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
