The Klaxon Sonos sounder has an adjustable volume, with a maximum of 106 decibels, with a choice of 32 tones which have universal approval as they include all of the major international standards. Suitable for any conventional fire alarm system, they are available in red and white, with a choice of a shallow or deep base.
Featuring the Klaxon TimeSaver base, the connections are made to the base when initially wiring the system for a fast and reliable installation. The sounder head can then be twisted onto the base at the commissioning stage and helps to avoid wiring and connection problems often found with other sounders.
The deep base Sonos sounder is weatherproof, with an IP65 rating which makes it suitable for use internally and externally, while the shallow base has an IP21 rating for installation inside. Approved to EN54-3, the sounder has synchronised alarm tones, two alarm stages, and has a wide voltage range.
