The Silent Knight IDP-PTIR-W is an intelligent, addressable multi-criteria detector in a white housing that combines photoelectric, thermal, and infrared (PTIR) sensing in one head to judge a fire condition from three signal types at once. Cross-checking all three sensing elements reduces both missed real fires and nuisance alarms compared to a single-technology detector.

- Combines photoelectric, thermal, and infrared sensing in a single addressable head
- Multi-criteria logic improves detection confidence and cuts nuisance alarms
- White housing for Silent Knight/Farenhyt intelligent addressable systems
Technical Specifications
