S821 Contactless Smart Card Wall Switch Reader
The S821 is designed for mounting on most standard electrical backboxes for ease
of installation.
The S821 Contactless Smart Card Reader is able to read both Texas InstrumentsTM
(ISO 15693) smart cards, and the card serial number on Philips® MIFARE® smart cards.
For either type of card, the S821 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 G4Tec’s own "smartMAX" format.
The S821 can be connected to G4Tec’s multiNODE-1000, multiNODE-2 SMD, multiNODE-2000
and multiNODE-2100 controllers and is compatible with G4Tec's Symmetry Business, Symmetry Professional,
Symmetry Enterprise and Symmetry Global Software at Version 4.0 and later.
Unlike Wiegand interface readers, the S821 uses secure, bi-directional, Pseudo-
Random supervised communications between the multiNODE controllers and their associated
readers. An alarm will sound if communications are lost.
A distance from any of the multiNODE controllers to the S821 reader of up to 3000ft
(1000m) can also be achieved.
The S821 has a maximum read range of up to 3" (75mm).
Other key reader features include LEDs for visual indication of card accepted
or card rejected and an integrated buzzer for card read and door pre-held warning.
The S821 Wall Switch Contactless Smart Card Reader is very cost effective and comes
with exceptional reliability and consistent read range characteristics.
The S821 has fully potted electronics and is ideal for both outdoor and indoor use
and is warranted against defects in workmanship for life (see our warranty policy
for details).
