Honeywell Commercial Security MPA4MPXPSU Access Control Panel

Product Description

The Honeywell Commercial Security MPA4MPXPSU is a multi-door access control panel that integrates an enclosure, power supply, and battery backup to support up to four proximity readers. This unit is designed for commercial security applications where centralized door access management is required. It provides the core hardware infrastructure for credential-based entry control, combining power distribution and reader connectivity in a single enclosure. Licensed security integrators and commercial electricians typically source this panel for new installations and system expansions where multi-reader support is needed in a consolidated form factor.

The MPA4MPXPSU is intended for commercial building access control deployments. It suits environments requiring control of multiple entry points from a single panel location, such as office buildings, warehouses, and institutional facilities. The multiple-door category designation indicates this unit is built to manage concurrent reader inputs and access decisions across up to four doors simultaneously. It is typically installed in a secured electrical room or telecom closet as part of a broader security management system.

Follow applicable NEC low-voltage wiring requirements and the facility's access control system documentation when connecting reader inputs and door hardware. Verify battery connections and polarity before restoring power to the enclosure.
