Engineered to meet UL Standard 1480 5th edition, the ULSseries of speaker assemblies provides clear signal reproduction for indoor alarm evacuation and/or voice communication in fire alarm/emergency warning systems, as well as general voice communication for other applications. The assembly includes an 8” single voice coil speaker with a dual cone, 70/25V dual voltage transformer with power tap lugs, parallel input leads, DC blocking capacitor and round or square grille.

The 15-watt speaker delivers excellent sensitivity per UL’s measurement standard of 2W @ 10 feet. This recognized standard assures emergency communications can be heard and understood. The attractive white ceiling grille meets both functional and architectural considerations for unobtrusive life safety speakers and is suitable for use in hotels, apartment complexes, schools, and retail establishments of all kinds.

NOTE: The ULS fire protective signaling speaker assembly must be used with compatible control equipment and appropriate Lowell backbox to maintain UL Listing (order separately).
