ENVIRONMENTAL PROTECTION
Waste electrical products should not be disposed of with household waste. Please recycle
where facilities exist. Check with your Local Authority or retailer for recycling advice.

Application

• This surface mount relay pattress is for use with
Kidde Fyrnetics & Firex, Hard Wired Smoke &
Heat alams, where surface cabling is being used,
such as in retrofit applications. It can be used, via
a suitable relay control, to trigger auxiliary
devices such as door closers, warning lights,
horns, Warden call systems etc.

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.
• Alarms must be connected direct to the Consumer
Unit on a separate circuit – see current Wiring
Regulations.
• Knock-outs on the underside and edge of the
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.
• Site and select alarm type in accordance with
manufacturer literature/manual shipped with
alarm. Also refer to Building Regulation
requirements if applicable, plus BS5839 Pt 6.
• Isolate mains power before commencing work.
• Never remove/refit the cable harness whilst mains
power is present.
• Crossing line and neutral connections or line and
interconnect connections will fatally damage all
interconnected alarms invalidating the guarantee.
• Never Meggar Test an installation, without
disconnecting any connected alarms (this can
permanently damage the alarm and invalidates
the guarantee).

Important Notes

• Up to 23 Mains powered Kidde Fyrnetics &
Firex Smoke or Heat interconnectable alarms
may be wired into this relay unit.
• Any devices hung off this relay must not give
an alarm state until relay contacts have been
activated for at least 200 milli-seconds.
• All alarms with secondary power back-up
continue to function, even if there is loss of
mains power, but this relay will not be able to
function – it requires a healthy 230V supply.
• By default, this relay will not reset until alarm
ceases to sense smoke/heat that has caused the
alarm to trigger.
• As in illustration 1, bring mains cabling into
pattress terminal block via knock-out selected
and fix pattress to ceiling with 2 screws.
(If using dry lining box, select appropriate holes
on pattress and secure with machine screws.)
• Connect flying leads on alarm cable harness to
appropriate terminals and ensure polarity is
correct.
• Install and test alarm by following guidance in
Installer Manual of alarm.
