Not sure if he is or isn't, but i did know of a PLC or UPB (forget) one at EHX last year. The idea was you could have it shut off when the doorbell rang or something silly like that.

Didn't think about that... that would be a good idea.

In that case just use a C4 switch to shutdown the central vac when the doorbell rings.

too bad the outlet switches arn't shipping yet, apparently they sence if a load is on or off. plug and play baby!

The idea is to have the vac shut off if the phone rings or the doorbell rings. The C4 plug-in outlet would do the trick.

Most vacs are plugged in so, you could yank the duplex box out, add in a remodel 4-plex box, add a c4 switch to control the duplex outlet. This way you have a solution to control the power.

You can't sense voltage with those though. I guess just turning it off is fine though.

Most CV units are turned on with a relay at the can. Can you not use a normally closed relay and then open it when the phone or doorbell rings?

You certainly could, but the real application is how long do you set this for? The customer is using the VAC and you kill it for 30 sec. then while he is talking on the phone the relay kicks back in and the unit start again blasting his tel conversation. Maybe you could simply pulse it a few times to get them to pull the hose out before answering the call.

Some ideas are novel, but the implementation requires more thought. Cool concept and with a relay connection, very cheap to implement.

Got to love this stuff!

You can use a phone line voltage detector. Similiar to the way Tivo, or other devices sense when the phone is in use. This is how a multi line phone that is not part of a PBX lights up when a telephone somewhere else connected to the same line is using it.

Good one Dan, As long as the phone is off hook, no VAC.....

But what if the cleaning lady is downstairs and your on a call in the Bedroom?

hehe

I think its a rack mounted C4 controller that sucks your $money$ into switches, tvs, pjs etc etc all done via a wireless zigbee mesh network :)
