Essential Info

Use the Wireless 2000 Annunciator as a perimeter alert for your home or business, a driveway alarm to detect approaching vehicles, a wireless doorbell, a warehouse delivery notification system, and many other applications. The Wireless 2000 alerts you that a zone is breached with one of three tones. The alert tones have five different sensitivity levels and can be set to sound up to 80 dB. If you choose to incorporate more transmitters, the receiver can also identify which zones have been breached by certain tones. Up to 12 transmitters can be incorporated.

The Wireless 2000 comes equipped with two detection patterns that adjust easily for perfect aiming: a long range of 50 feet and a fan pattern range of 17 feet. One of the more useful features of the Wireless 2000 is that you can trigger other devices, such as door strikes, lights, sirens, cameras, and more. The trigger system utilizes a weatherproof motion detection sensor that is about the size of a softball and can be mounted easily on any wall, ceiling, fence post or desktop both in-and-outside your home or business. The sensor operates off a 9V battery meant to last an average of two years, while the receiver operates with an AC adapter included in the kit.

    DENNIS -- lenox, MI   10/28/2013
    I bought this for a second alarm down my driveway but had a hard time teaching it a second alert sound. Great product but a little complicated to set-up.
    BARRETT ENTERPR -- scottsdale, AZ   8/23/2013
    easy to setup and easy to install.
    Stuart -- lake success, New York   7/20/2013
    This product is OUTSTANDING! I haven't replaced the battery in years! The motion sensor is so sensitive that it picks up rain drops when I water the lawn nearby. It is an OUTSTANDING product.
    TAMERA -- portsmouth, RI   5/6/2013
    Best we can find durable and consistent.
    HANK -- columbiana, AL   2/2/2013
    It was exactly what I ordered and arrived on time. Thank you.
    PAT -- hyde park, NY   6/8/2012 better than i thought it would.
    KEITH -- clarkesville, GA   5/25/2012
    This item works great it is about 100 ft down driveway and receiver is in the center of the house an still picks up signal with no problem. It picks up cars and trucks great and squirrels. I have also found out that i have 2 stray cats that walk up my driveway most nights about eleven and set it off. Great product. (I did build a box to protect the transmitter from the elements because I felt the unit might not stand up to well to weather by itself.)
    BRAD -- montgomery, NY   2/14/2012
    horrible product. many false alarms. avoid at all costs. Made in Malaysia just like china junk.
    O'NEIL -- elk point, AB   1/5/2012
    I like it a lot this is my second unit The fist lasted 18 years If it wasnt for the cat peeing on the reciever it would still be working
    JANICE -- brownsboro, TX   11/25/2011
    After about 2 months it's working great. I have it outside and have worried a bit about the rain, etc, but no problems. Great little alarm!
    ALBERT -- reston, VA   11/25/2011
    Works as advertised. Motion detector is amazingly sensitive.
    TIMOTHY L -- orono, ME   11/20/2011
    Arrived promptly. Easy to install and works okay. Have not had it long enough to have an opinion on its longevity/dependability.
    JAMES -- kodiak, AK   10/30/2011
    Works very well. I especially like the volume control. More reliable than the previous 2 alarms I had installed.
    MARTI -- deerfield, NH   10/23/2011
    The range is great and the motion sensor is pretty reliable, although we did have to make sure there were no tree branches nearby that might move in the wind. What we don't like about it is that the motion detector's range seems pretty limited--it was very difficult to position it so that it would cover all of our driveway. We're disappointed that we were unable to find a way to set it up it so that it could also reliably cover the rest of our lawn along the street (about 4 times wider than the driveway. However overall we're still pretty happy with it.
    JYNELLE -- beaumont, TX   9/30/2011
    This item replaces an identical driveway sensor that we've had for many years. It is extremely easy to set-up and the outdoor sensor holds up to years of weather.
    ANN -- walla walla, WA   9/17/2011
    We have not installed the unit as of this time. Not able to provide a rating yet.
    IVEY -- lubbock, TX   9/8/2011
    This has been a great product for us already. We own a large greenhouse, and we are often working a long way from our retail area. This product keeps an eye on the door for us.
    SALLIE -- cincinnati, OH   8/5/2011
    Works great
    TOMMIE C. -- hillsboro, OH   8/5/2011
    This is my second purchase of this item. My last one lasted about 17 years and then the transmitter began to fail. After I set up the new one I set the original receiver to new one and now I have two receiver that work fine. I recommend this to anyone needing a drive up alarm. One word of caution - Don't point it toward the evening sun. TCG

    No issues with return of item and refund
