Anyone know anything about fire/smoke alarm installations? A relative
is getting nagged by the local Fire Dept who want grade F LD2 smoke
detectors installed in an old B&B and have supplied a copy of the
Department for Local Communities booklet “Do You Have Paying Guests?”
http://www.communities.gov.uk/public...e/payingguests
This document implies, page 14, that grade F smoke detectors are
“wirelessly connected” at least and a heat detector in the kitchen is
linked in too.

However, another document “FIRE ALARMS IN DWELLINGS” by John Ware at
http://www.electrical.theiet.org/wir...s.cfm?type=pdf
gives an ambiguous picture that for grade F the detectors may not need
to be linked.
The relevant standard is BS 5839: Part 6: 2004, though as that costs
£200 I am not about to buy it.

So do grade F smoke detectors, the minimum requirement, have to be
interlinked (wireless or cable) or not ?

thanks
