Signal device for an alarm system, alarm system, and method for operating the signaling device

Alarm systems in buildings and other environments are designed to point people to special events, in particular hazards. For example, have fire alarm systems the usual way via optical signal transmitter, which draw attention at alerting people in a building on a dangerous situation by optical signals. The goal is to get the people through the optical signals to leave the building via the escape routes. There will be a signaling device 1 for a detection system 2, a signal generator 3 for outputting a strobe signal 6 in the vicinity of the signal apparatus 1, with a control device 4 for controlling the signal generator 3, and with an activation interface 5 for receiving an activation signal for triggering and / or synchronization of the control apparatus 1, proposed wherein the activation interface 5 is designed for receiving a strobe signal 6 from another signal transmitter as the activation signal.
