Step 4: 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 G250 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.
To install the contact closure:
1. 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.
2. Note which device is connected to each relay. You will need this information for
configuration.
3. Connect the Avaya Partner Contact Closure adjunct box to the CC port on the G250 front
panel. Use a 24-gauge minimum telephone wire, no longer than 200 ft, with a standard
four-wire RJ-11 connector.
