Richard Posted October 5, 2017 Report Share Posted October 5, 2017 On a building entrance that has auto sliding doors and which open on fire alarm activation and mains failure with also a staff key override is a green box manual emergency override required. I see some premises with them and others not. In this particular the main entrance doors opened on approach. The rear staff entrance doors do not as it is only accessed by staff fob key. Neither had a green box installed on the escape side. Thanks. Quote Link to comment Share on other sites More sharing options...
Tom Sutton Posted October 7, 2017 Report Share Posted October 7, 2017 Sliding doors and magnetic locked doors on escape routes should meet the standards of BS 7273 part 4 which requires a manual override switch (green MCP) to open the doors if required in an evacuation, with some exception like places of lawful detention but retail premises are not one of them.
