Linear EXN-2M, 620-100279 eMerge Elite 2-Door EX Node w/ Standard Cabinet
The Linear EXN-2M 620-100279 is a 2-door eMerge Elite expansion node in a locking metal cabinet. It adds two reader ports, four inputs, and four output relays to a supported eMerge Elite system from a separate expansion node location.
This is the metal-enclosure version without the included reader bundle. It is commonly used when the job needs a more serviceable or secure cabinet, or when readers are already specified separately. The metal cabinet with integrated tamper switch is often preferred in equipment rooms and commercial access control closets.
EXN-2M should be ordered by model and enclosure requirement. It is not the same as EXN-2MB, which is the bundled version with readers, and it is not the same as an ACM module that mounts inside the main controller cabinet.

Technician Note
Use EXN-2M when the job calls for a separate 2-door node in a metal cabinet. If the customer expects readers to be included, confirm whether EXN-2MB is the correct bundled item instead.
Before Ordering
- Confirm the eMerge Elite system supports EXN nodes
- Confirm the job requires a metal cabinet instead of compact plastic
- Verify whether readers are needed separately
- Check network connection and power method at the node location
- Confirm inputs, relays, and lock power requirements
- Confirm license and expansion capacity before installation
Professional Advisory
Access control panels and expansion modules should be installed and serviced by qualified access control or low-voltage technicians. Do not bypass door position inputs, request-to-exit devices, locking hardware safety requirements, fire release requirements, or local code requirements.
Important Ordering Warnings
- EXN-2M does not indicate included readers; do not assume it is a reader bundle
- Do not confuse EXN-2M with EXN-2MB or EXN-2CB
- Not a direct replacement for an ACM module mounted inside a main cabinet
