is an Intelligent System Controller (ISC) designed specifically for the OnGuard® system. It serves as a plug-compatible, Mercury-based hardware replacement for legacy CASI M5 and M3000 boards, facilitating a modern migration path for systems like Picture Perfect, FCWnx, and Secure Perfect. 1. Pre-Installation Preparation
Before beginning, ensure you have the following requirements and tools: Operating Voltage: 12 VDC ± 10% at approximately 300mA.
Backplane Compatibility: The board is designed to retrofit into legacy CASI M5/M3000 enclosures.
Connectivity Hardware: A standard Cat5/6 cable for Ethernet and shielded twisted pair (24 AWG) for RS-485 downstream communication.
System Software: OnGuard software must be licensed and configured for the LNL-3300 series.
Important Note: Legacy CASI M Series boards cannot be mixed with Lenel M Series boards in the same controller; if you convert a controller, all boards within it must be upgraded to the Lenel M Series. 2. Physical Installation Steps To install or migrate to the LNL-3300-M5 Lenel Lnl-3300-m5 Installation Manual UPD
Power Down: Completely power down the legacy controller and disconnect the backup battery.
Unplug Wiring: Label and unplug the field wiring and the power/comm board connectors from the legacy CPU.
Remove Old Board: Unscrew and remove the legacy M5/M3000 CPU (e.g., E, P, PX, PXN, or PXNplus) and the CASI Power/Comm Board (PN: 110064001). Insert LNL-3300-M5
: Mount the new board onto the existing standoffs in the enclosure.
Reconnect Wiring: Plug in the 12 VDC power input, cabinet tamper input, and AC power fail inputs. The LNL-3300-M5 is one-for-one plug compatible with these connections. 3. Initial Configuration & IP Setup LNL-3300-M5 - Stebilex Systems
7. Wiring inputs and outputs
- Supervised inputs: Wire door contacts, motion sensors, and tamper switches using supervised tamper-resistant pairs; install end-of-line resistors as specified for supervision.
- Request-to-exit (REX): Wire REX devices (push buttons, PIR REX sensors) to designated inputs; configure debounce and timing in OnGuard.
- Relay outputs: Connect locks, strike power, mag-locks, and auxiliary devices to relay outputs; use appropriate suppression diodes or TVS for inductive loads.
- Reader power: Provide reader power from supervised reader outputs; if using external power supplies, ensure supervision and correct wiring to the module.
- Grounding and shields: Tie cable shields to chassis ground at one end only; avoid ground loops.
Unboxing & Mounting
- Mount the controller inside an appropriate metal enclosure with sufficient clearance for cabling and airflow.
- Secure to a wall or rack using supplied standoffs/holes.
- Keep the controller away from excessive heat, moisture, or electromagnetic interference.
🛠️ Quick Installation & Wiring Notes
If you are deploying one of these for the first time, here are a few things the manual assumes you already know: Lenel LNL-3300-M5 Installation & Migration Guide The Lenel
- RS-485 Wiring Topology: The LNL-3300-M5 connects to the OnGuard system via a buffered RS-485 port (LNLR-42x or LNL-1100 series). Do not daisy-chain these in a "star" topology. Keep it a straight bus.
- Dip Switch Settings: This is where most people trip up. The manual covers the addressing, but double-check your baud rate settings.
- Tip: If the reader isn't communicating, verify the RS-485 polarity (+/-). It sounds basic, but the labels on some legacy harnesses can be confusing.
- Multi-Technology Output: This board is a beast because it can handle OSDP (Open Supervised Device Protocol) and Wiegand simultaneously. If you are upgrading legacy readers to OSDP, remember you have to cut the Wiegand wires and re-terminate unless you are running hybrid mode.
- Power Requirements: Don't forget that the LNL-3300-M5 does not power the readers. You need a separate power supply (like the LNL-500 or a third-party UL listed supply) if your readers don't have local power.
2. Key Changes in the Updated Manual
Conclusion
The Lenel Lnl-3300-m5 Installation Manual UPD is not just a minor revision; it is a mandatory read for anyone integrating this controller into a modern IP access control system. The updates to PoE, OSDP wiring, and cybersecurity defaults reflect the industry's shift toward smarter, safer installations.
Always keep a copy of the latest manual in your service vehicle. A failed installation caused by referencing a Rev 4.0 manual when you have a Rev M5 board will cost you more in truck rolls than the price of the hardware.
