DL(F)1 EN 81-21

Door interlock with integrated monitoring of the emergency release

The door interlock DL(F)1 with integrated monitoring of the emergency release is particularly suited for lifts with restrictive pit depth or top floor headroom above the lift car. At this version the emergency release triangle is monitored by 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 DLF1 for use in passenger lifts
  • contacts with solid fine silver plating for a reliable function even at low voltages and currents
  • extensive range of accessories

special features:

  • patented monitoring of the emergency release base side with positive opening safety switch (EN 81-21)
  • optional: with bistable switching function of the monitoring by a mechanical detent the contacts remain actuated until the reset is made via a short voltage pulse at the electromagnet.
  • terminal block with all electrical connections
  • optional: auxiliary switch
  • connection for bowden cable or cable pull for actuation or unlocking available, e.g.
    application 1: unlocking from the pit ladder (< 1,80 m according to EN 81-20)
    application 2: actuation by bowden cable as alternative to pull rod
  • compatible with no longer available KRONENBERG door interlocks (TV1, TVL1)
