G4S Technology S831 User Manual

Installation and User Instructions for S831 Readers

The S831 is a small-footprint contactless smart-card
reader, which uses p

communications

Instruments (ISO 15693) and Philips MIFARE smart
cards.

For either type of card, the S831 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 TI" format.

The reader can simultaneously support two different card
types/formats (e.g. "smartMAX TI" and MIFARE). The
reader is automatically configured to accept the first two
card types/formats presented.

Using the Reader

Present the proximity card face-on to the reader until you hear a "bleep". 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.

cards can be presented in rapid succession - there is no need to wait for the green or red

Note:
