Every access-controlled door that is operated from the outside by a credential reader, keypad, or intercom must also have an exit button on the inside face, allowing occupants of the building to leave freely without needing to present a credential from inside. This is a fundamental requirement of any door access control installation: the access control system manages who can enter, not who can exit, and exit must always be available to occupants.
The ACC-EX01 provides this exit request function in a square polycarbonate format. Polycarbonate is a thermoplastic with significantly higher heat resistance than standard ABS plastic, which is relevant for exit button applications because fire safety regulations may require electrical accessories at fire door positions to meet specific fire resistance standards. The fireproof PC construction addresses this requirement.
The button operates in the normally open configuration: pressing the button momentarily closes the circuit, releasing the electric lock or latching device on the door and allowing it to open. The circuit returns to normally open when the button is released, and the lock re-engages when the door closes.
For access control engineers completing door system installations on fire doors and controlled access points across commercial buildings, offices, and public-facing premises in London and the UK, the ACC-EX01 provides a compliant, professional exit button specification in fireproof polycarbonate.
