General

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. Input circuits can be configured as unsupervised or supervised. 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 Series 3 Hardware

Notes: Older versions of the LNL-1300 Series 3 do not include the OSDP termination jumper J602.

Diagrams include jumper and terminal block labels for all versions such as: J1/J601, TB2/TB501.

Supplying Power to the LNL-1300 Series 3

The LNL-1300 requires filtered 12 to 24 VDC ± 10% for power. Two (2) inputs are typically used for door contact and exit push button monitoring. End of line resistors are required input supervision, shown below.

Note: 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/TB701-6 (VO), is not current-limited.

J602 OSDP Termination Jumper

The J602 jumper is located next to the reader port and controls OSDP termination. This jumper should be closed when an OSDP reader is used. When using a non-OSDP reader, the jumper should be open.

Important: Failure to properly set the OSDP termination jumper could cause reader communication issues.

Note: Older versions of the LNL-1300 Series 3 do not include the OSDP termination jumper J602.

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.

Notes: For OSDP cable lengths greater than 200 ft (61 m) or EMF interference close jumper J602.

For older versions of the LNL-1300-S3 that do not include jumper J602, install a 120Ω +/- 2Ω resistor across RS-485 termination ends.

Data 0 and Data 1 wires for Wiegand may be reused for OSDP. However, standard Wiegand cable may not meet RS-485 twisted pair recommendations. The reuse of cable works best on shorter cable lengths at lower data rates.

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 circuit is 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.

Typical DC Door Strike Wiring

Diode Selection:

• Diode current rating: greater than 1x strike current.
• Diode breakdown voltage: 4x strike voltage.
• For 12 VDC or 24 VDC strike, diode 1N4002 (100V/1A) typical.

Communication Wiring

The LNL-1300 communicates with a LenelS2 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/J601).

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.
