FACILITY SYSTEMS

2-1 RELIABILITY CENTERED MAINTENANCE (RCM) METHODOLOGY. The objective of ITM for fixed fire protection systems is to assure that the systems will function on demand. RCM analysis identifies any defects responsible for system malfunction and how they can be detected and corrected before a fire. A byproduct of RCM analysis is a list of ITM tasks and how often they must be accomplished (frequencies) to achieve a desired reliability (0.99 for this UFC; reference paragraph 1.6). The methodology used to develop the ITM tasks in this UFC is summarized in AFCESA Technical Report, “Risk Based Reliability Centered Maintenance of DoD Fire Protection Systems," January 1999. The model used in the report assumed a system demand of one event in fifty (1/50) years and a task effectiveness (ITM done right) of 99 percent. This RCM analysis emphasized task effectiveness (is it the right thing to do and is it done right?) and timeliness (is it done before a demand?). The resulting list of tasks and frequencies, therefore, considered frequency and probabilities of demands and failures.

2-2 ITM TASK DESCRIPTIONS AND FREQUENCIES

Note: Military Family Housing Systems are addressed in Chapter 3.

2-2.1 Task Descriptions. The ITM tasks in Tables 2-1 through 2-19 and 3-1 through 3-2 were selected to assure the fire protection would function upon demand.

2-2.1.1. Supervised Components. Supervision of components increases the likelihood that conditions or faults will be detected without an inspection activity. In these cases, the ITM task is to respond to the alarm and to test the supervisor device (e.g., valve tamper switch) periodically. Accordingly, the tables reflect the improved fault or condition detection by specifying less frequent inspections. Different frequencies are recommended for monitored and for unmonitored fire alarm control equipment. A monitored system is a system which transmits trouble alarms to a supervisory station.

2-2.1.2. Event-Driven Tests. Some tests should be event-driven. For example, a main drain test is intended to verify the open condition of a control valve to a sprinkler or water spray system, and needs to be done only when the control valve has been operated for maintenance or testing. The frequency indicated in the tables is after valve operation.

2-2.1.3. Excluded National Fire Code Tasks. Some of the tasks the National Fire Codes recommend are not included in the tables. These are tasks which do not improve the operability of the systems because: (1) the faults they detect are not significant; (2) the faults are detected by other tasks or means; or (3) the faults will be self-evident (fix it when it breaks) and do no significantly impair the system.

2-2.1.4. Non-ITM Activities. Inspection activities listed at the end of each ITM table are not part of the ITM program, but part of building overall inspection, and are listed for information only. They were not included in the model used to develop the 99 percent reliability requirements; however, they should be incorporated into each DoD component activity's fire prevention, safety, facility condition, and related inspection/evaluation program.

2-2.2 Fire Detection and Alarm Systems. The type and frequency of ITM tasks for fire detection and alarm systems depend on whether the system is monitored or not. Guidance on the tasks in Table 2-1 is contained in the Inspection, Testing, and Maintenance section of National Fire Protection Association Standard 72 (NFPA 72). Residential smoke detectors are addressed in Chapter 3.

CHAPTER 3

MILITARY FAMILY HOUSING SYSTEMS

3-1 SCOPE. The maintenance concepts for military family housing (MFH) fire protection systems are based on the management and controls unique to the MFH program. In the civilian sector, an owner/tenant makes a personal choice to occupy a dwelling unit and is responsible for their maintenance/repair and any associated fire protection devices. In MFH, occupants are assigned housing units and the housing management activity is responsible for the maintenance/repair of units and associated fire protection devices. Each MFH occupant is required to attend a briefing on their responsibilities as a MFH occupant prior to occupying a new MFH dwelling. These briefings include the occupant's responsibilities for conducting tests and cleaning installed fire protection features. On average, MFH maintenance teams conduct “change of occupancy” maintenance every one to two years; therefore, scheduled maintenance performed by the housing management activity is centered on this change of occupancy.

3-1.1 Residential Smoke Detectors. MFH units are required to have hard-wired smoke detectors. Each installation develops programs to train occupants in the testing and maintenance actions for the smoke detector installed. Actions required as part of change of occupant maintenance by the housing management activity are listed in Table 3 1.

3-1.2 Residential Sprinkler Systems. Some MFH units are also provided sprinkler systems.

3-1.2.1 Residential sprinkler systems in multi-family buildings up to 4 stories are normally constructed in accordance with NFPA 13R, Sprinkler Systems, Residential Occupancies Up To and Including 4 Stories. These systems are maintained in accordance with the tables in Chapter 2 of this UFC. Building occupants are not expected to conduct system tests or maintenance actions.

3-1.2.2 Residential sprinkler systems in multi-family buildings over 4 stories are normally constructed in accordance with NFPA 13, Sprinkler Systems. These systems are maintained in accordance with the tables in Chapter 2 of this UFC. Building occupants are not expected to conduct system tests or maintenance actions.

3-1.2.3 Residential sprinkler systems in one- and two-family dwellings and townhouse-style units are normally constructed in accordance with NFPA 13D, Sprinkler Systems, Dwellings. Installations develop their own programs to train occupants in the testing and maintenance actions required. Actions required as part of change of occupant maintenance by the housing management activity are listed in Table 3-2.

3-2 ITM TASK DESCRIPTIONS. The ITM tasks in Tables 3-1 and 3-2 should be part of the housing maintenance conducted between occupancies.
