Zeta Intrinsically Safe Flame Detector (ZIS-FLD) – Explosion Hazard Area Flame Detection

Product Description:

Introducing the Zeta Intrinsically Safe Flame Detector (ZIS-FLD), your reliable guardian in the face of fire hazards within explosion-prone environments. Designed to swiftly detect and signal the presence of flames, the ZIS-FLD is your first line of defense in safeguarding against potential disasters. This cutting-edge flame detector is engineered for compatibility with Zeta fire alarm system control panels, ensuring your safety is never compromised.


  • Intrinsically Safe (IS): The ZIS-FLD flame detector is intrinsically safe, making it suitable for use in areas with explosion hazards. It complies with stringent safety standards, providing peace of mind in high-risk environments.
  • UV Flame Detection: Utilizing its UV-sensitive sensors, the ZIS-FLD reacts to flame radiation with a wavelength of approximately 200 nm. This precision ensures accurate and rapid flame detection, minimizing the risk of fire escalation.
  • Resistance to Artificial Light: The ZIS-FLD detectors are impervious to artificial light sources lacking UV radiation. This resilience prevents false alarms, allowing you to trust in its reliability.
  • Quartz Glass Construction: The active surface of the ZIS-FLD detector is crafted from quartz glass, ensuring durability and longevity. It’s imperative to maintain the cleanliness of this surface and avoid touching it with bare hands.
  • ATEX Certified: The ZIS-FLD detector proudly boasts the ATEX certificate from the Central Mining Institute (No. KDB 04ATEX170X). Additionally, it has been granted a spark-proof feature (II 2G EEx ib IIC T6), enhancing its safety credentials.
  • Wide Detection Range: With a maximum detection distance of 17 meters (second class of sensitivity) and a generous 120-degree viewing angle, the ZIS-FLD covers a broad area, ensuring comprehensive flame detection.


  • Model: ZIS-FLD

The installation of ZIS-FLD detectors should be executed with careful consideration. Avoid direct sunlight falling directly on the sensor for optimal performance. These detectors are versatile and can be installed on ceilings or walls, depending on your requirements. Depending on your fire alarm system, you can use conventional or addressable bases, but please note that ZIS-FLD detectors should be installed exclusively in ZIS33 bases for compatibility. To enhance visibility, connect the WZ-31 alarm indicator for an additional optical alarm signal.

Invest in the Zeta Intrinsically Safe Flame Detector (ZIS-FLD) to fortify your fire safety measures in environments where safety is paramount. Trust in its ATEX certification, wide detection range, and UV-sensitive technology to provide the utmost protection against fire hazards.

Ensure the safety of your property and personnel with the ZIS-FLD flame detector. Order yours today and experience unparalleled fire detection technology.
