When using an STR™ Modular Button assembly, the system can
read which switch is being pressed by electronics built into the
switches.
In the case of a Custom Panel, these electronics are built into the
TT33-2 and you must run wires to assign each button to a position
in a matrix.

The chart to the left shows an example of how a 15 button

As long as each button is connected to a unique combination

of one letter and one number then the system will be able to

assign addresses to each button.

Using the matrix on the TT33-2 module, you can get 4x6 (24)

unique combinations. One of these combinations (DL) can be
4
used for special functions, so you can have up to a total of 23
5
or 24 apartments using the TT33-2 alone. If your system has
6
more apartments you may add the following parts (one for
1
each entry) which will extend the matrix by giving you more
2
numeric connections. Please refer to the chart below.
