G4S S844 Installation And User Instructions

Installation and User Instructions for S844 Readers
The S844 is a contactless smart-card reader, with LCD and
keypad. The reader can be set to use Wiegand or
current loop seudo-random communications. p
The S844 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 S844 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.
Note: For PIV II compliance, Wiegand communications should
be used.
Fit the Weatherproofing Kit
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 Mount the Backplate
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.
3 Reader Links
Set LK1 (USER FB) to 1 for sound on, or 0 for sound off. If a jumper is provided for LK2 (TEST), park it
across one pin only. Set LK3 (COMMS) across the center and WGD pin for Wiegand communications, or
across the center and C/L pin for 20mA current loop communications.
