Product Overview
The Linear ACM2DB 620-100270 is an eMerge Elite expansion access control module bundle for adding two readers, four inputs, and four outputs to a supported eMerge Elite-36 system. The bundle version includes two proximity readers, which makes it useful for expanding an existing access control cabinet while keeping the site within the same eMerge family.
ACM modules are different from EXN expansion nodes. An ACM is intended to plug into supported eMerge Elite systems mounted in the proper large or extra large cabinet, while EXN nodes are separate expansion nodes in their own enclosures. This difference matters when a technician is planning space, wiring, power, network layout, and future door count.
Use this module when the existing system documentation or controller cabinet calls for ACM2DB or 620-100270. Confirm that there is room in the enclosure and that the system license supports the added doors/readers.
Compatible With
- Select Linear eMerge Elite-36 systems with supported large or extra large cabinet configurations
- Existing eMerge Elite installations requiring 2 added reader ports, 4 inputs, and 4 outputs
- Projects where ACM2DB / 620-100270 is specified as the add-on module bundle
- Systems using compatible eMerge proximity readers supplied with the bundle
- Related eMerge Elite head-end systems that accept ACM add-on door modules with the correct license level
- Not a stand-alone access controller and not intended for unrelated Essential-only or non-eMerge panels

Technician Note
Order ACM modules by the existing cabinet layout and system license, not only by the number of new doors. If the expansion is remote from the main cabinet, an EXN expansion node may be the more appropriate product family.
Before Ordering
- Confirm the existing system is an eMerge Elite / Elite-36 system that accepts ACM modules
- Check that the cabinet is large enough and has available module space
- Confirm the added door count, reader count, inputs, and relay needs
- Verify credential format and reader compatibility
- Confirm licensing before adding doors
- Review power distribution and lock power needs
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
- ACM2DB is not a stand-alone controller
- Do not substitute an ACM module for an EXN node without checking the system layout
- Essential and Elite systems should not be mixed unless the manufacturer documentation supports the exact configuration
Product Questions & Answers
What does the ACM2DB add to an eMerge Elite system?
It adds 2 reader ports, 4 inputs, and 4 outputs to a supported eMerge Elite system and includes two proximity readers.
Can the ACM2DB be installed by itself?
No. It is an expansion module for supported eMerge Elite systems, not a stand-alone access control panel.
When would I use ACM2DB instead of an EXN node?
Use ACM2DB when the expansion module is intended to mount inside a supported main eMerge cabinet. Use an EXN node when a separate expansion enclosure is needed.
Does this module include readers?
Yes. The DB bundle version includes two compatible proximity readers.
What should be verified before ordering?
Verify Elite system compatibility, cabinet size, available module space, license level, reader format, and lock power design.
