The LR5-BU buzzer unit sits at the top of any of the LR5 signal light towers from Patlite. The sound output pressure is typically 85 dB at 1 metre and covers a full 360º around the signal light unit. Sealed waterproof to IP65, the sound patterns have been specifically developed to ensure the alarm output is heard over the background noise of industry.
The buzzer sound options are controlled by internal DIP switches as listed below:
- No 1 - Rapid Intermittent Beep.
- No 2 - Continuous Beep.
- No 3 - Rapid Hi-Low.
- No 4 - Sweep Sound.
In addition to providing the alarm sound, the buzzer unit provides the signal light towers with the flashing light option at 60 flashes per minute.
