NOTICE TO THE INSTALLER
This manual provides an overview and the installation instructions for the IDC-6 module.
All terminals are power limited and should be wired in accordance with the requirements of NFPA 70 (NEC) and NFPA
72 (National Fire Alarm Code). Failure to follow the wiring diagrams in the following pages will cause the system to not
operate as intended. For further information, refer to the control panel installation instructions.
The module shall only be installed with listed control panels. Refer to the control panel installation manual for proper
system operation.
1. DESCRIPTION
The Initiating Device Circuit Expander (IDC-6) provides an additional 6 inputs per module. The panel supports up to
thirty-one (31) IDC-6 modules. The circuits are power-limited and supervised. All inputs are suitable to monitor 2-wire
smoke detectors. Smoke detectors shall be installed in compliance with NFPA 72. Inputs can also be used for automatic,
manual, waterflow or supervisory service. The IDC-6 communicates via the PLink communication bus. The IDC-6 can be
mounted in either the control panel cabinet, the intelligent power supply, AE-2, AE-8 or the AE-14 expander cabinet. Each
card is mounted to the exclusive Stacker Bracket for secure and accessible mounting.
2. SETTING THE ADDRESS
Each P-Link device has a
five (5) position dip switch
which is used to program the device address ranging from one (1)
to thirty-one (31). The table below may be used to set dip switches when addressing any P-Link module:

–
31)
Note:
Each
"gray" box
indicates that the dip switch is
"On,"
and each
"white" box
indicates
"Off."
The examples shown below illustrate a P-Link's dip switch settings: the 1st example shows a P-Link module
not ad-

where all dip switch settings are in the
default
"Off" position
, the 2nd illustrates an
addressed P-Link module
via
the dip switch settings.
