DL(F)1 EN 81-21
with monitoring of the emergency release
The door interlock DL(F)1 with integrated monitoring of the emergency release is particularly suited for lifts with insufficient protective space in the top floor headroom above the lift car or in the shaft pit. At this version the emergency release triangle is monitored by a positively opening safety switch.

Dimensions DLF1-R-X15(u).10.2/11
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 dust and dirt (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
- optional: auxiliary switch with one contact
- extensive range of accessories
special features:
- 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: actuation by bowden cable as alternative to pull rod
- compatible with no longer available KRONENBERG door interlocks (TV1, TVL1)
