2․2 Status Indicators and LEDs
The NFS-320 control panel uses a variety of status indicators and LEDs to monitor system activity; The Power LED is green when the system is operational․ The Fire Alarm LED flashes red during an alarm and turns steady once acknowledged․ System Trouble and Supervisory LEDs are yellow, flashing during issues and steady after acknowledgment; The Signals Silenced LED illuminates yellow when audible alerts are muted․ Additional LEDs include Pre-Discharge, Discharge, and Abort Active, providing real-time status updates for fire suppression systems․ These indicators ensure quick identification of system conditions, enabling prompt responses to alarms or troubles․
Normal Operating Modes
The NFS-320 operates in standby mode when idle, indicated by a steady green POWER LED․ The system is ready to detect alarms and supervisory conditions, ensuring timely responses․
3․1 Standby Operation and System Ready States
In standby mode, the NFS-320 is fully operational, monitoring all connected devices․ The green POWER LED remains lit, indicating proper system function․ Red FIRE ALARM and yellow TROUBLE LEDs are off, signifying no active alarms or issues․ The system is ready to respond to events, ensuring safety and reliability․ This state is crucial for continuous protection, allowing immediate detection of any abnormalities․ Regular checks ensure the system remains in optimal condition, adhering to safety standards and providing consistent monitoring capabilities․
3․2 Monitoring and System Status Displays
The NFS-320 continuously monitors system status, displaying real-time information via LEDs and the LCD․ The FIRE ALARM LED flashes during alarms, while the PRE-ALARM LED indicates threshold alerts․ The SECURITY LED illuminates for security breaches, and the SUPERVISORY LED flashes for system checks․ The LCD shows detailed status messages, such as active alarms or supervisory conditions․ Users can navigate through messages using the ACKNOWLEDGE/SCROLL DISPLAY key, ensuring clear visibility of all system events․ This comprehensive monitoring ensures immediate awareness of system states, enabling prompt responses to any situation․
Alarm and Trouble Conditions
The NFS-320 detects alarm and trouble conditions, alerting users via LEDs and LCD messages․ Alarms trigger audible signals, while troubles indicate system issues requiring immediate attention․
4․1 Responding to Alarms and Acknowledging Signals
When an alarm occurs, the NFS-320 activates audible signals and illuminates the red FIRE ALARM LED․ Users must press the ACKNOWLEDGE/SCROLL DISPLAY key to silence the piezo sounder and stop flashing indicators․ This action sends an acknowledgment message to the printer and history file․ The system also automatically silences sounders on connected FDU-80 and ACS annunciators․ Acknowledgment ensures awareness of the alarm condition, allowing for investigation and resolution․ The FIRE ALARM LED remains steady until the alarm is cleared and the system is reset, ensuring all issues are addressed promptly and efficiently․
4․2 Managing Trouble Conditions and Supervisory Alerts
When a trouble condition occurs, the yellow TROUBLE LED flashes, and the LCD displays specific fault messages․ Pressing the ACKNOWLEDGE/SCROLL DISPLAY key silences the piezo sounder and changes flashing indicators to steady․ The LED remains lit until the issue is resolved․ Supervisory alerts, such as sprinkler valve tamper conditions, also trigger the yellow SUPERVISORY LED․ These alerts require immediate attention and are indicated on the LCD․ Contact a local service representative for assistance․ Hazard Alerts or Tamper conditions latch until manually reset, ensuring persistent notification of unresolved issues․ Prompt action ensures system reliability and compliance with safety standards․
System Control and Advanced Features
This section explores advanced system control functions, including Drill Mode, Signal Silence, and System Reset, designed to enhance operational flexibility and ensure system readiness for various scenarios․
5․1 Drill Mode and Signal Silence Functions
Drill Mode allows testing of alarm systems without triggering actual alerts․ It activates silenceable circuits and disables audible signals temporarily․ Signal Silence function mutes alarms during drills or emergencies, ensuring minimal disruption while maintaining system awareness․ Both features enhance operational control, enabling users to manage situations effectively while adhering to safety protocols․ These functions are crucial for system maintenance and emergency preparedness, providing flexibility in handling various scenarios․ Proper use of these features ensures efficient management of fire alarm operations, maintaining safety and reducing unnecessary disturbances․
5․2 System Reset and Lamp Test Operations
The System Reset function restores the NFS-320 control panel to its default operational state, clearing all active alarms and system states․ This function is typically used after addressing an alarm condition or during maintenance․ The Lamp Test operation checks the functionality of all LEDs and indicators on the control panel, ensuring proper system status visibility․ Pressing and holding the reset switch activates the lamp test, illuminating all LEDs to verify their operation․ These operations are essential for system reliability, allowing users to confirm panel functionality and prepare for normal operation․ Regular testing ensures compliance with safety standards and maintenance requirements․
