How the air release from pipeline once detection detect and sprinkler not burst

[@irfancfps]

Air will release whenever sprinkler breaks

[@kavinarthick8281]

⁠when detection detects .. sprinkler not burst . Water want to enter into pipeline but it was filled with air so due to air water cannot enter into the pipeline.. in this stage how stage how air get release

[@BenSchultz-v6y]

Water will still enter the piping when the detection activates (this releases the solenoid to vent priming water). There will still be air but the system will start filling with water. Supervisory approval is normally around 10 PSI. The water will compress the air until the pressures equalize but the alarms will have activated by this point.
