Accuracy through steam, dust, and time

FireProtect 2 AC is a mains-powered detector designed for residential fire safety. The unique smoke chamber does not require regular cleaning, and sophisticated software minimizes false alarms. The dual-spectrum sensor instantly distinguishes smoke from steam, and two thermistors quickly react to the synthetic materials’ burning. Everything meets the latest fire safety standards. Thought-out design, improved mounting panel with WAGO 221 connectors, and in-app settings make the installation process nice and easy, giving an ultimate experience for PRO.

Only real threats considered

In-depth research on materials combustion resulted in HazeFlow 2 — a smoke detection algorithm developed by Ajax. The algorithm contemporaneously analyses and compares data from the dual-spectrum optical sensor to a specified pattern to define smoke from vapour or steam. The detector instantly raises the alarm when pattern dynamics indicate a real case of fire.

Even when it’s fire without smoke

FireProtect 2 is equipped with two class A1R thermistors to detect smokeless fire threats. They give a significant advantage in detecting a rapid temperature rise when synthetic materials burn, or a fire starts from smoldering. Thermistors are located outside the enclosure to eliminate life-saving detection delays. So, FireProtect 2 AC is ready to detect a fire as fast as possible, even if it starts imperceptibly.

Heat alarm

• 10°C increase in temperature within a minute
• Exceeding +64°C

Stable performance for a decade

The detector is powered by 110–240 V~ mains and has a sealed battery to serve as a backup. Even in a power outage, the detector keeps operating smoothly. Designed for the quick and reliable fire detection over its 10-year lifespan.

Always informed, everywhere

For residential fire alarm systems, informing people about fire danger is the priority. FireProtect 2 is equipped with a powerful 85 dB siren to eliminate the risk of missing an alarm. The detector uses impossible-to-ignore tones with different patterns to indicate an alarm or event, so it’s easy to recognize the type of threat and react accordingly.
