The LNL-1300 Board

The LNL-1300 reader interface provides a solution to the host system integrator for interfacing to a TTL (D1/D0, Clock/Data) or RS-485 device, and door hardware. It also provides a tri-stated LED control and buzzer control. Two (2) Form-C contact relay outputs may be used for strike control or alarm signaling. Two (2) inputs are provided that can be used for monitoring the door contact and request to exit push button. Communication to the controller is accomplished via a 2-wire RS-485 interface. The LNL-1300 requires 12 to 24 VDC for power.

LNL-1300 Wiring

The LNL-1300 requires filtered 12 to 24 VDC ± 10% for power.

The input power is passed through to the reader terminal strip and is available for powering a reader. Readers that require different voltage requirements must be powered separately. Care must be taken to insure the input voltage is within the voltage range of the reader. The reader power output terminal, TB4-6 (VO), is not current-limited.

Alarm Input Wiring

Two (2) inputs are typically used for door contact and exit push button monitoring. These alarm inputs are connected using the I1 and I2 inputs. End of line resistors are required for input supervision, shown below.

Reader Wiring

The reader port supports a reader with TTL (D1/D0, Clock/Data) or 2-wire RS-485 signaling. (Refer to the reader manufacture specifications for cabling requirements.) In the 2-wire LED mode the buzzer output is used to drive the second LED. Reader port configuration is set via the host software.

Door Strike Relay Wiring

Two (2) Form-C contact relays are provided for controlling door strike or other devices. See Specifications section for the relay contact ratings. Load switching can cause abnormal contact wear and premature contact failure. Switching of inductive loads (strike) also causes EMI (electromagnetic interference) which may interfere with normal operation of other equipment. To minimize premature contact failure and to increase system reliability, a contact protection circuit must be used. The following two (2) circuits are recommended. Locate the protection circuit as close to the load as possible (within 12 inches [30 cm]), as the effectiveness of the circuit will decrease if it is located far away.

Communication Wiring

The LNL-1300 communicates to a Lenel intelligent controller (LNL-3300, for example) via a half-duplex, multi-drop 2-wire RS-485 interface. The total cable length is limited to 4000 feet (1219 m). A shielded cable of 24 AWG with characteristic impedance of 120 ohm is specified for the 2-wire RS-485 interface. The last device on each end of the communication line should have the terminator installed (install jumper J1).

Address, Baud Rate, and Encryption Configuration Switch

Switches 1 to 5 select the device address. Switches 6 and 7 select the communication baud rate. Switch 8 enables encrypted communication. All other configuration settings are set via the host software.
