- 3 - Maximal11FD/Maximal33FD/Maximal55FD/Maximal77FD/Maximal75FD Access Power Controllers (PTC)
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 provides common power for ACM8CB board (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.
• Maximum charge current 1.54 amp.
• Automatic switch over to stand-by battery when AC fails. Transfer to stand-by battery power is instantaneous with no interruption.
• Supervised Fire Alarm disconnect (latching or non-latching) 10K EOL resistor. Operates on a normally open (NO) or
normally closed (NC) trigger.
• AC fail supervision (form “C” contacts).
• Battery fail and presence supervision (form “C” contacts).
• Low power shutdown. Shuts down DC output terminals if battery voltage drops below 71-73% for 12V units and 70-75%
for 24V units (depending on the power supply). Prevents deep battery discharge.
• For PTC ratings refer to MaximalFD series Configuration Chart, pg. 2.
• Green AC Power LED indicates 120VAC present.
• AC input and DC output LED indicators.
• Short circuit and overload protection.
• Enclosure accommodates up to four (4) 12VDC/12AH batteries.
Enclosure dimensions (H x W x D): 26” x 19” x 6.25” (660.4mm x 482.6mm x 158.75mm).
MaximalFD Installation Instructions:
Wiring methods shall be in accordance with the National Electrical Code/NFPA 70/ANSI, the Canadian Electric Code, Part I, Part II
and with all local codes and authorities having jurisdiction. Product is intended for indoor use only.

1. Mount unit in desired location. Mark and predrill holes in the wall to line up with the top three keyholes in the enclosure. Install
three upper fasteners and screws in the wall with the screw heads protruding. Place the enclosure’s upper keyholes over the three
upper screws; level and secure. Mark the position of the lower three holes.
Remove the enclosure. Drill the lower holes and install the three fasteners. Place the enclosure’s upper keyholes over the three
upper screws. Install the three lower screws and make sure to tighten all screws (Enclosure Dimensions, pg. 12).
2. Connect unswitched AC power (120VAC 60Hz) to terminals marked [L, N] (Fig. 3, pg. 8). Use 14 AWG or
larger for all power connections. Secure green wire lead to earth ground.
Keep power-limited wiring separate from non power-limited wiring. Minimum 0.25” spacing must be provided (Fig. 3, pg. 8).
CAUTION: Do not touch exposed metal parts. Shut branch circuit power before installing or servicing equipment.
There are no user serviceable parts inside. Refer installation and servicing to qualified service personnel.
