How to implement an interlock function that opens the interior and exterior doors in case of explosion protection?
Thread Content
As required by the specifications, the interior and exterior doors of the blast-resistant control room must have an interlock function that ensures they open when not in use. How is this function implemented in practice?
It involves adding a control circuit to achieve door locking, ensuring that the two doors cannot be opened simultaneously under normal conditions. Many manufacturers of blast-resistant doors have corresponding solutions, and these solutions offer comprehensive functionality
The inner door and outer door are interlocked: if the inner door is opened, it does not close, and the outer door cannot be opened; if the outer door is opened, it does not close, and the inner door cannot be opened. There are high-end options as well as lower-cost ones; the manufacturer has all of them available for consultation.
