CELLAR VENTILLATION SYSTEM WITH AUTO DETECTION AND CONTROL

Abstract

CO based ventilation automation system, Auto Vent, is specially designed PLC based control unit or
programmable control unit for ventilation monitoring & control. It receive to signals from various gas detector
units, process the signals and generate control events based on pre-defined parameters. Based on pre-defined
logic, it will operates, regulate, stop-start axial / jet fans, alarm units, ventilation system – dampers etc. Auto Vent
system is designed on digital communication based programmable logic controller (PLC) system. Due to its
unique features, Auto Vent laying cost), but also on design, implementation, integration and maintenance. With its
advance feature, it can remotely control onboard potential free relays can fetch signals from as high as 96 detector
units, connected in daisy – chain fashion. Thus, this architecture not only save huge capital investment on system
installation (cable purchase cost, on detector unit, thereby remote triggering alarms / fan control etc. It also offers
signal readout of each detection units, fault recognition in the system, location of fault, location of alarm, in text as
well as graphical matter. Auto Vent is equipped with 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 fire signal. As well it can be connected to BMS System
