High security deadbolt Technilock® L4

Product description

Electro-mechanical door bolt for use in high security areas.

Features of the fail-locked version

  • The fail-locked version always keeps the door closed in case of a power failure. Here, the focus is on secure locking (security)
  • A secure closure is provided in the event of a power failure/fault
  • Very high locking pressure and high impact resistance
  • Static bolt load in accordance with DIN 18251 20,000N (destruction-proof)
  • Extended range of functions: Two additional functions ensure daily operations can continue in the event of power failure and breakdowns. Emergency locking also takes place in the event of a breakdown.
