The manual periodic tests verify smoke control system responses to alarm zone inputs. Some of the manual testing must be performed with the system operating on emergency power, if applicable. An alarm must be generated in each zone. The system and equipment responses must be verified and recorded. Manual periodic testing should occur when the building is not occupied.

Automatic smoke control matrix
An automatic smoke control matrix (Table 5 on page 28, dedicated; Table 6 on page 28, nondedicated) shows each piece of mechanical equipment and each building zone. The matrix shows the automatic response of each piece of equipment to an initial alarm for each smoke zone. It also shows the mode of each zone based on an alarm in another zone. Commands from the FSCS may override the automatic responses. The matrix must be engineered for a specific project.
