The DA-04 module is an intelligent circuit, that connected to the bell of a door from any house or local, is able to memorise a melody played on it and to record it. Once this operation done, the module will connect the included relay output, only when the person who press the bell plays the exact melody previously recorded, controlling then the access to this local. Otherwise, the bell will act and ring as a normal bell. Output time adjustable between 1 and 4 sec. It includes an auto-blocking against failed access attempts, outputs for open door push button, push button for the ring, leds and P.I.P. Power Supply: FE-103
