Secutron MRI-4003-S Sounder Base

Deliver reliable, localized alarm notification where it matters most with the Secutron MRI-4003-S sounder base. This detector base is engineered for the MRI-4000 family, giving security and facilities teams a straightforward way to add audible signaling to fire detection networks. Choose from multiple tone patterns — including the NFPA 72 three-pulse temporal pattern — to meet code requirements and ensure consistent, recognizable alarm signals. Two user-selectable volume levels (low and high) let you adapt alerts for offices, warehouses, or noisy mechanical rooms, reducing nuisance issues while maintaining effective notification.

Beyond compliance, the MRI-4003-S helps streamline monitoring and incident response by delivering distinct, localized sound cues that support surveillance and security workflows. The compact, easy-to-install design lowers installation time and ongoing maintenance costs, making it an efficient choice for commercial, institutional, and industrial applications. Enhance your fire alarm and security monitoring systems with a purpose-built sounder base — add the Secutron MRI-4003-S to your specifications or contact our team for integration guidance.
