Wet pipe sprinkler systems principle Schema

When the sprinklers blows (1), water take open the clack (2) and water goes the trim set (3) for alarm. After that direction water goes retarding chamber (4), in retarding chamber by the pressure switch (6) systems get alarmed. Than gong gives water and mechanical alarm are ringing. (5).
