System Sensor was founded in 1984<ref>{{cite web |title=About System Sensor |url=http://www.systemsensor.com/html/about.html |archive-url=https://web.archive.org/web/20100308105416/http://www.systemsensor.com/html/about.html |archive-date=March 8, 2010 |accessdate=24 October 2009}}</ref> to address the requirements of exclusive industry fire alarm products. Early products included the MASS and PA400 Series. The MASS was a multi-tone device which came in different variants such as a horn/strobe. The System Sensor PA400 was a mini horn. In the 1990’s, System Sensor updated the MASS with an ADA-complaint strobe. Around this time, System Sensor also had a line of smoke detectors, including the System Sensor 1400 and the 2400 2-wire detector. In 1997, the MASS was replaced with the SpectrAlert series. In the 2000’s, System Sensor was acquired from Pitway by Honeywell. Around this time, System Sensor introduced the i3 line of smoke detectors. In 2006, the original SpectrAlert series were replaced with the SpectrAlert Advance. In 2017, the System Sensor L-Series was released. All SpectrAlert Advance products, expect for the outdoor models and mini horns, were discontinued by February 2020. In October of 2023, System Sensor announced the LED L series. The original L Series is planned to be discontinued In Late 2023. {{citation needed|date=November 2022}}

'''==== MASS Series''' ====

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.

In 1993, System Sensor filed a patent for a new strobe that was [[Americans with Disabilities Act of 1990|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-compliant strobe. In 1997, the MASS was replaced by the SpectrAlert series.{{Citation needed|date=December 2024}}

'''==== PA400 Series''' ====

The System Sensor PA400 was a mini horn, with an optional strobe attachment. In 2007, the PA400 series was discontinued and replaced with the MH series sold under the SpectrAlert Advance name.{{Citation needed|date=April 2024}}

'''==== SpectrAlert Advance Series''' ====

[[File:System Sensor SpectrAlert Classic Horn Strobe.jpg|none|thumb|225px|A SpectrAlert Horn/Strobehorn strobe]]

The SpectrAlert series was the successor to the MASS series. The SpectrAlert series included horn strobes, strobes, remote horns, chimes, chime strobes, speakers, and speaker strobes. A main feature of these alarms was the ability to sync them using a System Sensor MDL sync module or the System Sensor sync protocol on a supported [[fire alarm control panel]]. Three years after the initial release of the SpectrAlert series, System Sensor released the ceiling mount SpectrAlerts. This included horn strobes, remote strobes, speaker strobes, and remote speakers. There were multiple generations of the SpectrAlert. The first generation had a screw lock. The second generation, released in the early 2000s, replaced the screw lock with a clip lock. Approximately before 2006, the third generation was released with multi-candela strobes, and replaced the jumpers for the horn tone with [[DIP switch|DIP switches]]. In 2006, the original SpectrAlert series were replaced with the SpectrAlert Advancees.

A few years after the discontinuation of the SpectrAlert series, fire alarm enthusiasts dubbed the SpectrAlert series as "SpectrAlert Classic" indicating that it is the original SpectrAlert line of fire alarm products. The term became popular and is now being used by most fire alarm enthusiasts today.
