Edwards SIGA-HFD Heat Detector

The Edwards SIGA-HFD is a commercial addressable fixed temperature heat detector designed for reliable fire detection in environments where smoke detection may not be suitable. As part of the Edwards Signature Series, it utilizes advanced thermal sensing technology and electronic addressing to provide dependable detection, continuous self-diagnostics, and simplified system maintenance.

The detector incorporates an onboard microprocessor that continuously monitors detector performance, stores operational data in nonvolatile memory, and communicates with the fire alarm control panel for fast, accurate alarm reporting. Its low-profile design and dependable operation make it suitable for a wide range of commercial fire alarm installations.

Product Functions

• Detects fixed temperature fire conditions
• Reports alarm conditions to the fire alarm control panel
• Provides electronic device identification
• Continuously supervises detector status
• Performs onboard self-diagnostics
