Question

VENTILATION PANEL: What happens when either BLOWER or EXTRACT pushbuttons are in OVRD?

A) The ventilation system is turned off
B) The ventilation system operates in normal mode
C) The ventilation system operates at maximum capacity
D) The ventilation system goes into standby mode

Answer 1

With the BLOWER or EXTRACT pushbuttons set to OVRD on a ventilation panel, the ventilation system operates at its maximum capacity to provide increased airflow for specific or emergency needs.

Step-by-step explanation:

When either the BLOWER or EXTRACT pushbuttons on a ventilation panel are set to OVRD (over-ride mode), option C) The ventilation system operates at maximum capacity is the correct answer. This means the system will bypass normal operational constraints and work at its highest capability, typically to provide increased airflow due to specific requirements or emergency situations. By operating at maximum capacity, it can help clear smoke in case of a fire or introduce more fresh air into the environment rapidly.
