The device can be supplemented by an adjustable door switch for monitoring the closed position.
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.
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.

This door interlock is the compact version of the DL(F)1. The device meets the essential quality features of the larger design, however with reduced type diversity. The EL(F)1 is often used for the modernization of lift installations, if no longer available door interlocks of other competitors have to be replaced.
The door interlock EL(F)1 in the version EN 81-21 is particularly suited for lifts with insufficient protective space in the top floor headroom above the lift car or in the shaft pit. By the monitoring of the emergency release triangle, the access to the shaft is controlled with a positively opening safety switch.
The door interlock CL(F) is caracterised by a flat, symmetrical housing where the latch bolt is arranged centrally. The switch for locking mechanism and auxiliary switch are always existing. The bolt stroke is reduced and thus requires lower actuation forces.
