About System Sensor​​ Founded in 1984, System Sensor is a global manufacturer of fire and life safety devices, specializing in smoke detection, carbon monoxide detection, ​and notification technology for world-wide applications. Detectors need to be checked periodically, ideally once a week, and the batteries changed when required, at least once a year. Smoke alarms sound an alarm when they sense the presence of smoke particles in the air, while carbon monoxide detectors sound an alarm when toxic levels of the invisible and odorless gas are detected. Install one device next to each existing alarm for sound detection or connect it directly to your alarms for activation.
