Linear EXN-2MB, 620-100280 eMerge Elite 2-Door EX Node Standard Cabinet 2-Reader
The Linear EXN-2MB 620-100280 is a 2-door eMerge Elite expansion node bundle with a locking metal cabinet and two included proximity readers. It is built for adding two controlled doors to a supported eMerge Elite system from a separate node location.
This bundle is useful when the installer wants the durability and service access of a metal cabinet but also needs the reader hardware included with the expansion. It supplies two reader ports, four inputs, four output relays, optional PoE support where supported by the system, and an integrated tamper switch.
EXN-2MB is related to EXN-2M, but the MB bundle includes readers. Confirm the exact model suffix because the suffix often tells you whether the item is a module, enclosure, bundle, compact cabinet, or metal cabinet version.

Technician Note
If the site already has readers installed, EXN-2M may be the better match. If the project calls for a supplied two-reader expansion package in a metal cabinet, EXN-2MB is the more complete bundle.
Before Ordering
- Confirm the existing system supports EXN expansion nodes
- Confirm the bundle suffix MB is required, not M or CB
- Verify reader and credential format compatibility
- Check network and power method at the node location
- Confirm door hardware, REX, door contacts, and relay needs
- 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
- Do not confuse EXN-2MB with EXN-2M; the reader bundle differs
- Do not use an EXN node where the project specifies an ACM plug-in module unless the layout is revised
- PoE may not remove the need for proper lock power planning
Product Questions & Answers
What is included with the EXN-2MB?
It is a 2-door expansion node bundle in a metal cabinet and includes two proximity readers.
How is EXN-2MB different from EXN-2M?
EXN-2M is the metal cabinet node without the reader bundle, while EXN-2MB includes two readers.
Can this expand an eMerge Elite system by two doors?
Yes, when used with a supported eMerge Elite system, proper licensing, and correct network and power design.
Is PoE enough to power the locks?
Not by itself in many installations. Lock power and fire release requirements should be designed separately by the installer.
What should be matched before ordering?
Match the model suffix, enclosure type, reader format, door count, inputs, relays, system license, and existing eMerge platform.
