Quiet and reliable escape door locking system 352M

Special doors require special solutions. Security electric strikes are designed as electrical locking for use under heavy preload and for additional locking on doors in escape routes. The 352M model is suitable for single-action and swing doors and impresses with its very high holding force and particularly low operating noise.

The advantages:

  • Very high holding force

    With a holding force and pre-load release of 5,000 Newton, it is one of the strongest electric strikes in the portfolio and offers one of the highest values on the market.

  • Especially quiet

    Both locking and unlocking are exceptionally quiet. Operation during permanent release is noiseless. 

  • Easy to mount

    The electric strike is easy to mount, no latch bolt lock is needed. The strike counterpart is optionally available with VarioFix technology: sliding screw holes allow for more individual mounting.

  • Universal installation

    The strike is suitable for installation in single-action, swing, revolving, airlock or special doors. The housing A10 is available for surface mounting.

  • New construction: Prisma bolt

    Instead of a conventional  latch, we use a prism-shaped bolt that is fully integrated into the frame and offers more protection against manipulation.

  • New design: contactless sensor

    The door leaf is detected by a contactless sensor. When the door is open, the bolt is completely sunk into the frame, creating a smooth surface and allowing a swing door, for example, to slide past the frame completely unhindered. After closing the door, the magnetic sensor detects when the correct rest position for locking has been reached.

  • Continuous seal

    The motor-driven latch allows a continuous, standardised profile contour, which improves the sound and thermal insulation values. Flanged strike plates are not required. 

  • Certification

    The escape door locking device 352M is tested with our electric escape door controls according to EltVTR and DIN EN 13637:2015.
