Illumination system controlling method for e.g. LED, involves detecting fire by smoke detector, sending alarm signal to bus line, receiving alarm signal by controller, and transmitting alarm instruction by controller
The method involves detecting fire by a smoke detector (13), and sending an alarm signal to a bus line (21) of an illumination system (A), where the illumination system is transferred from a normal operating condition to an alarm condition. The alarm signal is received by a controller (10), and an alarm instruction is transmitted by the controller. Operating devices (1) in the alarm condition are alternatingly changed between a switching-on condition and a switching-off condition or high and low brightness values. An independent claim is also included for an illumination system with an operating device for the operation of an illuminant.
