Linear EL36-4MP 620-100258P Elite-36 Power Distribution System Details
The Linear / Nice EL36-4MP is an eMerge e3 Elite-36 primary access control system configured for 4 controlled doors and up to 8 readers. It combines the Elite controller, embedded access control software, browser-based administration, Ethernet networking, a locking metal cabinet, an integrated tamper switch, and a power distribution system in one commercial assembly.
The EL36-4MP is designed for commercial and institutional properties that need centralized credential management, access schedules, door monitoring, event reporting, remote administration, and a path for future multi-door expansion.
What the EL36-4MP Does
- Controls 4 doors in its supplied hardware configuration.
- Supports up to 8 readers for entry-only or entry-and-exit applications.
- Supports up to 20,000 cardholders and 80,000 cards according to the product-specific manufacturer page.
- Provides browser-based management through an embedded web server.
- Uses an embedded Linux operating system.
- Supports compatible Elite license upgrades.
- Works with select EXN expansion nodes and ACM add-on door modules.
- Provides integrated power distribution for properly selected field equipment.
Compatible System Family
The EL36-4MP is a primary controller for select Linear / Nice eMerge e3 Elite systems. It may be used with compatible Elite expansion licenses, networked EXN expansion nodes, and ACM modules when supported by the controller generation, firmware, cabinet arrangement, and system design.
Commonly associated expansion products include select EXN-2M, EXN-2MP, EXN-4M, EXN-4MP, ACM2D, ACM2DP, ACM4D, and ACM4DP assemblies. These are related expansion products, not guaranteed replacements for the EL36-4MP.
Four-Door and Eight-Reader Configuration
The controller is ready to connect 4 controlled openings and up to 8 readers. A system may use one reader per door for entry-only access or two readers per door for read-in and read-out operation when supported by the project wiring and programming.
Readers and credentials must match the required frequency, credential technology, card format, reader interface, operating voltage, and current capacity. Similar-looking 125 kHz, 13.56 MHz, Bluetooth, Wiegand, and other reader products are not automatically interchangeable.
Integrated Power Distribution System
The final "P" identifies the power distribution cabinet and module configuration. Current Nice/Linear documentation describes the following power functions:
- 4 individually selectable 12V or 24V auxiliary outputs.
- PTC resettable output protection.
- 2 individual access controller power outputs.
- Battery charging for up to two 7 Ah batteries.
- Fire release input for properly engineered fire alarm integration.
- AC-failure and low-battery notification.
- Field expansion from 4 to 8 powered outputs with the applicable upgrade kit.
A current e3 family brochure describes the Elite power distribution option as using an integrated 10A supply with step-up regulation for simultaneous 12VDC and 24VDC requirements. Confirm the exact installed supply model, available current, output allocation, and cabinet label before calculating the field-device load.
Important Part Number and Suffix Warning
Model EL36-4MP is associated with part number 620-100258P. The final "P" must not be omitted because it identifies the power distribution version.
Part number 620-100258 without the final "P" is associated with the EL36-4M standard metal cabinet. A model ending in "B" identifies a reader-bundle configuration. Because EL36-4MP does not end in "B," readers should not be assumed included.
Expansion Capacity Warning
The product-specific Nice/Linear description identifies the EL36-4MP as a 4-door system that can be expanded to 36 doors and 72 readers with applicable license keys and expansion nodes. The same product page also references broader Elite expansion to 128 doors and 256 readers.
A newer manufacturer brochure states that Elite systems ship beginning with a 36-door license. These statements do not fully agree with the product-specific 4-door description. Confirm the actual license stored in the controller, firmware generation, supported upgrade licenses, and approved expansion architecture before planning beyond 4 doors.

- Verify the planned final door and reader capacity.
- Confirm reader technology, Wiegand format, credential frequency, and current draw.
- Confirm lock voltage, lock current, and fail-safe or fail-secure operation.
- Calculate the complete controller, reader, lock, relay, and auxiliary load.
- Verify the installed power supply model and total available current.
- Confirm battery voltage, capacity, quantity, terminal type, and cabinet fit.
- Determine whether the 4-to-8-output power upgrade kit is required.
- Verify Ethernet settings, firmware, browser access, and cybersecurity requirements.
- Confirm fire release, emergency egress, request-to-exit, and door monitoring requirements.
Installation and Service Notes
The EL36-4MP should be installed and commissioned by a qualified access control or low-voltage technician. The technician must verify incoming power, grounding, output voltage selection, battery charging, reader wiring, relay loads, lock power, network configuration, system licensing, and expansion-node communication.
Do not bypass fire alarm release circuits, emergency egress hardware, request-to-exit devices, door position monitoring, or other required life-safety functions. High-voltage branch wiring and internal power supply service should be completed only by properly qualified personnel.
Product Questions and Answers
Is the Linear EL36-4MP supplied as a 4-door system?
Yes. Model EL36-4MP, part number 620-100258P, is identified as an Elite-36 system configured for 4 doors and up to 8 readers. Verify the actual installed license when servicing an existing controller.
What does the final "P" in EL36-4MP mean?
The final "P" identifies the power distribution cabinet and module configuration. Part number 620-100258 without the final "P" is associated with the EL36-4M standard cabinet.
Does part number 620-100258P include access control readers?
Readers should not be assumed included. EL36-4MP does not have a "B" reader-bundle suffix, so compatible readers and credentials normally must be selected separately.
Can the EL36-4MP provide both 12V and 24V power?
The power distribution section provides 4 auxiliary outputs that can be individually selected for 12V or 24V. The installer must verify the voltage and total current required by every connected device.
Are backup batteries included with the EL36-4MP?
Battery inclusion could not be fully confirmed. The power distribution system provides charging for up to two 7 Ah batteries, but the approved voltage, quantity, terminals, and package contents must be verified.
What is the difference between EL36-4MP and EXN-4MP?
The EL36-4MP is a primary Elite access control controller. The EXN-4MP is a networked expansion node that requires a compatible primary Elite controller and cannot serve as a direct standalone replacement.
Can the EL36-4MP be expanded beyond 36 doors?
Nice/Linear currently publishes both a 36-door product-specific expansion figure and a broader 128-door Elite capacity. Confirm the controller generation, firmware, installed license, and available upgrade licenses before planning beyond 36 doors.
What should be verified before ordering the EL36-4MP?
Verify part number 620-100258P, the installed door license, planned expansion, reader and credential format, lock voltage and current, power supply, batteries, fire release interface, network settings, firmware, and current package contents.
