Description
This document includes installation information for the
IU2080NC Indicating Circuit Controller. The module provides a
supervised output for audible and visual notification devices
and is designed for use with FP1200C-2000C and 2X Series
addressable fire systems.
The module is powered by an auxiliary 24 V power supply and
can provide an output current of up to 2.04 A. The external
power supply is monitored for low voltage and the external fault
relay for open circuit.
Caution:
An EN 54-4 approved external power supply must be
used. For safety, always power only one IU2080NC module
from a single power supply.
With the end-of-line resistor installed, the module monitors the
notification circuit for short circuit and open circuit.

Installation
Caution:
For general guidelines on system planning, design,
installation, commissioning, use, and maintenance, refer to the
EN 54-14 standard and local regulations.
Assembly
Install the module into the protective housing as shown in
Figure 1. Connecting cables should be fed through the cable
entry hole at the rear of the protective housing before the
module is fixed into place.
Addressing
Each module must be assigned an address from 1 to 128. Use
the rotary dial marked 0 to 12 to set the tens and hundreds part
of the address, and the rotary dial marked 0 to 9 for the
remaining digits. See Figure 4 for example address settings.
Note:
To overcome the mechanical effects of shipping and
storage we recommend that you first rotate each dial counter-
clockwise (to the 0 position) and then clockwise (to the dial's
maximum position) before setting the required address.
To change the address of a module that is operational:
1.
Disconnect the module from the loop.
2.
Change the address on the module using the rotary dials.
3.
Connect the module to the loop.
4.
Configure the device at its new address, and then remove
the old device address at the panel.
Wiring
Wire the module as shown in Figure 3.
Caution:
To overcome contact resistance and ensure reliable
operation, a minimum load of 100 mA is required for the
notification output (if the load is less than 100 mA, install a
resistor in series with the diode to make up the difference).
Observe polarity on loop and output connections.
