Shall movement of water, waste surges, or variable pressure initiate an alarm?

In fire alarm systems, the initiation of an alarm due to movement of water, waste surges, or variable pressure is generally not permitted as a standard practice. This is based on the principle that alarms should be triggered by specific, unambiguous conditions indicative of a fire or emergency situation.

Movement of water or other similar factors can often occur in everyday scenarios, such as in plumbing systems or during rainstorms, and could lead to false alarms if they were to initiate an alarm. Therefore, the approach typically accepted is to avoid false triggers and only initiate alarms based on clear indicators of a threat, such as smoke detectors detecting particles or heat detectors responding to increased temperatures.

The correct stance is that these conditions should not self-initiate alarms unless there is a direct correlation with fire detection that is being actively monitored. This ensures that the alarm system remains reliable and functions effectively in true emergency situations.
