The Model PCVS is a weather proof and tamper resistant switch for
monitoring the open position of fire sprinkler control valves of the post
indicator, butterfly and other types. Depending on the model, one or
two SPDT (Form C) contacts are provided which will operate when the
valve position is altered from an open state.
The unit mounts in a 1/2" NPT tapped hole in the post indicator or
butterfly valve housing. The device is engaged by the indicating
assembly of the post indicator or the operating mechanism of the
butterfly valve, actuating switch(es) when the valve is fully open. The
unit should be installed where it is accessible for service.
The cover is held in place by two tamper resistant screws that require
a special tool to remove. The tool is furnished with each device and
should be left with the building owner or responsible party. Replacement
or additional cover screws and hex keys are available. See ordering
information.
Optional Cover Tamper Switch
A field installable cover tamper switch is available as an option which may
be used to indicate removal of the cover. See ordering information.
Testing
The PCVS and its associated protective monitoring system should be
tested in accordance with applicable NFPA codes and standards and/or
the authority having jurisdiction (manufacturer recommends quarterly
or more frequently).
