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

Device type description

Alarm latching delayed: Configures the module for use
with only nonretarded waterflow alarm switches. When

alarm is sent to the control panel, which after a 16
second time delay, generates an alarm signal.

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

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.

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 “Specification s” for availa ble addr e ss number s.

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 screw s.
