Design considerations for smoke control

Smoke feedback

Smoke feedback occurs when smoke enters a pressurization fan intake and flows into protected spaces. Design techniques reduce the probability of smoke feedback:

•Supply air intakes located below openings from which smoke might flow, such as building exhausts, smoke shaft outlets and elevator vents.

•Automatic shutdown capability to stop the system in the event of smoke feedback.

For more information on smoke feedback, refer to SFPE 1995, Fire Protection Engineering Handbook.

Smoke alarm annunciation Smoke alarm annunciationSmoke alarm annunciation Chapter 7 Programming From requirements 33.2.1 and 33.2.2, we can see that there is a decoupling between annunciation and reaction. The series of network variables shown in Figure 54, nvoSwitch05 through nvoSwitch12, are used to directly control the smoke alarm LEDs on the FSCP. For example, a smoke alarm for floor 1 is received. The mechanical system reacts by pressurizing floor 2 and exhausting floor 1. Following that, floor 2 goes into smoke alarm. The alarm needs to be annunciated even though the mechanical system does not react. In this case, nvoSwitch06 passes the smoke alarm state to MP580-3by using a custom binding. At MP580-3,the binary output that controls the floor 2 smoke alarm LED is turned onFigure 55.
