A flame detector for an aircraft includes a housing and two sensors positioned in the housing to detect light signals indicative of a flame event. The two sensors include a first sensor configured to detect light signals in at a first infrared wavelength range, and a second sensor configured to detect light signals at a second wavelength range. A controller is configured to receive signals from the two sensors, and to determine the presence of the flame event only if the signals indicative of the flame event are received from both of the two sensors. A method of detecting a flame event includes providing two sensors in a detector housing. A detection area is observed via the sensors, and detection signals received from the sensors are evaluated at a controller. The presence of a flame event is determined only if detection signals are received from both of the two sensors.

Dual band infra red optical fire detector

A multi-condition sensor, comprising a housing defining a component cavity, a pressure input tube disposed through the housing, a fault actuator disposed within the component cavity of the housing and in pressure communication with the pressure input tube through the housing, wherein the fault actuator is configured to extend and contract as a function of pressure from the pressure input tube, an alarm actuator disposed within the component cavity of the housing opposite the fault actuator and configured to be actuated by the fault actuator and to extend to a maximum fault position, and an adjustable alarm contact disposed on an opposite side of the alarm actuator within the component cavity and configured to be adjusted to a predetermined extension length from the housing to provide a predetermined alarm contact position.
