NCM-1 Datasheet, PDF (1/1 Pages) Gamewell-FCI by Honeywell – Noise Control Module

NCM-1
Description
The Gamewell-FCI, NCM-1 Noise Control Module
(patented) is used to reduce the common noise (for
example, noise that is present on both conductors)
on the Signaling Line Circuit (SLC). The NCM-1
allows the use of untwisted, unshielded wire on the
SLC. Applications that have audio or fire fighters’
telephones require the use of twisted/shielded wiring
for all circuits including the SLC. The NCM-1 may
also be used in these applications to further reduce
the common mode noise.
Installation
To wire the NCM-1, connect it directly in line with the
SLC Loop. To connect the SLC circuit, the NCM-1
includes a pig-tail lead. To determine the maximum
wiring distance, refer to Table 1. All distances are
rated a maximum allowable distance and AWG wire.
Note: For systems without shield, cut the white wire.
Specifications
Table 1 lists the SLC wiring specifications that do not
include audio for the following Systems.
• E3 Series (Expandable Emergency Evacuation) System
• S3 Series (Small Addressable FACP) System
• 7100 Series System
