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
