Battery test fault voltage
During the automatic scheduled battery test the dc voltage will try to drop to 235 Vdc (11.75 x
20 batteries per poll). If the batteries are unable to hold the minimum charge the battery test will
fail due to one of the batteries having a lower voltage than 11.75 V dc.

Battery test failure will trigger a system alarm indicating requirement for battery
maintenance.
