DAS locks: Autonomous management

Présentation du verrou DAS

Locks for emergency exits are operated safety devices (DAS) in accordance with the French safety standard NF S 61-937. They can be used on all types of doors to protect assets and people.

The concept, patented by Cetexel in 1972, consists of a retractable bolt fitted with a roller and an inclined strike plate. This process ensures that the bolt is not self-locking when pushed. When electrically unlocked, the bolt is pushed upwards. It also ensures that play is taken up when the lock is relocked. Using this principle, the bolt components are arranged so that they do not protrude into the clearance of the passage unit (art-C045).

Functional characteristics :

  • Top door bolt operated by a plunger-core electromagnet or by a motor,
  • Lock consisting of an electric lock mounted on the frame and a strike mounted on the door leaf,
  • Operating power supply: 24 or 48 Vdc.

-Remote control power supply for electromagnetic trigger (DEM): 24 or 48 Vdc less than 3.5 W.
