Installing The Cbc; Step 5: Installing The Avaya Partner Contact Closure Adjunct; Installing The Contact Closure - Avaya G450 Installing And Upgrading

Installing the CBC

Before you begin, be sure the telephone lines are cross-connected to the appropriate media
module(s).
1. Connect one end of the conductor to a telephone cable building entrance protector ground
that is connected to an approved ground.
2. Route the rest of the conductor next to the exposed telephone cables being protected until
they reach the cross-connect nearest to the telephone system.
3. Terminate the other end to the single-point ground block provided for the telephone
system.
Note:
Position the non-exposed telephone cables at least 12 in (30.5 cm) away from
Note:
exposed telephone cables whenever possible.
Step 5: Installing 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 CCA port on the G450 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 CCA 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.

Installing 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 G450 front
panel. Use a 24 gauge minimum telephone wire, no longer than 200 ft, with a standard four
wire RJ-11 connector.
