Lamphus SoundAlert: a compact, high‑performance siren PA system

Designed for fleets, service teams, and mobile operations, the SoundAlert kit combines a 12V, 100W amplifier with a slim, high-output speaker. In loud city environments, its alert tones cut through background noise, helping your warnings stand out without sacrificing reliability.

Key capabilities at a glance

• Warning tones include wail, yelp, hi-low, plus an electronic air horn for dynamic signaling.
• Integrated horn override lets you trigger the air horn with your stock horn button, keeping hands on the wheel.
• Radio rebroadcast routes GMRS, CB, or HAM audio through the Siren loudspeaker for on-the-go awareness.
• Two 16A auxiliary switches offer flexible control for additional devices or accessories.
• Compact form is just over 2 inches thick, enabling curbside mounting on a bumper or behind a grille.

Flexibility and real-world use cases

This kit is designed to be the backbone of an emergency warning setup, not just a standalone siren. It supports hands-free communication, quick access to alerts, and easy integration with existing gear. The combination of loud output and mounting versatility makes it suitable for a wide range of vehicles and outdoor teams.

• Emergency services-ready alerting for fire, tow, and utility fleets.
• Mobile concessions or service vehicles like food trucks, catering vans, and roving teams.
• Outdoor work machines such as ATVs and UTVs that require clear signals on busy roads.

The siren speaker sits in a slim profile while delivering a broad 118 to 124 dB range, commanding attention wherever it is mounted. With a robust 12V power system, this unit is meant to be paired with other warning gear as the backbone of your alert setup.
