLLOW YOU FIRE EMER-
GENCY PLANS. Do not assume the alarm is a nuisance alarm and activate alarm pause
(if fitted).
Dust can have an adverse effect. Vacuum as recommended above.
Do not paint the unit.
Other factors such as nicotine contamination may also adversely affect the alarm.
"*-28*,<2>.87<.7<;
Ionisation type smoke alarms utilise a tiny amount of radioactive material, 0.9 microcuries
(30 kilobequerels) of Americium 241, to detect smoke. This material is in the form of a
sealed source and represents no hazard whatsoever to anyone installing or using the
smoke alarm. Any stray particles would be unable to “penetrate the dead layer of skin
and thus do not constitute an external hazard”. (Radiation Protection Guidance for Scien-
tists and Physicians). All BRK® ionisation smoke alarms have been rigorously tested by
the National Radiological Protection Board to ensure absolute safety.

"$$ These smoke and heat alarms are intended primarily for use in sin-
gle-family occupancy private dwellings. For use in other applications the manufac-
turers advice should be sought. $#$&
$ locate alarms: -
1. In turbulent air from fans, heaters, doors, windows, etc.
2. In high humidity areas such as bathrooms and shower rooms or where the temper-
ature exceeds 39ºC (100ºF) or falls below 5ºC (40ºF)
3. At the peak of an ‘A’ frame ceiling – dead air at the top may prevent smoke and
heat from reaching the alarm to provide an early warning.
4. Less than 300mm (12 inches) from a wall when mounted on the ceiling.
5. In insect infested areas. Tiny insects may affect performance.
6. (Smoke alarms) in poorly ventilated kitchen or garage. Combustion particles from
cooking or car exhaust could trigger a nuisance alarm
7. In very dusty or dirty areas – dirt and excessive dust can impair the performance
of the alarm.
8. Within 300mm (12 inches) of a light fitting or room corners.
9. In locations that would make routine testing or maintenance hazardous. (e.g. over
a stairwell).
10. On poorly insulated walls or ceilings.
11. Near objects such as ceiling decorations that might impede the path of smoke or
heat to the alarm.
12. Within 1500mm (5 feet) of a fluorescent light fitting and keep wiring at least
1000mm (39 inches) from these fittings. Do not install alarms on circuits containing
fluorescent light fittings or dimmer switches.

.*<=:.;
• Operating Lights – A continuous green light indicates the alarm is receiving mains
power. The red light doubles as an alarm source indicator and flashes approxi-
mately every 45 seconds to confirm circuitry integrity.
• Alarm Source Indicator – Red light will flash every second in the unit originating the
alarm. Red lights on other alarms flash every 45 seconds.
• Alarm Pause (670 & 650 range only) – Silence your smoke alarm by momentarily
pressing the test button. Ideal when non-emergency smoke (e.g. cooking fumes)
cause nuisance alarms. Red light flashes every ten seconds to remind you that the
alarm has been silenced. Double beep indicates that the alarm has automatically
reset after approximately 10 minutes.

Smoke and heat alarms properly installed and maintained are an essential part of a
good home fire safety programme. Review fire hazards and eliminate dangerous con-
ditions wherever possible. When fire strikes a prepared and practiced escape plan
could prove vital. Your local fire brigade may be willing to advise you. Call them and
ask. Consider and discuss the following safety hints:
• Ensure everyone is familiarized with the alarm signal.
• Always test doors with your hands before flinging them open. If they feel warm, fire
may be walled up behind them – leave closed and find another escape route.
• Don’t waste time collecting possessions. Rouse all occupants and leave the build-
ing; your life is more valuable.
• $%$#$)%$$$""%$
• Keep everyone in a set meeting place after your escape.
• If trapped inside, stay close to the floor, cover your mouth with cloth and conserve
breath while you crawl to safety.
• Keep all windows and doors closed except for escape purposes.
• Prepare and practice an escape plan before a fire starts.
Draw a floor plan. Have fire drills often. Practise your escape.
# $
Vacuum every six months to keep unit working efficiently by firstly turning off the
mains electricity supply and vacuuming through the vents using a soft brush attach-
ment. Keep the nozzle from touching the unit. SWITCH POWER BACK ON WHEN
YOU HAVE FINISHED.
Test the alarm once a week by: -
• Checking that the green light is on and that the red light is flashing every 45 seconds
or so. The lights are located behind the grille on the front of the alarm.
• Press and hold the test button until the alarm sounds. NOTE: Pressing this button on
alarms in the 670 and 650 series also places the alarm in pause mode.

Rechargeable Lithium batteries provide approximately 6 months back up power sup-
ply in the event of a mains supply failure. The alarm may beep every 45 seconds for a
few hours after a mains supply failure while the batteries re-charge.
High performance rechargeable capacitors provide a back up power supply in the
event of a mains supply failure. The alarm may beep every 45 seconds for a few hours
after installation or during/after a mains supply failure. In both of these events the
rechargeable capacitors will need to charge/re-charge when mains supply is restored.
$:8=+5.;188<270
Problems are indicated by four events: -
1. Alarm does not sound upon pressing the test button
2. Green light does not illuminate when mains power is on.
3. Red operating light remains steadily on, or off (i.e. does not flash every 45 seconds
when alarm is in standby).
4. Alarm emits a beep every 45 seconds when back up power supply should be fully
charged.
Try the following: -
1. Inspect the fuse in the power circuit to the alarm
2. Gently vacuum as detailed in ‘Simple Maintenance’.
3. For MBX models only, replace the battery.
4. Call a qualified electrician to inspect the house wiring and connections to the alarm.
If these procedures do not eliminate the problem. DO NOT ATTEMPT REPAIRS. In the
first instance contact the manufacturer for further advice.
