MPA2C3 Installation Guide 153
Battery Supply
The MPA2C3 Enclosure panel provides room for 12 VDC, 7Ah / 12 VDC, 12Ah
sealed lead acid battery. If PSU and battery are both connected, the panel will use
PSU as primary power and a battery as a secondary power. MPA2C3 power man-
agement circuit will manage the battery charging. When PSU goes down, the panel
will continue to work on Battery. When the battery goes down, the panel shuts
down.
• In that case, you can connect the cable to Ethernet 1 RJ45 port to reboot the
system through PoE+.
• The battery recommended by Honeywell is 12 VDC,7 Ah (MPN:MPA2BAT7). The
other battery purchased by customer should meet the local regulations.
