Maximal Fe Overview; Maximal Fe Features - Altronix Maximal FE Series Installation Manual

Maximal Expandable Power Systems provide system designers and installers with optimum power choices and
the highest levels of versatility. They provide 12VDC, 24VDC, or 12VDC and 24VDC simultaneously via two (2)
single output power supply/chargers. Includes AC fail, low battery, and battery presence monitoring. Enclosure
accommodates up to four (4) 12VDC/12AH batteries. All interconnecting equipment must be UL Listed.
Input:
• 120VAC, 60Hz.
Output:
• For output voltage and supply current, refer to
Maximal FE series Configuration Chart, pg. 5.
• Auxiliary Class 2 power-limited output rated @ 1A
(unswitched).
• Overvoltage protection.
Battery Backup:
• 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.
Fire Alarm Disconnect:
• Supervised Fire Alarm disconnect (latching or non-
latching) 10K EOL resistor. Operates on a normally
open (NO) or normally closed (NC) trigger.
Maximal11FE only: This unit is classified as Class 2 Power-Limited stand alone power supply with stand-by
battery and it is suitable to power sensors, electro-mechanical devices (e.g. electric door strikes) .
Maximal13FE has one Class 2 power-limited board (eFlow4NB) and one non power-limited (eFlow6NB).
*Maximal33FE, Maximal35FE, Maximal37FE, Maximal55FE, Maximal75FE, Maximal77FE: 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.
