Disable Alarms (DA)
Most D1000 modules feature LO/DO0 and HI/DO1 pins on the module
connector. These pins serve a dual function and can be used to output either
the alarm outputs or digital outputs 0 and 1. The Disable Alarms command
is used to connect the digital outputs 0 and 1 to the connector pins. The alarm
settings are not affected in any way except that the alarm outputs are
disconnected from the module connector. The alarm status can still be read
with the Digital Input (DI) command. The complement to the DA command
is the Enable Alarms (EA) command.
