VULCANS
Low frequency: 650-750 Hz
High frequency: 900-1000 Hz
Operation mode: High/Low
The frequency is checked using anacom and the sound sensor sensor will only detect when it is at the high frequency level.

(this is not the exact datasheet as we cannot found the real one)
Low frequency (LF) 650Hz-750Hz to High frequency (HF) 1450Hz-1550Hz
Operation mode: Continuos
The frequency is checked using anacom and the sound sensor sensor will detect when it is at 750-1550 Hz. Due to its continuous mode, the detection of frequency is quicker than ambulance.
