Fermax 1781 MECHANISM 540AAD MAX

There are several types of lock release mechanisms, it depends on the TYPE OF OPERATION that is needed.

TYPE Aa_AUTOMATIC_INVISIBLE 12Vac:

• Aa (Invisible Automatic Operation and activation at 12 Vac): the lock release automatically unlocks when it receives a 12Vac voltage impulse. The lock release locks again once the power is no longer supplied and the door opens and closes mechanically. It is indicated that it is invisible since it does not have the normal pin of the Automatic lock release.

The electric MECHANISM is a device that is installed in the door frame to control its opening from a remote location using an electrical device. In an electronic door entry installation, it is possible to activate the building entrance mechanism and allow visitor access from the home's telephone or monitor by pressing the door opener 'key' button. A lock release is made up of an electrical mechanism and an armor or cover depending on whether it is built-in or surface-mounted.
