External Power Supply
The MPA1C1 can also be powered from an external 12VDC
power supply.
If an external power supply is connected and powering, the
MPA1C1 will take power from the external power supply.
An external power supply is recommended in case of controlling
heavy duty locks (such as Magnetic locks), where output current
for the lock would exceed 500mA.
Backup power
The MPA1C1 can be powered from PoE or an external power supply. The
backup power supply must be connected to the power source.
Recommended backup power source

The 7Ah lead-acid battery in the external power supply is not
evaluated by UL294 and CAN/ULC60839-11-1
