Overview of the LNL-1300

Lenel offers a Single Reader Interface (SRI) module for business access control solutions. Access control
card readers, keypads, or readers with keypads that use standard data1/data0 and clock/data Wiegand
communications are supported. Lock/unlock and facility code, off-line access modes are supported on all
readers connected to the SRI. Each SRI supports up to 8 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 multi-dropped using RS-485 two-wire communication up
to 16,000 feet (4000 per port) away from the ISC. Each SRI module is individually addressed for increased
reporting capabilities with Access Control software applications. The SRI includes two (2) programmable
inputs that support normally open, normally closed, supervised and non-supervised circuits and two (2)
output relays support fail-safe or fail-secure operation.
The series 2 board differs slightly from the series 1 boards. Where series 2 is indicated, the information only
applies to series 2 boards. Otherwise, the information applies to both series 1 and 2 boards.
