Optional Devices System OverviewNFS-640 Installation Manual P/N 51332:B1 12/01/2003 172.4 Optional DevicesSeveral optional components can be installed within the NFS-640 system. This list provides only asample of common equipment; for a complete list of what is available, refer to Appendix C“Compatible Equipment” and for a list of conventional equipment, refer to the DeviceCompatibility Chart.Network Control Annunciator - NCA. Provides a text-based, 24 VDC powered, display andcontrol device for Noti•Fire•Net. It incorporates a large LCD display and a silicone-rubberQWERTY keypad. It will display all events from a Noti•Fire•Net system.Network Control Module - NCM-W/F. The NCM is an interface between the panel andNoti•Fire•Net. It comes in two models: wire and fiber-optic cable. Refer to the NCM-W/FInstallation Document for more information and installation instructions.Loop Expander Module - LEM-320. The LEM plugs into the control panel, expanding theboard’s function to control two Signaling Line Circuits (SLCs). Each NFS-640 can have one LEM.Refer to Section 3.5 “Installing the Control Panel” for installation instructions.Auxiliary Power Supply - APS-6R. The optional Auxiliary Power Supply is a 150W cabinet-mounted power supply, designed to power devices that require filtered, non-resettable power, suchas XP Transponder modules, NAC modules, and addressable Notifier appliance circuit modules.The APS-6R provides three 24 VDC output circuits (6 A total in alarm, 4 A continuous): twopower-limited circuits (3 A each) and one non-power-limited circuit (6 A). Refer to the APS-6RInstruction Manual for further information and installation instructions.Addressable Charger/Power Supply - ACPS-2406. The optional ACPS-2406 is anaddressable loop-based power supply and battery charger. This cabinet-mounted unit provides fourindividually addressable Notification Appliance Circuits. In addition, each circuit can providenotification appliance synchronization without an additional module. The unit charges 7 to 25 AHbatteries with full supervision. The ACPS-2406 provides up to four 24 VDC (filtered) outputcircuits (2.5 A max each, 5.0 A total continuous, 6.0 A during a fire alarm). Refer to the ACPS-2406 Instruction Manual for further information, installation instructions, and battery calculations.Batteries and Battery Boxes. The control panel uses only sealed lead-acid batteries forstandby power. Maximum battery capacity is 55 AH (ampere-hour). Minimum battery capacitydepends upon your system configuration; absolute minimum is 12 AH. CAB-4 Series backboxesprovide space for two 25 AH (or smaller) batteries. Use external battery boxes if your installationrequires larger capacity batteries. Battery boxes mount directly below the main cabinet. Battery boxmodel NFS-LBB holds batteries up to 55 AH. Refer to Section 4.2 “NFPA 72-1999 Central orRemote Station Fire Alarm System (Protected Premises Unit)” and Section A.3 “Calculating theBattery Requirements” for further information. See Battery/Peripherals Enclosure document forbackbox measurements and installation instructions.Universal Digital Alarm Communicator/Transmitter (UDACT). Transmits system status toUL-listed Central Station Receivers over a public switched telephone network. Mounting is in aCAB-4 Series backbox or remotely in the ABS-8R enclosure. The unit connects to the EIA-485annunciator port and 24 VDC (nominal) power. Refer to the UDACT Instruction Manual for furtherinformation and installation instructions.Transmitter Module - TM-4. The TM-4 includes three reverse polarity outputs and a FireMunicipal Box Trip in a single module. It provides a means for the FACP to control Alarm,Trouble, and Supervisory reverse polarity outputs (15mA, 24 VDC nominal) or a Fire MunicipalBox Trip output. All output circuits are supervised. The Transmitter Module communicates overthe standard EIA-485 connection like an ACS device and mounts easily in standard modulelocations within the cabinet or external boxes. Refer to the Transmitter Module TM-4 installationdocument for further information and installation instructions.Universal Zone Coder - UZC-256. A circuit board, used for NAC coding applications, thatprovides three NAC output circuits and up to 256 zone codes. Refer to the UZC-256 Universal
