Maintaining fire alarm systems is vital. A fire alarm system that is not properly maintained may not function when needed, leading to irreparable damage. In this article, we will discuss the key principles and essential steps to keep these systems operating optimally.

Daily and weekly inspections: quick and basic checks

These inspections are performed to ensure the system’s immediate performance, and you can perform them easily and without the need for special tools:

Check the central panel: Make sure the panel lights (LEDs) are in a normal state and no warning or error lights (such as Fault or Trouble) are on.
Power supply check: Ensure the system is properly connected to the mains and that the backup batteries are active. The batteries should be visually inspected for leaks or corrosion.
Visual inspection of equipment: Check detectors, sirens, and fire alarm buttons for physical damage, dirt, dust, or any obstructions.

Monthly Inspections and Tests: Comprehensive Checklist

These tests are performed regularly and in more detail for each component of the system. It is recommended to have a monthly checklist and record the results in it:

Test detectors: Test each detector (smoke, heat, gas, etc.) individually with the appropriate tool (such as smoke test spray or heat tester) to ensure it activates on time.

Test the Call Points: By pressing each button, ensure that a signal is sent to the central panel and that the sirens and flashers are activated. After testing, reset the button with the special key.

Test sirens and flashers: Make sure the sirens are loud enough and the flashers are clearly visible and can be heard and seen throughout the building.

Backup battery test: By disconnecting the main power, make sure the backup battery is automatically activated and the system is functioning properly in this mode. Then check the battery voltage status.

Disadvantages of manual systems

Dependence on human resources: If a trained person is not present, or if a fire occurs during non-working hours, these systems are practically useless.
Delayed response: Manual activation takes time and the fire may spread rapidly in the first few seconds.
Risk to the user: Using these systems exposes the individual to direct risk of fire and smoke.

Specialized service and maintenance: annual inspections

Annual inspections should be carried out by a qualified and authorized technician. At this stage, all system components are carefully checked and tested:

Detector sensitivity test: Using specialized tools, the technician checks the sensitivity of the detectors to ensure that they are neither too sensitive (leading to false alarms) nor too slow to respond.
Cleaning and Calibration: Detectors are professionally cleaned and, if necessary, calibrated to restore their performance to its original state.
Cabling and Connection Inspection: All cables, connections, and system circuits are inspected for damage or disconnection.
Reporting and Documentation: After completing the tests and inspections, the technician will provide a complete report including the condition of the system, the date the service was performed, and any issues or recommendations. These reports must be retained for a minimum of three years.

Key tips for better maintenance

- Compliance with international standards: Refer to national and international standards such as NFPA 72 for maintaining fire alarm systems.
- Record keeping: Keep a maintenance logbook and record all tests, inspections, part replacements, and repairs, with dates.
- Employee training: All employees and people present in the building must be familiar with how the system operates, the location of fire alarm buttons, and the necessary actions in the event of an alarm.
By following these steps, you can ensure the proper and timely operation of your fire alarm system in emergency situations and protect your life and property in the best possible way.
