Fyreye MKII-OH Conventional Opto-Heat Detector

The Fyreye MKII-OH is a conventional multi-sensor fire detector manufactured by Zeta Alarm Systems for commercial, industrial, and residential fire safety installations. By combining an optical photoelectric light-scattering smoke chamber with an electronic thermistor thermal sensor inside a low-profile white enclosure, the detector monitors both smoke particle concentration and rate of temperature rise (Class A1R) simultaneously. Managed by an onboard 8-bit MCU microprocessor executing intelligent signal cross-referencing algorithms, the unit responds rapidly to fast-flaming fires and slow-smoldering smoke while delivering high immunity to false alarms caused by transient environmental factors. Operating across a 9V to 33V DC conventional zone loop, it features twin clear-lens 360-degree status LEDs, direct support for remote LED indicator outputs, and full LPCB and CE certifications under EN 54-5 and EN 54-7.
