What is a requirement for the installation of initiating devices in fire alarm systems?

The requirement that initiating devices in fire alarm systems need independent support from circuit conductors is critical for ensuring the reliability and integrity of the fire alarm system. This means that the initiating devices, such as smoke detectors or pull stations, should not solely rely on the circuitry for support; they must have their own structural reinforcement. This is important to prevent any potential failures that could arise if the supporting circuits were damaged or compromised during a fire event or due to other environmental factors.

The independence of support allows the initiating devices to remain operational and effectively communicate with the fire alarm control panel, ensuring timely detection of fire conditions and activation of alarms. This requirement helps comply with safety standards and enhances the overall functionality of the fire alarm system in protecting lives and property.
