Emergency escape

The operator can be fitted with different emergency escape units to ensure a safe evacuation of the
building.

Break-out unit PSB

The door leaves and the side screens are swung outwards when a defined pressure is applied.
The break-out function can also be used to create a wider opening. From the fully swung out position,
the door leaves can be manually slid sideways, offering the possibility to transport wide objects
through the opening, or to make a shop entrance more inviting during good weather.

Electrical emergency unit

The door is opened by means of a rechargeable battery unit in the event of a power failure. The door
remains in this position until the power is restored. The operator will then resume the function set
by the programme selector. The emergency unit is monitored by the operator control unit. A mon-
itoring error means that the door opens and remains open until the error is cleared.
For further information, see General accessories on page 19.
The electrical emergency function can also be used to close the door in the event of power failure.
The fire authorities make this a requirement to stop fire or smoke from spreading throughout the
building.
