A: GUIDANCE ON INSTALLATION
WARNING: 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.
NOTE: For detailed guidance on the siting of this alarm refer to section C of this
handbook.
IMPORTANT: 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.
P O W E R E D
NOTE: The maximum interconnect wiring length is 250 metres. The maximum num-
ber of alarms interconnected together is 12. BRK smoke alarms should not be con-
nected to any model produced by another manufacturer.
The location of the alarms must comply with the applicable building codes and the
advice in section C: WHERE TO LOCATE below.
B: INSTALLATION
(See fig 1,2, and 3)
For surface mounting 670, 650 and 680 series alarms.
1. Use either of the methods of in-
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.
2. Connect the brown wire to the
brown (live) in the house wiring
and the blue wire to the blue (neu-
tral). NO CONNECTION SHOULD
BE MADE TO THE MAINS ELEC-
TRICITY SUPPLY EARTH TERMI-

NAL. TERMINATE HOUSE
WIRING EARTH IN SPARE CON-
NECTOR.
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.
650MBX, 670MBX and 680MBX Detach battery door screw from the base
plate. Open the battery door on the back of the alarm, connect the battery,
close the door and secure with the screw provided before fitting the alarm to
the baseplate. Test the alarm using the test button.
5. Attach the flat side of the mounting plate and tighten screws to fit snugly
against the pattress or junction box and ceiling or wall.
6. Bring the power connector through the centre opening of the plate.
7. Plug the lead into the rear of the alarm.
8. Place the alarm on the baseplate by lining up arrows on the baseplate and the
alarm rim and twist clockwise to fasten.
To secure the alarm to the baseplate, insert the locking pin (removed from the
base in 5 above) into the 'T' shaped slot located above the arrow on the rim of
the alarm.
LOCKING PINS / KEYS UST BE FITTED. DO NOT ATTEMPT TO REMOVE THE
ALARM FROM THE BASEPLATE WITHOUT FIRST REMOVING THEM.
For 600 Series alarms supplied in the 770,750 and 780 series with
DS700docking base.
1. Connect the brown (live) in the house wiring to connector Land the house blue
wire (Neutral) to connector N.

CONNECTOR MARKED E. See Fig 2
2. 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 connector marked I. DO NOT use the earth wire for the interconnect
line. This must be treated as live, i.e. insulated and sheathed.
3. Locate the molded arrow on the side of the base and smoke alarm see fig 3.
Position the smoke alarm just below the base with both arrows in the same
orientation and locate the alarm onto the base by gently applying pressure
until the alarm 'clicks' into place.
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:

C: WHERE TO LOCATE
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).
NOTE: 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.
NOTE: Heat alarms should not be wall mounted.
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
