Visualisation of the operation of elevators and escalators

We use the Lemon and Sokolík systems for remote monitoring and visualisation of elevators and escalators. Thanks to them, the customer has access to continuous information about the operation of the equipment and its status.


Lemon is a new monitoring system for elevators and escalators in large buildings. What does it provide?

  • current overview of the operability of all elevators/escalators
  • elevator reservation for emergencies
  • lower costs for technical supervision of equipment
  • faster intervention of technical personnel in the event of a malfunction
  • regular UV disinfection


The Sokolík universal remote monitoring system uses a GPRS data connection and is primarily intended for basic monitoring of elevators and escalators. The device can be installed in two ways:

  • directly into the switchboard (without 12 V DC power supply and backup power supply)
  • including a separate cabinet with monitoring equipment, mains and backup power supply

Basic assembly Sokolík 4 without switchboard (4 inputs)

For simple, inexpensive monitoring of these basic device states:

  • default
  • service
  • power outage
  • emergency signalling
  • in the case of an escalator, ride up, ride down
  • safety circuit failure, voltage failure

The Lemon system takes care of the visualisation.

Basic assembly Sokolík 16 without switchboard (16 inputs)

For more demanding applications with monitoring the operation of the given device:

  • default
  • service
  • power outage
  • emergency signalling
  • door status
  • cabin position

The visualisation is performed by the Lemon monitoring system.

Connecting the Sokolík system to the monitored device

The Sokolík system is connected by means of 4 to 16 visually discrete 12-24 V sensing inputs, which are connected to the monitored technology. When there is a change on any input, the device sends a data message to the monitoring server for further processing, e.g. by Lemon software.

The parameters are set using SMS messages, in the same way you can get information about the status of the device, signal strength, voltage of the backup source, etc.

Method of delivery of the Sokolík system 4/16

We deliver the device in a sheet metal distribution box with dimensions of approx. 300 x 400 mm with IP 20 protection for escalators. On special request, we can also supply you with a version in a switchboard with IP 64 protection.

You can learn more about the delivery composition of the Sokolík module and the Lemon system from our product sheets.

Monitoring of elevators

We use an application accessible via the Internet to monitor the reliability and safety of elevator operation and to analyse it remotely.

Elevator controls

Wall-mounted cabin panels, full-cabin panels, callers and position signalling with an emphasis on reliability, design and sufficient colour variability.

Automatic UV disinfection of the elevator

Expert information on the UV-Cab device for the safe disinfection of elevator cabins from viruses and bacteria with adjustable automatic operation.


The new REVYT recuperation unit, which can be installed on almost any type of elevator, contributes to reducing energy consumption and operating costs.
