Smartec ST-SL150NC and ST-SL160NC of a latch of the normal closed type

The line of the door locking Smartec brand devices for control systems of access was filled up with fall of 2015 of a latch of the normal closed ST-SL150NC and ST-SL160NC type which will unblock the door lock when giving on them of a power supply and blocked at its shutdown. New electromechanical latches are intended for work under control of the ACS, are used together with mechanical locks with a slanting crossbar and can unblock a door even in the presence of antiloading to 150 N. They "crash" into a door box to the place of a response part of the lock irrespective of the place of its arrangement, and for adjustment of a gap between a crossbar of the lock and a uvula of the electromechanical device, the uvula can be moved concerning the latch body.

Unlike ST-SL150NC, the latch of ST-SL160NC is equipped with the mechanical lever of a long unblocking which allows for a necessary time frame to disconnect her uvula that the door was in not locked status. In other words, electromechanical latches of ST-SL160NC give an opportunity to organize free access to premises, for example, in the hours intended for visitors without admission or in case of long shutdown of power supply. At return of the lever to home position these electromechanical models purchase functions of the locking device again, and the unblocking of a door becomes possible only using the button of an exit or a command from the ACS controller.

Latches of ST-SL150NC and ST-SL160NC are expected work with mechanical locks with a slanting crossbar and crash into a door box instead of a response part of the lock. Thanks to symmetric construction of the body, these electromechanical latches can be set on right-or left-side doors and also in horizontal position provided that a mechanical part of the lock is located not with a classical method, and in the upper or lower part of a door cloth. By the principle of work new electromechanical devices are normal closed therefore provide reliable blocking of the lock of a door in lack of power supply including at its emergency shutdown.

The fast unblocking of the lock in the presence of the antiloading putting pressure upon a latch uvula is one of advantages of new Smartec devices. As antiloading can arise because of deformation of a shutter or for other reasons, these electromechanical latches will serve longer than the analogs which do not have such function. So, during the work from the alternating current source of 12 V of ST-SL150NC and ST-SL160NC allow to unblock a door at antiloading value to 150 N, and receiving a power supply from a DC power source these electromechanical models provide a lock unblocking, only if antiloading does not exceed 10 N.

To quickly correct a gap between the blocking element of a latch and a crossbar of the lock, changing under the influence of temperature or eventually, original construction of a uvula of ST-SL150NC and ST-SL160NC which can be moved on 1-4 mm concerning the body allows. At the same time electromechanical latches do not change the mounting position in a doorframe. It is possible to change a gap at any time when ST-SL150NC/160NC are already set. It should be noted that electromechanical new products of Smartec can be used together with any dead locks of the standard size having a slanting crossbar.

Management of work of a latch can be organized from the controller of a control system of access of the building or the local ACS. Anyway state management of ST-SL150NC and ST-SL160NC requires their connection to the centralized ACS or to the controller having the reader in the construction. For a door lock unblocking at an exit from the secure facility electromechanical latches of Smartec allow to use the exit button connected to their relay contact or the falevy handle using which it is possible to open a door from within the premises even in that case when on the electromechanical device power supply because of failure in network does not arrive.
