The easiest way for security. An electric motor automatically locks the door when the door is closed by automatic locking of its two hooks and main deadbolt – secure and firmly sealed. The door is unlocked using a remote control or another contactless electronic access system such as Bluetooth; or biometric devices like fingerprint reader or retina scanner for enhanced security. It`s also quick and easy from the inside – using a button or door handle, or using an intercom. Flexibility via day mode (door is closed but not locked) and night mode (door is locked automatically) at the press of a button increases the comfort produced by the system. In emergency cases, when there is power failure, keyless solutions permit manual opening with a key from the outside.
