Final answer:
Building control circuit wiring powered and controlled by the fire alarm system is governed by building codes, including the installation of smoke detectors and proper electrical wiring.
Step-by-step explanation:
Building control circuit wiring that is both powered and controlled by the fire alarm system is governed by building codes. These codes are put in place to ensure the safety of the building's inhabitants and require proper installation of electrical wiring.
In many MDCs, building codes stipulate the installation of smoke detectors as a safety requirement. This ensures early detection of fires and prompt evacuation, minimizing the risk of injuries or fatalities.
The building codes also require properly installed electrical wiring to prevent electrical hazards such as short circuits or electrical fires. By complying with these codes, buildings can ensure the safety and well-being of their occupants.
