Secure Installation
This is a master upstream device configuration and may require Telecom assistance to remove
the connection between the first wall socket and other wall sockets, as shown below. On an
alarm input trigger, the EDAC 400-02 takes over the telephone line, disconnecting all other calls.
The alarm condition is immediately acted on and cannot be stopped by unauthorised means.
When not triggered, the EDAC 400-02 has no effect on the phone line.
