What is the HFT of QMR system?
What is the HFT of QMR system? Comapre QMR with TMR??

Hi Experts,

Please Is QMR (2OO4D) Safety System (like Honeywell SM System) considered having HFT of 1 or 2? Is this system actually more safe and available than TMR system (Triconex)? based on what I select QMR or TMR if both are achieving SIL-3?
