Maximal Rack Access Power Controllers (PTC) - 3 -
Overview:
Maximal Rack Mount Series units distribute and switch power to access control systems and accessories. They convert a
115VAC 50/60Hz input into eight (8) or sixteen (16) independently controlled 12VDC and/or 24VDC PTC protected out-
puts. Outputs are activated by an normally open (NO) or normally closed (NC) dry trigger input from an Access Control
System, Card Reader, Keypad, Push Button, PIR, etc. Units 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. 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 outputs (see chart below).
