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.
