What is required for an additional manual actuator or operating device?

The requirement for an additional manual actuator or operating device to be placed near the exit and operable from ground level is crucial for safety and accessibility during an emergency. This positioning ensures that individuals can easily access and operate the system without having to navigate obstacles or reach high areas that may be difficult during stressful situations, such as a fire. By having the actuator at ground level near an exit, it maximizes the chances that occupants can quickly reach and use the device to activate the extinguishing system, thereby enhancing the overall effectiveness of the fire protection strategy.

The focus on accessibility is in line with safety standards aimed at ensuring that all occupants, regardless of height or physical ability, can effectively utilize fire safety equipment. This aspect emphasizes the importance of user-friendly design in emergency situations. Having the device in a convenient location can significantly improve response time during a fire incident.
