$ 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.

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

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.

• 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.

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
