Notes:
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 4905-9838 Sound Damper, the anechoic measurements
decrease by approximately 9 dBA.
