Data Sheet

Maximal75D distributes and switches power to access control systems and ac-
cessories. Unit converts a 115VAC 60Hz input into sixteen (16) independently
controlled 12VDC and 24VDC Class 2 Rated PTC protected power-limited out-
puts. The outputs are activated by an open collector sink or normally open (NO)
dry trigger input from an Access Control System, Keypad, Push Button, REX
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 sixteen (16) outputs. All interconnecting equipment must be UL Listed.
