- 2 - Maximal3FD/Maximal5FD/Maximal7FD Access Power Controllers (PTC)
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 protected outputs. 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. 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.

MaximalFD Series Features:
ACM8CB Access Power Controller Modules:
• Sixteen (16) independently trigger controlled outputs. Output options:
a) Sixteen (16) Fail-Safe filtered power outputs.
b) Sixteen (16) Fail-Secure filtered power outputs.
c) Any combination of the above.
• Sixteen (16) Access Control System trigger inputs. Input trigger options:
a) Sixteen (16) normally open (NO) dry trigger inputs.
b) Sixteen (16) open collector inputs.
c) Any combination of the above.
• Sixteen (16) unswitched filtered aux. power outputs (outputs are rated @ 2 amp).
• Red LEDs on ACM8CB board indicate individual outputs are triggered (relays energized).
• Fire Alarm disconnect (latching or non-latching) is individually selectable for any or all of the sixteen (16) outputs.
Fire Alarm disconnect input trigger options:
a) Normally open (NO) or normally closed (NC) dry trigger input.
b) Polarity reversal input from FACP signaling circuit.
• Green LED on ACM8CB board indicates FACP disconnect is triggered.
• FACP output relay indicates that FACP input is triggered (form “C” contact rated @ 1 amp/28VDC not evaluated by UL).
• eFlow Power Supply/Charger board provides common power for both ACM8CB Access Power Controller boards
(factory wiring) and all connected access control devices (field wiring).
• ACM8CB board main fuses are rated @ 10 amp. Output PTCs are rated @ 2.0 amp.
eFlow Power Supply/Charger:
• Input: 120VAC, 60Hz.
• For output voltage and supply current refer to MaximalFD series Configuration Chart, pg. 2.
• Auxiliary Power-Limited output rated @ 1 amp (unswitched).
• Overvoltage protection.
• Built-in charger for sealed lead acid or gel type batteries.
