Delay Timer and Buzzer Lock Wiring connection :
Red Wire: 12v dc for E M Lock and external buzzer.
Black Wire: 0V DC For E M Lock
White Wire: 0V for External Buzzer.
This lock is working for door lock with delay timer for buzzer sound 1 second to 300 Second set by you. 1 internal small buzzer inside lock and if you want external buzzer please connect red +12v to buzzer +12v white 0v to buzzer if you don't use external buzzer please do not connect white wire otherwise it will damage your driver transistor. Please tape it properly.If you want to change delay time, first switch off the power supply change delay time then again switch it on. delay time will be change 1 to 300 second this function you can use with 280 kg surface mount E M lock with inbuilt delay timer buzzer circuit with external buzzer or if normal E M lock already mount , you can use only delay timer buzzer circuit with external magnetic sensor shown in product photo ( black box ) .
