SoundOff Backup Alarm

SoundOff Backup Alarm

Ensure OSHA compliance and protect ground personnel with the rugged SoundOff Signal ETBUALM03 Backup Alarm. Commercial utility trucks, DOT snowplows, and heavy construction equipment suffer from massive blind spots, making reversing a highly dangerous maneuver. This severe-duty alarm mitigates that risk by blasting a piercing 102 dB(A) warning tone every time the vehicle engages reverse. Built with an epoxy-encapsulated circuit board and a heavy-duty, glass-filled nylon housing, it is entirely impervious to high-pressure washing, extreme engine vibration, and the harshest winter road salt.

Key Features & Upfitter Specs

• 102 dB Warning Power: Blasts an incredibly loud, SAE J994 Type F compliant warning tone that immediately alerts pedestrians and ground workers over the roar of diesel engines and heavy machinery.
• Severe Duty Construction: The housing is molded from ultra-rugged, glass-filled nylon, while the internal electronics are completely potted in epoxy to eliminate vibration damage and moisture ingress.
• IP67 Waterproof: Carries a strict IP67 environmental rating, allowing it to be safely mounted underneath the chassis or behind the rear axle where it will be subjected to intense water spray.
• Voltage Protection: Engineered to accept a wide 12-24 Vdc input range, featuring advanced internal circuitry that protects the alarm against devastating voltage spikes and reverse polarity.
• Universal Fleet Mounting: The compact 4-inch by 3-inch footprint and standard universal mounting bracket make it incredibly easy to retrofit onto any commercial chassis or utility bed.
