System Sensor

Since 1984, System Sensor has worked hard to become one of the largest manufacturers of fire detection and notification equipment in today's market. The company is headquartered in St. Charles, Illinois and became part of the Honeywell Life Safety Group in the year 2000. As specialists in smoke detection and carbon monoxide, they take pride in their research and development of new technologies. As a result, System Sensor produces a line of products that are reliable, sophisticated and designed for real-world applications. Whether you're looking for conventional detection in the form of smoke detectors and CO detectors or detectors with strobes and horns (such as the Spectralert Advance) or even sprinkler system monitors or HVAC system monitoring, System Sensor has something that will fit your required application. If you are looking to replace an ancient smoke detector, one of their most popular lines of smoke detector, the i3, consisting of both 2 and 4 wire smoke detectors, is easy to install for most wired monitored system. They even have a new range of intelligent smoke detectors, providing more reliability and less false alarms.

System Sensor has one of the most diverse lines in the smoke detection industry. With their new i3 Series, they are taking a much more unique direction in reducing costs with simple installations, intelligence of operation and instant inspection. System Sensor's carbon monoxide detectors as well as their heat and beam detectors also provide an effective solution when seeking a specialty detection system. System Sensor 2-wire and 4-wire smoke detectors have cemented their position as an industry standard for both commercial and residential systems.

System Sensor Smoke Detectors

Detect the presence of smoke as quickly as possible with a system sensor smoke detector. Smoke detector devices by System Sensor use photoelectric technology to detect smoke and issue a signal to a fire alarm control panel. Photoelectric or optical smoke detectors use light to detect the fire and perform exceptionally well when protecting the area against slower, smoldering fires such as a smoldering mattress. The alarm would usually buzz off as soon as a light beam hits the sensor within the light-sensing chamber inside the alarm panel. The panel is smart enough to reset the zone automatically when an alarm is cleared. This automated operation will stop sounding the device. The fire detection devices offered by System Sensor have different models that are either a photoelectric type (Model 2W-B, 4W-B) or a combination photoelectric/thermal (Model 2WT-B, 4WT-B) enhanced with a heat sensor rated at 135 Fahrenheit. Before most smoke detectors would require a separate aux power supply, a transformer and backup battery. However, with system sensor technology, there is no need for an auxiliary power supply and wiring is much easier. If you are wondering where to buy high-quality, easy to install smoke detectors with fantastic detection, then you have come to the right place.
