Lenel Lnl3300m5 Installation Manual Upd Top __hot__ May 2026

In Lenel documentation, "UPD" often refers to a specific hardware revision or is a typo for "Update," but most commonly users searching for this combination are looking for the "Overlay" board installation which sits on top of the main board, or the physical mounting of the board within the enclosure.

Here is the relevant installation information extracted from standard Lenel LNL-3300M5 technical guides regarding the top assembly and terminal connections.

1. What is the LNL-3300?

The LNL-3300 is a two-door/dual-reader interface module for Lenel’s OnGuard access control system. It connects to an LNL-500 or LNL-1000 Intelligent System Controller (ISC) via RS-485. lenel lnl3300m5 installation manual upd top

The “Top” in lenel lnl3300m5 installation manual upd top refers to top-level system architecture. The M5 is a true IP controller, not a serial gateway.

2. "UPD Top" Installation Overview

The "UPD Top" usually refers to mounting the magnet to the underside of the header (top of the door frame) rather than the face of the frame. In Lenel documentation, "UPD" often refers to a

For Deep Frames/Doors: If you have a deep door or frame profile, the manual typically instructs the following to ensure the armature aligns correctly with the magnet:

  1. Positioning the Magnet:

    • Place the LNL-3300M5 magnet body against the underside of the door header.
    • Ensure it is set back far enough so the armature (on the door) will engage fully without hitting the door stop.
    • Critical Step: For "deep" installations, verify that the wiring conduit (the wire lead exit point on the magnet) does not interfere with the door movement. On top mounts, wires typically feed through a hole drilled in the header.

  2. Mounting the Armature:

    • The armature must be centered on the door top.
    • Deep Piece Adjustment: If the door is exceptionally thick or has a deep top rail, ensure the armature mounting screws (usually supplied with spacers or rubber grommets) allow the plate to "float" slightly. This flexibility is required for the magnet to pull the armature tight against the face of the lock.
    • Alignment: The armature must be perfectly parallel to the magnet face. If the door hangs "deep" in the frame, you may need to use the provided shim spacers behind the magnet to extend it out to meet the armature.
