Pressure operated AC B100012

Description

The pressure operated switch uses the pressure of the discharging agent for activation and must be connected to the distribution piping. The agent actuates a pressure operated stem which toggles the electrical switch. Each switch can also be operated manually by pulling up on the stem. These switches are used to annunciate alarms, shut down ventilation, and turn on electrical automatic
dampers or other electrical equipment. Each pressure switch must be manually reset, by pushing down on the stem to return the switch to the set position. The minimum operating pressure required is 50 PSI. The toggle on the pressure switch can be set to either N.O. to close or N.C. to open contact transfer upon operation.
