Description
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.
