What are the two basic requirements for electric drivers?

Adequate electrical input and vent represent the fundamental needs for electric drivers in sprinkler systems. Electric drivers require a sufficient electrical supply to operate efficiently, ensuring that the sprinkler system functions correctly when activated. Additionally, the provision of ventilation is crucial as it helps to dissipate heat generated by the electric driver during operation. Proper ventilation prevents overheating, which could lead to malfunctions or failures in the system.

The other options do not address the essential operational needs of electric drivers. Options concerning compliance with NFPA standards focus on broader regulatory requirements rather than the specific operational requirements needed for electric drivers. Similarly, considerations about light loads and protective guards relate to equipment design and safety but do not capture the core requirements for functionality of electric drivers as effectively as the need for adequate electrical input and ventilation does.
