Lenel Lnl-3300-m5 Installation Manual Upd Jun 2026

Always wear a grounded static-dissipative wrist strap while handling the board to prevent latent component damage.

Step 1: Preparing the EnclosurePower down the existing legacy controller. Label every wire connected to the terminal blocks before removal. Once labeled, disconnect the wiring and remove the old board from the enclosure.

LED Diagnostics: If the Status LED is solid red, there is a memory or processor error. If the Comms LED is not flashing, check the Ethernet cabling and the OnGuard communication server status. Lenel Lnl-3300-m5 Installation Manual UPD

The Lenel LNL-3300-M5 is a robust solution for facilities looking to move away from legacy CASI systems while retaining their original investment in wiring and enclosures. Following this manual ensures a smooth transition to the high-performance OnGuard platform. Share public link

Run 18 AWG twisted-pair wiring from the system power supply to the 12 VDC input terminals. Always wear a grounded static-dissipative wrist strap while

: The controller is typically shipped with an insulator installed between the battery holder and the battery. This insulator must be removed after installation. Reinstall the insulator if the controller will be stored for an extended period. Compatible battery types include:

The M5 series boards are engineered for a plug-and-play installation into existing enclosures: LNL-3300-M5 board directly over the M5/M3000 backplane slot. Once labeled, disconnect the wiring and remove the

: Reconnect the field wiring to the new board. The LNL-3300-M5 communicates through the existing M5/M3000 backplane to Reader Panels (RP) and I/O boards.

Plug a standard Cat5e/Cat6 patch cable directly into the RJ-45 network port. This establishes a direct connection to your OnGuard host server network.

The Lenel LNL‑3300‑M5 remains a capable and reliable intelligent system controller for organizations running OnGuard‑based access control systems, even as it enters its end‑of‑life phase. With its plug‑compatible design for legacy CASI hardware, onboard Ethernet connectivity, robust local database, and support for AES‑128 encryption, the LNL‑3300‑M5 provides a cost‑effective upgrade path for existing security infrastructures.

Once the physical hardware is installed and powered on, use the following steps to bring the controller online inside OnGuard:
