Paradox ACM12-E9R 4-Wire Access Control Module for Digiplex EVO

The Paradox ACM12-E9R (ACM12) is a single-door access control module designed for seamless integration with Paradox Digiplex EVO control panels (such as EVO192 and EVOHD+). Connected directly via the 4-wire combus layout, it allows the intrusion security system to double as a fully featured access control network, managing entry permissions, schedules, and door status without requiring a standalone access control headend.

Supporting 4-wire RS-485 readers (such as the Paradox R910 and R915 series) or standard 26-bit Wiegand reader interfaces, the ACM12 controls 1 door (card entry / card or button exit). It includes an on-board 5A Form C relay output for electric strikes or magnetic locks, a door contact input, a request-to-exit (REX) input, and a door position switch input. The module supports advanced features including door unlock schedules, door-left-open alarms, forced-door alarms, and anti-passback rules managed centrally via EVO panels or Paradox NEware software.
