Smart Building

A building is smart when systems and components are networked with each other so that processes can be controlled digitally.

Modern, intelligent buildings are mostly automated, energy-efficient, supply decentrally generated energy and are controllable in terms of electricity and heat use. Existing buildings can also become smart buildings as part of modernization and refurbishment projects.

We give energy efficiency the right beat

Our products can be found in a wide variety of designs in every smart building and ensure the function of the control and measurement instruments installed in them. Smart buildings supply decentrally generated energy and can be precisely controlled in terms of their consumption. In this way, we at GEYER Electronic are making our contribution to the big picture with the smallest components: the energy turnaround through greater energy efficiency.

Whether electricity meter or elevator – we supply precise frequency products for smart buildings

The talking refrigerator that reports missing food to the smartphone or the automatic sunrise through controllable blinds are just two small examples of the large field of smart building.

We produce frequency products for

  • Electricity- Water- Gas meter
  • Lighting controls
  • Access controls
  • Heating controls
  • Smoke detectors
  • Elevators
  • Shutter controls
  • Alarm and fire detection systems
  • Garage door controls

Our products can be found in actuators and controllers for

  • Air conditioners / heat pumps
  • Pumps
  • Memory boards
  • Valves
  • Ventilation
  • Switches

… as well as in intelligent data transmission systems (digital BUS systems)

  • KNX, LONWorks, DALI
  • SMI, MP-Bus, M-Bus
  • LORA/LORA WAN
  • EnOcean

Application examples from practice
