Installation
Laying Out Equipment in Cabinet and Chassis
The CPU mounts in the NFS2-640 chassis behind DP-DISP2 (top row) or ADP2-640 (lower row).
The control panel fills three positions in the first-installed layer against the chassis; its power
supply occupies two positions on top of the control panel; and the optional display occupies two
positions in the fourth layer (flush with the dress panel).
Mount second, third, or fourth rows of equipment in other compatible chassis, such as chassis CHS-
4L, CA-1, or CA-2. (See Table 3.3, “Chassis Compatibility,” on page 24.) For details on audio
equipment see the
DVC Manual
.
Option boards use standard mounting hole positions to allow them to be mounted in various
locations and layers, depending on the desired system configuration. (See Table 3.2 to determine
hardware.) Some equipment such as annunciators may be mounted on a dress panel directly in front
of the control panel. The BMP-1 Blank Module Plate covers unused positions in a dress-panel, also
providing an additional mounting location for some option boards, such as TM-4 (see
BMP-1
Product Installation Drawing
for details).
Annunciators can be mounted in dress panels such as ADP-4B; one or two annunciators can be
installed in the DP-DISP2 or ADP2-640 with the control panel. Installing the BMP-1 blank plate in
these dress panels provides an additional mounting location for option boards. Refer to the
equipment’s documentation for details.
Install BP2-4 Battery Plate in front of the battery compartment in NFS2-640/E installations and
provides Protected Premises Unit labels.
If DP-DISP2 is not being used in the top row of the backbox, install VP-2B above the first row to
cover the remaining space.
NOTE:
The BP2-4 is required for NFS2-640/E installations due to UL’s revised labeling
requirements. If using NFS2-640/E in retrofits, order BP2-4 to replace previous BP-4 battery dress
panels.
