12. Special Functions
◆ 12.1 Battery Test
The battery backup time test checks whether the batteries are able to operate the
existing load during a power outage. The test is performed without interrupting the load.
We recommend that batteries be tested once every three months. The test should be
performed after the batteries have been allowed to charge for at least 12 hours.
However, if the P.R.O. LED is off, the battery test cannot be performed.
