What is the activation method for the fire pump NOT mentioned?

In the context of fire pump activation methods, each option presents a valid way the fire pump can be activated, except for the one specified.

Locally at the pump house is a traditional method where personnel can manually activate the fire pump at its location. This is a common approach found in many fire protection systems.

Remotely via MCMS (Motor Control Management System) indicates a more advanced method of pump activation that allows for control from a distance, which is increasingly common in modern fire safety systems.

The pushbutton on the DC deck represents another widely recognized activation method, where a dedicated button is used to initiate the pump from a control panel.

The reason the activation method through a pressure sensor is not mentioned here is because pressure sensors are typically used for monitoring purposes rather than directly triggering the fire pump. They can indicate when pressure drops below a certain threshold, prompting the pump to activate, but they do not serve as a direct activation method in the way the other options do. The function of pressure sensors is to provide feedback on system status rather than initiate action independently without another mechanism involved.
