Single Input Mini Module
E-IDC1B
The E-IDC1B connects a nor-
mally open, alarm, supervisory,
or monitor type dry contact
initiating device circuit (IDC) to
the Edwards Signaling 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 initi-
ating 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 configura-
tion utility. Refer to applicable
control panel technical refer-
ence manual.
