The Dual Door Controller (DDC) provides a solution for interfacing to Wiegand Data1/Data0 and Magnetic Clock/Data readers or keypads (4/8 bit), and door hardware. It can accept data from a reader with clock/data, Wiegand signaling, or 2-wire RS-485 (OSDP), and provides a tri-stated LED control and buzzer control. Six form-C relay outputs may be used for strike control or alarm signaling. Eight (8) inputs are provided for monitoring the door contact, exit push button, and auxiliary inputs (supervised or unsupervised). Communication to the host controller and other modules is done via a 2-wire RS-485 interface. It requires 12 to 24 VDC for power.DDC board (Dimensions are in inches [mm])83.1Package ContentsLNL-1320-U board1000 ohm resistorsrevision 6 — 407LNL-1320-U Dual Door Controller Module84InstallationTo install the Dual Door Controller (DDC), perform the installation procedures described in the following sections, in the order in which they are presented.
