FX-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 than 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
Install and wire this device in accordance with applicable national and
local codes, ordinances, and regulations.
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” and Figure 3.
3. Set the module address. Refer to the panel technical reference
manual for a list of valid addresses.
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 (see Figure 1).
4. Mount the module on the electrical box using screws provided with
the electrical box.
5. Mount the wall plate on the module using the hardware shown in
Figure 2.
