When ambient temperature rises beyond the preset increase rate, the heat sensitive element held to the detector reacts to heat in a way of inflating air therein, causing the diaphragm to be pushed upwards and the electrical contact to activate to make signal lamp to light up and send fire signal to the receiver.
Prevention of non-fire alarm generation: Erroneous non-fire alarming is minimized by make air to be leaked to the leak hole in the case of low rate of rise in temperature.
