LB-series is a new product of PERCo company, which is unique at the market. In LB-series locks voltage is supplied through contacts in the locking bolt of LB-series lock. Power cable and control cable are connected through the strike plate in the door frame, not through the door leaf, which makes installation easier and provides aesthetically pleasing exterior of the door.
In the LC-series locks the control cable is connected in the ordinary way, through the door leaf. LC-series locks have two operation modes - day-time (with small bolt throw) and night-time (with enhanced bolt throw).
Differing in control mode (normally open/closed) and in centre-to-centre spacing, locks of LB series are presented in 6 models, while LC series locks are presented in 4 models.
Voltage is supplied through the groups of contacts in the locking bolt and in the mating lock under the keeper. Installation is made through the door frame, which allows saving door and avoid using adapters.
When the door is open the locking bolt moves inside the housing, the blocker roll pulls out automatically. When the door is closed the blocker roll starts sliding on the strike plate and moves inside the lock housing that causes the locking bolt to pull out and the lock to close automatically.
Bolt throw is 15mm long.
The locks can be installed in standard and profile doors. For thin metallic profile doors the special LBP locks are designed.
The locks are universal and can be installed both to the right-hand and to the left-hand doors without changing bolt position.
PERCo-LC series locks have two operation modes: day-time and night-time.
In day-time locking mode the bolt throw is 11 mm, and it is 18,5 mm in night-time locking mode, the additional bolt throw is made without a skew avoiding the possibility to push out the door.
LC lock can be installed to the right-hand and to the left-hand doors. Necessary lock location may be performed easily by relocating of the bolt during the lock installation.
