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.
Holds the bolt of opened door unlocked even during power failure
The cylinder function can be used to lock and unlock manually. After manual locking, the bolt in fail-locked version cannot be unlocked via the actuation signal. Manual locking can only be cancelled by unlocking via the locking cylinder
Mechanical steering device
Direct activation by a fire alarm/smoke detection system is not possible

Overview of advantages
