Which system does not require an intersystem bonding termination?

In the context of grounding and bonding, an intersystem bonding termination (IBT) is essential for providing a common ground point for multiple systems to prevent differences in ground potential that could lead to electrical hazards or equipment damage. Fire alarm systems do not require an intersystem bonding termination because they are typically designed to operate independently of other systems and do not share ground paths with communication or data systems. Their grounding is solely for the purpose of protecting the alarm circuitry and ensuring reliable operation without the need to bond to other types of systems.

In contrast, television antenna systems, grounding electrode systems, and data communication systems are all interconnected with other electrical systems and benefit from intersystem bonding to mitigate the risk of surges and to enhance overall safety. Therefore, the fire alarm system stands out as the single system that does not necessitate an intersystem bonding termination.
