Simplex® 4098-9602 detectors combine photoelectric smoke detection technology and quick response thermistor-based heat detection technology into a sophisticated, intelligent detector that analyzes each of these activities and their combination to determine whether alarm conditions are present.

Four Detection Modes. An onboard microprocessor provides four independent detection modes: photoelectric detection with TrueAlarm sensitivity drift compensation, fixed temperature heat detection, rate-of-rise temperature heat detection, and TrueSense photoelectric/heat trending analysis and alarm detection. If any of these alarm conditions are experienced, an alarm is initiated.
