The detector is supplied in A1R mode (fixed threshold at 58°C and thermovelocimetric detection), but can be configured (using the EDRV1000 controller) in the following modes: B (Fixed threshold at 72°C); A2S mode (Fixed threshold at 58 °C); BR mode (Fixed threshold at 72 °C with thermovelocimetric detection). Thanks to its high versatility, it can be used in all conditions where it is difficult to detect smoke or there is a risk of a false alarm.
