Pressure Switch Termination
Closing of any shutoff valves between the alarm check valve and
the PS10-EXF will render the PS10-EXF inoperative. To comply
with NFPA-72 any such valve shall be electrically supervised with
a supervisory switch such as Potter Model BVS.
An uninsulated section of a single conductor should not be looped
around the terminal and serve as two separate connections. The wire
must be severed, thereby providing supervision of the connection in
the event that the wire becomes dislodged from under the terminal.
