Description
These vibrating type bells are designed for use as fire or general
signaling devices. They have low power consumption and high decibel
ratings. The unit mounts on a standard 4” (101mm) square electrical
box for indoor use or on a model BBK-1 or HC-BB weatherproof
backbox for outdoor applications. Weatherproof backbox model BBK-
1 or HC-BB, Stock No. 1500001.
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.
