EST Edwards SIGA-HRS Fire Alarm Heat Detector Head and Base - This intelligent thermal sensor provides rapid, reliable detection of temperature changes in critical life-safety environments. Engineered for seamless integration with Signature Series loops, this unit ensures consistent monitoring performance - 135°F fixed temperature threshold - 15°F per minute rate-of-rise response - 15.2 to 19.95 VDC operating voltage - 45 µA standby current - 40 µA alarm current

Compared to legacy mechanical heat sensors, the SIGA-HRS utilizes advanced digital processing to minimize false alarms while maintaining precise sensitivity standards. This modern design avoids the maintenance-heavy requirements of older analog systems, offering a more robust and responsive solution for high-stakes fire protection infrastructure.

Advanced Sensing Technology and Operational Performance

The unit features sophisticated environmental compensation, ensuring that thermal thresholds remain accurate even as operating conditions shift. By leveraging the data-rich communication protocol of the Signature series, it transmits specific diagnostic information back to the control panel, streamlining system upkeep and verification. This digital precision allows for faster response times in developing fire scenarios, providing a higher level of reliability for commercial and industrial applications.
