Intelligent Controller LNL-X4420 with Two Reader
Interfaces Quick Reference
General
The LNL-X4420 intelligent controller provides decision making, event reporting, and database storage for the Lenel
hardware platform. Two reader interfaces provide control for two doors.
The LNL-X4420 communicates with the host via on-board 10Base T/100Base-TX Ethernet port or the Micro USB
port (2.0) with an optional Micro USB to Ethernet adapter.
Two physical barriers can be controlled with the LNL-X4420. Each reader port can accommodate a read-head that
utilizes TTL (D1/D0, Clock/Data), F/2F or 2-wire RS-485 electrical signaling (OSDP reader for example) and also
provides tri-state LED control and buzzer control (one wire LED mode only). Four Form-C relay outputs may be
used for door strike control or alarm signaling. Eight inputs are provided for monitoring the door contacts, exit push
buttons, and alarm contacts. Input circuits can be configured as unsupervised or supervised. The LNL-X4420 requires
12 to 24 VDC for power.

(OSDP reader for example). Power to the readers is selectable: 12 VDC (VIN must be greater than 20 VDC), or power is passed-through (PASS) from the input voltage of the LNL-X4420 (TB1-VIN), 300 mA maximum per reader port. Readers that require different voltage or have high current requirements must be powered separately. - Page 6 When unsupervised, reporting consists of only the open or closed states.

Door lock mechanisms can generate feedback to the relay circuit that can cause damage and premature failure of the relay plus affect the operation of the LNL-X4420. For this reason, it is recommended that a diode be used to protect the relay. -

Upon installation, the user accounts to the web configuration page should be created with secure passwords, and that all DIP switches are in the OFF position for the normal operating mode. The LNL-X4420 is shipped from the factory with a default login account, which is enabled when DIP 1 is moved from OFF to ON. The default login user name and password will be available for five minutes once enabled. -
