Level 1 teaches Enclosure Fundamentals and is targeted at Witnesses, Authorities, Designers, and Consultants. Testers must also pass this level of training.

Enclosure Design

NFPA 2001 requires an enclosure integrity test to assure an adequate clean agent retention time.

Agents runs out too fast to prevent re-ignition. A more important reason however, is that the enclosure is the first line of defense against smoke.
Smoke events in adjacent rooms or even outdoors, can cause false discharges.
The suppression system may actually cause smoke to be pulled into the protected enclosure.

Relief vents invariably suffer from one or more of the following problems:

Vents are blocked, non-existent or don’t open at all risking enclosure damage

Learn how to correctly specify enclosure integrity, relief vents and fire-stopping to avoid common and costly pitfalls. Save your clients money and greatly improve their fire protection for no additional cost. Use CA2001software as a design tool to optimize suppression system performance. Topics include:

How Unintended Mixing Occurs
Good Pressure Relief Vent Design
Good and Bad Enclosure Designs
Wind Losses can exceed NFPA prediction
Fail-Safe Design
Writing an Enclosure Specification
Passive Fire Protection Design
Exceptions to the 10 minute Pass/Fail Criteria
Selecting the best Clean Agent
Specifying the Measurement of Installed Vents

Witnessing a Test

An easy checklist method will be taught where the most common tester errors will be revealed. Use the CA2001 Windows Software to review enclosure test results and get technical support on doubtful tests. The Field Calibration Test will be demonstrated since it is the easiest way to ensure the system, tester, and software are all functioning correctly.

Level 1 Certification Exam

A different exam is written by witnesses, designers, and testers. Witness and designer exams focus on only those topics that are specific to their role. Testers complete the witness and design and additional questions relating to testing so they have a wider understanding of the issues.
