Truck-Lite 92927 Dual-Function Self-Adjusting 87-112dB Back-Up Alarm | Steam Cleanable, Multi-Voltage 12V-24V

Advanced Dual-Function Audio Versatility: Easily pre-configured upon installation to run as a smart self-adjusting volume alarm or a distinct pulsed warble-tone siren, adapting seamlessly to unique fleet or job site safety mandates.

Intelligent Self-Adjusting Acoustic Monitoring: When set to self-adjusting mode, the internal circuitry constantly samples surrounding ambient environment noise and automatically regulates its output to stay 10 decibels nominal above surrounding sound levels—scaling dynamically from 87dB up to a loud 112dB.

Steam-Cleanable & Pressure-Wash Safe: Constructed with premium, fully sealed internals to tolerate high-pressure fleet power washes and hot commercial steam cleaning without risking internal moisture ingress or short circuits.

Rugged Glass-Filled Nylon Housing: Encased in a high-impact, industrial-grade glass-nylon composite shell designed to survive severe chassis vibrations, chemical exposure, heavy impact, and extreme road debris.

Secure 3-Bolt Terminal Configuration: Features a heavy-duty, threaded 3-bolt stud terminal interface using #8-32 UNC studs to guarantee an absolute, vibration-proof electrical connection over rough terrain.

Integrated 4-Screw Bracket Mount: Equipped with a built-in, 4-hole universal mounting bracket (0.328" bolt hole diameter) for stable, heavy-duty mounting directly onto heavy truck frames, utility bodies, or industrial equipment bays.
