Multi-Criteria

The Soteria UL Multi-Criteria Detector (Smoke/Heat) is Apollo’s most advanced detector offering suitable for a wide range of applications. It uses Purelight® high-tech smoke sensing technology to detect smoke particles entering the chamber and is fitted with two thermistors for detecting heat. It can be switched to detect smoke, heat, or a combination of both, offering greater flexibility, fast detection, and advanced false alarm management.

  • Fully approved to the latest UL268 7th Edition and FM standards
  • SMART built-in isolator
  • Purelight® optical technology for enhanced smoke detection and false alarm management
  • Supports Overwatch Custom Thresholds
  • Multi-color status LED
  • Backwards compatible with legacy Discovery UL systems
  • Model SA5150-750APO

Photoelectric Smoke

The Soteria UL Smoke Detector is Apollo’s most advanced detector offering suitable for a wide range of applications. It utilizes Purelight® high-tech sensing technology that detects smoke particles entering the chamber and substantially reduces the possibility of false alarms.
