The EN54 FireProtect Jeweller detectors combine certified reliability with easy installation. This wireless line includes smoke and heat detectors with addressable points, some of which include built-in alarm sirens. Each detector provides exceptional detection accuracy thanks to Ajax’s patented smoke chamber with a dual optical sensor and two precise thermistors. With built-in communicators, long battery life, and stable radio communication, the devices are ready for projects of different scales.

Installation and configuration are done quickly through Ajax apps, without needing to open the box or run wires. Early service notifications and automated maintenance reports via Ajax PRO Desktop ensure that the system remains easy to support for many years.

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

This approach ensures fast and accurate detection of flaming fires or heat build-up caused by smoldering materials, which is critical for timely response.
