A short on this input generates a trouble signal.ĬPU Mainboard components Zone Coder This input is used to interface the NFS-320 to a UZC-256 Universal Zone Coder. The alarm relay will activate during microprocessor failure regardless of the settings of switches SW1-SW4.ĬPU Mainboard components System switches Onboard switches are provided for the execution of Acknowledge, Silence and Reset functions during service and maintenance when a local keyboard/display has not been installed on the CPU-320.ĬPU Mainboard components KDM Connector The KDM-R2 Keyboard Display interfaces to the CPU-320 via a ribbon cable on J7.ĬPU Mainboard components Status LEDs Onboard LEDs annunciate the status of critical system status.ĬPU Mainboard components The Aux Inputs The CPU-320 contains an input for the receipt of auxiliary trouble signals on J6. If the mainboard´s microcontroller fails and an alarm is reported by any detector or a monitor module that has backup reporting enabled, the NAC will turn on if the corresponding switch is enabled. Use 12 AWG wire (max) with a 600 – volt rating.ĬPU Mainboard components Backup Switches Backup alarm switches are provided that enable NACs to activate during a backup alarm condition. The battery charger output support 18 – 200 AH batteries.ĬPU Mainboard components TB1: AC POWER: HOT – NEUTRAL – EARTH Primary AC power source – 120 VAC, 50/60 Hz, 5.0 A from the voltage source. ĬPU Mainboard components TB3: Battery Connection The NFS-320 requires a secondary power source of 24 VDC.

System features Single Cabinet solution Quick-change CPU/Chassis Assembly One Signaling Line Circuit (SLC) Up to 318 intelligent FlashScan points Four Notification Appliance Circuits (NACs) īasic System A basic NFS-320 system is made of the following components: CPU, Power Supply & mounting chassis Cabinet Internal Dress Panel This additional equipment is used to meet specific application requirements: Serial Printer Annunciators Digital Communicator Network Card ĬPU-320 and CPU-640 The NFS-320´s CPU is identical to the CPU2-640, but with two main exceptions: The NFS-320 is not expandable beyond the one standard SLC loop provided on the motherboard. Its primary features minimize installation time, simplify maintenance and increase usability. Introduction: The NFS-320 is engineered specially for small applications.
NFS-320 Intelligent Fire Alarm System This module introduces you to features, components and operation of the NFS2-320.
