ABSTRACT:
An intelligent switching mechanism for the backup batteries of an alarm system is disclosed. When AC input power has failed but no alarm has been declared, the batteries are switched into a parallel configuration, which is sufficient to supply the control panel, so that the batteries are drained in tandem. When AC input power has failed and an alarm has been declared, the batteries are switched into a series configuration to supply power at the higher voltage required by the alarm annunciators.
