What the TrueContact Magnetic Contact Sensor does
- Reports events. It sends a message when the state changes, so batteries last longer.
- Monitors openings. Doors, windows, cabinets and plant room panels are all covered.
- Installs quickly. Fix it to a frame or wall, or use adhesive where drilling is not allowed.
- Shows status. The LED confirms joining and operation during commissioning.
Where it is used
Plant rooms, electrical cabinets, riser doors, windows in conditioned spaces and storage areas in UAE and GCC offices, hotels, malls and campuses. An open window or a door left ajar wastes cooling, and a door log helps with access checks.
Works with BuildOT One
- FM360 raises tasks when an opening stays in the wrong state.
- Predictive Center uses event history to show patterns.
- Energy and Utilities links open windows to cooling waste.
