BATTipx unit for AC Powered Systems
This section describes how to operate and test the BATTipx backup battery pack unit
(supplied by the manufacturer) on systems that use AC power. This test ensures that
the BATTipx battery pack will provide power in the event of a power failure.
To check the internal batteries, BATTipx, operation (after installation of the PS500 AC
power supply and initialization of the system), disconnect the power connection from
the PS500 unit, make some calls, and verify that the Coral IPx 500 system still operates.
This operation should be done with fully charged batteries, or batteries that have been
charged for 24 hours. The battery voltage with no load should be a minimum of
48VDC. This should be checked with a DVM.
The batteries in the battery pack are fully charged when they leave the factory.
However, they discharge slowly when kept in storage. If a battery is defective, the
entire battery pack should be replaced as
described on

Batteries
