 Optex RCTD20U Wireless 2000 Entry Alert Kit The Optex RCTD20U Wireless 2000 Entry Alert Kit is great for those that would like to know who's outside their house before they even reach the house. This transmitter and receiver set will do that for you!! The Optex RCTD20U Wireless 2000 Entry Alert Kit has a RC-20 receiver unit and one TD-20U transmitter. The Rc-20 can pick up signals from up to three TD-20Us.

This means that if you have a horseshoe style driveway; you can cover both entrances to your home. The transmitters can be set to shoot a single beam or you can have it shoot out a fan pattern. You can create a barrier or catch anything in a radius of the fan pattern. It also has selectable chime tones. This unit, the RC-20, can also trigger lights, sirens, etc. via a relay. This means that you can wire this into a zone on your alarm system. All-in-all this is a very handy piece of equipment to have to keep you informed about traffic coming onto your property.
