Commissioning of Combined AOV & Access Door

Commissioning of Combined AOV & Access Door

Where access is required to the roof from the escape stair, a combined AOV and Access Door is utilised. Compliant to EN12101-2 the door remains locked for security purposes and opens when activated by the smoke extraction controls system. A key switch located at the head of the stair, linked to the smoke ventilation controls system provides maintenance access whilst negating access for non-authorised personnel.
