Essential Info

The 433MHz Wireless Universal Transmitter can send an instant RF signal to your DSC 8 - 32 Zone Security System in the event that an unwelcome intruder attempts to enter your home. The security system receives wireless signals through the 433MHz Spread Spectrum Wireless Receiver or LCD Keypad with built-in 433MHz Wireless Receiver, which is required for any wireless transmission and is sold separately. Runs on an included 3V Battery (CR123A).

What's Included

  • Wireless Universal Transmitter - WLS925L433
  • 3V CR123A Battery

Door/window contacts, PIR motion sensors, and additional accessories are also sold separately.

    Ideal for door and windows, the 433MHz Wireless Universal Transmitter can be used directly on the frame with included magnet mounted on the door or sash. Terminals are also included for an external switch.

    works as advertised

    Excellent service. The product has been delivered and received on time. All questions have been answered quickly and accurately.
    BRAD -- moulton, AL   2/24/2013
    Installation was real simple, as was the programming. One transmitter would not work, but we had to use the magnet. Therefore, I could not return for a partial refund. Will not order anything else.
    RUSSELL -- lincoln, MA   3/5/2012
    Big improvement over predecessor although we did have to modify the cover to permit access of 2 external switch wires.
    THOMAS -- west hartford, CT   9/14/2004
    Nice size. Only has 6 digit (hex) serial number (literature included states it has both 5 & 6 digit - a problem for older systems).
    MICHAEL D -- granada hills, CA   8/23/2003
    I misinterpreted the information in the item description so I am not as pleased with my purchase, but it will work out fine.
