The compliant, fire approved sounder visual alarm device (VAD) detector base, is one of the most flexible and useful devices in Eaton's addressable range of fire devices.
Including are all the features of the addressable sounder detector base, as well as a powerful LED beacon. Meeting the 4 lux output, the LED beacon is certified to be used as an open class VAD.
There are two main options when specifying either adding a detector to create a sounder VAD detector or adding a cover plate to form a discrete sounder VAD. The device is compatible with Eaton's full range of addressable detectors and fire systems.
