Edwards Signaling 5520-AQ 5520-AQ D2 Class Horn and Siren, suitable for outdoor applications, 24AC/DC, 0.85A

For reliable outdoor audible notification in security, fire, and facility monitoring applications, the Edwards Signaling 5520-AQ Class D2 horn and siren delivers versatile, high-performance alerting where it matters most. This Duotronic series signal switches between horn and siren modes via an internal tamperproof control, enabling both continuous alarms and coded tones for evacuation, paging, or shift signaling. Designed for easy installation, the universal Adaptaplate and box-/wall-mount form factor let installers prewire the plate and simply snap the unit in place, reducing on-site labor. The 5520-AQ supports 24VAC/DC operation (0.85A AC; 0.35A DC) and produces a high-decibel output (up to 124 dB) to penetrate noisy environments. Rugged, weatherproof construction—and compatibility with the Edwards 349 back box—makes this unit ideal for outdoor and industrial sites that require dependable, low-maintenance audible alerts. Specify the Edwards 5520-AQ for security and surveillance systems, industrial facilities, schools, and transportation hubs that need clear, powerful notification.
