Used: fully function-tested before shipping. We visually inspect the board, load the approved firmware for the listed platform when applicable, power it at rated input, verify applicable inputs, outputs, relays, and communications on a test fixture, complete the documented burn-in procedure, and record the serial number before packing.
The LenelS2 LNL-1320-S3 is a Series 3 dual reader interface module (DRI) that expands a Lenel OnGuard access control system, adding two doors' worth of reader, input, and output capacity downstream of a Lenel intelligent controller such as the LNL-X3300. It connects to the master controller over a 2-wire RS-485 bus supporting multi-drop communication up to 4,000 ft (1,219 m), so you extend door capacity across a facility without home-running every reader back to the panel. Each of its two reader ports accepts TTL (D1/D0, clock/data), F/2F, or 2-wire RS-485/OSDP signaling, with selectable 12 VDC or pass-through reader power, and supports up to 16 card formats plus lock, unlock, and facility-code offline access modes. For OSDP readers it provides AES 128-bit encryption over OSDP Secure Channel, including biometric template transfer. Eight supervised inputs monitor door contacts, request-to-exit buttons, and alarm points, while six Form-C relay outputs drive strike control or alarm signaling.
