Clear Fault Indicators: After addressing the underlying cause of the zone fault, reset the Fault LED and Zone Fault LEDs on the repeater panel. To do this, reset the panel.

Test the System: Perform a comprehensive test of the fire alarm system to ensure that the zone fault has been resolved. Activate detectors or call points in the affected zone and verify that alarms are triggered correctly without any further faults being indicated.

How can I test the panel’s LED indicators to ensure they are functioning correctly in the Kentec Sigma Panel?

Use the “Lamp Test” button on the panel to verify that all LED indicators illuminate as expected. If any LEDs fail to light up during the test, check for wiring issues, loose connections, or malfunctioning components..

Why is the panel displaying a Fault LED indicator in the Kentec Sigma Panel?

The Fault LED indicator typically signifies a problem with the panel or the fire alarm system it is connected to. Troubleshoot by checking connections, power sources, and consulting the panel’s user manual for specific fault code explanations.

How Can Alarm and Fault Warnings be Silenced in the Kentec Sigma Panel?

All buzzers (panels and repeaters) can be silenced at any time by pressing the Alarm/Fault warning silence button. The Enable key does not need to be inserted to silence the buzzers.

What should I do if the Kentec Sigma panel’s buzzer is sounding continuously?

A continuously sounding buzzer often indicates a serious fault or system failure. Here’s a step-by-step guide to troubleshoot and resolve this issue:

Check for Alarm Conditions: First, verify if there is an ongoing alarm condition in the building. Look for any indicators or messages on the control panel that may suggest a fire alarm activation.

Inspect Panel Indicators: Examine the LEDs on the control panel to identify any fault or system warnings. Note down any specific indicators that are illuminated or flashing, as they can provide valuable information about the nature of the problem.

Perform System Reset: Attempt to reset the control panel to see if it resolves the continuous buzzer issue. 

Check Power Supply: Ensure that the panel has a stable power supply. Verify that the mains power is connected and that the standby batteries (if applicable) are operational. A power fault or low battery voltage can trigger continuous buzzer alerts.

Inspect Wiring and Connections: Examine the wiring and connections to the control panel, including power supply connections, zone wiring, and sounder circuits. Loose connections or damaged wiring can lead to system faults.

Perform Watchdog Reset: If the panel has experienced a watchdog event, perform a watchdog reset.

When Should a Watchdog Reset be Performed in the Kentec Sigma Panel?

If a watchdog event occurs, the panel will show the FAULT and SYSTEM FAULT LEDs on the front panel, the CPU fault LED inside the panel and the buzzer will sound. This fault can only be cleared by pressing the WATCHDOG RESET button on the PCB inside the panel. This is a serious failure and the control panel buzzer will continue to sound until the watchdog activation is reset. 

To perform Watchdog Reset in the Sigma CP-R Fire Alarm Repeater Panel: 

Locate the Watchdog Reset Button: Open the panel cover to access the internal components. Look for the Watchdog Reset button on the PCB (Printed Circuit Board) inside the control panel. It is typically labeled and easily identifiable.

Press the Watchdog Reset Button: Once you’ve located the Watchdog Reset button, press it firmly to initiate the reset process. This action will clear any watchdog events that have occurred and reset the panel’s microprocessor.

Wait for Confirmation: Wait for a few moments to allow the panel to reset and clear the watchdog event. You may hear a beep or see LED indicators on the panel change to indicate that the reset process is complete.

Monitor Panel Status: After clearing the watchdog event, monitor the panel’s status to ensure that the issue has been resolved. Check for any remaining fault indicators or abnormal behavior to confirm that the reset was successful.

Close the Panel Cover: Once you’ve confirmed that the watchdog event has been cleared and the panel is functioning normally, securely close the panel cover to protect the internal components and maintain the integrity of the fire alarm system.

When Should a Processor Reset be Performed in the Kentec Sigma Panel?

If the microprocessor controlling the panel fails to run correctly, a processor reset should be performed. This action should be taken if the system is behaving abnormally.

To perform a processor reset in the Sigma CP-R Fire Alarm Repeater Panel, follow these steps:
