Ajax FireProtect 2 AC (Heat/Smoke/CO) Jeweller
FireProtect 2 AC combines three sensors in one device: smoke, heat, and carbon monoxide. The patented smoke chamber with HazeFlow 2 algorithm ignores steam and minimizes false alarms. Two thermistors instantly react to rapid temperature rise, while the chemical CO sensor warns of danger even before critical gas levels are reached. The built-in siren (85 dB) and synchronized alarm feature ensure that alerts are heard everywhere. The detector operates on 110–240 V~ mains power and includes a backup battery.
