The XLS-HFS and XLS-HRS Intelligent Heat Detectors gather analog information from their fixed temperature and/or rate-of-rise heat detecting elements and convert it into digital signals. An on-board microprocessor measures and analyzes these signals. It compares the information to historical readings and time patterns to make an alarm decision. Digital filters remove signal patterns that are not typical of fires, thus eliminating most unwanted alarms.

Continuously running self-diagnostics update device statistics and store them in a history log in non-volatile memory. The history log contains information such as detector type, serial number, and address; manufacture date; hours of operation; analog signal patterns just before the last alarm; and time and date of last alarm.
