A safety system for sliding elevator doors (1) is disclosed. The system comprises a sliding door panel (2) and a door frame (3), or two sliding door panels (2) moveable in the same direction with different speeds. The system is characterized in further comprises a force-sensing resistor (4) extending along a side (5) of the door frame (3) facing the door panel (2), or along a side (6) of the slower-moving door panel (2b) facing the faster-moving door panel (2a), for detecting an object between the door panel (2) and the door frame. The system is further characterized in that movement of the door panel (2) is configured to be stopped when a characteristic, such as force, or speed of change in the force exerted on the force-sensing resistor, exceeding a predetermined threshold value is detected by the force-sensing resistor (4). Also an elevator, a door frame, a door panel and a method of installing said system are disclosed.
