Essential Info

Increase security to exterior entryways of your home or office by installing the Enforcer Indoor/Outdoor Wall Mounted Photoelectric Beam Sensor. This Transmitter/Receiver sensor has a all-weather, waterproof enclosure and a range of up to 35 feet that ensures reliable operation in just about any environment. The kit includes brackets designed for wall mount applications for both the sensor unit and the beam reflector. Some typical applications for this product would be as a safety sensor for garage doors or outdoor gates, overhead door security sensors, entry detection for store fronts and more. When the beam is broken, the sensors will turn on the LED light and trigger a normally closed or normally open relay output on your alarm system or warning device.

This product requires a 12VDC-240VDC or a 24VAC-240VAC power supply, sold separately.

    Outdoor Rated
    The Enforcer Indoor/Outdoor Wall Mounted Photoelectric Beam Sensor has been given a weatherproof ration of IP66, which is ideal for outdoor use. Ingress Protection (IP) is rating for electronic products as it relates to the amount of sealing they have against the entry of solid and liquid objects. The first number '6' refers to the degree of protection against access to hazardous parts and ingress of solid objects, 6 is the highest rating at "dust tight; complete protection against contact". The second number '6' refers to the degree of protection of the equipment inside the enclosure against the harmful entry of various forms of moisture, 6 is one of the highest ratings at "protection against heavy seas, or powerful jets of water".

    Good purchase, fast delivery.
    VIC -- saint augustine, FL   7/3/2013
    so far it has worked as advertised. its been raining a lot and its works fine except sometimes the mirrow will get rain drops on it and it interferes with the beam. I think a rain guard over it will eliminate the problem, other than that I am pleased with its performance.
    MICHAEL -- corona, CA   5/30/2013
    Very good quality product. Highly recommend.
    ROB -- lakeway, TX   4/17/2013
    Easy installation, works as advertised. I wish the chime could be programmed with custom sounds rather than just the generic sound. Plenty of volume.
    JEFF -- dundee, OR   2/3/2013
    I am not happy with the sensor at all....It has failed 4 times in a 8 day period......
    JIM -- ponce, PR   1/20/2013
    Worked perfectly. I did the instalation myself and saved over 300.00 over what I was quoted.
    JIM -- los altos, CA   10/7/2012
    Small and unobtrusive. Easy to align - took less than a minute.
    BEN -- coulterville, CA   1/28/2012

    BRAD -- corning, CA   10/21/2011
    All my questions about the product were answered correctly. The product was delivered very quickly. Hook-up was very easy. The versatility of power input supply is amazing..from 24v AC to 220v DC all with the same wiring!
    KAREN -- oshkosh, WI   9/19/2011

    KIRK -- morgan hill, CA   8/29/2011
    worked out great after I figured out how to wire a power supply to it the enforcer 12v dc. power supply does not plug right but yet Smartphone says You have to have it and they don't make returning it easy as the say they do online and You can not call for returns at all !!
    KELLEE -- newcastle, WA   7/18/2011
    The Enforcer photo beams work great. I am using them around our house to turn on lights using a relays and they work perfect! They are small, waterproof and easy to install. Another plus is that there is no place for sugar ants to crawl inside and nest (a problem several of the competitors IR sensors have).
    BRETT -- flint, MI   5/13/2011
    Easy to install, works better than the system I had been using. Only complaint is I wish the volume would go higher, I am using it in an auto repair shop and if our air compressor is running it is hard to hear. Fast shipping, thanks for the great product Smarthome!
    Bill -- springfield, Or   5/12/2011
    excellent! I am ordering two more today just to have on hand for projects yet to be invented. This is the best designed product I have ever seen for the home or industrial user. Freedom of power supply, full isolation of output. accurate operation, easy setup, variable sensitivity. I can't think of anything I would add. excellent!
    R W -- pasadena, CA   3/7/2011
    It did exactly as it was described. No suprises
    AL V -- lakewood, CO   12/10/2010
    Good product description and prompt siervice in fulfilling our order.
    JEAN -- spray, OR   10/29/2010
    not enough instructions on how to connect it to electricity.still trying to figure it out.
    DOUGLAS -- sandia park, NM   10/8/2010
    Works well but a bit tricky to align. Would be great if the mounting bracket had some set screws to make some small alignment changes
    TIMOTHY -- rustburg, VA   9/9/2010
    worked well, used for business entrance
