The wireless base uses radio signals to interconnect alarms.
When installed, if one unit alarms for an event it will communi-
cate with the other alarms using radio communication. Remote
test and hush functionality can also be added wirelessly using the
KN-RTH-RF accessory
Unit does not support carbon monoxide alarm signals
The wireless base will not recognize a signal from an intercon-
nected CO alarm. However, an interconnected CO alarm will not
hinder the wireless base system. The wireless base will only
receive and transmit smoke and heat alarm signals.
This wireless base is mains powered having a rechargeable
battery system providing back up power for approximately 3
months on mains failure.
Installation Instructions – Introduction
This wireless base is designed for installation by a competent,
qualified electrician, in accordance with the latest I.E.E.
Regulations and complying with relevant building regulations.
• Read these instructions thoroughly before proceeding. People’s
lives depend on it.
• This manual is for use by qualified electricians.
• Wireless alarm base and attached alarms must be powered by a
constant 230V AC, 50Hz supply that is not controlled by any
form of switch. It is not suitable to be connected being con-
trolled / supplied by a light dimmer circuit. Failure to comply
with this directive may lead to product failure / overheating of
components which is outside the terms of the guarantee.
WARNING:
This alarm cannot be operated from power derived from a square
wave or modified sine wave inverter. These types of inverters are
sometimes used to supply power to the structure in off grid
installations, such as solar or wind derived power sources. These
power sources produce high peak voltages that will damage the
alarm.
Kidde recommends to connect alarms and bases to a dedicated
circuit that is separately electrically protected. This helps
minimise interference (EMI) on alarm interconnect line from
CFL's, dimmers, LV transformers etc.
• This wireless base will not detect smoke or heat and must be
installed in conjunction with the specified alarms. Only connect
to the specified models of smoke or heat alarm. Do not connect
to any other brand of alarm/auxilary device unless approved by
Kidde.

Introduction
The RF-SFTP wireless base can be fitted with Kidde Heat and
Smoke Alarm models that have the designation following the
model number.
Up to 15 wireless bases can be fitted in a system due to con-
straints of the supervised system (see installers guide of alarm
for limits of alarms). Although the RF system is limited 15 bases,
the system can have up to 24 devices.
Warning
: Do not interconnect two wireless bases with the hard-
wire as well. This will cause a signal loop that will never exit
alarm once started.
