Product information
Technilock ® L4 High Security Bolt
General
The Technilock ® L4 high security bolt is a motorized power cam bolt for the locking of high security areas. It
is suitable for horizontal (in the door frame) or vertical installation in the door frame and in the door leaf
and can also be installed in swing doors and double acting swing doors. Alternatively, the door bolt can be
installed as the main lock, for which purpose three are lock versions available with a 9 mm handle follower.
The bolt position and door position are monitored by contacts. An additional external control is not
necessary.
Technilock ® L4 is offered in “fail-unlocked” and “fail-locked” versions with additional control latch, as well
as a “fail-locked” version with additional control latch and follower. (Fig. 1). The control latch senses the
door position so that the door can be closed without actuation of operating current.
Functions
When the door closes, the bolt automatically extends and is locked.
Special magnets are installed in the striking plate for the Technilock ® L4 . If the magnet of the Technilock ® L4
is recognised while the door is closed, the bolt automatically extends and is locked. Tampering with the
bolt is prevented, because the bolt only extends while the door is closed.
If the door bolt cannot extend completely, repeated attempts are made to extend the door bolt. If this is
unsuccessful, an alarm is triggered automatically.
The Technilock ® L4 offers
· extremely high resistance against attempts at forcing and tampering,
· very high impact resistance, indestructible up to 20,000 N,
· automatic locking,
· monitored locking with extensive reporting and monitoring functions,
· automatic striking plate recognition.
