*MaxFit13FE, MaxFit33FE, MaxFit35FE, MaxFit37FE, MaxFit55FE, MaxFit75FE and MaxFit77FE:
The DC output for these power supplies are not power-limited (except for eFlow4NBs in MaxFit13FE). 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 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.
• Input: 120VAC, 60Hz.
• For output voltage and supply current refer to MaxFitFE series Configuration Chart, pg. 2.
• Auxiliary Power-Limited 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 & 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 MaxFitFE 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): 20.5” x 16.5” x 6.25” (520.7mm x 419.1mm x 158.8mm).
MaxFitFE Installation Instructions:
Wiring methods shall be in accordance with the National Electrical Code/NFPA 70/NFPA 72/ANSI, The Canadian Electrical Code, Part 1 and with all local codes and authorities having jurisdiction. The product must be
located indoors within the protected premises.
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. 8).
2. Connect unswitched AC power (120VAC 60Hz) to terminals marked [L, N] (Fig. 1a, pg. 5). Use 14 AWG
or larger for all power connections. Secure green wire lead to earth ground.
For Fire Alarm applications the outputs are “Special Applications” only.
Keep power-limited wiring separate from non power-limited wiring (120VAC 60Hz Input, Battery Wires).
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 (MaxFit11FE, MaxFit13FE,
MaxFit33FE, MaxFit35FE and MaxFit37FE) (Fig. 2a, pg. 5).
MaxFit55FE power supplies are factory set at 12VDC.
MaxFit77FE power supplies are factory set at 24VDC (Stand-by Battery Specifications, pg. 5).
4. Measure output voltage before connecting devices. This helps avoiding potential damage.
5. Connect devices or Altronix sub-assembly modules to be powered to the terminals marked [– DC +]
(Fig. 1h, pg. 5). For auxiliary device connection, this output will not be affected by
Low Power Disconnect or Fire Alarm Interface. Connect device to the terminals
marked [+ AUX –] (Fig. 1f, pg. 5). Refer to page 2 for non power-limited applications.
