Expand installation at a VvE
Let the board or the competent administrator coordinate the order and access. Create a list of affected residences and common areas. Agree on how residents are informed about interruptions and who after delivery manages names, users and changes. For expand installation, we first discuss call routing, door release and user access with board of directors and residents. We first check the capacity, compatibility and free connections of the current system. A weak electrical lock or incorrect power supply causes more failures than the intercom post itself. We also consider how calls reach the right user and the door release has been tested together.
