Installation
Step 1: Determine the Doorphone Directory Number
Up to four Doorphones can be installed on a Norstar system. Each is assigned a
Directory Number (DN) by the KSU.
To determine the DN of the port to which the Doorphone will be connected, use the
Maintenance Port/DN Status facility (Modular systems only), or refer to the wiring
charts in the relevant Norstar Installer Guide, or:
1. Ensure Auto Set Relocation feature is turned off.
2. Connect a jack and Norstar telephone to the port.
