3.1 Installation Steps and Precautions
Begin by disconnecting all power sources to avoid electrical hazards. Carefully unpack and inventory all components. Mount the control panel securely‚ ensuring proper ventilation. Next‚ connect the batteries using the provided interconnect cables (P/N 75560 and 75561). Proceed to wire the system‚ adhering to UL requirements for power-limited and non-power-limited circuits. Refer to the NFS-320 Installation Manual for specific wiring diagrams and guidelines. After wiring‚ power on the system and perform a self-test to verify functionality. Use VeriFire Tools to program the control panel‚ ensuring all settings meet local fire safety codes. Finally‚ conduct a thorough system test‚ including smoke and heat detector sensitivity checks‚ to ensure reliable operation. Always follow manufacturer instructions to guarantee a safe and compliant installation.
3.2 Initial Configuration and Wiring
Start by connecting the control panel to the desired power source‚ ensuring all wiring meets local electrical codes. Carefully wire smoke and heat detectors‚ manual pull stations‚ and audible devices‚ following the layout specified in the NFS-320 Installation Manual. For networked systems‚ connect the EIA-232 port to a PC or remote terminal for monitoring and programming. Use VeriFire Tools to configure the system‚ setting up zones and ensuring proper communication between components. After wiring‚ perform a power-up self-test to verify all devices are recognized. Address any issues promptly to ensure system reliability. Proper configuration and wiring are critical for maintaining fire safety and compliance with regulations.
Programming the NFS-320 System
Program the NFS-320 using the keypad or VeriFire Tools for advanced functions. Define zones‚ set sensitivity levels‚ and configure special functions like Presignal and PAS. Ensure all settings are tested thoroughly for optimal performance.
4.1 Using the Keypad for Basic Programming
The NFS-320 keypad serves as the primary interface for basic programming tasks. Use it to navigate menus‚ define zones‚ and configure system settings. Start by entering the programming mode using the appropriate key sequence. Once access is granted‚ you can adjust zone settings‚ such as assigning zone types (e.g.‚ smoke‚ heat‚ or manual pull stations) and enabling or disabling specific features. The keypad also allows you to set sensitivity levels for detectors and configure time delays for functions like Presignal or Positive Alarm Sequence (PAS). For each change‚ ensure you follow the correct sequence of key presses to save the configuration. Testing each setting is crucial to confirm proper operation. While advanced features may require VeriFire Tools‚ the keypad provides efficient control for essential programming needs‚ ensuring your system operates as intended.
4.2 Advanced Programming Functions
Advanced programming functions on the NFS-320 enable customization beyond basic settings‚ allowing for tailored system behavior. These include configuring Special Zones‚ Releasing Functions‚ and network integration. Special Zones can be programmed to trigger specific responses‚ such as activating strobe lights or voice messages during alarms. Releasing Functions allow for controlled deactivation of systems‚ such as releasing clean agents or shutting down HVAC systems. For networked systems‚ advanced functions include syncing multiple panels and enabling remote monitoring. The keypad supports these configurations‚ but complex setups may require VeriFire Tools for precision. Additionally‚ advanced features like Presignal and Positive Alarm Sequence (PAS) can be fine-tuned to meet specific site requirements. Ensure all changes are thoroughly tested to maintain system reliability and compliance with safety standards. Always refer to the manual for detailed instructions to avoid errors during implementation.
Advanced Features and Customization
The NFS-320 offers advanced features like Special Zones‚ Releasing Functions‚ and network integration for tailored system behavior. Customization options include Presignal‚ Positive Alarm Sequence (PAS)‚ and remote monitoring capabilities.
5.1 Special Zones and Releasing Functions
Special Zones on the NFS-320 allow for customized alarm responses‚ enabling specific actions during an emergency. Releasing Functions‚ such as Clean Agent Release or Pre-Discharge Notification‚ can be programmed to trigger at defined stages. These features ensure tailored system behavior‚ enhancing safety and operational efficiency. The Presignal function delays alarm activation‚ allowing investigation before full alert‚ while Positive Alarm Sequence (PAS) requires confirmation from multiple detectors to reduce false alarms. Both functions are configurable via the keypad or VeriFire Tools software. Special Zones can also integrate with optional modules‚ such as the ACM Series annunciator‚ for expanded monitoring.
