BS EN () and the use of VSDs for smoke control systems – SCS Group
The Amber document status indicator indicates that some caution is needed when using this document – it is either: Output filters provide additional protection to motor insulation. Details are given for methods of test and the requirements for powered smoke and heat control ventilators fans which can be installed in ventilation systems. Customers who bought this product also bought BS EN Click to learn more. Smoke vent specialists should be approaching clients and specifiers to provide early warning of the impending cost increases resulting from the use of certain types of systems.
What remains to be seen is whether clients and specifiers appreciate that systems will become more costly due to sn 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.

VSDs also provide useful soft-start functionality to reduce large fan 1210-13 currents reducing stress on essential power supply networks and generators. The numerical analysis results showed that under a condition where the height of an opening is less than 1. We believe in a better way of delivering building engineering services.

Their committees work with the manufacturing and service industries, government, businesses and consumers to facilitate the production of British, European and International standards. Your basket is empty. Inverter drives also known as variable speed drives or VSDs are commonly used in smoke control applications to limit and modulate fan speed to suit a particular system design.

Using this approach would allow fan and VCD selection methods to remain un-changed, meaning that installers and system designers would then not be forced to accommodate larger motors, fans or additional control equipment into their design.

This combination is certified under BS EN Scientific Research An Academic Publisher. 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 the smoke exhaust fan, and the smoke density within the space drops sharply in all opening height conditions, thereby getting close to zero.
The effect of these changes on some common smoke ventilation systems are summarised in the following table:. Smoke and heat control systems. Again there may be more recent versions of the document. Once this is appreciated, the appeal and advantage of using a fully tested and certified matched smoke vent fan and VSD solution should then be recognised.
