ACM4 Series
Overview:
These units convert one (1) 12 to 24 volt AC or DC input into four (4) independently controlled fused or PTC
protected outputs. These power outputs can be converted to dry form “C” contacts (ACM4 only). 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. The units will route power to a variety of access control hard-
ware devices including Mag Locks, Electric Strikes, Magnetic Door Holders, etc. All interconnecting devices
must be UL Listed. 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.
