System Sensor is a St. Charles, Illinois company involved in the research, development and manufacturing of fire protection products. System Sensor is part of Honeywell Life Safety Group.[1]


System Sensor was founded in 1984[2] by the Pittway Corporation to address the unique product requirements of the fire alarm industry. That same year, the MASS series was introduced. Around 1987, their mini horns were also introduced. They were discontinued in the 2000s. In 1995, due to the ADA requiring all strobes have clear lenses, the MASS series was replaced with the MASSADA series, though production of the MASS series continued for a few more years. The MASSADA series was discontinued in 2008. In 1997, System Sensor introduced its SpectrAlert series of notification appliances. In 2008 System Sensor discontinued the SpectrAlert product line in favor of the SpectrAlert Advance Product Line.[3] System sensor released the Spectralert Advance low frequency horns and horn strobes in 2013. System Sensor was purchased by Honeywell in the early 2000s, and currently manufactures notification appliances, smoke detectors, waterflow switches, and HVAC monitoring systems.
