The E-IDC1B connects a normally open, alarm, supervisory, or monitor type dry contact initiating device circuit (IDC) to the Edwards control panel. This module is for Class B circuit operation. The
device address is set using the two rotary switches located on the front of the module. One device address is required. The module is configured to operate as an alarm latching device type from the factory. When the NO contact of an initiating device is closed, an alarm signal is sent to the control panel and the alarm condition is latched at the module. Additional device types are available through front panel programming or the configuration utility. Refer to applicable control panel technical reference manual. The E-IDC1B includes two LEDs, green to indicate normal polling and red to show when the device is active.
