The Honeywell XLS-PS Intelligent Photoelectric Smoke Detector gathers analog information from its smoke sensing element and converts it into digital signals. It compares the information to historical readings and time patterns to make an alarm decision. Also, digital filters remove signal patterns that are not typical of fires, thus eliminating most unwanted alarms.
About every 10 minutes, the Honeywell XLS-PS adjusts and updates the sensitivity baseline for its sensing element to compensate for environmental changes caused by dirt, humidity, aging, and small amounts of normal ambient smoke. Furthermore, about once an hour, the microprocessor writes this information to its permanent memory so the detector’s “learned” baseline is not lost. Even though the detector is removed for cleaning.
