G4S Technology S823 User Manual

Installation and User Instructions for S823 Readers

The S823 is a
20mA current loop seudo-random communications
The S823 is able to read Philips MIFARE and Philips
MIFARE DESfire smart cards.

For either type of card, the S823 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 smartMAX­encoded MIFARE DESfire, or non-encoded MIFARE and
smartMAX-encoded MIFARE). The reader is
automatically configured to accept the first two card
types/formats presented.

If the reader needs to read both MIFARE and MIFARE DESfire cards, make sure that one of each card
is presented to the reader immediately after the reader has been installed and the cards have been
encoded in the Admin/Card Holders screen of the SMS software. The reader supports the first two card
formats presented. If the two cards are the same type, only one format is supported.

Using the Reader

Present the proximity card face-on to the reader until you hear a "bleep". The maximum read range is
typically 0.4" (10mm). If the green indicator is lit, the card has been accepted and the door is unlocked.
If the red indicator is lit, either the card has not been accepted, or you do not have access through the
door. If the red and green indicators flash alternatively, please wait.

Note: cards can be presented in rapid succession - there is no need to wait for the green or red LED to
extinguish before presenting another card.
