Honeywell MPA4MPSU 4-Door MAXPRO Access Control Panel

The Honeywell MPA4MPSU is a 4-door MAXPRO Access control system with an integrated power supply, metal enclosure, and 12V backup battery designed for commercial access management. It supports up to 4 Wiegand entry readers or 8 OSDP entry/exit readers, with Ethernet, RS-485, and USB-C connectivity. The system features embedded web-based management, compatibility with MAXPRO Cloud and WIN-PAK software, 16 supervised inputs, 4 door control relays, and a built-in fire alarm interface for emergency door release.

Honeywell MPA4MPSU MAXPRO Access 4-Door Controller with Power Supply

The Honeywell MPA4MPSU is a complete 4-door access control panel featuring a MAXPRO Access controller, metal enclosure, integrated power supply, and battery backup for commercial and institutional security installations. The system manages electronic access to four controlled openings and supports 4 Wiegand entry readers or up to 8 OSDP readers configured for entry and exit control. Its integrated web-based management interface allows administrators to configure cardholders, access permissions, door schedules, and security events without requiring dedicated management software. The MPA4MPSU also supports Honeywell MAXPRO Cloud and WIN-PAK platforms for centralized access management across larger facilities and multiple locations.

The MPA4MPSU incorporates 16 configurable four-state supervised inputs, 4 single-pole double-throw (SPDT) door control outputs, and 4 auxiliary relay outputs for integration with electric locking devices, door position switches, request-to-exit devices, and additional security equipment. Door relay contacts are rated at 3 amps at 30 VDC through push-in terminal connections, while the auxiliary outputs provide additional programmable control capabilities. The system supports Wiegand and OSDP Version 2 reader communication, including 128-bit AES encrypted bidirectional communication for compatible OSDP readers. Host communications incorporate 256-bit AES encryption and TLS 1.2 to protect supported connections between the controller and its management platforms. An integrated supervised fire alarm input can override normal access control operation and place all four door outputs into a fail-safe condition to release compatible locking devices during emergency evacuation.

The Honeywell MPA4MPSU includes a 100-240 VAC, 50/60 Hz power supply delivering 13.8 VDC at 3.3 amps to support the controller and connected access control equipment. The panel provides a total of 3 amps at 12 VDC for compatible locking devices and peripherals, subject to individual output limitations and the overall system power budget. A supplied 12 VDC, 7 Ah backup battery supports continued operation during an interruption of primary AC power, with backup duration dependent on connected loads. The metal enclosure measures approximately 14.1 inches high, 16.1 inches wide, and 4.3 inches deep and incorporates removable terminal blocks, multiple wiring knockouts, panel tamper monitoring, and a removable enclosure door for installation and service access. The package includes four MPA2RJ RJ45-to-terminal adapters, four MPA2S5 suppressor/supervisory cables, and one MPA2BAT7 backup battery.

The MPA4MPSU supports Ethernet, RS-485, and USB-C communication, with Bluetooth Low Energy connectivity for initial configuration through the Honeywell Device Utility App. Its secondary Ethernet interface supports network cascading between compatible controllers, while supported RS-485 configurations allow expansion to 36 doors and 72 readers across a controller loop. Access management capabilities include card-only, PIN-only, card-and-PIN authentication, anti-passback, door lockdown, escort mode, configurable time zones, and event reporting. The controller supports a standalone database capacity of 100,000 cardholders and events, with additional management capabilities available through compatible hosted software. Listed to UL 294 for access control system units, the Honeywell MPA4MPSU is suitable for offices, educational facilities, healthcare buildings, warehouses, and multi-site commercial properties requiring scalable, network-connected access control with integrated power distribution and backup protection.
