Are visual signaling requirements necessary for "FIRE RECALL" switches?

Visual signaling requirements for "FIRE RECALL" switches are not mandated as part of the standard regulatory requisites. The reasoning behind this is that the primary function of the "FIRE RECALL" system is to ensure safety during fire emergencies, allowing elevators to respond appropriately to fire conditions by returning to a designated level, typically the ground floor, and making them inoperative to prevent them from being used in a potentially hazardous situation.

In this context, audible signaling may be sufficient to alert individuals within the vicinity of the elevator system regarding its status, particularly since the focus during a fire emergency is on timely and effective communication through sound. Therefore, visual signals are not deemed as a necessary requirement for "FIRE RECALL" operations, which prioritizes the operational effectiveness and safety protocol over additional visual alerts.

This understanding aligns with safety regulations that aim to maintain simplicity and efficacy during emergency scenarios without imposing additional visual signaling requirements that might complicate or confuse the emergency procedures in place.
