Chapter 14: Configuring contact closure

You can use contact closure to control up to two electrical devices remotely. With contact
closure, you can dial feature access codes on a telephone to activate, deactivate, or pulse
electrical devices such as electrical door locks. You can also activate and deactivate contact
closure using CLI commands. You can only use feature access codes if you configure the
Avaya G450 Media Gateway to use a server with Avaya Communication Manager software. For
more information, see
It is recommended that you use an Avaya Partner Contact Closure Adjunct™ for contact
closure. For more information, see Overview for the Avaya G450 Media Gateway, 03-602058.
An Avaya Partner Contact Closure Adjunct™ contains two relays, one for each electrical
device. You can control each relay in any of the following ways:
When you dial the contact closure open access code, the relay opens (no contact)
●
When you dial the contact closure close access code, the relay closes (contact)
●
When you dial the contact closure pulse access code, the relay closes (contact) for the
●
pulse duration and then opens (no contact)
You can control each contact closure relay manually with CLI commands or with Avaya
●
G450 Manager
Note:
Configuration of the feature access code is performed through the Avaya
Note:
Communication Manager. For more information, see Administrator Guide for
Avaya Communication Manager, 03-300509.
