Why does the Fenwal fire detection system use spot detectors wired parallel between two separate circuits?

To increase sensitivity
To decrease power consumption
A short may exist in either circuit without causing a false fire warning
To make the system more affordable

The correct answer is: A short may exist in either circuit without causing a false fire warning

The reason why the Fenwal fire detection system uses spot detectors wired parallel between two separate circuits is to ensure that a short in either circuit will not cause a false fire warning. This is because if one circuit experiences a short, the other circuit will still be able to detect the fire and trigger the alarm. Choosing option A, B, or D would not provide this level of safety and reliability as a short in either circuit could potentially lead to false fire warnings. It is also important to note that Fenwal is a highly reputable brand and prioritizes safety and effectiveness in their fire detection systems. So, it is unlikely that they would sacrifice these factors to simply decrease power consumption, make the system more affordable, or increase sensitivity.
