Rules met. Conventions shattered.

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 long-range radio communication, the devices are ready for different-scale projects. Installation and configuration take minutes via Ajax apps. Early service notifications and automated maintenance reports via Ajax PRO Desktop ensure the system stays easy to support for years.

Smoke detection

The patented smoke chamber is dustproof, insect-resistant, and requires no regular cleaning.

The dual-spectrum optical sensor has blue and infrared LEDs that emit light with different wavelengths.

The HazeFlow 2 algorithm analyzes data from the dual-spectrum optical sensor and compares it to a specified pattern to distinguish smoke from vapor or steam.

Heat detection

Two thermistors are used for accurate detection of flaming fires and rapid temperature rise.

A1, A1R, A1S, B, BR, BS, C, CR, CS, and fixed temperature modes are supported.

Detection modes are selected in the app.
