Two Doors On Board, 64 Doors in Total
Two reader ports, eight supervised inputs and four Form-C relays run two doors directly. Two downstream RS-485 ports add up to 64 devices, including LNL-1100, LNL-1200, LNL-1300 and LNL-1320 modules, Schlage PIM-400 wireless interfaces (OnGuard 7.5 and higher) and ASSA ABLOY Aperio wireless devices.
BACnet Building Integration
Through OnGuard, up to 63 BACnet points can be defined as a mix of physical inputs and virtual outputs. A BACnet client can set and read the virtual outputs, giving two-way state exchange with HVAC, lighting and other building systems.
Cybersecurity and Credentials
TLS 1.2/1.3 to OnGuard, AES-256 to LenelS2 Series 3 reader and I/O modules (AES-128 for Series 2), OSDP Secure Channel and an optional data-at-rest encryption setting. Optional onboard FIPS-201 authentication is available with HID pivCLASS or Technology Industries EntryPoint, and biometric templates (ANSI/INCITS 378) can be stored on the controller.
Readers and Power
Reader ports support Data1/Data0, Clock/Data, unsupervised F2F and OSDP RS-485 readers and keypads, with up to 600 mA per reader. The board runs from 12 to 24 VDC ± 10% at 550 mA plus reader current.
Typical Applications
- Enterprise headquarters and multi-building campuses
