G4S Technology S843B, S843A User Manual

Installation and User Instructions for S843 Readers

The S843 is a
keypad, which uses p
communications
and Philips MIFARE DESfire smart cards.

For either type of card, the S843 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.

1

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 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).

2

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.

Note: The FERRITE must be fitted!
Slide the ferrite sleeve onto cable before wiring terminal block. Ferrite to be placed 50mm (2") up cable
and held in place with cable ties.

Reader Configuration

5

The reader supports the first two different card types/formats presented after power-up. For example,
encoded MIFARE and encoded MIFARE DESfire (in this example, unencoded cards would not be
recognized). The reader enters this configuration mode whenever power is re-applied.

A reader Setup menu can be displayed by pressing the * and # keys simultaneously while power is
applied. You can use the menu to change the contrast and language used for the LCD (default English),
and view the two card types/formats previously programmed. At the prompts, press * for No and # for Yes.

Using the Reader

6

Present the card face-on to the reader until you hear a "bleep". Cards can be presented in rapid succession;
there is no need, for example, to wait for "UNLOCKED" to disappear before presenting another.

If the reader has been enabled for user-code mode at the controller, you can gain access by pressing the #
key, entering your card number, then pressing the * key.
