ELK Products ELK-M1DBH M1 Data Bus Hub
Overview
The ELK-M1DBH is a data bus hub designed to extend communication range and capacity on ELK M1 control panel systems. It acts as a repeater and signal booster on the M1 data bus, allowing you to deploy sensors, keypads, and peripheral devices at greater distances from the main panel than a direct connection would support. This solves the real-world problem of reaching devices in large facilities or installations where the main panel's native bus range falls short — without requiring additional wiring runs or signal degradation.
Compatibility
The ELK-M1DBH integrates directly with ELK M1 control panel systems, including the M1 base unit and all M1-compatible peripheral modules. It connects to the M1 data bus and is compatible with ELK M1 keypads, sensors, output modules, and other devices that communicate over the M1 protocol. Verify your specific M1 firmware version and any existing expansion modules before adding the hub, as bus topology may affect placement and performance.
Installation Notes
Mount the M1DBH in a central location relative to the distributed devices you intend to reach — closer to the midpoint between the main panel and furthest endpoint reduces signal loss. Connect it to the M1 data bus using the standard M1 terminal block or connector; power requirements and wiring gauge should match your ELK system documentation. The hub has no moving parts and requires no active cooling, making it suitable for closets, utility areas, or mounted on the panel itself if space allows. Do not install in wet or corrosive environments unless the unit is enclosed in a protective cabinet.
