Dual Input Waterflow, Supervisory Module
E-IDCWS
contact initiating devices. When the NO input contact of an
initiating device is closed, a supervisory signal is sent to the
control panel and the supervisory condition is not latched at
the module.
Latching: Configures the module for normally open dry contact
initiating devices. When the NO input contact of an initiating
device is closed, a supervisory signal is sent to the control pan-
el and the supervisory condition is not latched at the module.
•
The E-IDCWS connects normally open waterflow alarm and supervi-
sory initiating device circuits (IDCs) to the Edwards Signaling control
panel. The E-IDCWS 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 second address is automatically assigned one number higher
that the value set on the rotary switches.
The E-IDCWS can operate in the following modes:
Waterflow
Alarm latching delayed: Configures the module for use with
only nonretarded waterflow alarm switches. When the NO
input contact of an initiating device is closed, an alarm is sent
to the control panel, which after a 16 second time delay, gener-
ates an alarm signal.

SLC Fault Isolator Module
E-ISO
The E-ISO protects a Class A SLC from total collapse due to wire-to-
wire short circuits. The module monitors line voltages and opens the
SLC when a short is detected. A short is isolated between the two
modules located electrically closest to the short.
The device address is set using the two rotary switches located on
the front of the module. One device address is required.
