VM195: Wall Inlet Valve (White) The Model VM195 Wall Inlet Valve (White) provides a connection point for a central vacuum hose, controls the central vacuum power, and seals the vacuum system when not in use. A spring-loaded access cover flips open for insertion of the vacuum hose. When the cover is closed, a gasket seals the wall inlet valve. This wall inlet valve is also available in almond (VM195A) and black (VM195B). Two terminals on the rear of the wall inlet valve connect to the central vacuum’s low-voltage control wire. When a central vacuum hose is inserted into the wall inlet valve, two sensing pins in the valve connect to the trigger ring on the hose end. Some hoses have a solid trigger ring that electrically connects the valve’s sensing pins whenever the hose is inserted into the valve, which starts the vacuum. Other hoses have a split trigger ring that’s connected to a low-voltage control switch in the hose’s handle, allowing the operator to control the vacuum unit’s power. The VM195 Wall Inlet Valve attaches to Models VM149 and VM241 Wall Inlet Valve Brackets. Features Available in white, almond, and black Spring-loaded access cover for vacuum hose connection Seals the vacuum system when not in use Sensing pins control the vacuum unit’s power via the hose’s trigger ring
