SF100 WSST is а conventional fire alarm sounder with a strobe. The sounder supports 32 different
alarm tone types selectable via DIP switches on the PCB.
The sounder has two inputs for connection to a conventional fire alarm panel:“Alarm” and “Evacuation”.
In case the two inputs are used, the “Evacuation” input always has a priority in activation.
SF100 WSST is designed for indoor use only. The sounder is easy for installation and consists of
three parts: mounting plane basis, sounder and strobe combined in a common body and a plastic
The conventional sounder SF100 WSST is certified according to standards EN54, part 3 and part 23.
