Product Description
The Ei168 RadioLINK Base transmits a radio frequency
(RF) alarm signal when the unit attached to it senses fire.
When it receives an RF signal from another Ei168 Base,
the attached alarm will sound. It therefore eliminates the
need to install long interconnect wires between all the
alarms on different floors in different rooms.
The Ei168 RadioLINK Base is designed for use with the
Easi Fit range of mains powered alarms. The Ei168 itself
is also mains powered and has rechargeable lithium cells
for back-up in the event of mains failure.
The Ei168 base will normally be wired to the nearest
mains circuit in the ceiling (usually the lighting circuit).
The alarm is then slid onto the base rather than to its
mounting plate. As many as twelve units can be
interconnected in this way
The RF range can be extensively improved by either
adjusting the wire antenna or by converting the base into
a “repeater” i.e. re-transmission of the RF signals.
The Ei168 has built in circuitry to aid suppression of
voltage transients and RF interference.
Operation
• In normal standby mode the amber indicator will light
to indicate transmission of an RF signal
• In code mode, the amber indicator will flash to
indicate the number of other RF alarms that have
been “learned” in the system
• The red indicator on the alarm attached to the Ei168
Base will flash rapidly to show an alarm condition for
the smoke detector
• The amber light will flash every 10 seconds to
indicate that the battery back up is depleted

Installation & Placement
Place the Ei168 Base on the ceiling/wall and mark the screw holes. Drill with a
suitable drill bit, insert the screw plugs, connect to the nearest mains circuit
and screw the base into position.
The RF Bases should be house coded to prevent possible interference from
neighbouring installations – see instructions for more details.
Alarms should be placed in accordance with the general guidelines shown in
the diagram above. These recommendations are based on the problem of
areas of “dead air” close to corners of rooms and apexes of ceilings, which
could result in the prevention of smoke reaching the smoke detector
House Code Procedure
1. Connect the base to the
mains circuit and slide on
associated alarm.
2. Hold the house code switch
(with a small screwdriver)
until the yellow light turns on
and then release
3. Similarly, place other bases
into house code mode
4. Check that the number of
yellow flashes (on each base)
corresponds to the number of
bases in your system
5. Remove all bases from house
code
6. Button test each alarm
(attached to each base) to
check your system
