Essential Info

The SECO-LARM Two-Channel RF Receiver can be used to control garage doors, house lights, alarm control panels, or other devices via a remote control. It has 5 programmable output modes which are 4-second momentary, toggle, latch, validity, and 1 second momentary. It comes with two independently programmable channels and is compatible with all SECO-LARM transmitters. The Two-Channel RF Receiver also features SECO-LARM's patented CODEBUMP technology, plus a Coding IC for rejecting unwanted RF signals.

SECO-LARM's patented CODEBUMP technology will protect you from the modern day thief. With CODEBUMP, so-called code-grabbers and scanners are rendered obsolete because the RF code changes every time the transmitter button is pressed. In addition, with over 18 quintillion (1.8x1019) codes, the chances of ever repeating a code are virtually non-existent. SECO-LARM's CODEBUMP transmitters and receivers are perfect for controlling garage and gate openers, car and home alarms, plus much more.

    I have a solar operated pump (~24 volts as fed directly from the solar panels). I use the SECO-LARM SK-919TD1S-UP 1-Button Wireless Transmitter together with this receiver, to turn the water on/off when I am watering the garden, or when using the water for processing produce at my wood fired stove. I don't get more than about 150 ft from the receiver and this system works great for me. Programming and installing the receiver was very easy.I bought two of the transmitters and could use one to control a different device if needed. I programmed them both to control the same pump though. That way if I forget to bring one transmitter, the second one is kept in the shed where the pump is and I don't have to make a trip back to the house (garden is remote from home and utility power).

    Nicely packaged unit and quality components as well as easy to connect. The one drawback, is the one second delay of relay deactivation after the button is released, so if you need an instant deactivation of power while in the momentary mode, this is not the receiver for you. I tried to use it for my wheelchair lift but was unable to because the lift would keep moving for one second after button was released...something that is just not acceptable as the lift would move 3 or 4 inches in that time. So, for that reason I gave it only 4 stars.

    Awesome product! Easy to program and install. good connections on the PCB, simple instructions. Good range on the transmitter.
    PATRICK -- hilo, HI   11/25/2011
    Installed and working fine.
    MARTIN -- berlin center, OH   10/15/2011
    The only issue I have with this item is when set on toggle it often only works in one second increments. It won't stay on until released. This is frustrating as I'm using it on an air suspension on a custom motor cycle.
    MATTHEW -- san fernando, XX   9/2/2011
    This item is working good so far.
