Description

• 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.
