What is a common requirement for the primary power supply of fire alarm systems?

The requirement for the primary power supply of fire alarm systems to meet specific voltage requirements is essential for the system's reliable operation. Fire alarm systems are designed to function under precise electrical conditions, ensuring that they can detect smoke, heat, and other indicators of fire without failure.

Different types of fire alarm systems may have different voltage requirements; for instance, most systems operate on low voltage, typically between 24 volts DC. Meeting these voltage standards is crucial not only for the functionality of the devices but also for ensuring the overall safety of the building. If the power supply does not meet the specified voltage, components may not operate correctly, which could lead to a failure in alerting occupants or notifying emergency services in the event of a fire.

Additionally, having the power supply meet specific voltage requirements helps to prevent issues such as overheating or damage to the alarm components, contributing to the overall longevity and reliability of the system. Safety standards and codes typically dictate these voltage requirements, which must be adhered to in order to pass inspections and certifications necessary for operation.
