Fig. 3.  LB-72.2 electromechanical lock layout

Fig. 2.  LB-72.2 electromechanical lock installation layout

LB-72.2

  is a normally-open  electromechanical mortise door lock (hereinafter 

– the lock), designed to be used as an operating device as a part of access 

control system (hereinafter – ACS) to control light and medium office doors. 

Lock features:

  the lock has a unique construction, allowing to connect lock control cable

  through the strike plate in the door frame, not through the door leaf, which

  makes installation easier;

  the lock can be installed in wooden and non-metallic doors 38-50 mm thick;

  a universal lock construction enables its installation on both right-handed

   and left-handed doors;

•  the lock is designed for use with standard lock cylinders;

  all components of the lock and strike plate have corrosion-resistant coating;

•  the lock is resistant to self-opening (for instance,  as a

  result of a hard kick

   on the door);

•  the lock has low power consumption (max 2 W

);

  the design of the lock does not require preventive maintenance and

   lubrication from the customer for the entire period of operation;

•  the lock opens when de-energized; 

  when energi

z

ed the lock closes automatically at shutting the  door  

 

   (by a signal from ACS);

 

The lock with regard to resistance to environmental 

exposure

 complies with 

GOST 15150-69, category NF4 (operation in premises with climate control).

Operation  of  the  lock  is  allowed  at  ambient  air  temperature  from  +1°C  to 

+40°C and at relative air humidity of 75% at +15°C.

The lock has a marking in the form of label located on its housing. The label 

contains product name, its serial number, the manufacture date and its main 

technical specifications.
The  product  is  packed  in  a  carton 

box,

  protecting  it  from  being  damaged 

during transportation and storage.

Box dimensions (

L

 × W × H) ...................................................... 12×22×4 cm

Gross weight ............................................................................... 

max. 0.7 kg

Lock  storage  is  allowed  indoors  at  ambient  air  temperature  from
