Description

The Zeta Fyreye MKII-AHR (Part No. 80-212) is an open-area intelligent addressable Class A1R thermal heat detector engineered for commercial, industrial, and residential fire alarm installations. Built with a dual-thermistor sensing arrangement, the unit continually monitors both rapid rate-of-rise temperature shifts and a 57°C static threshold to ensure rapid alarm triggering in dusty, steamy, or smoky environments where optical detectors cause false alarms. It operates over a 17V to 28V DC loop range on Zeta protocol panels, features dual-addressing capability (8-way binary DIP switch or handheld programmer), an 8-LED ring providing 360-degree omnidirectional visibility, remote indicator output support, and full EN 54-5 certification.

Features

  • Dual Thermal Sensing: Combines rate-of-rise temperature response with a fixed 57°C static heat trigger to detect rapid fire outbreaks as well as slow-heating thermal events.
  • 360-Degree LED Ring: Equipped with 8 perimeter LEDs around the head casing to provide complete omnidirectional visibility for polling and alarm status.
  • Dual Addressing Options: Offers flexible device addressing via onboard binary DIP switches or electronically via a handheld programmer.
  • Base Locking Mechanism: Features an integrated locking tab to secure the head to the base and prevent unauthorized removal or tampering.
  • Remote Indicator Capability: Built with a dedicated terminal output to power external remote LED indicators in concealed space installations.
