Class A Single Input Module
E-IDC1A
The Class A Single Input Module is used to connect a normally open,
alarm, supervisory, or monitor type dry contact initiating device
circuit (IDC) to the Edwards Signaling control panel. The module is
designed for Class A circuit operation.
The module's device address is set using the two rotary switches
located on the front of the module. One device address is required.
The device can be preset for alarm or supervisory operation using
the slide switch located on the front of the module. The module
can also be configured for other device types through front panel
programming or the configuration utility.
