NFS2-640/E Installation Manual —
P/N 52741:P2 7/10/14
System Overview
System Components
2.1.2 Options
Refer to Section 2.4 “Compatible Equipment” for other peripherals listed for use with this panel.
•
QWERTY silicone-rubber keypad with a 2x40 LCD display and eight indicator LEDs
•
Optional LEM-320 provides a second SLC loop that is electrically identical to the one on the
main board
•
Optional devices include: UDACT/UDACT-2 Universal Digital Alarm
Communicator/Transmitter, ACM-8R remote relay module to increase point capacity, and
audio and voice components.
•
Optional annunciators connected through the EIA-485 interface allow remote system
monitoring.
2.1.3 System Limitations
System expansion must take into consideration the following:
1. The physical limitations of the cabinet configuration.
2. The electrical limitations of the system power supply.
3. The capacity of the secondary power source (standby batteries). (Note that batteries larger than
26 AH will require a separate battery backbox.)
2.2 System Components
2.2.1 Basic Equipment
A basic NFS2-640/E system has the following components:
1. The control panel with integral power supply. CPU2-640 (120V operation) or CPU2-640E
(240V operation) is the “control panel” itself and the heart of the system; it ships with a
grounding cable, battery interconnect cables, and document kit. It includes power supply CPS-
24/E, mounted directly on the CPU2-640/E.
NOTE:
The CPS-24/E is an integral part of the
CPU2-640/E
and is not available separately.
2. One or more chassis. The NFS2-640/E chassis (included with the CPU) mounts the CPU2-
640/CPU2-640E and peripherals. Mount additional rows of equipment in a compatible chassis
selected from Table 3.3 on page 24.
3.
Optional:
A primary display. Generally this is a KDM-R2 keypad/display behind a DP-DISP2
or ADP2-640 dress panel. For information on using NCA-2 as primary display instead of
KDM-R2, see Section 3.5.2 “Using NCA-2 as Primary Display” and the
NCA-2 Manual
.
4. A backbox and door:
SBB-A4 and DR-A4 (one row of equipment) or
SBB-B4 and DR-B4 (two rows of equipment) or
SBB-C4 and DR-C4 (three rows of equipment) or
SBB-D4 and DR-D4 (four rows of equipment)
(For a solid-metal door add “B” to the part number; for a red door add “R”.)
5. A battery dress panel BP2-4 is required.
6. Batteries (Refer to Appendix A.3 “Calculating the Battery Requirements” for system current-
draw calculations; CAB-4 series backboxes holds batteries up to 26 AH maximum.)
Refer to Section 2.4, “Compatible Equipment” for other peripherals listed for use with this FACP.
