In the UK it is recommended that the following
coloured cores are used (for example with triple flat
6243Y cable).
230V supply Brown
Neutral Grey - sleeved blue at terminations
Interconnect Black
The interconnect wire (minimum 0.75mm
2
cable) must
be treated as if it was Live. It should be insulated and
sheathed.
A maximum of 250 metres of wire can be used (maximum
resistance between detectors 50 Ohms).
These Smoke/Heat Alarms should be interconnected
only within the confines of a single family living unit. If
they are connected between different units there may
be excessive nuisance/false alarms. Everybody may
not be aware that they are being tested or that it is a
nuisance/false alarm caused by cooking etc.
Ensure the alarms operate correctly - see “TESTING &
MAINTAINING YOUR ALARM” section of the USER
INSTRUCTIONS.
Note: For RadioLINK (wireless) interconnect and
remote control each alarm must be fitted with an
Ei168RC Alarm Base.
Smoke Alarm - Optical or Ionisation?
Both types respond in all standard fires but each type
may respond faster to particular fires as shown.
Fire Authorities states:
“If your home has more than one floor, at least one
alarm should be fitted on each level”.
