  • Dual-Sensor Technology: Combines photoelectric smoke detection with a fast-acting thermal sensor for enhanced accuracy.
  • Smoke Detection Range: Sensitivity from 0.2% to 3.1% per foot obscuration.
  • Heat Detection: Selectable fixed-temperature or rate-of-rise settings for customizable performance.
  • True Sense Intelligence: Analyzes combined smoke and heat data for precise detection.
  • Digital Communication: Transmits analog sensor data to the control panel via ID Net two-wire communications for real-time monitoring.
  • Compatibility: Works with Simplex 4007ES, 4010ES, 4100ES, and 4100U (software revision 11 or higher) fire alarm control panels.
  • Software Filtering: Compensates for environmental factors (e.g., dust, dirt) and component aging for consistent reliability.
  • Mounting: Requires a compatible Simplex base (e.g., 4098-9792, sold separately).
