Each reader port can accommodate a readhead that utilizes wiegand, magnetic stripe, or 2-wire RS-485 electrical signaling standards, one or two wire LED controls, and buzzer control (one wire LED mode only). Four form-c relay outputs may be used for strike control or alarm signaling. The relay contacts are rated at 5A @ 30 VDC, dry contact configuration. Eight supervised inputs are provided for monitoring the door contacts, exit push buttons and alarm contacts. Inputs can be configured to meet Grade A Supervision requirements. The LNL-2220 requires 12-24 VDC for power. It is recommended that the board be mounted 0.25 inch minimum above any conductive surface.28.1InterfacesThe IDRC interfaces upstream with the access control software on a host system.
