Maximal3FV / Maximal5FV / Maximal7FV Access Power Controllers (Fused)
eFlow Power Supply/Charger:
• Input: 220VAC (working range 198VAC - 256VAC), 50/60Hz.
• For output voltage and supply current refer to MaximalFV series Configuration Chart, pg. 3.
• Auxiliary output rated @ 1A (unswitched).
• Overvoltage Protection.
• Built-in charger for sealed lead acid or gel type batteries.
• Maximum charge current 1.54A.
• 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 fuse ratings refer to MaximalFV Series Configuration Chart, pg. 3.
• Green AC Power LED indicates 220VAC 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 158.8mm).
MaximalFV 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 (220VAC 50/60Hz) to terminals marked [L, N] (Fig. 3, pg. 9). Do not use
terminal marked [G]. Use 14 AWG or larger for all power connections. Secure ground wire lead to
earth ground lug.
Keep power-limited wiring separate from non power-limited wiring.
Minimum 0.25” spacing must be provided.
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.
3. Select desired DC output voltage by setting SW1 to the appropriate position on the Maximal3FV power
supply
(Fig. 1a, pg. 7). Maximal5FV power supply is factory set at 12VDC and Maximal7FV power supply
is factory set at 24VDC.
4. Measure the output voltage of the unit before connecting any devices to ensure proper operation.
Improper or high voltage will damage these devices.
5.
Output options (Fig. 2, pg. 8):
The unit will provide either sixteen (16) switched power outputs, sixteen (16) dry form “C” outputs, or any
combination of both switched power and form “C” outputs.
(a) Fail-Safe Switched Power outputs:
For Fail-Safe operation connect the positive (+) input of the access control devices to terminal marked
[NC]. Connect the negative (–) input of the access control devices to terminal marked [COM].
(b) Fail-Secure Switched Power outputs:
For Fail-Secure operation connect the positive (+) input of the access control devices to terminal marked
[NO]. Connect the negative (–) input of the access control devices to terminal marked [COM].
(c) Form “C” outputs:
When form “C” outputs are desired, the corresponding output fuses (1-8) of each ACM8 board must
be removed.
