Edwards 5551F Heat Detector

The Edwards 5551F is a commercial heat detector designed for compatible EST addressable fire alarm systems. It combines fixed-temperature and rate-compensated heat detection with analog temperature reporting, allowing the fire alarm control panel to continuously monitor environmental conditions for reliable fire detection.

The detector communicates temperature data to the control panel during every polling cycle, enabling continuous supervision, automatic diagnostics, and individual device identification. This product is intended exclusively for commercial fire alarm installations.

Product Functions

• Fixed-temperature heat detection
• Rate-compensated heat sensing
• Continuous analog temperature reporting
• Individual device identification
• Automatic detector supervision
• Magnetic functional testing
• Continuous self-diagnostics
• Fire alarm condition reporting through the control panel

Electrical & System Information

The Edwards 5551F operates on compatible EST Signature data circuits where the fire alarm control panel continuously polls each detector. Rather than initiating an alarm independently, the detector reports temperature information to the panel, which determines alarm conditions based on programmed response criteria.

Each detector features electronic addressing, automatic supervision, and controller-operated LED status indication for dependable system monitoring. Up to 96 addressable detectors may be installed on a single data circuit, depending on system design.
