{"product_id":"lenel-lnl-x4420-same-day-shipping-sealed","title":"Lenel LNL-X4420 Dual Reader Controller","description":"\u003cp\u003eThe LNL-X4420 is an Advanced Dual Reader Controller that provides a single-board solution for interfacing up to 64 doors, plus auxiliary inputs and outputs, to an OnGuard® system. The LNL-X4420 controller enables Ethernet connection directly from an entry location to the OnGuard server. In addition, other I\/O and reader interface modules can be added on the controller’s two downstream ports, further expanding its capabilities. In the event of communication loss, the LNL-X4420 controller can maintain most of its local functionality until the server connection is restored. The LNL-X4420 controller can act as an interface to building automation systems via the ASHRAE BACnet™ protocol. Through the OnGuard software, up to 63 total BACnet points can be defined. These can be a mix of physical inputs connected to the board and virtual outputs. Virtual outputs can be set and read from a connected BACnet client, allowing two-way state exchange with a variety of building control systems. This information can be used by both OnGuard and the external system for status reporting, and as inputs to control logic.\u003c\/p\u003e\n","brand":"FIRE ALARM SYS","offers":[{"title":"Default Title","offer_id":51596092145984,"sku":"395259283143","price":1629.5,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0831\/6466\/0032\/files\/ec2eb02be61d3b11728c4d6d0a855483.jpg?v=1772740611","url":"https:\/\/firealarmsys.com\/products\/lenel-lnl-x4420-same-day-shipping-sealed","provider":"FIRE ALARM SYS","version":"1.0","type":"link"}
