Abstract: Alarm installations in buildings or other environments are used to notify people of particular events, particularly hazards. By way of example, fire alarm installations usually have visual signal generators which, in the event of an alert, bring a hazard situation to the attention of people in a building by means of visual signals. In this case, the aim is to use the visual signals to prompt the people to leave the building via the escape routes. A signal apparatus (1) for an alarm installation (2) is proposed, having a signal generator (3) for outputting a notification signal (6) to the environment of the signal apparatus (1), having a control device (4) for actuating the signal generator (3), and having an activation interface (5) for receiving an activation signal for triggering and/or synchronizing the control apparatus (1), wherein the activation interface (5) is designed to receive a notification signal (6) from a different signal generator than the activation signal.

Abstract: An imaging fire detector is used to detect a fire from a recorded image sequence. Either a video camera or an infrared camera is used as an imaging device. Characterizing parameters of a fire are either analyzed individually or in combination. In order to detect changes, an object analysis, a pattern analysis or a spatial-frequency analysis of the recorded image sequences is conducted. Using a threshold value for the duration of the changes, short-term changes are detected and discarded. In a further embodiment, the fire detector may also be used as a burglar alarm. With the aid of communication means, the fire detector transmits a fire alert to a master station.
