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. In the 1990’s, System Sensor also had introduced 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, except 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 was discontinued In Late 2023.

'''Late 1980s:''' The company introduced the Multi-Alert Sounder Series (MASS), a line of multi-tone notification appliances.

=== Notification appliances ===

==== MASS Series ====

[[File:System Sensor MASS ADA.jpg|thumb|250px225px|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. 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 [[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-complaintcompliant strobe. In 1997, the MASS was replaced by the SpectrAlert series.{{Citation needed|date=December 2024}}

==== PA400 Series ====

Line 43 ⟶ 47:

==== SpectrAlert Series ====

[[File:System Sensor SpectrAlert Classic Horn Strobe.jpg|thumb|250px225px|A SpectrAlert horn 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]]es.

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.

The SpectrAlert Advance was introduced in 2006 to replace the Legacy SpectrAlerts.{{Citation needed|date=April 2024}} Its main features were an updated mounting plate wiring design that allows for easier installation, contains more candela options, and has an updated design. The Advance came in the same models as the original SpectrAlert, with the addition of mini horns, and low frequency sounders, which were released in 2014.{{Citation needed|date=December 2024}}

All SpectrAlert Advance products, except for the outdoor models and mini horns, were discontinued by February 12, 2020.<ref>{{Cite web |date=February 12, 2020 |title=SpectrAlert Advance Notification EOL |url=https://buildings.honeywell.com/content/dam/hbtbt/en/documents/document-lists/system-sensor/announcement/SS-Web-SpectrAlert-Advance-Indoor-EOL-2020-02.pdf |access-date=December 4, 2024 |website=System Sensor}}</ref>

In 2017, the System Sensor L-Series was released, replacing the SpectrAlert Advance series.{{Citation needed|date=April 2024}} New features included a new 3000 hertz tone, more candela options, lower power draw, and an updated design. The low frequency devices were released in 2018. The new low frequency devices had Temporal 4 for Carbon Monoxide (CO) operations. As of late 2023, the xenon L-Series devices were discontinued.<ref name=":0" />

On March 14, 2024, some L-Series low frequency sounders have been recalled due to potential for low volume or no sound output.<ref>{{Cite web |date=March 11, 2024 |title=Operational issues on the System Sensor Low Frequency Sounder models |url=https://buildings.honeywell.com/content/dam/hbtbt/en/documents/document-lists/system-sensor/recall-notifications/SSR24.1SB%20-%20System%20Sensor%20Low%20Frequency%20Sounder%20Notice%20with%20DEALER%20Certificate%20of%20Complicance.pdf |archive-date= |access-date=May 16, 2024 |website=System Sensor}}</ref>

==== LED L-Series ====

In October of 2023, System Sensor announced the release of a new LED L-Series that uses lower current draw to replace the xenon L-Series devices.<ref name=":0">{{Cite web |title=Product Announcement: L-Series with LED Notification Appliances |url=https://buildings.honeywell.com/content/dam/hbtbt/en/documents/downloads/System-Sensor-L-Series-LED-Announcement-23.2SS.pdf |access-date=May 16, 2024 |website=System Sensor}}</ref>

=== Detection devices ===

==== 1400/2400 Series ====

In the 1990’s1990s System Sensor introduced a line of smoke detectors including the System Sensor 1400 2-wire Ionization detector and the 2400 2-wire Photoelectric detector.

==== i3 Series ====

In the 2000’s2000s, System Sensor introduced the i3 line of smoke detectors, which came in 2 and 4 wire models. These devices have a feature which they will poll with the fire alarm panel when the sensor is dirty, causing a trouble condition on the panel.
