Conventional Sounder Strobe, SFP-CSS-004

The SelectFire Plus SFP-CSS-004 Conventional Sounder Strobe is designed for use within conventional fire alarm systems and combines a high-output audible alarm with a flashing visual alarm device in one unit.

The sounder is approved to European Standard EN54-3:2014+A1:2019, while the integrated visual alarm device is approved to EN54-23:2010.

The strobe uses high-efficiency LEDs to produce a bright flashing white light, helping alert deaf or hard-of-hearing occupants and providing effective warning in high-noise environments where an audible alarm alone may not be sufficient.

The catalogue states that the visual alarm device provides a minimum illumination level of 0.4 lux throughout its stated coverage volume, helping ensure that the signal can be seen in both daylight and darkness.
