6. Other Functions
1. If the opaque material is taken out from the detector in less than 15
seconds, then the detector automatically reset to normal status.
2. If the opaque material is not taken out from the detector and is
maintained for more than 15 seconds then a fire signal is registered,
turn-off the power for at least 2 seconds to reset the detector.

6. Other Functions
automatic Compensation of light
When dust exists in the working environment of the detector, the emitting window,
receiving window and reflector will be covered with dust, which will affect normal
operation. In order to solve the problem, we designed the function of automatic
compensation of light. When there is dust on windows, the detector can judge the
amount of dust, and compensate the received signal through internal program and
circuit to ensure the detector can continue to work normally. The detector gives fault
signal when dust on the lens and reflector surface reaches a certain level and light
compensation reaches the limit for the detector to work normally.
self-diagnosis on optical signal
The detector has functions of checking emitting, receiving and amplifying circuit.
When there is fault with these three parts of circuit during operation, the detector
will generate fault information.
