Buzzer VAD Addressable Fire Alarm System Eaton CASB393 and CASB393WP
Eaton's Open Class Visual Alarm Devices (VAD) for its addressable fire alarm systems offer low current consumption, multiple audio output levels and an energy efficient LED light source, Rated soft addressing and loop power supply, range is easily maintained and set up the system control panel where tone and volume can also be adjusted ,However, designed for when EN54-23 VAD is needed , an open layer option has been selected which means that the volume and shape of the coverage do not restrict the mounting height. Brightness 0.4 lux still applies to the open class range ,Available in two options: standard and weather. Weather resistant rated IP66, suitable for indoor washout areas such as kitchens, bathrooms, factories and outdoor applications
