FIRE SPRINKLER FLOW SWITCHES & TEST SOLENOID TEST.

Описание к видео FIRE SPRINKLER FLOW SWITCHES & TEST SOLENOID TEST.

In Australia, we have to test all flow switches and test solenoids every six months to comply. The solenoids must activate & stop. The flow switch must send flow signal to the fire indicating panel... then to EWIS to start the evacuation process.
