E-IDC2B Analog Dual Input Module Installation Sheet
Operation
The module is an analog addressable device used to connect
two normally open, alarm, supervisory, or monitor type dry
contact 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 automat ica lly
assigned one number higher that the value set on the rotary
switches.
The device can be preset for alarm or supervisory operation
using the slide switch located on the front of the module. The
module can also be configured for other device types through
front panel programming or the configuration utility.
Slide switch operation
The following slide switch settings determine the operation of
the module. Setting the initial slide switch position is generally
performed during module installation. This setting can be
changed while the system is operating, but the change must be
confirmed through front panel programming.
Slide switch P1 is used for IDC 1 and slide switch P2 is used
for IDC 2. The waterflow device type available through front
panel programming or the configuration utility can only be used
with slide switch P1.

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 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
