status (DS7432E)

The DS7432 Series Eight-input Remote Modules
include the DS7432, the DS7432-CHI, and the
DS7432E. All modules address up to eight input loops
of conventional contacts to the multiplex bus of the
control panel. The DS7432E has an additional serial
dual end-of-line (EOL) wiring configuration. The
DS7432E addresses up to sixteen input contacts
(alarm and tamper for each loop).The DS7432 and
DS7432-CHI each use one 47 kΩ resistor per input.
The DS7432E uses 22 kΩ + 47 kΩ per input.
