The E-IDCWS connects normally open waterflow alarm and supervisory initiating device circuits (IDCs) to the Edwards control panel. The EIDCWS is designed for Class B circuit operation. The device address is set using the two rotary switches located on the front of the module. Two consecutive addresses are required. The first input address is fixed as waterflow and the second address is fixed as supervisory. The second address is automatically assigned one number higher that the value set on the rotary switches. The E-IDCWS includes a dual color LED, green to indicate normal polling and red to show when the device is active.
