Yes my fish store tech just programmed my Apex to detect power outage and turn off hi draw devices so my battery UPS can last longer. I had to by a device that plugs into Apex CPU and wall out directlyFor those of you using an Apex and a UPS backup battery, be sure to follow the instructions in my tutorial on Apex Power Monitoring to allow the Apex to detect when the power is out. It can be programmed to automatically turn off high-powered devices like heaters, lights, and pumps to preserve the battery life for water movement. It can also send you an alarm notification about the power failure if your Internet router is also plugged into UPS battery power.
