The ADT 700 is an unique tool for installing and testing the function of the AD 700 and AD 800 detectors series. It sends out a frequency spectrum; a number of signals with specific frequencies and amplitude. The acoustic signals in the room with the AD 700 detector are recorded by the AD 700 tester with a wide band microphone. The signals are filtered before being processed and evaluated. The microprocessor compensates for early reflections and selects the best algorithms for the position of the detector to ensure maximum detection capacity. The signal undergoes dramatic changes during its journey from the broken glass to the detector. Due to these reflections and the attenuation, the signal looks different depending on distance. The AD 700 therefore has 3 separate ranges and in each range the decision algorithm is different. With the ADT 700 tester it is possible to conduct accurate testing of the range setting. The detector measures the characteristic signal and its processor recommends which setting is optimal for the selected installation.
