A method for signaling an escape route in a building with emergency warning units arranged in a distributed way can be realized such that the emergency warning units are equipped with luminous means that in the event of an emergency can be activated by a central emergency warning system sequentially in the manner of a running light that designates the direction of the escape route leading away from a hazard site. An emergency warning unit suitable for this purpose may include two LEDs configured as arrows facing in opposite directions, of which either can be switched into a blinking mode by the central emergency warning system in accordance with the emergency conditions.

Method and apparatus for marking an escape route

A contact element suitable for SMD printed circuit boards is made of a flexible blank of sheet metal of approximate C-shaped cross-sectional configuration, with dimensions of a DIL package for SMD integrated circuits. The contact element is provided with bent terminals which are soldered onto respective bonding pads upon the circuit board while the top surface of the contact element is provided for contacting by a resilient external countercontact.
