1. An aspirating smoke detector device, comprising:
a blower to draw gas into the aspirating smoke detector device for a flow condition testing procedure for a pipe sampling network, wherein the aspirating smoke detector device is connected to the pipe sampling network;
a sensor;
a memory; and
a processor configured to execute executable instructions stored in the memory to:
determine, via the sensor, a volumetric flow rate of the gas into the aspirating smoke detector device;
compare the volumetric flow rate of the gas to a threshold flow rate;
determine, in response to the volumetric flow rate of the gas being above the threshold flow rate, a flow condition to be a bad flow condition, wherein the bad flow condition indicates a leak existing in the pipe sampling network;
determine, in response to the volumetric flow rate of the gas being below the threshold flow rate for at least a predetermined period of time after initiation of the flow condition testing procedure such that a low-pressure condition forms in the pipe sampling network, the flow condition to be a good flow condition; and
cause the flow condition to be displayed.
