The UT-3000 is a simple to use universal transmitter that is compatible with the other 3000 Series products. The UT-3000 operates on a 9 volt battery and has several different methods of activation. First, the UT-3000 has a push button that can be used as a panic button or a wireless doorbell transmitter. The UT-3000 also has terminals for either a normally open (N/O) or normally closed (N/C) input. These inputs can be used with any detector contacts. Now you can have your favorite detector send a wireless signal up to 600 feet back to either the PR-3000 or WR-3000 receiver. The UT-3000 is ideal for locations that are difficult to wire.
