Ajax EN54 Fire Detection (Heat/Sounder) White

EN54 FireProtect Jeweller detectors combine certified reliability with effortless installation. This wireless series includes addressable point smoke and heat detectors, some of them combined with built-in fire alarm sounders. Each detector provides best-in-class detection accuracy thanks to Ajax's patented smoke chamber with a dual-spectrum optical sensor and two accurate thermistors. With built-in communicators, long battery life, and stable radio communication, the devices are ready for different-scale projects. No need to open the enclosure or run cables — installation and configuration take just minutes via Ajax apps. Early service notifications and automated maintenance reports via Ajax PRO Desktop ensure the system stays easy to support for years. Two built-in thermistors detect a rapid temperature rise or threshold exceedance. They trigger an alarm when a rapid temperature increase or static temperature is detected. Heat detector modes — A1, A1R, A1S, B, BR, BS, C, CR, CS, or a fixed temperature2 — can be selected in an Ajax app. This approach ensures fast and accurate detection of flaming fires or heat build-up caused by smoldering, which is critical for timely response.
