First Claim
1. A hazard detection system, comprising:
- a housing;
a safety processor;
system processor;
a plurality of sensors;
an alarm coupled to the safety processor;
a speaker coupled to the system processor, wherein the safety processor, the system processor, the plurality of sensors, the alarm, and the speaker are included with the housing; and
a plurality of multi-criteria state machines for managing a plurality of states based on data acquired by at least one of the sensors and based on at least one condition parameter, wherein the plurality of states comprises at least one alarming state and at least one pre-alarming state, wherein the at least one alarming state controls use of the alarm, and wherein the at least one pre-alarming state controls use of the speaker playing back a message, wherein the plurality of multi-criteria state machines comprises;
at least one sensor state machine that manages the at least one alarming state and that is implemented on the safety processor; and
at least one sensor state machine that manages the at least on pre-alarming state and that is implemented on the system processor.

Abstract
Systems and methods for using multi-criteria state machines to manage alarming states and pre-alarming states of a hazard detection system are described herein. The multi-criteria state machines can include one or more sensor state machines that can control the alarming states and one or more system state machines that can control the pre-alarming states. Each state machine can transition among any one of its states based on sensor data values, hush events, and transition conditions. The transition conditions can define how a state machine transitions from one state to another. The hazard detection system can use a dual processor arrangement to execute the multi-criteria state machines according to various embodiments. The dual processor arrangement can enable the hazard detection system to manage the alarming and pre-alarming states in a manner that promotes minimal power usage while simultaneously promoting reliability in hazard detection and alarming functionality.
