Electric strikes are the most widespread solution for electric door locking, thanks to their versatility in being suitable for almost any type of door. DORCAS is a Spanish manufacturer with an extremely wide range of products, offering high-quality electric locks. A DORCAS-77 series is the DORCAS large-sized electric locks that can safely open when subjected to a pressure of 450 kg on the door. Thanks to this, they can even be installed in escape routes. The device operates in a fail-safe mode, meaning it requires power to be locked. DORCAS electric strikes should always be installed indoors, in a place well protected from rain. If you are looking for an electric strike suitable for outdoor installation, the waterproof series models are the right choice. This product is suitable for left-handed doors. For right-handed doors, choose the DORCAS-77-NF-512-R model. MAINTENANCE! Regular inspection of the mechanics of electric strikes (refreshing lubrication) is necessary to ensure optimal operation. |
