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). See Figure 4.
4.
If you install the A4905-9838 Sound Damper, the anechoic measurements decrease by approximately 9 dBA.
