Description
The Zeta Fyreye MKII MKII-AOH (Part no. 80-228) is an advanced addressable multi-sensor fire detector engineered by Zeta Alarm Systems for commercial, industrial, and institutional fire safety applications. By integrating a photoelectric light-scattering smoke chamber with an electronic thermistor thermal sensor inside a low-profile white housing, the unit monitors both smoke particle obscuration and rate of temperature rise (Class A1R). Managed by an internal 8-bit MCU microprocessor executing intelligent signal processing, the detector rapidly detects fast-flaming combustion and slow-smoldering fires while delivering superior immunity to false triggers caused by transient atmospheric changes. Operating on a 17V to 28V DC addressable loop, it supports digital soft addressing via the MKII handheld programmer (1–240 address range), features twin clear 360-degree visual status LEDs, supports remote LED indicator output, and complies fully with LPCB, EN 54-5, and EN 54-7 standards.
Features
- Integrated Short Circuit Isolation: Equipped with a built-in loop isolator that isolates cable short circuits to maintain communication across the rest of the loop.
- Combined Opto-Thermal Detection: Features an optical sensing chamber coupled with an A1R rate-of-rise thermal sensor for early response to both slow-smoldering and rapid-flaming fires.
- Soft-Addressing Protocol: Simplifies setup and commissioning by allowing electronic address assignment via an external hand-held programmer tool.
- Automatic Drift Compensation: Continuously adjusts internal threshold levels to compensate for ambient dust accumulation and avoid nuisance alarms.
- Dual 360-Degree LED Indicators: Designed with twin LEDs positioned on opposite sides to ensure complete omnidirectional visual polling and alarm status verification.
