Lock Relay Connection


Device Not Sharing Power with the Lock
Notes:
1. The system supports NO LOCK and NC LOCK. For example the NO LOCK (normally
opened at power ON) is connected with 'NO1' and 'COM1' terminals, and the NC
LOCK (normally closed 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
from affecting the system.
Do not reverse the polarities.
