The SS-SRK Strobe, one of the System Sensor SpectrAlert Advance notification appliances, simplifies installations with features such as plug-in designs, instant feedback messages to ensure correct installation of individual devices, and field-selectable candela settings. This strobe is designed for outdoor wall-mounted applications. SpectrAlert products can be used in either DC or full-wave rectified (FWR) systems (12 V or 24 V). If required, the SSMDL module can be used to provide synchronization.
