DZ209/5 / DZ209/10
Diode Board Units
The Alpha®/S.T.R.™ DZ209/5 and DZ209/10 diode
board units are designed to work with our HT2009 or
HT3009 (2-wire) apartment handset stations and/or
5661/000 (NoCoax) type video-intercom systems.
The DZ209/5 diode boards are installed into the lobby
entry door stations, to enable standard pushbuttons to
be used with the HT2009, HT3009 and 5661/000
systems. The diode boards are provided with self-stick
tape to allow them to be mounted in a convenient spot,
inside the lobby entry panel(s).
The diode boards allow the pushbutton selective wires
to also act as common wires, when the pushbuttons
are not being depressed.
The DZ209/5 has 5 diodes and the DZ209/10 has 10
diodes, to allow them to work with 5 buttons and 10
buttons, respectively. They can be mixed and matched
in a panel, depending upon the total number of buttons.
For example, for a 35 button panel, you would use 3-
DZ209/10 boards and 1- DZ209/5 board.
