Ajax FireProtect 2 AC (Heat/CO) is a mains-powered combined heat and carbon monoxide detector for indoor residential and light-commercial use. It provides fast heat detection with Class A1R thermistors and chemical CO sensing with up to 10 years service life. The detector connects wirelessly to Ajax hubs via the Jeweller protocol for system-wide interconnection and remote notifications, while maintaining local protection during hub loss. Installation is simplified with the SmartBracket and pre-installed WAGO connectors.
