Fire alarm systems must be installed, tested, and maintained according to what guideline?

The guideline that fire alarm systems must be installed, tested, and maintained according to is the manufacturer's instructions. This is crucial because the manufacturer provides specific guidelines based on the design and functionality of their equipment. Following these instructions ensures that the system operates as intended, providing reliable warning and response in case of a fire.

Manufacturer's instructions include critical information regarding installation procedures, required testing methods, and maintenance schedules that are tailored to the specific components of the system. Adhering to these guidelines helps in maintaining compliance with safety standards and regulations, ultimately contributing to the effectiveness of the fire alarm system in protecting lives and property.

While the authority having jurisdiction might set the codes and standards for fire safety, it is the manufacturer's specifications that provide the detailed operational framework necessary for individual systems. Engineered drawings and the direction from the building owner can support the implementation but do not carry the weight of the specified technical requirements that manufacturers give for their devices.
