Using a Paging Unit
When you use a paging unit, connect an external paging amplifier and a loud speaker to the paging unit.
Power Failure
When a power failure occurs, you can still use the system for approximately 20 minutes if it has a built-in
battery. However, it will not work when the battery is completely discharged. Connecting a Power Failure
Telephone (SLT) to the system allows trunk line to cut through directly to SLT during a power failure, en-
abling outgoing and incoming exchange line calls.
Sensor
A sensor can be connected to the system through the sensor terminal on the doorphone/doorlatch interface
cord. When a sensor detects visitors or any other alarms, it sends a signal to the key telephone.
