The Safera Aurora Stove Guard is a safety device designed to prevent cooking-related hazards by monitoring the cooktop and automatically cutting off power if a dangerous situation is detected. It is compatible with most electrical cookers, hobs, and ovens intended for household use, including traditional cast-iron, ceramic, and induction cookers, as well as those equipped with timers, afterheat indicators, child-proof locks, or integrated switch-off systems. The system is suitable for cookers up to 90 cm wide.
Function Description:
The Stove Guard system consists of a sensor unit (A), a power control unit (C), and a remote control (D). The sensor unit is typically mounted on the ceiling above the cooktop and continuously monitors the cooking area for signs of overheating or unattended cooking. If a dangerous situation is detected, the sensor unit communicates wirelessly with the power control unit, which then cuts off the power supply to the cooker. The remote control, which has identical button configurations to the sensor unit, allows users to operate all functions of the stove guard.
The system features an "Alarm limit settings" mode (Mode 1) where users can adjust the sensitivity of the alarm based on the installation height of the sensor unit. The default alarm limit is 8, recommended for installation heights between 1.6 and 1.7 meters. The system also includes a "Manual setup of the wireless connection" mode (Mode 2) for re-establishing communication between the sensor and power control units, for example, when replacing either unit. A "Manual calibration of the cooker type" mode (Mode 3) allows users to specify whether the power control unit is connected to both the cooker and oven or only the cooktop, optimizing the system's performance. Finally, a "Testing and adjusting AUX-connection" mode (Mode 4) is available for configuring and testing auxiliary output signals.
The sensor unit employs an auto-recognition feature to identify the cooker type during initial cooking use, which helps minimize false alarms. If the sensor unit is removed from its original mounting position after auto-recognition, the stove guard will prevent the use of the cooker and oven until it is reinstalled correctly.
