This is a specialised control unit for managing emergency doors in environments where the emergency exit is a critical point for intrusion and burglary protection (bank branches, supermarkets,etc.).
It controls the holding force of the electromagnet to prevent accidental opening and generates the appropriate alarms on unauthorised opening. It manages the buttons to release the door immediately in the event of an emergency. Authorised opening is made possible by the use of electronic keys, which can be programmed for service opening or timed entry.
It can also operate with a BUS connection to a PB alarm control unit to become an integral part of the security system.
