Single-pulse operation mode means: As long as the detector receives a pulse trigger signal (rapidly changing energy environment will be an infrared sensor to sensor and outputs a pulse signal in the internal circuits) to the police. In this mode of operation, high sensitivity of the detector can be used in a good environment and relatively enclosed indoor area.

Double-pulse mode means: when the detector only receives more than twice the pulse signal alarm. The majority of cases, cause false triggering of the signal detector by only one pulse fluctuations, therefore, the use of double-pulse mode can effectively reduce the probability of false alarm. In a harsh environment, or a relatively open area, the proposed dual-pulse mode.
