Jim,
The TPN1106A is one of a few Motorola MICOR power supplies that are
designed to float-charge either NiCd or lead-acid batteries for
emergency backup. There is an internal pot to adjust the voltage for
the chemistry of the battery.
When the TPN1106A power supply is used, the battery is connected
directly to the same terminals that feed the PA. You cannot do this
with other power supplies, because the battery may discharge back
through the power supply during an outage, possibly damaging the power
supply.
The complete details of the TPN1106A power supply and the battery
protection and alarm system are contained in a 32-page manual
6881104E92, which is still available from Motorola Parts.
