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 ba be increased.
The most practical option, from a system integration point of view, would be to use a fully tested and certified matched smoke vent fan and VSD solution, which fully complies with EN Free to use BIM project management tool provides step-by-step help to define, manage and validate e for information development and delivery at each stage of the asset life cycle in level 2 BIM projects.

BS EN 12101-3:2015
Specification for powered smoke and heat exhaust ventilators AMD Withdrawn. Pressure control systems relying on fan speed modulation are unable to comply with this condition.
You may experience issues viewing this site in Internet Explorer 9, 10 or 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.
Many manufacturers provide a fire mode option that disables the control functions and motor protection in an emergency and allows the motors to run to destruction if necessary; however, as there have been very few tests carried out under fire conditions there is a lack of certainty about their performance.

Inverter drives are commonly used in smoke control applications. Worldwide Standards We can source any standard from anywhere in the world. Take the smart 1210-13 to manage medical device compliance.
The Red document status indicator indicates that the document is 1211-3 old version The document has likely been withdrawn by the publisher, also the meta data presented here may be out of date as it is no longer being maintained by the editorial teams at NBS. 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.
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. Specification for powered smoke and heat 1210-3 ventilators No longer current but cited in Building Regulations guidance.
Output filters provide additional protection to motor insulation. Open Journal of Fluid DynamicsVol. Find Similar Items This product falls into the following categories. Click image to download a PDF of this article to read or print later.
The Amber document status indicator indicates that some caution is needed when using this document – it is either: Smoke and heat control systems. VSDs also provide useful soft-start functionality to reduce large fan start-up currents reducing stress on essential power supply networks and generators.
