Symmetry S884 Installation And User Instructions

Installation and User Instructions for S884 Readers
The S884 is a contactless smart-card reader, with Graphic LCD
and keypad. The reader can be set to use Wiegand or
current loop communications.
The S884 reader will read smartMAX encoded MIFARE cards
and card serial numbers from most ISO 14443A smart cards
which have a 4-byte UID (User Identification). The reader may
be configured to read other card types by presenting a
programming card to the reader during start up.
Mount the Backplate
1
Mount the backplate using countersunk headed screws
adjacent to the opening edge of the door and at a
convenient height (recommended height is 5' (1.5m) to top
of unit).
If fixing hole 'A' is used then the breakout must be removed
and the screw must not protrude.
Feed the required cables through the backplate:
The cable from the controller.
A cable from a External Reader (Optional).
General Purpose Input / Output cable (Optional)
If wall tamper function is to be used then breakout 'B' must
be removed and an appropriate wall screw fitted through
the hole to actuate the tamper lever.
The securing screws 'C' are integral to the backplate and are unscrewed via the small holes in the
enclosure so that the screw heads locate in the counterbored holes on the inside of the
enclosure.
