The Sonos Pulse Sounder Beacons from Klaxon are Visual Alarm Devices (VADS) with patented Pulse Alert Technology that exceed the illumination requirements of EN54-23 while also providing a 97dB sound output. The Pulse Alert Technology maximises system efficiency by minimising power consumption and enables the coverage pattern to be fixed at the optimum performance level. The synchronised flash protects everyone including people prone to photosensitive epilepsy. Wall or ceiling mounted beacons are available with either a white or red flash and white or red housing. Applications include hotel, office, factory floor and machine shop.
