4.3 Operation from a Local Telephone
While this is not the normal method of operation, it is possible to connect to the DAI-2 from a local telephone located
near the DAI-2. A local connection is typically used only for initial programming or testing. A local connection
bypasses the security codes. This can be particularly helpful if you change one or more codes are forget them.
4.3.1 Connect Button
The following procedure uses the Connect button located on the rear panel of the DAI-2. This button works as either
a momentary or maintained contact depending on how you use it. If the button is pressed briefly and released, the
DAI-2 will connect to the telephone line and wait for a non-alterable attention signal of ❊❊❊❊. After the attention
signal is given, the unit will enter the operating mode and remain there until you hang up the telephone.

If the button is pressed and held, the DAI-2 will wait for the attention signal and enter the operating mode as above. It
will remain in the operating mode as long as the Manual Connect button is held. The connection will be broken when
the button is released for three seconds.
The Manual Connect button is disabled when the DAI-2 is online with a telephone call.
When a connection is made using the Connect button, the DAI-2 does not enforce the programming security code for
10 seconds. This should give you enough time to enter the programming mode in the event that you need to
reprogram any security codes that have been lost. If the DAI-2 is still in operating mode after 10 seconds, it will
enforce the programming security code as usual.
4.3.2 Manual Connection with Telephone Lines
The easiest way to establish a manual connection to the DAI-2 is to use two telephone lines. Designate one line as
the calling line and the other as the receiving line. Connect the DAI-2 to the receiving line and call it from the calling
line. Press the Connect button when you hear the line ringing. This will force the DAI-2 to seize the line and place it in
the operating mode as if the security codes were successfully entered. The DAI-2 will confirm that it is in the
operating mode with two short tones to signal that it is waiting for commands.
It is important to press the button before the DAI-2 answers the line. If the DAI-2 answers first, you will hear one long
tone instead of two short beeps. The long tone indicates that the DAI-2 is expecting a security code.
Operate the unit as you would normally, making any changes you need to the system programming. When you are
finished, hang up the originating telephone. The DAI-2 will hang up automatically.
If you have only one telephone line but you have a cellular telephone, substitute the cell phone for the calling line and
call the DAI-2 as described previously.
