Working Principle:

CO Car Park Auto-Ventilation Automation System is specially designed PLC based control unit or programmable control unit for ventilation monitoring & control. It receives signals from various gas detector units, processes and generates control events based on pre-defined parameters. Based on pre-defined logic, it will operate, regulate, stop-start axial / jet fans, alarm units, ventilation system – Fire dampers etc.

Our system is designed on Analog/Digital communication based programmable logic controller (PLC) system. Due to its unique features, we can fetch signals from as high as 256 detector units, connected in 2-wire fashion. Thus, this architecture not only saves huge capital investment on system installation (cable purchase cost, laying cost), but also on design, implementation, integration and maintenance.

With its advanced feature, it can remotely control onboard potential free relays on detector unit, thereby remote triggering the Exhaust Fans/Alarms / Axial fan control etc.

It also offers signal readout of each detection units 24/7, fault recognition in the system, location of fault, location of alarm, in text as well as graphical manner via a Full LCD 7-inch screen. our system is equipped with a colored LCD display, thus offering onsite user friendly control and system configuration.

With its inbuilt digital output, it can be integrated with fire alarm system to generate a fire signal.
