Backup Alarm - Single Sound
Mack

This audible device is purpose built to alert nearby personnel and vehicles during vehicle backing. The single tone configuration is easily heard in noisy yards or urban environments, providing a clear warning that helps prevent collisions during maneuvering. Installations typically connect to standard power circuits and mount to trucks with minimal modification, making it a straightforward upgrade for safety compliance. The unit is designed to resist vibration and weather exposure, a common requirement for exterior mounting on medium and heavy duty rigs. Beyond compliance, the alarm supports fleet productivity by reducing incident-related repair costs and downtime resulting from backing accidents. Its compact profile allows placement at the dash or bumper without obstructing other controls. Regular inspection ensures horn integrity and battery condition for continuous operation.
