EL(F)1 EN 81-21
for single-leaf doors
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.
