Product Description
DLF1 & DL1
Standard device with extended range of applications for Swing Type Landing Doors.
All-purpose door interlock for single-leaf doors, which can be adapted individually by several configurations and adaptation possibilities. The connecting terminals for the switch for locking mechanism, door and auxiliary switches are easily accessible on a terminal block and can be connected comfortably.
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
