Abstract

A security and monitoring device for an emergency exit door has an electrical control device 15 with a microprocessor, an LED current-status display device 11, an emergency off switch device 3, and a key switch device 12 are located in use in a door terminal 20. In order to obtain an especially simple design as well as advantages in assembly and maintenance, provision is made that door terminal 20 is modular in design and control device 15, status display device 11, emergency off switch device 3, and key switch device 12 are designed as modules. These modules are located in under-plaster switch boxes so that an under-plaster arrangement of the terminal is obtained.

6. Security and monitoring device according to claim 1, wherein each of the under-plaster switch boxes can be mounted depressed in a fixed frame of the door or window system or in a wall that adjoins the door or window system.

7. Security and monitoring device according to claim 1, wherein an outer frame device is provided which, when the add-on module is in the under-plaster switch box, surrounds the add-on module and/or fits over the outer edge of the under-plaster switch box.

8. Security and monitoring device according to claim 7, wherein the outer frame device is designed as a common one-piece structural element associated with a plurality of under-plaster switch boxes.

9. A system according to claim 8, wherein an outer frame device is provided which, when the add-on module is in the under-plaster switch box, surrounds the add-on module and/or fits over the outer edge of the under-plaster switch box.

10. Security and monitoring device according to claim 1, wherein the electrical control device and the current-status display and the emergency off switch and the key switch device are designed as respective add-on modules for reception in an under-plaster switch box.

11. Security and monitoring device according to claim 1, wherein each the add-on modules has a main body which is essentially completely submerged in an associated under-plaster switch box when the module is inserted into the under-plaster switch box, whereby provision is made so that the main body is connectable, for example by a screw connection, with the under-plaster switch box and/or the adjoining fixed wall or the adjoining frame of the door or window system.

12.
