A system which allows the firefighter to monitor a variety of safety related parameters during firefighting activities through audible and/or visual means. The system of the present invention monitors the pressure in the firefighter's breathing system and also monitors ambient temperature and motion of the firefighter. An audible alarm is activated to indicate a potential emergency situation relating to low remaining air time, impending thermal breakthrough or lack of motion of the firefighter.

[ We claim:] [1.]1. A method of providing electrical power to a microprocessor within a monitoring and alarm system used with self contained breathing apparatus, the method comprisingcoupling a pressure transducer to the breathing apparatus and the microprocessor;supplying a continuous portion of electrical power to the microprocessor to monitor a signal indicative of transduced breathing apparatus pressure; andallowing an activating portion of electrical power to flow to the microprocessor for monitoring at least one signal in addition to said pressure signal when transduced breathing apparatus pressure exceeds a predetermined value.
