Fire Protection System Maintenance


Maintaining reliability throughout the entire life cycle of a fire protection system involves three distinct and equally important tasks which must be performed on a periodic basis:

1. Visual inspections – A visual examination of the equipment to verify that nothing has changed from the initial design and installation that would affect its performance. A proper visual inspection should consider whether building modifications or occupancy changes would have an impact. Another important consideration is a change in environmental conditions. Increased cooling systems to support greater heat loads might be producing airflow rates impacting the need to adjust the design spacing of the ceiling smoke detectors. 

A minimum standard for these periodic visual inspections can be found in Table 14.3.1 Visual Inspection Frequencies of the National Fire Alarm and Signaling Code (NFPA 72).

2. Functional testing – Functional testing is intended to validate the functionality of the fire protection system. Tests are performed by operating each component of the system to assure it performs as required in the case of an actual emergency event. A simple example of this sort of testing is to pull the lever of each Manual Fire Alarm Pull Station to ensure it performs as intended and initiates the required alarm condition. A proper testing program should also include testing the operation of all Emergency Control Functions in the system such as elevator recall or HVAC shutdown. NFPA 72, the National Fire Alarm and Signaling Code (2010 Edition), requires these functions to be tested at the same frequency as the device which initiates the action. 

A minimum standard for these periodic tests can be found in Table 14.4.5 Testing Frequencies and Table 14.4.2.2 Test Methods of the National Fire Alarm and Signaling Code (NFPA 72).

3. Maintenance activities – The work necessary to keep the fire protection system operating properly. One form of maintenance is simply a response to a failure identified by a visual inspection or a test of the equipment. Another important form of maintenance is of a preventative nature. Many components in a fire protection system will require preventative maintenance at a prescribed frequency. These maintenance activities address components that degrade over time, have a finite lifespan or require periodic resetting or calibration. For example, most fire alarm systems utilize lead-acid type batteries as a secondary (backup) power supply. Although NFPA codes require routine testing to verify voltage levels are at an acceptable level, a preventative maintenance requirement exists requiring their replacement at 5 years from the date of manufacture.

Many overlook the need to visually inspect the fire system and concentrate only on the functional testing of the components. However, each of these tasks are necessary and contribute to the assurance of a fire system that is ready to perform in the case of a fire. Fire-prevention codes specify the proper maintenance and repair of these systems.
