New Siemens ACEND Series Fire Alarm Horn Sound from Tablet By Myself Fire Drill!

In this video, I do a by myself Fire Drill With a new Fire Alarm Sound called the Siemens ACEND Series of fire alarm horns where the sound it makes is similar to an EST Genesis fire alarm horn sound but different as it's main frequency is 3,300 Hz with a 50 Hz modulation rate (with overtones) that's similar to the Genesis except it's 3,200 Hz without overtones as the newer Siemens ACEND makes a slightly higher pitch with the same modulation. The older Siemens Fire Alarms found in the UMMT features a 3,000 Hz sound with a 90 Hz modulation rate and it's similar in frequencies to the Simplex Truealert that's 3,000 Hz but it's modulation is different as it's 130 Hz so the Siemens UMMT sounds perceivably low pitched.
