Fire Alarm System Maintenance Work Classification

Our maintenance tasks are classified according to the table below

Category

Subcategory

Description

Planned Maintenance

Time-based Maintenance

Detects system deterioration and prevents failure by systematic inspection and monitoring undertaken at predetermined time intervals.

Condition-based Maintenance

Corrective maintenance work performed, as a result of significant deterioration or failure, to restore the system to full functionality.

Statutory Maintenance

Actions performed to provide the minimum level of maintenance to meet mandatory requirements of NFPA or Code of Practice such as SANS 10400 Part 1. (Often includes Some of the Time-based and Condition- based maintenance tasks).

Unplanned Maintenance

Routine & Breakdown Maintenance

Unplanned and reactive maintenance actions performed to restore the system to full functionality, as a result of an unforeseen failure.

Incident Maintenance

Unplanned maintenance actions to restore the system to full Functionality as a result of damage resulting from a lightning strike, vandalism, fire or other accidents.

Generally, the more rigorously planned maintenance, and in particularly time based preventive Maintenance is implemented; the less likely is the need for costly and disruptive unplanned Maintenance. The code of practice for system design, installation and servicing of a fire detection and alarm system, SANS 10400, SANS 10139 and the NFPA regulations, lists the recommended tasks to be performed as part of the time-based preventive maintenance program. The fire alarm system is most likely to perform its critical life-safety functions at all times if these maintenance tasks are performed dutifully.

Time-based preventive maintenance according to SANS 10400

Daily tasks will be included in weekly inspections, weekly tasks in monthly inspections, and so on.

Daily

  • Check the control panel to ascertain that it shows normal operation. Otherwise log The failure.
  • Ensure that any fault reported the previous day has received attention
  • Visually inspect backup batteries
  • Check all fault indicators and circuits by simulating a fault condition
  • Check each detector for correct operation in accordance to manufacturer’s Recommendation

(please note that this is over and above the Daily inspection noted in the proposal)

Weekly

  • Ensure that the system is capable of operating under alarm conditions by operating At least one detector or call point on one circuit (zone or loop). For systems with 13 Circuits or less, each circuit will be tested in turn. For systems with more than 13 circuits, then more than one circuit will be tested each week so that the;
  • Interval between tests on one circuit does not exceed 13 weeks.
    We will Check any printers to ensure that reserves of consumables are adequate for 2 weeks normal usage
  • Visually inspect whether structural or occupancy changes have affected the Requirements for the positioning of call points, detectors and sounders.

Monthly

  • Simulate mains failure to automatically start standby generators/batteries to power the fire alarm system for at least 1 hour. Check for malfunctions. Restore to normal supply and check generator start-up battery & charger. Fill up fuel tanks, top up oil and coolant if necessary.

Quarterly

  • Re examine entries to log books to ensure that the necessary actions were taken.
  • Examine batteries and their connections and test them as specified by supplier to Ensure that it is not likely to fail before the next inspection.
  • Check Alarm functions of the panel by operating a detector or call point in each zone
  • Check Alarm sounders and automatic link to remote centers, if any.
  • Check all ancillary functions of the control panel, where possible.
  • Visually inspect the control panel for signs of moisture ingress or other deterioration.
  • Visually inspect to confirm that a clear space of at least 750mm is preserved in all directions below each detector, that detectors are sited in accordance with code of Practice clauses 12 &/or 13 and that all call points remain unobstructed and conspicuous.
  • These tests will be done by a competent person, and upon completion, a certificate of testing will be issued to the responsible person.

Annually

  • Visually check all cable fittings and equipment are secure, undamaged and adequately protected.
  • Record any defects in a logbook and upon completion, a certificate of testing is issued to the responsible person.
