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. At JMAC supply, we deliver a complete line of conventional and intelligent smoke detectors by System Sensor such as:
