LenelS2TM offers a Single Reader Interface (SRI) module
for access control solutions. Access control card readers,
keypads, or readers with keypads that use standard Wiegand
Data1/Data0, Supervised or Unsupervised F2F, or Clock/
Data communication are supported, as are those supporting
the bidirectional RS-485 Open Supervised Device Protocol
(OSDP™). Lock, unlock, and facility code offline access modes
are supported on all readers connected to the SRI. Each SRI
supports up to 16 different card formats as well as issue codes
for both magnetic and Wiegand card formats.
The SRI provides a vital link between the Intelligent System
Controller (ISC) and the card reader attached to the interface.
As many as 32 SRI modules can be multidropped using RS-485
2-wire communication up to 4,000 feet (1219 m) per port
away from the ISC. Each SRI module is individually addressed
for increased reporting capabilities with OnGuard® access
control software applications. The SRI includes two inputs
that support normally open, normally closed, supervised, and
non-supervised circuits. Two output relays support fail-safe or
fail-secure operation
