High security deadbolt Technilock® L4
Fail-unlocked
Product description
Electromechanical drop bolt for use in high security areas
Features of the fail-unlocked version:
In the fail-unlocked version, the door is always unlocked without power. The focus is on opening in the event of danger
In the event of a power failure/fault, the lock is opened
Application:
When a high locking pressure is required, but the door must open in the event of a power failure
Actuation by fire alarm/smoke alarm system is possible to ensure safe exit from the Hazardous area.
Cannot be used as an electric locking system in accordance with EltVTR or DIN EN13637
Overview of Advantages
- Reliable impact resistance
- Bolt side load breaking force of up to 20,000N
- 80 N bolt pre-load for fail-locked and fail-unlocked models always ensures reliable unlocking
- Status monitoring via programmable monitoring contacts, additional relay circuit board provides potential-free monitoring contact
- Programmable unlocking time
- Sequence control system for locking with mechanical and electrical query of the door status
- Integrated error log and undervoltage indicator make fault rectification easier. Malfunctions can be traced on site and quickly verified for repair purposes, with rapid error analysis, high available, short downtimes
- Integrated microprocessor control unit: no additional external control unit required
- Vertical installation possible in the frame or door leaf
- Horizontal installation possible in the frame top
