7.5 Heat Detector

The detector measures the onsite temperature in real time. When the detector
works in monitoring mode, the red indicator blinks and the operating current is
low. When the onsite temperature exceeds the alarm threshold, the detector
enters alarm mode, the red indicator is steady on, and the circuit current increases
rapidly. The detector issues an alarm signal in the form of circuit current change,
and provides the alarm locking function. The alarm can be reset only by short-
time power-off.
