Installation and User Instructions for S854 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.

The S854 is able to read Personal Identity Verification (PIV II) type A 
and B, Philips MIFARE and Philips MIFARE DESfire smart cards. 
For Philips MIFARE and Philips MIFARE DESfire cards, the S854 
supports  the use of unencoded cards (where only the unique card 
serial number is read), or cards encoded with a card number. 
Several encoding formats are supported. 
 
The reader can simultaneously support two different card 
types/formats (e.g. non-encoded MIFARE and smartMAX-encoded 
MIFARE DESfire, or non-encoded MIFARE and smartMAX-encoded 
MIFARE). The reader is automatically configured to accept the first 
two card types/formats presented after power is applied.
