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
