1-4b. Main Features - All Call, Group Call, ReCall (practice)

System configuration

Exercise

All Call

• All stations except the Elevator should receive the All Call.
• Only the Reception and the Main Guard should be able to initiate All Call.

ReCall

• Make an All Call with the Reception close to Mr. Edison so acoustic feedback will appear. Use ReCall to avoid this. Are there other possibilities?

Group Call

• Only the Reception and Mr. Galilei should receive Group Call 2. Anyone can initiate the Group Call.

Priority

• If the All Call is initiated while the Group Call is active, the Group Call should automatically disconnect in order to let the All Call get through.
