Technology partner: V474 Altronix Corporation
Altronix ACM4E converts one (1) 12 to 24 VAC or VDC input into four (4) independently controlled fuse protected outputs. These power outputs can be converted to dry form C contacts. Outputs are activated by an open collector sink or normally open (NO) dry trigger input from an Access Control System, Card Reader, Keypad, Push Button, PIR, etc. ACM4E will route power to a variety of access control hardware devices including Mag Locks, Electric Strikes, Magnetic Door Holders, etc. Outputs will operate in both Fail-Safe and/or Fail-Secure modes. Units are designed to be powered by one common power source which will provide power for both the board operation and locking devices, or two (2) totally independent power sources, one (1) providing power for board operation and the other for lock / accessory power. The FACP Interface enables Emergency Egress, Alarm Monitoring, or may be used to trigger other auxiliary devices. The fire alarm disconnect feature is individually selectable for any or all of the four (4) outputs.


  • 12 to 24 volt AC or DC operation (setting not required).
  • Any combination of the above.
  • Any power output may be converted to dry form ''C'' relay output.
  • Fire Alarm Disconnect (latching or non-latching) is individually selectable for any or all of the four (4) outputs.
  • Fire Alarm Disconnect:
  • Fire Alarm output relay for triggering auxiliary reporting devices
  • Fire Alarm trigger LED indicates that the Fire Alarm Disconnect has been activated.
  • Four (4) Access Control System outputs.
  • Four (4) Access Control System trigger inputs.
  • Four (4) fuse protected 12VDC auxiliary power outputs (unswitched).
  • Four (4) fuse protected Fail-Safe and/or Fail-Secure 12VDC power outputs.
  • Four (4) normally open (NO) inputs.
  • Four (4) open collector inputs.
  • Normally open (NO) or normally closed (NC) dry contact input.
  • One (1) common power input (board and lock power).
  • one (1) for lock/hardware power).
  • Polarity reversal input FACP signaling circuit.
  • Power Supply Input Options:
  • Red LEDs indicate outputs are triggered (relays energized).
  • Two (2) isolated power inputs (one (1) for board power and
