security (for ex. Intrusion alarm systems, etc.) the power supply of the
device must be connected to a buffer power supply system so that, in the
event of long mains failure, the decoder performance is not jeopardized.
Deletion of codes stored in the decoder
All previously stored codes can be deleted by pressing the reset pushbutton P1 for 3
seconds (fig. 3D). Moreover, by pressing pushbutton P1, the output relay will be de-
energized.
