Line 35: ==== MASS Series ==== [[File:System Sensor MASS ADA.jpg\|thumb\|250px\|An [[Americans with Disabilities Act of 1990\|ADA]] compliant version of the MASS.]] The MASS was multi-tone and came in remote horn and horn strobe models as well as remote strobe models, and speaker strobes and remote speakers. The MASS series was originally sold under BRK Electronics and later under System Sensor. It featured a xenon flash tube housed under a translucent white plastic ~~(Dubbed "Frosted Strobes" by enthusiasts)~~. The original MASS series used break off tabs to change the tone meaning that once the tone is changed, it is permanent. The MASS series was later on updated to use jumpers rather than break off tabs. In 1993, System Sensor filed a patent for a new strobe that was ADA compliant. It featured a clear lens and a reflector to distribute the light as well as higher candela options, the minimum being 15 candela. Soon after, System Sensor implemented the ADA-complaint strobe. In 1997, the MASS was replaced by the SpectrAlert series. ==== PA400 Series ====
