inform sb to do sth vs prevent sb to do sth

Some examples from the web:

• In that regard, the reference by SBS to the Essent Netwerks case is not relevant.
• Indeed, the investigation showed that the cooperating companies sold 75 % of their production of SBS to well-established third country markets.
• These signals are transmitted to the flow controller FC2 that controls either the pressure blower PB or the suction blower SB to maintain the desired exhaust split and dilution ratio in DT.
• This signal is transmitted to the flow controller FC1 that controls the suction blower SB to maintain a differential pressure of zero at the tip of the probe.
• adjusting the suction blower SB to a constant mass flow of the diluted exhaust gas and controlling the flow of the pressure blower PB, and therefore the exhaust sample flow in a region at the end of the transfer tube TT (Figure 12).
