Abstract (en)

[origin: EP0940789A2] The fire alarm method involves transmission of ultrasound signals from one transmitter and microwave- or optical- signals, or a combination of all three different wave-types from an additional transmitter. Doppler signals reflected from objects are received by receivers assigned to the transmitters, and the received signals are evaluated separately and in combination, so that a varied reception signal is detected for one type of wave, in the case that a reception signal for one or more other types of wave shows no movement, smoke, particles or variation in the gas composition in the detection zone.
