Maximal11FD/Maximal33FD/Maximal55FD/Maximal77FD/Maximal75FD Access Power Controllers (PTC) - 2 -
MaximalFD Series Overview:
MaximalFD Access Power/Controllers distribute and switch power to access control systems and accessories. They convert a 120VAC
60Hz input into sixteen (16) independently controlled 12VDC or 24VDC PTC protected outputs. Outputs are activated by an open col-
lector sink or normally open (NO) 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 eight
(8) outputs.
