These diagrams detail the connections for initiating devices (smoke detectors, pull stations), notification appliances (horns, strobes), and communication circuits. Always refer to the latest revision of the wiring diagrams provided with the panel.
Fire Lite employs standardized wiring color codes: red for power, yellow for initiating circuits, and white for neutral. Consistent adherence to these conventions minimizes errors and simplifies maintenance. Utilize appropriately sized wiring, conforming to local electrical codes, to ensure reliable signal transmission.
Pay close attention to end-of-line resistor values and wiring polarity. Incorrect wiring can cause false alarms or system failures. Properly label all wires at both ends for easy identification during future servicing or modifications. A neat and organized wiring scheme enhances system reliability and simplifies troubleshooting.
Device Circuit Supervision
The Fire Lite MS-4 panel continuously supervises all device circuits for opens, shorts, and grounds. This crucial feature ensures immediate notification of any compromise to the system’s integrity; Supervision utilizes end-of-line (EOL) resistors, monitoring the circuit resistance to detect faults.
A missing or incorrect EOL resistor triggers a trouble alarm, indicating a potential wiring issue or device failure. The panel’s trouble indicators pinpoint the affected circuit, facilitating rapid diagnosis. Regular testing of device circuits is vital to confirm proper supervision functionality.
Tamper switches on devices, where applicable, are also supervised, alerting to unauthorized access or removal. Proper wiring and resistor selection, as detailed in the wiring diagrams, are paramount for reliable supervision. Addressing any supervision trouble immediately is critical for maintaining a fully operational fire alarm system.
Programming and Configuration
The MS-4 panel offers flexible programming via its keypad, allowing customization of zone configurations, sensitivity settings, and system parameters for optimal performance.
Entering Programming Mode
Accessing the programming functions of the Fire Lite MS-4 panel requires a specific sequence to prevent accidental alterations to the system’s configuration. Begin by ensuring the panel is in a normal, non-alarm state. Locate the system’s keypad – typically integrated into the panel itself. Press and hold the “Enter” key for approximately three seconds.
The display will then prompt for a valid user access code. The default code is often “1234”, but this may have been changed during initial setup; consult previous documentation or the building’s fire safety personnel if unsure. Enter the correct code using the keypad.
Upon successful code entry, the display will change, indicating that the panel is now in programming mode. A different screen or a specific prompt will confirm this transition. Be cautious while in this mode, as any changes made will directly affect the system’s operation.
Zone Programming and Configuration
Within the Fire Lite MS-4’s programming mode, zone configuration is crucial for accurate fire detection and notification. Each zone represents a specific area within the protected building. To configure a zone, navigate to the “Zone Setup” menu using the keypad. You’ll be prompted to select a zone number, typically ranging from 1 to the maximum supported by the panel.
For each zone, you can define its descriptive label – for example, “First Floor Lobby” or “Server Room”. You’ll also assign a device type to each zone, indicating the types of detectors connected (smoke, heat, duct, etc.).
Furthermore, configure the zone’s sensitivity and alarm verification settings. Proper zone programming ensures the system accurately identifies and responds to fire events, minimizing false alarms and maximizing safety. Save changes after configuring each zone.
Sensitivity Adjustments and Settings
The Fire Lite MS-4 allows for precise sensitivity adjustments to optimize performance and minimize false alarms. Access the “Sensitivity Settings” menu within programming mode. Each detector type – smoke, heat, and others – has adjustable sensitivity levels. Higher sensitivity detects smaller disturbances, while lower sensitivity requires more significant events to trigger an alarm.
Carefully adjust sensitivity based on the environment. Dusty or steamy areas require lower sensitivity to avoid nuisance alarms. Utilize the panel’s built-in test modes to verify settings.
Additionally, configure alarm verification settings. These settings require multiple detector activations within a short timeframe before initiating a full alarm, further reducing false positives.
