Panic Exit Devices BS EN 1125

It is desirable that the doors at final exits in public buildings, places of entertainment, shops etc should be fitted with panic devices operated by a horizontal bar or touch bar. The emphasis for products covered by this standard is on safe exit rather than security.

 
providing details on product types, classification by use, test cycles, door mass, corrosion resistance as well as definitions, product performance requirements, test apparatus, test methods and marking products.
  
The main purpose of the performance requirements of this standard is to give safe and effective escape through a doorway with minimumeffort and without prior knowledge of the device i .e.for lock doors on escape routes where panic situations can be for seen.
 
BS EN 1125 Classifies panic exit devices by using a 9 digit coding system, each digit referring to a particular feature of the product Measured against the standards performance requirement.
