- 2 - Maximal3F/Maximal5F/Maximal7F Access Power Controllers (Fused)
MaximalF Series Overview:
MaximalF 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 fuse protected outputs. These Fail-Safe/Fail-Secure power
outputs may be converted to dry form “C” contacts. 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.

The DC output for these power supplies are not power-limited. If a power-limited output is required in the end-product application, the
DC output from the power supply must be connected to a separately Listed control unit or accessory board that provides power-limited
outputs. The product(s) providing the power-limited output(s) must be listed as appropriate for the particular end-product application
(access control), and wired in accordance with the products installation instructions. Class 1 wiring methods, separation of circuits, and
proper fire-rated enclosures all must be considered when connecting the DC output of the power supply to the end-product devices. The
auxiliary outputs of these units are power-limited.

MaximalF Series Features:
ACM8 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) Sixteen (16) form “C” relay outputs (rated @ 5 amp/28VDC or VAC).
d) 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 @ 2.5 amp).
• Red LEDs on ACM8 board indicate individual outputs are triggered (relays energized).
• Fire Alarm disconnect (latching or non-latching) is individually selectable for any or all of the eight (8) 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 ACM8 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 ACM8 access power controller boards (factory wiring)
and all connected access control devices (field wiring).
• ACM8 board main fuses are rated @ 10 amp. Output fuses are rated @ 2.5 amp.
