Notes:
1. The system supports NO LOCK and NC LOCK. For example the NO LOCK (normally open
at power on) is connected with 'NO1' and 'COM1' terminals, and the NC LOCK (normally close
at power on) is connected with 'NC1'and 'COM1' terminals.
2. When electrical lock is connected to the Access Control System, you must parallel one FR107
diode (equipped in the package) to prevent the self-inductance EMF a ecting the system.
! Do not reverse the polarities.
