The LNL-1100 Board

The LNL-1100 processor provides a solution to the host system integrator for sensor monitoring and output control. The LNL-1100 has 16 non-supervised or supervised inputs and two (2) form-C contact relays for load switching. In addition, two (2) digital inputs are used for cabinet tamper and power fault status monitoring. The processor requires 12 to 24 VDC for power.

Supplying Power to the LNL-1100

The LNL-1100 accepts 12 to 24 VDC for power. Locate power source as close to the unit as possible. Connect power with minimum of 18AWG wires.

Observe POLARITY on VIN!

The VOUT terminal on TB11 is the same as VIN.




Communication Wiring

The LNL-1100 communicates to an intelligent controller (for example, the LNL-3300) via a 2-wire RS-485 interface. The interface allows multi-drop communication on a single bus of up to 4000 feet (1219 m). Shielded cable of 24 AWG with characteristic impedance of 120 ohm is specified for the RS-485 interface. See Specifications section.

Install RS-485 termination jumper, J3, on the interface boards at each end of the communication line, only.

ONLY 2-WIRE RS-485 IS SUPPORTED.

Alarm Inputs Wiring

Inputs 1 to 16 can be configured to use or not use End Of Line (EOL) resistors and to use normally open or normally closed contacts. Input CT and input BA are used for monitoring cabinet tamper and power failure, respectively. These two (2) inputs are for contact closure monitoring only, and do not use EOL resistors.

Input configuration is set via the host software.

Relay Outputs

Two (2) form-C contact relays are provided for controlling door strikes or other devices. 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 [30cm]) as the effectiveness of the circuit will decrease if it is located farther away.

Use sufficiently large gauge of wires for the load current as to avoid excessive voltage drop.

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