331U81F escape door strike 331U81F
Escape Door Strike 331U80 is especially designed to lock doors along escape routes. Our Model 331U80 is also suitable as an additional locking device for fire doors. Thanks to its reliable unlocking under pre-load (max. 5,000 N), it is primarily used in doors which are subject to escape route requirements. The 331U Model Series is guaranteed to work reliably in interlock systems, on soundproof doors and on doors where pressure is expected to act on the electric strike latch due to the structural design.
Overview of Advantages
- Sturdy design for demanding requirements
- The escape door strike is designed as a supplementary locking device on fire doors only, independent of the main lock. It must not be fitted as a mating component for the main lock under any circumstances, as otherwise correct functioning of the fire door can no longer be guaranteed. The escape door strike and its respective Mating Component 807-10 have been tested in accordance with applicable regulations and are approved as suitable for electrical locking systems in doors along escape routes.
