Follow these steps to resolve the issue:

• 1Verify that the power supply to the entire alarm rack is stable and within rated voltage.
• 2Check the status LEDs on the main control board – a red lamp indicates a fault.
• 3Test the trigger point by manually pulling the fire alarm pull‑station or using a smoke simulator.
• 4Inspect the wiring between the smoke detector and the control panel for breaks or loose connections.
• 5If the alarm still fails, replace the suspect detector with a known working unit and retest.

Follow these steps to resolve the issue:

• 1Confirm that the UPS or backup battery is fully charged and the battery voltage is within spec.
• 2Check the main supply cable for any signs of wear, corrosion or loose terminations.
• 3Inspect the breaker panels for tripped or overloaded breakers that might be cutting the alarm supply.
• 4Verify that the surge protection device is functioning – replace it if the indicator LED is off.
• 5Run a continuity test on the main power cable and replace it if resistance exceeds manufacturer’s threshold.

Follow these steps to resolve the issue:

• 1Clean the detector lens and housing with a dry microfiber cloth to remove dust or debris.
• 2Confirm that the detector is positioned at the correct height (usually 1.5–2.0 m from the floor).
• 3Use a certified smoke test kit to generate a controlled smoke concentration and observe the detector response.
• 4Inspect the wiring harness for any breaks or disconnections between the detector and the panel.
• 5If the detector still does not fire, replace it with a new unit from the same batch.

Follow these steps to resolve the issue:

• 1Ensure the GSM module is properly seated and the SIM card is active with sufficient credit.
• 2Check the network signal strength on the GSM module; reboot the module if signal is weak.
• 3Verify the notification configuration on the control panel – correct phone numbers and message templates must be set.
• 4Test the module by sending a manual SMS from the panel’s test menu.
• 5If the test fails, replace the GSM module or contact the service provider for network issues.
