affected, Part J applies whenever a heat-

Carbon Monoxide alarms should be installed

INFORMATION FOR PRO INSTALLERS
Information in this section is intended for
registered electrical contractors. It assumes
that the reader is familiar with the Wiring Rules
and is an Authorised Person, as defined in the
Wiring Rules.
Chapter 56 of the Wiring Rules does not apply to
domestic and similar premises (see rule 560.2).
Accordingly, it is not necessary, among other
things, that fire-resistant supply cables be used
when installing Nest Protect units.
In existing installations, power supply to each
interconnected mains-powered smoke alarm
may be derived from a local, frequently used
lighting circuit. Accordingly, multiple circuits
may supply power to the smoke alarms in a
single installation. Ensure that the power supply
is disconnected at each such smoke alarm
before starting work.
