Window actuators directly integrable into BMS
More and more modern buildings are controlled by a BMS application – Building Management System.
The system includes hardware and software components designed to monitor and control a wide range of parameters and processes involved in building operation, related to:
- Building climate control (heating in winter and cooling in summer);
- Indoor Air Quality (I.A.Q. – Indoor Air Quality);
- Interior and exterior lighting (architectural);
- Monitoring and security systems;
- Passive and active fire protection systems.
These building automation systems monitor and control dozens or even hundreds of sensors, cameras, and peripheral equipment with various functions.
Automated natural ventilation systems, based on window actuators, are increasingly in demand, especially in “green” buildings (Green Buildings), due to the multiple benefits offered (more details in the article dedicated to automated natural ventilation of buildings).
Operation of the System with Intelligent Window Actuators
Assuming we have 11 actuators on a floor of an office building, bidirectional communication with the BMS system allows, for example, actuator 101 to be opened 60%, actuators 102 and 103 opened only 10%, actuator 104 opened 100% because 105 signals an opening error, and actuators 109, 110, and 111 to be completely closed. Actuator 108 could be used for smoke extraction, being commanded to open 100%, at maximum speed, in case of a fire alarm.

Benefits of Intelligent Window Actuators
To meet the specific requirements of modern buildings, KADRA offers you a range of intelligent window actuators – the new generation of actuators directly integrable into any Building Management System.
Unlike classic actuators, which can only receive an open or close command and move as long as they are powered by electricity, BMS Line actuators have an integrated control module and communicate bidirectionally with the Building Management System.

Here are the concrete advantages of these motors for windows directly integrable into BMS:
- total control plus interaction and communication with the other systems controlled by BMS (air conditioning, lighting, etc.);
- no additional control modules are required;
- each actuator has its own identity (unique IP address) and can be addressed independently;
- permanent bidirectional communication, with real-time feedback (position, error signalling, etc.);
- the window can also be controlled via a locally installed button;
- smoke extraction control units are integrated directly;
- for ventilation they can operate silently, at reduced speed, and for smoke extraction they open to maximum stroke and at maximum speed;
- they are 100% compatible with ANY BMS protocol (Modbus RTU, KNX, BACnet, Lonworks etc.).
The intelligent window actuators proposed by KADRA are state-of-the-art and are suitable for any type of buildings controlled by a Building Management System: office buildings, supermarkets and shopping centres, public institutions, kindergartens, schools, secondary and higher education institutions, etc. These automations integrate directly into BMS, can be added at any time, have a unique network address and can be controlled independently, and for the building owner and users they are a beneficial upgrade, in terms of reducing operating costs, air quality, increasing work productivity, etc.
