The model PCVS is a weather proof and tamper resistant switch for monitoring the open position of fire sprinkler control valves of the wall and yard post indicator and butterfly types. 2-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 in 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 switches 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.
