Grote 73240 Self-Adjusting Backup Alarm – 87dB to 107dB, Reverse Mounted Speaker, 12V/24V

Intelligent Audible Warning for Dynamic Work Zones The Grote 73240 Self-Adjusting Backup Alarm is a high-performance safety solution designed for environments with fluctuating noise levels. Unlike fixed-decibel alarms, the 73240 features "Smart" technology that constantly monitors ambient noise and automatically adjusts its output between 87dB and 107dB. This ensures the warning is loud enough to be heard in busy zones while reducing noise pollution in quieter areas.

Superior Sound Protection with Reverse Mounted Speaker Equipped with a reverse-mounted speaker, this alarm is engineered for maximum durability. By positioning the speaker away from the elements, Grote has created a unit that is highly resistant to dust, moisture, and high-pressure washing. The housing is constructed from heavy-duty glass-filled nylon, ensuring it can withstand the extreme vibrations and impacts common in construction and fleet operations.

Built for the Long Haul Designed for universal compatibility, the 73240 operates on both 12V and 24V DC systems, making it an ideal choice for everything from delivery vans to heavy-duty earthmovers. The internal electronics are fully sealed to operate in extreme temperatures, from -40°F to +185°F, providing consistent reliability regardless of the climate.
