The LNL-1320 Board
The LNL-1320 reader interface boards provide a solution to the host system
integrator for interfacing to a TTL (D1/D0, Clock/Data), F/2F, or 2-wire RS-
485 device and door hardware. The LNL-1320 provides a tri-state LED
control and buzzer control. Six (6) Form-C relay outputs may be used for
strike control or alarm signaling. Eight (8) inputs are provided that may be
used for monitoring the door contact, request to exit push button and alarm
contacts. Input circuits can be configured as unsupervised or supervised.
The LNL-1320 communicates to the controller via a 2-wire RS-485.
See the following diagram for component location (some components
shown are not present on the LNL-1320).
Supplying Power to the LNL-1320
The LNL-1320 accepts 12 to 24 VDC for power on TB7 (VIN and GND).
Locate the power source as close to the LNL-1320 as possible. Make power
connection with minimum of 18 AWG wires.
Observe POLARITY on VIN!
The VOUT terminal on TB7 is the same as VIN.
Communication Wiring (SIO Communication Port)
The LNL-1320 communicates to a Lenel intelligent controller (LNL-3300,
for example) via a 2-wire RS-485 interface. The LNL-1320 allows for
multi-drop communication on a bus of up to 4000 feet (1219 m). Use
twisted pair (minimum 24 AWG) with drain wire and shield for
communication. See Specifications section.
Install RS-485 termination jumper, J4, on the interface boards at each end of
the communication line only.
