Description
This document includes installation information for the
IU2055NC Conventional Zone Monitor Unit. The IU2055NC
provides an interface between conventional detection devices
and compatible addressable fire control panels.
The module supervises the conventional zone for open circuits,
short circuits, device faults, and alarm conditions.
The module enables the addressable panel to monitor the
presence and operation of:
• Up to 30 compatible conventional detectors in standard
installations
– or –
• Up to 20 compatible intrinsically safe (IS) conventional
detectors in intrinsically safe installations
Caution: Only use compatible devices as specified in the
IU2055NC Compatibility List (available at
firesecurityproducts.com).

Installation
Caution:
For general guidelines on system planning, design, installation,
commissioning, use, and maintenance, refer to the EN 54-14
standard and local regulations.
See your control panel compatibility list for details of devices
that can be used in fire system applications that require
EN 54-13 compliance.
Before installation
Conventional zone monitoring units add a significant load to
the addressable detection loop.
Always use the System Builder loop calculation software to
validate the predicted loop load before installation. If the
number of modules required in your installation requires a
higher load than is available, consider adding conventional fire
panels to your addressable network to avoid overloading the
detection loop.
Caution: To ensure correct operation, the device operating
voltage must be in the range 21 to 28 VDC.
Guidelines for intrinsically
The module must be installed immediately outside the
intrinsically safe (Ex-classified) area and as close to the
GBX2000 barrier as possible when used in an intrinsically safe
system.
The module must be configured for intrinsically safe operation
(see "Configuration").
