2. INTRODUCTION
The Ei168 RadioLINK Base transmits a Radio Frequency (RF) alarm signal when
the unit attached to it senses fire. When it receives an RF alarm signal from anoth-
er Ei168 Base, the attached smoke or heat alarm will sound. It therefore eliminates
the need to run long interconnect wires between all the smoke alarms on different
floors and in different rooms.
It is designed for use with the Easi Fit range of Mains Powered Smoke/Heat
Alarms. The RadioLINK Base itself, is also mains powered and has rechargeable
lithium cells for back-up in the event of mains failure. The RadioLINK Base will
normally be wired to the nearest mains circuit in the ceiling (usually the lighting
circuit, provided unswitched live is available). The Smoke/Heat Alarm is then slid
on to the RadioLINK Base rather than to its normal mounting plate. As many as
12 units can be interconnected in this way.
It is essential
to house code the RadioLINK Bases to ensure they will not
accidently signal to nearby systems. This is easily done as explained in
section 3 below.
(The units will all communicate with each other (provided they are within range) as installed
i.e. without any house coding).
With an Ei410 Remote Control (optional) the system is much more versatile and
user-friendly. It allows you to remotely test, silence nuisance alarm (Ei161R &
Ei166R only) and even quickly locate which unit is sensing fire.
