Chapter 3 – Installation Field Wiring
Installation Overview
Induced noise can interfere with telephone communications. To minimize the potential for induced noise
follow these wiring precautions:
Isolate input wiring from output and power wiring.
Do not use a common conduit for input, output, or power wiring. If they must be run together,
use shielded cable for as short a distance as possible and ground the shield at the panel only.
Route all wiring around the inside perimeter of the enclosure. Do not cross the PC board.
Selecting a Location
The Keltron S/FDACT may be installed in any environment which would be comfortable for a human
being. Typically, the S/FDACT will be installed in the same room as the FACP which it is monitoring.
Please read the environmental specifications for details. In addition:
Do not mount on exterior walls, especially masonry walls
Do not mount directly on exterior walls below grade
Protect from splashing water
Protect from water leaks
Do not mount in areas of high humidity
Wall Mounting
Mount the S/FDACT enclosure securely to a
plywood panel or interior wall. The
enclosure provides four keyhole shaped
mounting holes. If necessary, pre-drill holes
separated by 14.75 inches horizontally, and
11.76 inches vertically.
