Safety device for an elevator system or escalator system, elevator system, and method for indicating the status of a safety circuit

A safety device for use with a system being an elevator system or an escalator system, the safety device comprising:

• a safety circuit including a plurality of safety circuit elements that are normally closed during an operation of the system, wherein the safety circuit is adapted for stopping the operation of the system when at least one of the safety circuit elements opens;
• a manual service switch for opening at least one of the safety circuit elements;
• and
• a light device adapted to be illuminated in a first illumination color while all of the safety circuit elements are closed and is adapted to be no longer illuminated in the first illumination color when at least one of the safety circuit elements is open.

A method for indicating a status of a safety circuit of a safety device for use with a system being an elevator system or an escalator system, wherein the safety circuit includes a plurality of safety circuit elements connected in series and a manual service switch for opening at least one of the safety circuit elements, the method comprising the steps of:

• providing a light device;
• illuminating the light device in a first illumination color when all of the safety circuit elements are closed;
• and
• changing the illumination color of the light device from the first illumination color when at least one of the safety circuit elements is opened by operation of the manual service switch.
