In outdoor or wet installations, bell must be mounted with
weatherproof backbox, BBK-1 or BBX-1. Standard electrical boxes
will not provide a weatherproof enclosure. If the bell and/or assembly
is exposed to moisture, it may fail or create an electrical hazard.
Notes:
1. Minimum dB ratings are calculated from integrated sound pressure
measurements made at Underwriters Laboratories as specified in UL
Standard 464. UL temperature range is -30° to 150°F (-34° to 66°C).
2. Typical dB ratings are calculated from measurements made with a
conventional sound level meter and are indicative of output levels in
an actual installation.
3. ULC only applies to MBA DC bells.
