LenelS2 LNL-1320-S3 Series 3 Dual Reader Interface Module

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. Backed by our 1-year hardware guarantee.
