Linear EXN-4C, 620-100276 eMerge Elite Systems 4-Door EX Node w/ Compact Cabinet
The Linear EXN-4C 620-100276 is a 4-door eMerge Elite expansion node in a compact plastic enclosure. It adds four reader ports, eight inputs, and eight output relays to a supported eMerge Elite system from a remote node location.
This model is used when a project needs four additional doors but does not want to run all of the reader and door wiring back to the main cabinet. The compact enclosure helps where wall space is limited, while the integrated tamper switch supports monitored cabinet security.
EXN-4C does not indicate a reader bundle. If four readers are required with the node, compare against the EXN-4CB bundle. If the module must mount inside an existing main cabinet, compare against ACM4D instead.

Technician Note
Do not choose this part only because the site has four doors. Decide between EXN-4C, EXN-4CB, EXN-4M, EXN-4MB, and ACM4D based on enclosure type, reader bundle, cabinet location, and system design.
Before Ordering
- Confirm the existing eMerge Elite system supports EXN nodes
- Confirm compact plastic enclosure is acceptable for the job
- Verify whether readers are needed separately
- Check network and power method at the node location
- Confirm inputs, outputs, lock power, REX, and door contacts
- Verify expansion licensing and system capacity
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-4C does not indicate included readers
- Do not substitute EXN-4C for ACM4D without reviewing the installation layout
- Do not assume compact and metal cabinet versions are interchangeable for every project
Product Questions & Answers
Does the EXN-4C include readers?
No included reader bundle is indicated for EXN-4C. If readers are required, compare against the EXN-4CB bundle or order the correct readers separately.
How many readers does EXN-4C support?
It provides 4 reader ports for supported eMerge Elite expansion applications.
What is the enclosure type?
EXN-4C uses a compact plastic enclosure with an integrated tamper switch.
Is this the same as ACM4D?
No. EXN-4C is a separate expansion node, while ACM4D is a plug-in expansion module for supported main cabinets.
Where is this commonly used?
It is commonly used where four additional doors need to be controlled from a compact remote node location.
