Don’t Get Hosed And Get The Wrong Hose (or Inlet)

I like central vacuum cleaners. Having the power head in the garage and a series of inlets throughout the house all connected by tubing hidden in the walls is the equivalent of having structured wiring for your telephone, data, and CATV needs.  What I want to bring to your attention, whether you are planning a new install, adding a new inlet, or just replacing the hose, is that you need to make sure that the hose matches the inlet.

All inlets have two, spring-loaded metallic nubs that make contact with a ring on all hoses when the hose is inserted in to the inlet.  This low-voltage contact triggers the power head motor to turn on when the hose is inserted and off when the hose is removed.  The Nutone NU360 is a standard, low-voltage inlet. 

In additon to the low-voltage contacts, there is another type of inlet that has a trapezoidal shaped connector above the circular inlet that allows 120 VAC, household electrical current to safely flow through the hose and drive power brushes and other AC-powered cleaning accessories attached to the hose. The NUCI390 is an example of an electrified, direct-connect inlet.

So which hose do you use? If you have the standard, low-voltage inlet, then the NUCH230 is the hose for you. If however, you needed more cleaning oomph in the form of an electric power brush, you would need to get a different hose such as the NUCH520. The ‘520, pictured above,  can be inserted in a standard inlet, and comes with a six-foot, pigtail AC power cord attached to the inlet side of the hose.  The pigtail allows connection to a nearby electrical outlet thus allowing the use of the power brush.

The third and final hose is the NUCH620.  This is an electrified, direct-connect hose. No pigtail. Just plug it in and you’ve got both suction and AC power at your control.

Switch Between CATV and Modulated Signals

Do you have security cameras that you wish to view on your TV? Do you want to avoid any issues that may come up when you combine modulated signals with your CATV signals?  Don’t want to mess with low-pass filters and notch filters? And you want to keep the cost down?  If you answered “yes” to all of these questions, then I have a product that you need to take a look at.  It’s the RF Switch, ALRF2X, and it allows you to switch between two sources using 12 VDC.

RF SwitchYou can install the ALRF just upstream of your RF distribution module.  CATV will be the default input, connected to NC, and the modulated signals connected to NO, with COMMON going to the input of the RF distribution module.  The included 12 VDC power supply can be connected to an X10 appliance module or a UPB appliance module, and be controlled by the applicable transmitter.  For CATV, the appliance module will be OFF, and to view the modulated signals, turn the appliance module ON.
