Notes:
1. The coded category includes both Temporal and March Time cadences.
2. Reverberant dBA measurements are a minimum UL rating based on sound power level measurements made in UL’s reverberant test chamber.
3. High and low volume settings are configured with DIP Switch SW4 on the TrueAlert Addressable Controller.
