Application
•
This surface mount pattress is for use with
KIDDE Fyrnetics, Hard Wired Smoke, Heat and
CO Alarms, where surface cabling is being
used, such as in retrofit applications.
Usage
•
This is designed for installation by a qualified
electrician, in accordance with the current IEE
regulations. Failure to install correctly can result
in a fatal shock or fire hazard.

pattress provide flexibility of cable entry, for
ease of use. A small rib on the edge of the
pattress lines up with a mark on the alarms
base plate, to ensure correct alignment.

manufacturer literature/manual shipped with
alarm. Also refer to Building Regulation
requirements if applicable, plus BS5839 Pt 6.
