Note:
1. The coded category covers 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 (CFIG1) on the controller.
4. If you install the A4905-9838 Sound Damper, the anechoic measurements decrease by approximately 9 dBA.
