Hinged doors with a seal that stops smoke as well as fire – on fire compartment boundaries, escape routes and stairwells. Most fire victims are killed by smoke, so designs often require S (smoke control) and C (self-closing) in addition to the EI class.
Sa or S200 and the EI class are stated in the fire safety report or bill of quantities. Smoke-control doors must always close by themselves, so we supply them with a closer and, where needed, an electromagnetic holder that releases them on a fire alarm signal.
Declarations of performance, conformity and installation, a label with class and serial number, and installation and maintenance instructions – the documents requested at building inspection.

Frequently asked questions
What do Sa and S200 mean?
Sa means cold smoke leakage is limited; S200 means the door was also tested with smoke at 200 °C. The marking is added to the class, e.g. EI2 60-S200C5.
Are smoke-control doors also fire doors?
Usually yes – we supply doors with both an EI class and an S rating. The fire safety report states which combination is required.
May smoke-control doors be kept open?
Only with an electromagnetic holder linked to the fire alarm that releases them to close in a fire. Wedging them open or removing the closer is not allowed.
