Wireless mains-powered fire detector

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. The carbon monoxide sensor alarms before the concentration level becomes threatening. 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.
