Overview of the LNL-2210
This controller provides a single door solution with either a single reader or two readers for ingress/egress
operation. It holds the database for the hardware configuration, and cardholder database in nonvolatile
memory. The event log buffer is stored in battery backed memory. The first reader port can accommodate
readers that utilize D1/D0, Clock/Data or OSDP 2-wire RS-485 electrical signaling, one or two wire LED
controls, and buzzer control (one wire LED mode only). The first reader port can also be used as a 2-wire
RS-485 interface which can be used to connect additional I/O boards. The second reader port can
accommodate readers that utilize D1/D0, Clock/Data, one or two wire LED controls, and buzzer control
(one wire LED mode only). Form-C relay outputs may be used for strike control or alarm signaling. The
relay contacts are rated at 2A @ 30 VDC, dry contact configuration. Inputs are provided for monitoring the
door contact, exit push button, or alarm contact. The controller requires either 12 VDC for power or Power
over Ethernet (PoE).
The intelligent single door controller may be mounted in a UL Listed 3-gang switch box; a mounting plate is
supplied with the unit. The controller may be mounted in an enclosure; the supplied mounting plate has
mounting holes that match the LNL-1300 mounting footprint.
Note:
This product has been evaluated by UL for access control applications only.
23.1
The LNL-2210 Board
The board contains the following components: one (1) host Ethernet interface, one (1) power-in input, two
(2) unsupervised/supervised inputs, two (2) reader interfaces, two (2) output relays, four (4) DIP switches,
seven (7) jumpers, seven (7) status LEDs, and one (1) reset switch.
Note:
The intelligent single door controller does not have a real-time clock. Therefore, you will need
to synchronize the time for this device whenever there is an extended power loss, or firmware
download. This can be accomplished by bringing the panel online with the OnGuard
Communication Server. Alternatively, either keep the board powered up when transferring it to
or from the communication bus lines or use a different controller such as the LNL-2220 that
does have a real-time clock.
