Optex TD-20U overview

  • 1Description

The TD-20U Indoor/Outdoor Sensor Transmitter from Optex offers two selectable detection patterns, a 17' fan pattern or a 50' beam pattern. The sensor uses PIR to detect motion, and once motion is detected it sends a signal back to the RC-20U Chime Box Receiver using RF signals. The device is powered by a standard 9V battery (available separately) which can last for approximately 2 years when the sensor is triggered about 250 times a day. There is a red LED that indicates when the sensor has detected motion and when the battery is low. Up to nine TD-20U units can be added to one RC-20U Receiver, enabling you to set up a full perimeter around your property.

When used with the 50' long-range detection pattern, the transmitter is suitable for applications such as driveways, entryways/walkways, warehouse delivery areas, constructions sites, art galleries, drive-up windows, delivery doors, and similar scenarios. When used with the 17' fan (wide) angle detection pattern, the transmitter can be used to monitor hard to see items, merchandise that is prone to shoplifting, inside display cases at jewelry stores, department store dressing rooms or fitting rooms, the unauthorized use of emergency exits, supply rooms or closets, and home or business entry points. With an IP54-rated housing, the sensor is suitable for use in outdoor areas for a wide range of applications.

    Optex TD-20U reviews

    TD-20U Indoor/Outdoor Sensor Transmitter for Wireless 2000 System is rated 4.3 out of 5 by 8.
    Rated 5 out of 5 by from Works like a champ I had this unit before. It randomly stopped working. I contacted the manufacture. They said I could replace the transmitter and re program the 2 receivers it would work fine. I got the new transmitter and it took 2 seconds to re program my current receivers. Works great. We have an up stairs at my business and having the transmitter broken makes it hard to know when customers come in if you are up stairs with a customer. Love how fast it came, and how easy to install and re program!!! Thanks

    Rated 4 out of 5 by from Great for announcing incoming vehicles and pedestrians I recently purchase two to replace the two I've had in constant PNWest weather for the last eleven years. One of them had finally succumbed to the wet. I created a third zone with the other. They detection works well, announces incoming traffic in the driveway just fine. It does have its occasional miss or false detect due to sunlight and dancing shadows from the trees. If you have a dog the annunciater chime will have it trained in no time to run out for a meet and greet.

    Rated 5 out of 5 by from Good product This transmitter is a replacement. The original lasted three years until rain got into it. It is located around 200 feet from our house. There is a forest with thick bushes between the transmitter and receiver. It is not visible from the house even in winter. It works perfectly as did the original. Shipping and delivery happened as promised by B&H. The whole Optex system has worked great.

    Rated 1 out of 5 by from Does not fiction as stated by the manufacturer This is the third TD-20U that I have purchased. I use the first two Outdoors with about an 80% accuracy rate. I added this third unit to my system and am completely disappointed. It faults all the time. I have relocated it three times and it still faults. I gave this unit one star, since I can not rate it with zero stars. I am truly unhappy with this ubits lack of performance.

    Rated 5 out of 5 by from A must have!!! These things are the best for anywhere you want to be notified when you have some scum of the earth, like Dirtbag Tweekers, pulled into your driveway, sneeking into your yard, or even in your garage. The 3 different audible tones, offered on the in home monitor, allow you to identify what area of your property that dirtbag is in.

    Rated 5 out of 5 by from Every business should have one of these! The product does what it is intended to do. It works perfectly, notifying us of customers entering or exiting the business. It's use is outside so it holds up to the elements. It's reasonably priced. You won't miss any customers entering your lot or your store if you put one of these to use.

    Rated 5 out of 5 by from Works great Ordered this product as a replacement for old failed ones. B&H had a better price than the factory and I received them in three days. They are installed and working as required. Thanks for the prompt and courteous service from B&H.

    Rated 4 out of 5 by from Good Product for the money We have been using this product for 14 years to alert us for perimeter breaches of our home. Different sounds for different entrances. This is a great low cost solution. This one transmitter was a replacement.
