1. A wireless flame detector comprising:
a battery;
at least one optical sensor having an electrical characteristic that varies with incident radiation within a wavelength band of flame;
measurement circuitry coupled to the at least one optical sensor and the battery, the measurement circuitry being configured to provide an indication relative to the electrical characteristic of the at least one optical sensor;
a controller coupled to the measurement circuitry and battery, the controller being configured to receive the indication, the controller being configured to operate in a low-power mode during which the electrical characteristic of the at least one optical sensor is continuously monitored, and a second mode that provides full flame anti-false alarm processing, wherein the controller is configured to enter the second mode upon detection of an event while operating in the first mode; and
wireless communication circuitry operable coupled to the battery and the controller and configured to selectively communicate wirelessly with at least one remote device based on the full flame anti-false alarm processing.
