An injector air outlet includes a temperature sensor and a smoke sensor to simultaneously carry out the functions of air recirculation and temperature and smoke monitoring within a closed interior space, such as a passenger cabin or a freight or cargo hold in an aircraft. The injector air outlet includes a housing wall (2) with an injector mixing chamber (3) therein. A primary supply air inlet (4) receives primary supply air (5) from the aircraft's air distribution duct network, and blows the primary supply air through an injection nozzle (7) into the mixing chamber (3) so as to create a reduced or negative pressure in the mixing chamber. Cabin exhaust air (10) is sucked through a secondary air inlet (9) and a secondary air channel (8) into the mixing chamber (3), due to the reduced pressure or suction effect therein. The primary air and secondary air are mixed together and then ejected forcefully back into the cabin or cargo hold. A sensor unit (12) including a temperature sensor (12A) and a smoke sensor (12B) is installed in the secondary air channel (8) so that a flow of exhaust air (10) is continuously positively caused to flow over the sensor unit (12).
