Product Overview
The Linear EXN-2CB 620-100275 is a 2-door eMerge Elite expansion node bundle supplied in a compact enclosure with two proximity readers. It is designed to expand a supported eMerge Elite system from a separate node location instead of adding a plug-in module inside the main cabinet.
EXN nodes are useful when the added doors are away from the main access control cabinet or when the job layout calls for a local expansion enclosure. This bundle provides two reader ports, four inputs, four output relays, optional PoE support where used, and an integrated tamper switch.
The compact cabinet version saves space, but enclosure choice still matters. Verify whether the job calls for compact plastic or metal cabinet hardware, and confirm the included readers match the credentials used at the site.

Technician Note
For remote expansion, review network path and power method before ordering. Optional PoE can simplify some installations, but lock power, fire release, and local code requirements still need to be designed correctly.
Before Ordering
- Confirm the existing system supports EXN expansion nodes
- Confirm the required enclosure type is compact plastic, not metal cabinet
- Verify the reader format and existing credentials
- Check network availability at the node location
- Confirm PoE or local power requirements
- Review door contact, REX, lock relay, and fire release wiring
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 use this as a stand-alone controller without a compatible eMerge Elite system
- Do not confuse EXN-2CB with ACM2DB; they serve different installation layouts
- Compact enclosure parts should not be substituted for metal cabinet versions without project approval
Product Questions & Answers
What is the difference between EXN-2CB and ACM2DB?
EXN-2CB is a separate 2-door expansion node in its own compact enclosure. ACM2DB is a plug-in expansion module intended for supported eMerge cabinets.
Does EXN-2CB include readers?
Yes. The CB bundle version includes two proximity readers.
Can this node be mounted away from the main controller?
Yes. EXN nodes are designed for separate installation from the eMerge Elite-36 system enclosure when the system design supports it.
Does this provide lock power?
Lock power design depends on the installation. Confirm power supply requirements for electric strikes, maglocks, and fire release circuits separately.
What should be checked before replacing an EXN node?
Check the model number, enclosure type, reader count, wiring, network settings, power method, and system license before replacing the node.
