PROGRAMMING
General
NOTE: The V-2901A can be accessed via
tone dial systems and programming must be
performed with a tone dial set.
The V-2901A is designed to allow the user to
program its functions to meet the requirements of the
specific application. The V-2901A is; however,
shipped from the factory with the all functions pre-set
to default settings. These default settings are listed in
the Program Chart.
It is strongly recommended that the default
settings be changed to suit the needs of the
situation. The settings of the Access Code and
Door Unlock Code, particularly, should be
changed to provide a more secure system.
The following instructions explain the procedures to
program the codes for the V-2901A. Individual
codes can be programmed per feature. After each
program change, a dial tone will be received
designating a proper entry.
Master Access Code
The Master Access Code allows entry to
programming as well as to the use of the system. It is
essential that this code remain confidential to
maintain the security of the system. The Access
Code can be 1 to 7 digits in length. The asterisk (*)
or number (#) signs can not be used in the access
code.
The default master access code is 1 2 3. To change
this code:
1. Lift handset, press # and hear dial tone.
2. Press # # # on the dialpad.

Programming Functions
The following program instructions show the
access code for each function as 1 2 3. If a new
master access code is programmed prior to
programming the following functions, the new
access code would be substituted where the 1 2 3 is
shown.
These following codes cannot contain # as part of
their code.
