4.2 Interconnecting Alarms

Note: A maximum of twelve Ei141/144/146/161RC
/164RC/166RC Smoke or Heat Alarms may be
interconnected along with an Ei128R pattress with relay
(see "ACCESSORIES" section on page 16).
If you wish to connect more than twelve alarms contact
your local distributor (see page 16 for details).
Systems using more than 3 or 4 alarms must be very
carefully planned to ensure nuisance alarms are not
excessive. e.g. from cooking fumes or steam. The
following is suggested:
• A Smoke Alarm Locator Switch (model Ei159 for use
with Ei141/144/146) or a Smoke Alarm Control Switch
(model Ei1529RC for use with Ei161RC/164RC/
166RC) 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 type of Ei Alarm (apart from those listed
above) or 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 local
regulations.
In the UK it is recommended that the following
coloured cores are used (for example with triple flat
6243Y cable).
