Model BA-197WN PRO-TEC™ Heavy-Duty White Noise Back-Up Alarm 12-24 Volt 97 Decibel

Every day employers are replacing the old fashion beepbeep  backup alarm on industrial equipment and vehicles  with new back-up alarms that produce a totally different sound known as WHITE NOISE, a pulsing “pssspsss” sound. People get used to hearing conventional  beeping backup alarms and ignore them, while people who hear the broadband WHITE NOISE “psss-psss” sound are less likely to ignore the warning that a vehicle  is backing-up. Designed with the same features as Wolo’s Model BA-197WN, the electronics is sealed in rock  hard epoxy to withstand all weather conditions. Easily  installs to any one or two wire system, and automatically adjusts to a voltage range of 12-24-volt DC.
