A critical feature of a fire sprinkler system is its automatic activation from heat. This capability is essential because it allows the system to respond quickly and effectively to a fire without requiring any manual intervention. Sprinklers are designed to detect the rise in temperature caused by fire, and they activate automatically based on predetermined temperature thresholds. This swift action helps control or extinguish the fire, minimizing damage and increasing safety for occupants.

While manual activation, an immediate water supply, and wireless connectivity can be important aspects of broader fire protection strategies, they are not as central to the fundamental operation of fire sprinkler systems as automatic activation. Automatic activation ensures that the sprinkler system can function effectively in an emergency, even in scenarios where occupants may not be able to react quickly. This feature is vital for ensuring that the sprinkler system can provide timely intervention at the onset of a fire.
