SpectrAlert® Advance speaker strobes can be used outdoors, in wet or dry applications, and provide reliable operation from −40 to 151 °F. They provide a broad frequency response range, low harmonic distortion, and maintain a high sound pressure level at all tap settings to provide accurate and intelligible broadcast of evacuation messages.

These speaker strobes include a variety of features that increase application flexibility and simplify installation, such as field-selectable settings, including candela, speaker voltage and power settings, and automatic selection of 12 or 24V operation enable installers to easily adapt devices to meet requirements.
