Custom-made Controller E.D.&A. Regulates Ventilation Valves in Case of Fire

The world leader in building efficiency came to E.D.&A. for the development of a controller specifically for the ventilation in large buildings. This client provides products and services that optimize energy use and improve comfort and safety in buildings. In this context we can consider air conditioning, central heating, fire detection, etc.

In case of fire in these buildings we must make sure we prevent that ventilation systems fan the flames. All registers should be closed from one central computer system. This computer system receives alarms from the fire detection system. E.D.&A. is about to develop a controller to open/close the ventilation valves. All controllers have to be connected in one network with the central computer system.


o I/O:

o Digital inputs 8

o Relay outputs 4

o Local or remote control of ventilation valves

o Bi-coloured LEDs as status indication for fire valves

o RS485 network possibilities

o Power supply 230V

o Custom-made PCB for housing

o Green housing PVC, UL94-V0, IP20

Diverse applications

Through the wide experience in developing customer specific controllers for diverse applications (such as ventilation systems, bakery machines, water treatment installations, firescreens, etc.), technological knowledge can very easily be applied to a new controller design.
