Claim:
1. A hazard detection system, comprising: a DC power source; a power bus coupled to the DC power source; a first group of components that are operable to be power gated ON and OFF, wherein the first group of components comprises a first hazard sensor; power gating circuitry that selectively couples and de-couples the first group of components to the power bus; a second group of components that are not operable to be power gated ON and OFF, the second group of components coupled to the power bus, wherein the second group of components comprises a second hazard sensor; and control circuitry operative to control the power gating circuitry by instructing the power gating circuitry to selectively couple and de-couple at least one component of the first group of components to the power bus.
