The System Sensor RK series was a series of UL 1971 strobes that could be added to a Multi-Alert sounder.

History

The RK series was released in 1994 because the UL 1971 strobes in the Signal Strobe series were only usable as remote strobes. These strobes used pigtail wires that could be run through a Multi-Alert sounder.

By 1997, the RK series was discontinued, as the Retro-Plate series provided similar functionality without needing to retrofit wires through a device.
