Final answer:
A clogged inlet may prevent a pop-off alarm from sounding, depending on the system design and alarm's configuration.
Step-by-step explanation:
Whether a clogged inlet would prevent a pop-off alarm from sounding depends on the specific design and function of the system in question. Pop-off alarms are designed to release pressure and sound an alarm when pressure exceeds a preset limit, but a clog could prevent the system from reaching the required pressure. Generally speaking, pop-off alarms, also known as pressure relief valves, are safety devices that release pressure from equipment when the internal pressure exceeds a preset limit. They are commonly used in pressurized systems like boilers, air compressors, and chemical plants. If the inlet is clogged, this could potentially prevent the system from reaching the pressure required to activate the alarm.
It is crucial to identify the type of system and the alarm's configuration to determine the exact impact of a clogged inlet on the alarm's functionality.
