All Alarms:
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 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. 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. IMPORTANT INFORMATION: THE COLOUR CODING FOR ELECTRICAL CABLES USED IN
BUILDING WIRING HAS BEEN CHANGED AS FOLLOWS:-
Old colour New (harmonised) colour
Red Brown
Yellow Black
Blue Grey
Black Blue
The new (harmonised) colour cables may be used on site from 31 March 2004. New installations
or alterations to existing installations may use either new or old colours, but not both, from 31st
March 2004 until 31st March 2006. Only the new colours may be used after 31 March 2006. For
more information see Amendment No: 2 to BS 7671:2001 and guidance publications.
See also www.iee.org/cablecolours
When selecting cable for connecting interlinked
smoke alarms the interlink wire should be
treated as live.
2. Use either of the methods of installation
shown in diagrams1 and 2.
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.
3. 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.
4. 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.
5. 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.
