Abstract
A master slave architecture includes a common power supply on a common distribution bus that is used by the master to provide a separate alarm power bus to all of the slaves for powering their individual alarm monitoring circuits for providing the capability to detect an open circuit or loss of power to the slave, and to eliminate hot signals which might otherwise result in CMOS latchup in the slaves; individual slaves having alarm conditions may be individually identified by using an alarm inventory bus.
