Answer: For SWIFI-MPRSB and SWIFI-MPRST - Up to 110dB;
For SWIFI-ACTIVEG2A, SWIFI-ACTIVEG2B - Up to 120dB.
Note: The decibel (dB) level of an alarm is a measure of its sound intensity, and it can vary due to several factors. The rating above is the maximum when measured in a controlled environment.
Readings depend on:
- Instrument used (phone app VS professional sound level meter)
- Distance from the source (sound intensity decreases with distance).
- Environment (open space vs enclosed room).
- Frequency weighting (usually A-weighted, denoted as dBA, to reflect human hearing sensitivity).
