User's Manual

Installation and User Instructions for S843 Readers
You should find that the
backplate has holes for
connection to most
standard electrical
backboxes.
With the backplate off (see above), mount
the backplate adjacent to the opening edge
of the door and at a convenient height.
Feed the required cables through the
backplate:
The cable from the controller.
The cable from the heater, if used (must
be a separate cable).
A cable from a Remote Interface Module
(RIM), if used. A RIM can reduce cable
lengths to door furniture.

The optional heater kit maintains the reader at
the correct temperature when mounted
outside. With the backplate off, remove the
backing paper from the two elements, then
stick them to the inner sides of the reader. The
heaters must be connected to a 24V AC supply
(min 25VA).
When mounting outside, the two-part gasket kit
must be fitted:
a) Remove the backplate from the reader
by releasing the two securing
screws.
b) Remove the cutouts and backing paper
from the two gaskets, then stick them to
the backplate as shown.
