1.5 QUALITY ASSURANCE

A. Installer Reliability: The installer shall possess a valid State of

Michigan contractor's license. The installer shall have been actively and successfully engaged in the installation of five similar sized clean agent special suppression systems for the past ten years. The installer shall maintain or have access to a clean agent recharging station.

C. Clean Agent Hold Time

Per NFPA 2001 the required clean agent concentration shall be at 85% for ten minutes after discharge. Existing permeability of Room 5281 enclosure delimitations will result in losses of extinguishing agent.

This can prevent an effective extinguishing concentration or the required hold time from being reached or maintained. Subjective visual assessment of a protected enclosure’s leak tightness is not precise enough. Contractor shall be required to perform a blower door air leakage test after the contractor has sealed all room perimeter cracks, completed the required perimeter 1 hour stopping measures, installed new gaskets on exit doors, etc.

Room 5281 must have the following characteristics:

MODERNIZATION (EHRM)

• Windows should not open or should only be openable with special tools. Existing windows shall be provided with additional gaskets.

D. Blower Door Room Air Leakage Test

For function of the fire suppression system known room permeability is a crucial factor.

A test shall be done by the contractor after he feels all of the required new crack sealing, gasketing and auto-closure work is complete to aide in calculating the amount of clean agent required.

Based on multiple pressure differential and air throughout measurements a leakage surface as well as the theoretical hold time of the concentration capable of extinguishing fires can be calculated. In addition any leakage observed can be addressed for additional sealing measures.
