The MSR-50R Series remote accessories are designed for use with Air Products and Controls duct smoke detectors to provide the range of functionality required by your local commercial application. The MSR-50R Series comes in two models of the controller: the MSR-50RM which provides a hidden magnet test switch and a pushbutton reset; the MSR50RK provides a key-operated detector test and reset function. Both versions of the MSR-50R accessory are available as either a single gang remote indicator/control, or with the addition of a single gang strobe only or enhanced sounder / LED strobe assembly. As controller only or with the added strobe only or sounder / strobe, all configurations are compatible with standard Decora style cover plates (choice of white, red or stainless steel).
