BS EN () and the use of VSDs for smoke control systems – SCS Group
The use of inverters in emergency conditions has long been a topic of conversation within the industry. What remains to be seen is whether clients and specifiers appreciate that systems will become more costly due to the need for expensive VSD filters, oversized fan motors and increased power supplies and that plant space requirements needed to accommodate fans and control panels will need to be increased.

Smoke and heat control systems. On the other hand, if the smoke exhaust fan operates after the fire source disappears, smoke is directly exhausted to the outside due to the operation of sb smoke exhaust fan, and the smoke density within the space drops sharply in all opening height conditions, thereby getting close to zero.
