EL(F)1 EN 81-21

Standard device for single-leaf doors

The door interlock EL(F)1 in the version EN 81-21 is particularly suited for lifts with restrictive pit depth or top floor headroom above the lift car. By the monitoring of the emergency release triangle the access to the pit is controlled with a positively opening safety switch.

Features

general:

  • metal housing with high stability
  • transparent cover for optimal function control
  • silent due to buffers in both directions
  • maintenance-free by permanent lubrication with high quality lubricants (up to -30°C)
  • oiled felt ring at latch bolt for lubrication as well as for sealing against dirt and dust (at X-dimension 10 mm)
  • constrained faulty closure at ELF1 for use in passenger lifts
  • auxiliary switch as normally closed contact and/or normally open contact with galvanically separated contacts possible
  • contacts with solid fine silver plating for a reliable function even at low voltages and currents
  • extensive range of accessories

special features:

  • technology of the DL(F)1 in compact design
  • contact holder insert with switch for locking mechanism and optional double auxiliary switch
  • screw terminal with pressure plate for both-sided line connection
  • options for door switches for monitoring the closing position:- internal door switch (not adjustable)- external adjustable door switch (PZ73)
  • optional: patented monitoring of the base side emergency release with positive opening safety switch (EN 81-21)
