DC outputs for these power supplies are not power-limited. If a power-limited output is required in the end-product ap­plication, 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-productapplication 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.

MaxFitFE Series Features:

• 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).

Wiring methods shall be in accordance with the National Electrical Code/NFPA 70/NFPA 72/ANSI,

MaxFitFE Installation Instructions:

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. 4). 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, (MaxFit3FE) (Fig. 2a, pg. 4).
MaxFit5FE power supply is factory set at 12VDC.

MaxFit7FE power supply is 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. 4). 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. 4). Refer to page 2 for non power-limited applications.

6. For Access Control applications batteries are optional. When batteries are not used, a loss of AC will result
in the loss of output voltage. When the use of stand-by batteries is desired, they must be lead acid or gel type.
Connect battery to the terminals marked [– BAT + ] (Fig. 1g, pg. 4). Use two (2) 12VDC batteries connected
in series for 24VDC operation (battery leads included). Use batteries - Casil CL1270 (12V/7AH), CL12120
(12V/12AH), CL12400 (12V/40AH), CL12650 (12V/65AH) batteries or UL recognized BAZR2 batteries of
an appropriate rating.

7. Connect appropriate signaling notification devices to AC FAIL & BAT FAIL (Fig. 1b, pg. 4) supervisory
relay outputs.

8. To delay AC reporting for 2 hrs., set DIP switch [AC Delay] to OFF position (Fig. 1c, pg. 4).
To delay AC reporting for 1 min., set DIP switch [AC Delay] to ON position (Fig. 1c, pg. 4).
Note: Must be set to ON position for Burglar Alarm Applications.

9. To enable Fire Alarm Disconnect set DIP switch [Shutdown] to ON position. (Fig. 1c, pg. 4).
To disable Fire Alarm Disconnect set DIP switch [Shutdown] to OFF position. (Fig. 1c, pg. 4).

10. Trigger terminals are end of a line resistor supervised (10k Ohms). Opening or shorting trigger terminals
will cause [DC] output to shutdown (Fig. 1d, pg. 4).

11. Place a jumper for non-latching FACP. A momentary short on these terminals resets FACP latching
[Trigger EOL Shutdown] (Fig. 1d, pg. 4).

12. For Access Control Applications: mount UL Listed tamper switch (Altronix Model TS112 or equivalent) at
the top of the enclosure. Slide tamper switch bracket onto the edge or the enclosure approx. 2” from the
right side (Fig. 3a, pg. 6). Connect tamper switch wiring to the Access Control Panel input or the appropriate
UL Listed reporting device.

13. Please ensure that the cover is secured with the provided key lock.

Use 18 AWG or larger for all low voltage power connections.
Note: Take care to keep power-limited circuits separate from non power-limited wiring (120VAC, Battery).

Maintenance:

Unit should be tested at least once a year for the proper operation as follows:
Output Voltage Test: Under normal load conditions the DC output voltage should be checked for proper
voltage level (MaxFitFE Configuration Chart, pg. 2).
Battery Test: Under normal load conditions check that the battery is fully charged, check specified
voltage at the battery terminals and at the board terminals marked [– BAT +] to
ensure that there is no break in the battery connection wires.
Note: Maximum charge current 1.54A.
Expected battery life is 5 years; however, it is recommended to change batteries within 4 years or less if necessary.

NEC Power-Limited Wiring Requirements:

circuit wiring must remain at least 0.25” away from any non power-limited circuit wiring. Furthermore, all
power-limited circuit wiring and non power-limited circuit wiring must enter and exit the cabinet through differ­ent conduits. One such example of this is shown below. Your specific application may require different conduit
knockouts to be used. Any conduit knockouts may be used. For power-limited applications use of conduit is
optional. All field wiring connections must be made employing suitable gauge
CM or FPL jacketed wire (or equivalent substitute). Optional UL Listed
battery enclosure must be mounted adjacent to the power supply via Class 1
wiring methods. For Canadian installations use shielded wiring for all connections.
Note: Refer to wire handling drawing below for the proper way to install the
CM or FPL jacketed wire (Fig. 3b).
