Connecting devices
Step 7: Install the Avaya Partner Contact Closure Adjunct

The Contact Closure feature is a controllable relay providing dry contacts for various applications. To 
implement the contact closure feature, you connect an Avaya Partner Contact Closure Adjunct box to the 
CC port on the G350 chassis. The adjunct box provides two contact closures that can be operated in either 
a “normally closed” or “normally open” state. The contact closures can control auxiliary devices such as 
devices that automatically lock or unlock doors or voice recording units. The CC port can be configured 
so that the connected devices can be controlled by an end device, such as a telephone. For example, a user 
can unlock a door by keying a sequence into a telephone keypad.

Follow the installation instructions in the Avaya Partner Contact Closure Adjunct Installation 
Instructions leaflet to install the Contact Closure and connect the auxiliary devices that will be 
activated and deactivated by the Contact Closure relays.

Note which device is connected to each relay. You will need to give this information to the 
supporting technician for the configuration.

Connect the Avaya Partner Contact Closure adjunct box to the CC port on the G350 front panel. 
Use a 24 gauge minimum telephone wire, no longer than 200 ft, with a standard RJ-11 connector.
