Ajax FireProtect Heat detector, reliable and accurate fire protection
The Ajax FireProtect Heat EN54 Jeweller heat detector is designed to offer reliable and accurate fire protection, integrating seamlessly with the EN54 Fire Hub Jeweller control panel. Equipped with two high-sensitivity thermistors, the device detects both rapid temperature increases and the exceeding of predetermined heat thresholds.
This detector complies with EN 54-5 standards for Class A1, B and C heat detectors, and supports both incremental (R) and static (S) modes. The different detection modes-A1R, A1S, BR, BS, CS-can be easily configured via the Ajax app, allowing the device to be tailored to the specific needs of the installation environment.
The detector is ideal for both fires with an immediate flame and latent fires that cause a gradual buildup of heat. The alarm is triggered quickly, enabling timely intervention to protect people and property.
Accurate and rapid detection
With two built-in thermistors, the device recognizes both rapid temperature increases and predefined heat thresholds, ensuring maximum fire protection.
Customizable modes
Different thermal detection modes (A1R, A1S, BR, BS, CS or fixed temperature) can be selected via the Ajax app, for perfect adaptation to the type of environment.
Easy and immediate installation
Pre-installed CR123A batteries make the detector ready to use, without the need for additional tools or complex work.
Total compatibility
Works with the Ajax EN54 Fire Hub Jeweller control panel, integrating into existing fire systems, and contributes to comprehensive security management.
