Installation and User Instructions for S841 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 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

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.

(ISO 15693) smart cards, and the card serial number on
Philips MIFARE smart cards.
For either type of card, the S841 supports the use of
unencoded cards (where only the unique card serial number is
read). In the case of Texas Instruments (TI) cards, an encoded
card number can be read. Encoding formats supported include
TI's own formats and the "smartMAX" format.
