Fire Alarm Detection Service:

Fire alarm servicing is typically broken down into different frequencies and levels of detail.

Daily/Weekly Checks (User-level): These are simple, routine checks that can often be performed by a designated person on-site. They involve a visual inspection of the control panel to ensure no fault or fire signals are present (often indicated by a green LED), and a weekly test of a different manual call point (pull station) to ensure the alarm sounds.

Monthly/Quarterly Inspections (User-level): These are more detailed inspections that include checking batteries, ensuring all devices are free from physical damage or obstruction, and verifying that the system is properly logged.

Semi-Annual/Annual Professional Maintenance: This is a comprehensive service performed by a certified fire alarm technician. It is a legal requirement in many jurisdictions and is essential to maintaining the system's operational integrity.

Key Aspects of a Professional Service

A professional fire alarm service for detectors and the overall system generally includes:

1.    Functional Testing of Detectors:

Smoke Detectors: Technicians will use a specialized aerosol "test smoke" to simulate the presence of smoke and confirm that the detector goes into alarm.

Heat Detectors: A heat gun or similar device is used to apply heat to the detector until it activates at its specified temperature.

Manual Pull Stations: Each pull station is physically activated to ensure it sends the correct signal to the control panel and triggers the alarm.

Beam Detectors and Aspirating Systems: These more complex systems require specific tests to verify their functionality.

2.    Sensitivity Testing and Cleaning:

Dust and dirt can significantly affect the sensitivity of smoke detectors, leading to false alarms or, more dangerously, a failure to detect a real fire.

Technicians will use a professional tool to measure the sensitivity of the detector's chamber. If it's outside the manufacturer's specified range, the detector will be cleaned with a vacuum or compressed air. If cleaning doesn't restore the correct sensitivity, it must be replaced.

3.    Battery and Power Supply Checks:

The service includes testing the backup batteries to ensure they can provide power to the system for the required duration during a power outage.

This often involves a discharge test to confirm the battery's capacity and voltage. Batteries are typically replaced every five years, but this can vary.

4.    System-Wide Checks:

Control Panel: The technician will inspect the main control panel for any fault codes, ensure all wiring is secure, and check the software and firmware versions.

Audible and Visual Alarms: All horns, sounders, and strobes are tested to confirm they are functioning and are not obstructed.

Interface with Other Systems: Fire alarms are often integrated with other building systems, such as smoke vents, fire doors, lifts, and fire suppression systems. The service will test these interfaces to ensure they respond correctly.

5.    Documentation and Reporting:

A detailed report is a mandatory part of the service. It should include the date and time of the service, the name of the technician, a list of all devices tested, and their individual test results.

Any issues found, along with recommended corrective actions, must be noted. This service log is a crucial document for regulatory audits and compliance.
