NFS2-640/E Installation Manual —
P/N 52741:P2 7/10/14
Installation
Installing the Control Panel
• Align the keypad with the mounting holes as shown in Figure 3.6 and screw it down.
3. If installing the NCA-2 as primary display: Secure it to the NFS2-640/E chassis with
NCA/640-2-KIT as described in the
NCA-2 Manual.
4. If installing option boards, do so as described in Section 3.6, “Mounting Option Boards”. If
NFS2-640/E is being installed into an older backbox, two additional steps must be taken:
5. Battery Plate BP-4 must be replaced with BP2-4, per UL’s revised labeling requirements.
6. The older door and dress panel must be replaced with equipment compatible with KDM-R2.
†If the NFS2-640/E chassis is not assembled as when shipped, attach CPU2-640 to the chassis. Slide control-
panel tabs into slots on chassis and lay the board onto stand-offs so that mounting holes line up with those on
the chassis. Secure with six screws and four 1 inch stand-offs as shown in Figure 3.5, “Mounting KDM-R2”.
3.5.2 Using NCA-2 as Primary Display
The NFS2-640/E can be set up to use the NCA-2 as the primary display. In this system design,
mount NCA-2 to the NFS2-640/E chassis in front of CPS-24/E, and connect the network/service
port on the NFS2-640/E (J1) directly to the network/service port on the NCA-2 (J3). See the
NCA-
2 Manual
for specific instructions.
If the NFS2-640/E and NCA-2 are being used as a stand-alone pair, each device must be
programmed using VeriFire Tools. Connect the VeriFire Tools PC to NFS2-640/E using USB B
Port J3 and program as described in VeriFire Tools on-line help.
For older PCs without USB connectors, NFS2-640/E and NCA-2 must be temporarily disconnected
and separately programmed, because VeriFire Tools also uses the network/service port. Follow
VeriFire Tools instructions for off-line programming mode.
!
CAUTION:
It is critical that all mounting holes of the NFS2-640/E are secured with a screw or standoff to insure
continuity of Earth Ground.
