Ajax FireProtect Plus BL – Wireless Fire Detector with Smoke, Heat & CO Sensors

Ajax FireProtect Plus BL is a wireless indoor fire detector in a sleek black finish that continuously monitors its environment and immediately triggers an alarm upon detecting smoke, dangerous carbon monoxide (CO) levels, or a rapid temperature rise — either as part of the Ajax system or autonomously via its built-in siren. Designed for professional security installations, it integrates seamlessly with all Ajax hubs and range extenders via the secured Jeweller radio protocol.
