Fire Alarm System – Module 6

Course Overview: Fire Alarm System Maintenance (FAS)

Course Description This module emphasizes the critical importance of regular maintenance to ensure Fire Alarm Systems remain reliable, compliant with safety codes, and free from nuisance alarms. It details the procedures for both proactive care and reactive troubleshooting.

Core Modules & Topics

  • Maintenance Strategies
    • Preventive Maintenance: Scheduled inspections designed to identify issues before they cause system failure.
    • Corrective Maintenance: Reactive procedures performed to repair or replace components after a fault or failure has occurred.
  • Standardized Maintenance Schedules
    • Weekly Checks: Visual inspection of the Control Panel, LEDs, and power supplies to ensure normal status.
    • Monthly Checks: Functional testing of backup batteries and output devices like hooters and strobes.
    • Quarterly Checks: Testing specific zones and initiating devices (smoke/heat detectors) to verify alarm transmission.
    • Annual Checks: A comprehensive full-system audit, including detector sensitivity testing, cable integrity checks, and full load testing.
  • Practical Procedures & Tools
    • Detector Cleaning: Using vacuums, compressed air, or soft brushes to remove dust and debris from optical chambers.
    • Battery Care: Cleaning terminals and measuring voltage to prevent power failure.
    • Essential Tools: Utilization of multimeters, smoke/heat testers, and aerosol sprays for compliance testing.
  • Troubleshooting & Documentation
    • Common Faults: Diagnosing and fixing Ground Faults (wiring touching earth), Open Circuits (broken connections), and Short Circuits.
    • False Alarm Management: Identifying environmental triggers like dust, insects, or steam and applying fixes.
    • Record Keeping: Maintaining a detailed System Logbook to track dates, faults, technician names, and replaced parts.

Key Learning Outcomes

  • Execute maintenance tasks according to Weekly, Monthly, Quarterly, and Annual schedules.
  • Properly clean and test detection devices using industry-standard tools.
  • Diagnose common wiring faults and document all activities in a compliance logbook.
