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 transparent cover.
The conventional sounder SF100 WSST is certified according to standards EN54, part 3 and part 23.
- 32 sound types selectable from the panel
- Piezo sounder
- White LED flash
- Transparent plastic case
- Certified according to standard EN54 – part 3 and 23

SF100 RSST is a conventional wall mount sounder and strobe, designed for installing in conventional fire alarm systems.
Supports 32 different tone types and two sound levels, controled by jumpers. SF100 RRST is equipped with two additional separate inputs for Alarm and Evacuation events. The tone sounds of the inputs are different for easy recognition from the users on the protected site. The Evacuation event is with the highest priority.
Certified according to standard EN54, part 3.
