Hi Thanks for your knowledge sharing.. can you please make hand sketch flow chart will be helpful and what level carbon monoxide Wil triggering if we have any specific range pls share details

[@sennapparajan.p]

Hi.. the level is based on our setting in PLC. we can set any level for triggering by PLC programming. example.. 0-20 PPM level is normal if CO level goes above 20PPm we can start the FAN and extract it. hope u got an idea.

Which instrument detects fire in parking area?

[@sennapparajan.p]

there are two devices that detects fire. 1.smoke detector which is connected to fire alarm panel 2.corbon monoxide sensor which is connected to plc panel (basement ventilation panel) This panel also connected with fire alarm panel (fire alarm input )
