فيديو شرح Wiring Switches - Waterflows and Tampers ضمن كورس انظمة انذار الحرائق شرح قناة Pyrotex Systems، الفديو رقم 5 مجانى معتمد اونلاين
We get to take a good look at the wiring for a Potter OSYSU-2 switch for a sprinkler tamper valve, and a Potter VSR type waerflow switch. Here we discuss how to use a monitor module to supervise a valve for a supervisory signal, how to use a monitor module to supervise a waterflow switch for alarm, and how control a flow bell using the terminals of the waterflow switch.
