The EN54 FireProtect Jeweller detection systems combine certified reliability with easy installation. This wireless range includes addressable smoke and heat detectors, some of which feature built-in audible alarm signals. Each detector offers excellent detection accuracy thanks to Ajax's patented chimney with a dual optical sensor and two precise thermistors.

The devices feature built-in communicators, long battery life, and stable wireless communication, ready for projects of various scales. Installation and configuration take only a few minutes via the Ajax apps, without the need to open the enclosure or run cables. Early service notification and automated maintenance reports through Ajax PRO Desktop ensure the system remains easy to maintain for years.

Two built-in thermistors detect rapid temperature rise or threshold exceedance. They trigger an alarm when rapid temperature rise or static temperature is detected. Heat detector functions — A1, A1R, A1S, B, BR, BS, C, CR, CS, or a static temperature — can be selected in the Ajax app.

This approach ensures fast and accurate detection of flaming fires or heat increase due to smoldering fires, which is critical for timely response.
