How should alarm circuits be configured when hazardous materials are stored?

When dealing with alarm circuits in the context of storing hazardous materials, the priority is the safety and integrity of the alarm system. Isolating alarm circuits from other circuits is crucial to ensure that potential interference or faults do not compromise the function of the alarm. This configuration helps maintain the reliability and responsiveness of the alarm, even in the presence of hazardous materials that may produce conditions suitable for fire or chemical exposure.

This isolation ensures that if a fault occurs in a non-hazardous circuit, it won't impact the operation of the alarm circuits, which are critical in alerting personnel to dangerous situations. Additionally, maintaining this separation aligns with safety standards and regulations that are designed to protect both the facility and its personnel from risks associated with hazardous materials.
