In an automated process to operate an emergency exit with a sliding door, the door drive has an electronic control unit linked to downward directed sensors that monitor the last fifth of the door travel. In normal operation the presence of an obstacle in this last sector results in immediate arrest or reversal of the door operation. The drive system is coupled to a house emergency system which if activated allows for the doors to open, but disallows closure in the event of an obstruction in the last one fifth of travel. |
