Orbbec Astra Microphone Specs

I would like to know where I can find the specs for the microphones in the Astra. I would like to use these mics to detect fire alarms which have these characteristics:

Sound (audible signals)
~3 kHz / ~3100 Hz tone (high frequency). Used in many current notification devices.
520 Hz (low frequency). Used in newer notification devices.
45 dB to 120 dB A weighted for human hearing (higher decibels, in the 100 to 120 dB range, were common with older fire alarm horns)

Hi, Trosky,

Below is the general spec of the microphone of Astra. Hopefully this information is helpful.
