Emergency Notifications Speaker Expander Plate

System Sensor introduced its new SpectrAlert Advance Dual Strobe and Dual Strobe with speaker expander plates for emergency communications system and mass notification system applications. The new plates enable installers to combine the functions of two to three devices on a single mounting plate and back box, lowering the overall cost of the installation and improving aesthetics by requiring fewer devices on the wall, according to the company. With a plug-in design, the expander plates include a UL 1638-listed amber lens strobe for Private Mode General Utility Signaling that meets DOD specification standards. They can be used in 12-volt or 24-volt systems and can be paired with a fire-rated SpectrAlert Advance strobe or speaker strobes. Outdoor speaker strobes now include white wall-mount and ceiling-mount clear lens, ALERT-printed devices, as well as a white ceiling-mount high candela clear lens speaker strobe with no printing.
