E-IDCWS Analog Dual Input Waterflow/
Supervisory Module Installation Sheet
Operation
The module is an analog addressable device used to connect
normally open waterflow alarm and supervisory initiating
device circuits (IDCs) to a control panel. This module 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 device addresses
are required. The second device address is automatically
assigned one number higher that the value set on the rotary
switches.
The module can operate in the following modes:
Table 1: Module operation
Operation
Device type description
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, generates an alarm signal.
Supervisory
Supervisory active nonlatching US marketplace
Supervisory active latching Canadian marketplace
Nonlatching: 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 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 panel and the supervisory condition
is not latched at the module.
LED operation
The module provides a bicolor LED that shows its status.
Normal: Green LED flashes
Alarm/active: Red LED flashes
Installation
WARNINGS
• This module will not operate without electrical power. As
fires frequently cause power interruption, you should
discuss further safeguards with your local fire protection
specialist.
• This module does not support conventional smoke
detectors.
Note: The module is shipped from the factory as an assembled
unit; it contains no user-serviceable parts and should not be
disassembled.
To install the module:
1. Verify that all field wiring is free of opens, shorts, and
ground faults.
2. Make all wiring connections as shown in “Wiring.”
3. Set the module address as follows:
Use a screwdriver to adjust the two rotary switches on the
front of the module. Set the TENS rotary switch (0 through
12) for the 10s and 100s digit and the ONES rotary switch
for the 0 through 9 digit. For example: device address 21,
set TENS rotary switch to 2 and set the ONES rotary
switch to 1.
Refer to “Specifications” for available address numbers.
4 Mount the module on the electrical box using screws
provided with the electrical box.
5. Mount the wall plate on the module using #4-24 x 1/2 in.
(13 mm) self-tapping screws.
