CHECKS BEFORE USE
650MBX, 670MBX, and 680MBX:
• 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 grille).
• Check the red light flashes every 45 seconds or so.
• When testing linked alarms check that they all
interconnect within 10 seconds.
IMPORTANT NOTES
• Alarms with rechargeable batteries or capacitor
back up may beep for up to 2 hours while the
batteries / capacitors charge.

they know how to use and maintain the alarm.
A: GUIDANCE ON INSTALLATION
P O W E R E D
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
MODELS:
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 necessary to use an RCD for protection,
it should operate independently of any RCD protection for circuits supplying sockets or portable
equipment.
All interconnected alarms should be installed on a single final circuit.
NOTE: The maximum interconnect wiring length is 250 metres. The maximum number of alarms
interconnected together is 12. BRK Dicon smoke alarms should not be connected 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 Diagrams 1 & 2)
1. Use either of the methods of installation
shown in diagrams1 and 2.
When selecting cable for connecting
interlinked smoke alarms the interlink wire
should be treated as live.
The installation method shown in diagram
1 is suitable for a plasterboard or similar
ceiling where access to the void behind it
is available and suitable to mount the
junction box.
The installation method shown in diagram
2 is suitable for concrete or similar
ceilings where access is insufficient or
where surface wiring is necessary.
2. Connect the brown wire to the brown (live)
in the house wiring and the blue wire to the
blue (neutral). NO CONNECTION SHOULD
BE MADE TO THE MAINS ELECTRICITY
SUPPLY EARTH TERMINAL. TERMINATE
HOUSE WIRING EARTH
IN SPARE CONNECTOR.
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.
IMPORTANT: THE PAPER GASKET SUPPLIED
MUST BE FITTED BETWEEN THE REAR OF THE
ALARM AND THE MOUNTING PLATE TO PREVENT
THE ALARM FROM BECOMING CONTAMINATED
BY DUST AND TO ENSURE THE CORRECT
OPERATION OF THE ALARM. Gasket not required
on alarms fitted with protective film on the back.
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.
Fit either locking key into the 'Key Slot' above
the battery drawer handle. Key number 1 locks
the alarm to the base, key number 2 locks the
alarm to the baseplate AND the battery drawer
closed. These keys remain in place and should
only be removed when opening the battery
drawer or removing the alarm from the
baseplate.
LOCKING PINS / KEYS MUST BE FITTED. DO
NOT ATTEMPT TO REMOVE THE ALARM
FROM THE BASEPLATE WITHOUT FIRST
REMOVING THEM.

9. Switch on the mains electricity supply.
BLUE (NEUTRAL)
10. Check that the green light is on and that the red light is flashing every 45 seconds or so.
BLACK or GREY (INTERLINK)
The lights are located behind the grille on the front of the alarm.

11. Press and hold the test button until the alarm sounds. NOTE: On the 670 series, pressing this
button places the alarm in pause mode.
SYSTEMS OF MORE THAN ONE ALARM
JUNCTION BOX
Test each alarm in the system checking that all other alarms in the system are triggered within 10
seconds.
WARNING
BASEPLATE
BROWN Do not attempt to test the alarm with flame heat or smoke, the results may be misleading and may

BLUE damage the alarm.
The dust cover must be removed as late as possible before commissioning. 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 insulation testing
equipment otherwise this will damage the alarm and will invalidate the warranty.

C: WHERE TO LOCATE
1. As a minimum smoke alarms should be located between sleeping areas and potential sources of
fire such as living rooms and kitchens. In single storey homes with one sleeping area a smoke
INSTALLATION USING JUNCTION BOX alarm should be installed in the hallway as close as possible 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.
