Tier I: Most critical spaces. These spaces are monitored for pressure, temperature, humidity, and air exchanges. Local display and linked to BAS for critical monitoring by engineering and archiving of data.Tier II: Monitoring pressure only. Local display and linked to BAS for monitoring by engineering and archiving of data.Tier III: Monitoring pressure only locally, however, not remotely via BAS.Tier IV: Monitoring of construction projects
