We make sure they stay connected: every system on its own network, open to the people who maintain it and monitored like everything else we install. The building’s own team gets its IT looked after too.

We run the rack and watch it; the contractors keep running their systems.

The internet line comes in through it, a contractor’s session goes to the one device it is allowed to reach, and nothing on one network can see another.

Each one gets its own network, kept apart from the tenants, and the separate routers and switches every contractor used to bring along make way for one setup that we look after.

We give them their own 4G line, or a port on ours, kept apart from everything else in the building.

VoIP is not a replacement here: those devices rely on the tones and the power the copper line carried, and for an emergency line it is often not allowed. So we fit 4G gateways on our own SIMs that keep the existing handset working, on battery through a power cut. We coordinate with the lift company, the fire safety contractor and the landlord, so you are not the one passing messages between them. At Covent Garden in Brussels that meant 23 lifts, each with a plan of its own. ![Eight FlatTurtle simboxes with 4G antennas in the Covent Garden technical room](https://img.flatturtle.com/flatturtle.com/assets/covent-simboxes.jpg) ![A fire-alarm transmitter board with its own SIM card, fitted by FlatTurtle](https://img.flatturtle.com/flatturtle.com/assets/fire-alarm-transmitter-sim.jpg) ![Four wall-mounted battery modules and an inverter in a basement, connected over 4G by FlatTurtle](https://img.flatturtle.com/flatturtle.com/assets/battery-storage-basement.jpg) ![An outdoor battery storage cabinet in a car park, connected over 4G by FlatTurtle](https://img.flatturtle.com/flatturtle.com/assets/battery-storage-car-park.jpg) The simboxes at Covent Garden give every lift phone and fire panel its own mobile line, so the emergency call still gets out once the copper is gone. Next to them, a fire alarm transmitter on its own SIM and two battery installations we put on 4G. ## One network per system Each contractor reaches their own system, and nothing else. ### BMS and facility contractors We connect the building systems that Equans, Veolia and other maintenance contractors run. Each one gets its own network, kept apart from the tenants, and the separate routers and switches every contractor used to bring along make way for one setup that we look after. ### Cameras, intercoms and gates Camera recorders, the intercom at the front door, the barrier to the car park and the access control all sit on the network we run, each kept apart from the guests and from one another. ### Chargers, batteries and solar EV chargers, battery storage, solar inverters and sensors have to report home, and they tend to sit in a basement or a car park far from any network. We give them their own 4G line, or a port on ours, kept apart from everything else in the building. ### Remote access for contractors When a technician needs to reach a controller from outside, we open the way to that one device and nothing else, so a maintenance contract never becomes a way into the rest of the building’s network. Where the security rules are strict, the building systems can run on a network that never touches the occupier’s own. For an embassy in Brussels, the building management runs on an isolated 4G network with secure remote access, and not a metre of new cable was needed. Every system we connect is looked after the same way as our own equipment. [How monitoring and support work](https://flatturtle.com/monitoring-and-support). ## IT for the reception and the building team Most buildings are run by a small local team: a receptionist, a building manager, sometimes a technician, and nobody whose job is IT. We take that part on. The computers and the printer at the front desk, email and Microsoft 365, the software reception works in, a VoIP phone where one is needed, and the team’s mobile phones and SIMs are all set up, kept up to date and one number away when something has to change. ## It starts with a walk through your building. We spend an afternoon in your building and come back with what we’d install, what we’d leave alone and the monthly cost. Free, and no obligation.
