How is the transmitter powered? Does it have a battery or does it depend on the AC for operation. Will it work on a dead circuit?

The transmitter is powered from the AC line, so it does not work on a dead circuit. The receiver is battery powered.

The transmitter is powered by live ac circuit. No it will not work on a dead circuit

The transmitter is powered by a live circuit, a hot and a neutral, it will not work on a dead circuit. When you locate the circuit with the sounder wand, turn it off then walk back to the transmitter, the red led on the transmitter should be off. If the light is not off, you haven't turned off the right breaker. Hope this helps.

Hi, the Control Center (receiver) comes with an ac adapter but uses 4 x 1.5V AAA batteries for loss of power back-up. The transmitters (sensors) use 3.2 V lithium coin cells (1 for each) CR2032. Transmitters batteries are expected to last up to 2 years. If the sensor battery is weak or signal is lost, the Control Centre light will start flashing as a warning. Hope this helps.

It's battery or ac powered. Mine only was used about 6 times before it broke.

My unit doesn't have a battery. It plugs into the house current and receives it's signal from the transformer attached to the house main door bell. (It works just fine.)

It is not powered, it is a passive antenna. Just plug it in and position it where you get the best reception for your application. Good luck

It Pulls power from the AC unit, batteries are primarily for backup. Otherwise, no it can not be powered with a power supply.

It must be plugged into electricity but it wireless. However, the range is a little limited. Mine is about 60 feet from the main unit but doesn't pickup the signals. Maybe not have the clearest transmission route.

There is a transmitter and a receiver. Both take the 9 volt battery. Batteries last pretty well and I seem to get more than 20 hours of operation them.

Only the receiver plugs in to 110V. The transmitter has a 9V battery that last longer than a year and is easy to replace - the unit flips down. I have been using one over a side iron gate for years. I was so pleased with this product I recently purchased another receiver and 2 transmitters. I plan to mount one over my driveway.

It's not battery operated. This is a CCTV camera that plus into a CCTV system that runs on converted AC to DC power.

it is AC powered. however, I have had problems with my wireless speakers due to interference. they tend to cut out a lot. can't figure out where it is coming from.

It has to be plugged in to work, but it works very well on dead batteries as well as keeping batteries charged in vehicles that don't get driven often.

I have not tried this, and it is true the transmitter needs to be powered, but in a car you can use an inexpensive power converter to get the 120v, or insert batteries in the transmitter.

It is battery powered -- 12V car battery. It could be modified to run off any 12V constant DC power source.You couldeven cut a on/off switch into the circuit (a weak point for the unit) You must unplug the unit to take it off power source.

Yes, the transmitter needs power to transmit. It comes with a long cord with a very thin wire connecting the last 4 or 5 feet to the transmitter.

Its plugged into an outlet. It comes with the ac power connector. The battery is for remote alone.

They both have batteries. My transmitter battery went dead a couple times, but I never had a low battery message, just blank displays. I operate the receiver on a/c so never had dead batteries there. LT
