Product Description

DLF1 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.

If you are replacing an existing old type door lock then please quote the full code on the White sticker as per PFD Document (Kronenberg Identification Label). The lock often needs to be removed for this code to be visible. Please see picture above.
