What is a single action station?

A single action station is defined by its requirement for just one step to activate. Typically, this means that the device can be engaged by simply pressing a button or pulling a lever, allowing for rapid response in an emergency situation. This design is particularly useful in scenarios where time is critical, such as fire alarms or emergency signaling systems.

Other options mention two steps or specific locations, which do not align with the fundamental characteristic of a single action station. The simplicity and immediacy of one-step activation are critical for ensuring that users can respond quickly and effectively during emergencies.
