RMS current ratings are per UL maximum RMS method. UL max current rating is the maximum RMS current within the listed voltage range (16-33v for 24v units). For strobes the
UL max current is usually at the minimum listed voltage (16v for 24v units). For audibles the max current is usually at the maximum listed voltage (33v for 24v units). For unfiltered
FWR ratings, see installation instructions.
b dBA ratings are based on testing under UL Standard 1480.
c 1/8 watt tap is for private mode only.
