Symmetry™ S820 Proximity Wall Switch Reader
System Overview
The Symmetry S820 Proximity Wall Switch Reader reads HID 125KHz proximity cards and is designed for
mounting on most standard electrical backboxes for ease of installation.
The Symmetry S820 can be connected to the complete multiNODE range of database and
door controllers.
Unlike Wiegand interface readers, the Symmetry S820 uses secure, bidirectional, 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 Symmetry S820 reader of
up to 3000feet
(1000m) can also be achieved.
The Symmetry S820 has a typical read range of up to 3.5" (87mm) with HID Proxcard II.
The Symmetry S820 is available in three colors - ash gray, charcoal gray and black.
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 Symmetry S820 Proximity Wall Switch Reader is very cost effective and comes with exceptional
reliability and consistent read range characteristics.
The Symmetry S820 reader has fully potted electronics and is ideal for both outdoor and indoor
use.
The Symmetry S820 is warranted against defects in workmanship for life (see our warranty
policy for details).
