The Model PCVS is a weather proof and tamper resistant switch for monitoring the open position of fi re sprinkler control valves of the post indicator, butterfl y 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 butterfl y valve housing. The device is engaged by the indicating assembly of the post indicator or the operating mechanism of the butterfl y 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.
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.
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).
