Access Control
LNL-1320 Series 2
Lenel Systems International offers a Dual Reader Interface (DRI) module for access control
solutions. Most access control card readers, keypads, or readers with keypads that use standard
Wiegand Data1/Data0 or Clock/Data communication are supported, as are those that support 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 DRI. Each DRI supports up to
eight different card formats as well as issue codes for both magnetic and Wiegand card formats.
The DRI provides a vital link between the Intelligent System Controller (ISC) and the card reader
attached to the interface. As many as 32 DRI modules can be multidropped using RS-485 2-wire
or 4-wire communication up to 4,000 feet per port away from the ISC. Each DRI module is
individually addressed for increased reporting capabilities with OnGuard access control software
applications. The DRI includes eight inputs that support normally open, normally closed,
supervised, and non-supervised circuits. In addition, six output relays support fail-safe or
fail-secure operation.
