Federal Signal RSL-SM-GY Radiant Sound Module, 2-Tones, No Volume Control, Gray Housing

For dependable audible signaling in security, surveillance and industrial monitoring setups, the Federal Signal Radiant RSL-SM-GY sound module delivers clear, actionable alerts that drive faster response. This Radiant series sounder produces up to 90 dB(A) at 1 m and offers a two-tone output to differentiate alarm types without additional controllers. Designed for modular integration, the RSL-SM-GY installs directly into Radiant stack light assemblies, enabling mixed visual and audible signaling in one compact unit.

Built for indoor and outdoor use, the gray-housing RSL-SM-GY supports 12–24 VAC/DC or 120–240 VAC operation and achieves Type 4X/IP65 and IP69K protection when gaskets are installed—ideal for manufacturing floors, access control points, loading docks, and perimeter security. Wired connectivity and UL/cUL, CE and RoHS compliance make it straightforward to deploy within existing security and monitoring systems. Note: this model does not include volume control.

Add the RSL-SM-GY to your next alarm stack to enhance detection, reduce response times and standardize signaling across sites. Contact sales to specify mounting bases or order for integration with your surveillance and access control systems.
