Duress Option

This lock is actually S&G Model 6738-1, but is best known as 6730 with Duress. This lock appears most often on older Chili's safes with a dial instead of LaGard keypad. Note that Chili's may call in under the name Brinker International.
Operation: To open the door and trigger the silent alarm, add 10 to the first number of the combo. For example, if the real combo is 50-25-50, using the combo 60-25-50 will trigger the silent duress alarm. Entry to the safe is otherwise normal.
Setup: The switch is located on the side of the lock body nearest the container. To wire the alarm for a normal closed alarm loop connect wires in series to terminals C and NO. To wire the alarm for a normal open alarm loop connect wires in series to terminals C and NC. For low voltage applications use the normal open connectiion.
