Product Code: ELF1

Product Description

ELF1 + EL1 EN 81-21

Standard device for single-leaf doors
The door interlocks 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.

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.
