DLF2MO-UL

with motorized actuation for double-leaf doors

With the door interlock DLF2MO-UL shaft doors are unlocked and locked silently.
This is ensured by the electric motor integrated in the DLF2MO-UL which can tighten the bolt reliably, silently and with high force.
Door interlocks of DLF2MO-UL type are installed in the door post above the door. The interlock is certified according to UL standard for use on the North American market.

Features:

general:

metal housing with high stability
transparent cover for optimal function control
silent due to buffers in both directions
maintenance-free by permanent lubrication with high quality lubricants (up to -30 °C)
oiled felt rings at the latch bolts for lubrication as well as for sealing against dust and dirt (at X-dimension ≥ 10 mm)
constrained faulty closure for use in passenger lifts
contacts with solid fine silver plating for a reliable function, also at low voltages and currents
auxiliary switch with one contact
extensive range of accessories

special features:

certification for Europe and North America
integrated actuation by maintenance-free, low-noise three-phase motor and decelerated dropping of the bolts
patent protected by Gbm DE 20 2015 105 331 and by patent EP 3 153 454 B1, validated in DE / FR / IT / ES
high starting power
low pull-in current (< 1 A at 24 V)
automatic switching over to reduced holding current (< 0.2 A), energy-saving
safe unlocking by position monitoring even if the bolts are temporarily blocked (incorrect operation)
status display by coloured LEDs
terminal block with all electrical connections
liberation from the pit by cover side triangle or optional pull lever for manual operation
connection for bowden cable or pull rope for unlocking, e.g.
application 1: unlocking from the pit ladder (< 1.80 m according to EN 81-20)
application 2: offset emergency release triangle (< 2 m according to EN 81-20)
