Overview
The EN54 FireProtect (Heat) Jeweller features a high-precision dual thermistor system that accurately detects both rapid temperature spikes and fixed heat thresholds.
This sleek, maintenance free device is engineered for maximum reliability, ensuring instant alarm triggering while preventing false alerts in demanding conditions.
Advanced Enclosure Design
The detector includes a rotatable SmartBracket for easy 90° alignment during setup. Maintenance is simplified by a tool free battery compartment, while tamper protection and an optional mechanical lock ensure the device remains secure and operational over the long term.
Sophisticated Detection Technology
Featuring dual-thermistor technology, this detector provides comprehensive thermal monitoring by reacting to both sudden spikes and fixed temperature limits. By offering selectable modes; from A1R to CS and fixed temperature; via the Ajax app, the device can be precisely tuned for any installation.
This ensures a rapid, reliable response to everything from intense flaming fires to gradual heat accumulation.
Simplified Maintenance
Service management is streamlined through automated maintenance reports that track the real time status of every FireProtect Jeweller. By monitoring battery levels and communication strength via the PRO Desktop app, the system alerts you exactly when maintenance is required.
This data-driven approach eliminates unnecessary site visits while maintaining a verifiable digital trail of system performance.
