AJAX Sensor SB White - FireProtect 2 - Heat Smoke CO

• FireProtect 2 (Heat/Smoke/CO) Jeweller is a wireless fire detector with a built-in siren. Designed for indoor installation. Detects smoke, temperature rise, and dangerous CO (carbon monoxide) level
• The detector operates as part of the Ajax security system, communicating with the hub via the Jeweller secure radio protocol. The hub communication range is up to 1,700 meters without obstacles
• Accuracy through steam, dust, and time
• FireProtect 2 is a next-gen device designed for instant fire detection. The unique smoke chamber does not require regular cleaning, the dual-spectrum sensor distinguishes smoke from steam, the thermistor quickly reacts to the synthetic materials burning, and sophisticated software minimizes false alarms. Everything meets the most modern fire safety standards. Thought-out design, mounting, and the in-app settings make installation straightforward and quick
