GE Interlogix Horn/Strobe Series is designed to comply with the Americans with Disability Act (ADA) and meet UL standard 1971 requirements for emergency signaling devices for the hearing impaired. The horn/strobe series features a unique candela intensity field selector switch for alternating the candela output from 15cd to 30cd (75cd on axis). The horn provides two different field selectable tones, and a High/Low output setting that can be achieved with the use of mini jumpers located on back of the unit. The strobe housing is clearly labeled with vertical “FIRE” lettering and is polarized for connecting to supervised fire alarm circuits. The strobe is designed with a xenon flashtube and provides a candela intensity field selector switch for maximum performance. The horn/strobe series is available in red and white housing 24VDC models. These models can be synchronized by using the 13–472 Sync Module to comply with NFPA recommendations concerning photosensitive epilepsy when installing 2 or more visual appliances within the field of view. The strobe signals are listed for indoor use, wall mount, under UL 1971 Standard.
