When it comes to bonding and grounding electrical components to a fire sprinkler system, what is not allowed on a fire sprinkler system?

In the context of fire sprinkler systems, grounding refers to the practice of connecting a metal part of the system to the earth to provide a path for electrical fault currents. However, grounding is not permitted in the fire sprinkler system itself because it can create a corrosive environment, leading to degradation of the piping and components. Electric current can cause electrolysis in metal pipes, which can ultimately lead to leaks and failures in the sprinkler system.

On the other hand, bonding, which is the process of connecting two or more conductive objects together to ensure that they have the same electrical potential, is permitted. This is essential for preventing potential differences that could create hazards. Therefore, while bonding is allowed and necessary for safety and functionality, grounding is not suitable for fire sprinkler systems due to the risks it poses to the integrity of the system.
