Mortise Electromechanical Lock For Entrance Door ST-DB650MC With Electronic Control And Mechanical Unlocking Option

The range of Smartec equipment for access control systems has been expanded with the ST-DB650MC electromechanical lock, which supports both electronic control and mechanical unlocking with a key (optional).

A durable stainless steel housing, special protective coating of internal elements and a working range from -30 to +55 °C allow you to install an electromechanical lock on an entrance door, gate or wicket. At the same time, the ST-DB650MC supports normally closed and normally open operating modes, provides a holding force of 450 kg, is characterized by low power consumption and heat emission and has a deadbolt fixation monitoring line output.

High performance characteristics allow using this electromechanical lock outdoors and installing it on an entrance door, wicket or gate. ST-DB650MC has a stainless steel body and a special protective coating of internal elements, while it functions stably in a wide temperature range - from -30 to +55 С. Due to the durable steel bolt, the output of which is 13 mm, and the holding force of 450 kg, the electromechanical lock is effective in use on relatively heavy entrance doors, and it does not matter whether they open inward, outward or like a pendulum.

The operating mode of the ST-DB650MC – normally open (NO) or normally closed (NC) – is selected using two screws located on the rear side of the lock. In the NO mode, the electromechanical lock ensures free opening of the door when the power is turned off and will be the optimal choice for protecting the premises of offices, shops, warehouses or other facilities whose entrance doors must be unlocked during the day and locked at night, as well as for emergency exit doors. When increased protection of the entry point is required, the electromechanical lock on the entrance door can be configured to operate in the NC mode.

An additional advantage of the ST-DB650MC model is the ability to mechanically unlock the electric lock using a key, which is available when it is operating in the NC mode. To do this, the electromechanical lock on the entrance door must be equipped with a Euro-standard cylinder (purchased separately). When implementing the so-called key access, the electronic control of the ST-DB650MC is also preserved: the bolt extends/retracts using a solenoid operating from a DC or AC source with a voltage of 12–24 V. At the same time, the lock stands out for its low power consumption (up to 300 mA) and heat generation.

The presence of the electromechanical lock deadbolt fixation monitoring line output ensures correct control of the ST-DB650MC state within the framework of access control systems. Using this output, you can track the moment when the locking deadbolt of the device will be aligned with the hole on the strike plate, so that the electromechanical lock on the entrance door does not block the deadbolt when holding the sash open, but only operates when the entrance door is completely closed. This operating principle of the ST-DB650MC allows you to avoid accidental or intentional damage to the deadbolt.
