System Components
System Overview
2.1.2 Options
Refer to Section 2.2 “System Components” for descriptions of the various optional modules.
•
Optional devices include: Wire and Fiber
versions of the NCM or HS-NCM
connection to the Noti•Fire•Net and High-
Speed Noti•Fire•Net, UDACT/UDACT-2
Universal Digital Alarm
Communicator/Transmitter, and ACM-8R
remote relay module to increase point
capacity.
•
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 Standard Equipment
The standard, factory-assembled NFS-320/E/C system includes the following components:
•
The control panel with integral power supply, and cabinet. NFS-320 (120V operation) or NFS-
320E (220-240V operation), and CPS-24/E. NFS-320/E is the “control panel” itself and the
heart of the system; it ships with a grounding cable, battery interconnect cables, and document
kit. CPS-24/E mounts directly on the control panel. The system ships pre-installed in its
cabinet.
NOTE:
The CPS-24/E is an integral part of the
NFS-320
and is not available separately.
•
A primary display KDM-R2 keypad/display.
Batteries are ordered separately; refer to Appendix A.3 “Calculating the Battery Requirements” for
system current-draw calculations.
Up to two option boards can be installed within the FACP’s cabinet; additional optional peripherals
can be mounted in auxiliary backboxes. Refer to Section 2.3, “Compatible Equipment” for
equipment listed for use with this FACP.
2.2.2 Control Panel Circuit Board
The control panel electronics are contained in NFS-320 and its built-in power supply. The printed
circuit board incorporates a signaling line circuit (SLC) and the central processing unit; the power
supply has an integral battery charger. A keypad/display unit is installed over the power supply as
shown Figure 2.1. Wiring is shown in Figure 2.2, “NFS-320 and Power-Supply: Wiring
Connections” and Figure 2.3, “NFS-320 and Power-Supply: Jumpers, LEDs and Switches”.
