Smoke Detector System Sensor 22051E-46-IV Optical Analogue

The 22051E/EI photoelectric smoke detector features a completely new detection chamber design, the result of many years of research and design by System Sensor. This provides improved response, reduced sensitivity changes caused by dust and fewer false alarms due to insect intrusion and other debris. The plug-in uses sophisticated processing circuitry that includes smoothing filters to eliminate transient environmental noise conditions that may be the cause of unwanted alarms. The devices are controlled by embedded software that runs complex algorithms that further improve resistance to false alarms and increase detection speed.
