Linear ES-4MP 620-100153P Essential Plus Power Distribution System Details
The Linear / Nice ES-4MP is an e3 Essential Plus browser-managed access control system configured for up to 4 controlled doors and 8 readers. This version combines the Essential controller, access control software, locking metal enclosure, supervised battery-backup provisions, and a power distribution system in one commercial assembly.
The system is designed for small and midsized commercial access control applications where authorized personnel need to manage cardholders, credentials, schedules, access levels, door activity, alarms, and reports through a network-connected web browser.
What the ES-4MP Does
- Controls up to 4 access-controlled doors.
- Supports up to 8 readers for entry-only or entry-and-exit applications.
- Provides up to 12 system inputs and 8 outputs.
- Manages up to 1,000 cardholders and 8,000 credentials.
- Provides embedded browser-based system programming and monitoring.
- Includes a metal cabinet with supervised AC and battery-backup provisions.
- Adds a power distribution system for properly selected locks and auxiliary devices.
- Provides a software upgrade path to higher-capacity e3 Elite systems.
Compatible Applications
The ES-4MP may be used for select commercial, industrial, banking, medical, retail, office, hospitality, warehouse, and institutional access control installations requiring as many as 4 controlled openings.
The system may be connected to properly selected access control readers, credentials, door position switches, request-to-exit devices, lock relays, electric locking hardware, and auxiliary equipment. Exact compatibility depends on reader protocol, credential technology, card format, voltage, current draw, relay configuration, wiring, and system programming.
Four-Door and Eight-Reader Capacity
The ES-4MP is the 4-door Essential Plus configuration. It supports up to 8 readers, allowing an entry reader and an exit reader to be assigned to each controlled opening when required by the project design.
The Essential platform supports up to 12 inputs and 8 outputs. These connections must be assigned and programmed for door contacts, request-to-exit devices, lock relays, alarm inputs, and other approved access control functions.
Power Distribution System
The final "P" in ES-4MP identifies the power distribution cabinet and module configuration. Current Nice/Linear power distribution documentation describes the following 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 designed fire alarm integration.
- AC-failure and low-battery notification.
- Field upgrade capability from 4 to 8 powered outputs with the applicable upgrade kit.
The exact power supply model and total available amperage for the current ES-4MP package should be confirmed before calculating field-device capacity. Do not assume that every lock, reader, relay, or accessory can be powered from the cabinet without completing a load calculation.
Important Part Number and Suffix Warning
Part number 620-100153P corresponds to model ES-4MP. The final "P" identifies the power distribution configuration. Part number 620-100153 without the final "P" is associated with the ES-4M standard metal cabinet.
The model does not have a "B" suffix, so readers should not be assumed included. Confirm the complete model, part number, cabinet configuration, license, and package contents before ordering.

Similar Parts Are Not Automatically Interchangeable
The ES-4MP may resemble other e3 metal cabinets, but controller role, licensing, database capacity, power equipment, included modules, firmware, and expansion capability may differ.
Do not substitute an ES-4M, EL36-4MP, EXN-4MP, or ACM4DP based only on cabinet appearance or 4-door capacity. Verify the full part number and the current system parts diagram.

Installation and Service Notes
The ES-4MP should be installed and commissioned by a qualified access control or low-voltage technician. The technician must verify incoming power, grounding, battery charging, reader wiring, lock power, relay operation, network configuration, and fire alarm integration.
Do not bypass fire release circuits, emergency egress hardware, request-to-exit devices, door 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 ES-4MP configured for four doors?
Yes. Model ES-4MP, part number 620-100153P, is the e3 Essential Plus 4-door configuration and supports up to 8 readers.
What does the final "P" in ES-4MP mean?
The final "P" identifies the power distribution cabinet and module configuration. The ES-4M without the final "P" uses the standard metal cabinet.
Does the ES-4MP include access control readers?
Readers should not be assumed included. The ES-4MP does not have the "B" reader-bundle suffix, so compatible readers and credentials normally must be ordered separately.
Can the ES-4MP provide both 12V and 24V power?
The power distribution system 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 part number 620-100153P?
Battery inclusion could not be fully confirmed. The power distribution system supports charging for up to two 7 Ah batteries, but the approved voltage, quantity, terminals, and package contents must be verified before ordering.
What is the difference between the ES-4MP and EXN-4MP?
The ES-4MP is a primary Essential Plus access control system. The EXN-4MP is an expansion node for a compatible e3 Elite primary controller and is not a direct replacement for the ES-4MP.
Can the ES-4MP be upgraded to an e3 Elite system?
Yes. Nice/Linear provides a software-based Essential-to-Elite upgrade path. Confirm the required license, firmware, hardware condition, and planned door capacity before ordering the upgrade.
What should be verified before installing the ES-4MP?
Verify the 4-door license, readers, credentials, lock voltage and current, power supply model, total load, batteries, network settings, fire release interface, emergency egress hardware, and current package contents.
