Eaton's open class visual alarm device (VAD) for its addressable fire alarm systems offers low current consumption, multiple sound output levels and an energy-efficient LED light source. Soft addressed and loop powered, the range is easily maintained and installed from the system control panel where tones and volume can also be adjusted.
Designed for when an EN54-23 VAD's is required, however, an open class option has been chosen meaning the coverage volume and shape does not restrict mounting height. The 0.4 lux illumination still applies to the open class range.
Available in two options: standard and weatherproof. The weatherproof is rated to IP66 making it suitable for indoor washdown areas such as kitchens, bathrooms and factories and outdoor applications.
