Abstract
A testing device for hazard alarm systems, particularly fire alarm systems, having a hazard alarm control panel connected with a variety of devices via a device loop configured as a ring bus system, and has at least one communication circuit for communication with the individual devices. The communication circuit comprises multiple functional units. The current measurement unit is checked and monitored by a device simulation unit that is completely integrated into the communication circuit and is controlled by a control unit configured as a microcontroller.
