Hold-open sys­tems in accor­dance with EN 1155

App­li­ca­tion areas
Fire barriers in escape and rescue routes such as fire and smoke pro­tec­tion doors. These doors are normally used in kindergar­tens, hospi­tals, schools, hotels and residen­tial homes for the elderly. In addi­tion to fire pro­tec­tion, their pur­pose is to pro­vide barrier-free access to children, elderly per­sons and per­sons with disabili­ties. As a whole they the­re­fore ensure a smooth flow of public and goods traffic during daily ope­ra­tions.

Design:

A hold-open system con­sists of the fol­lowing compon­ents

• at least one fire detec­tion ele­ment for smoke and heat detec­tion, the ORS 142 or ORS 142 W optical smoke switch, for example
  
• one power supply unit for energy supply, the NAG 03 power supply and tripping unit, for example
  
• a tripping unit to ini­tiate the clo­sing ope­ra­tion, the NAG 03 power supply and tripping unit, for example
  
• a sur­face-mounted/flush-mounted manual tripping device as inter­rupter
  
• a hold-open device that holds the clo­sing barrier open, for example
  
  
  • an electrome­cha­nical hold-open device inte­g­rated into the slide rail (FE-OTS 73x or FE-VTS 735)
    
  • an inte­g­rated hold-open system (OTS 73x FL or VTS 735 FL)
    
  • a hold-open magnet (electroma­gnetic)
