Interconnecting Alarms
Note:
A maximum of twelve EIB141RC / EIB144RC /
EIB146RC Smoke or Heat Alarms may be interconnected.
Up to 8 additional accessories may also be connected.
If you wish to connect more than 12 Alarms contact your
local distributor.
Systems using more than 3 or 4 Alarms must be very
carefully planned to ensure nuisance/false alarms are
not excessive. e.g. from cooking fumes or steam. The
following is suggested:
• An Alarm Control Switch (model EIB1529RC) or a
Fire/CO Alarm Controller (model EIB450) should be
incorporated into the system and be readily accessible
to all occupants so that the source of an alarm can be
quickly identified.
• All Alarms must be cleaned and maintained regularly.
• A qualified person must be on call to quickly remove
any nuisance units (i.e. units with red light flashing
rapidly) which are causing all the other Alarms to
sound.
WARNING:
Do not connect these Alarms to any
other model produced by another manufacturer.
Doing so may damage the Alarms and could result in
a shock or fire hazard.
Wiring must be installed in compliance with AS3000.

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.
