The LRA-DCTX is an indoor rated door/window contact sensor that will transmit a signal, up to 1000 ft. away to the compatible receiver, the LRA-DCRX.  Simply mount this transmitter on your door and when it opens, it instantly sends a signal to the receiver where a chime sound/melody is played.

Like all products in the LRA series, this sensor/transmitter is compatible with all the Safeguard Supply LRA series of products.  Each receiver in the LRA series, the LRA-DCRX desktop receiver and the LRA-VPRX portable receiver, is capable of working with four different sensors/transmitters and will play a corresponding sound for that zone.

The door/window contact mounts to the door and door frame using the supplied double-sided tape.  Install the supplied long lasting lithium batter, mount it to the door, then pair it with the portable or desktop receiver and you will instantly start receiving alerts.

You may use this product as an add-on to your existing products or buy the sensor together with a receiver by purchasing the LRA-C1000 Door Entry Alert Kit.

Love this company--love all the products I've purchased

I recently purchased a doorbell extender for a client of mine. I'd nearly forgotten about the extender when I happened to be doing tax paper clean up and ran across an invoice from a job i did quite awhile ago. With COVID, many of my clients have moved indoors and aren't always able to hear their existing doorbells. These items are perfect, easy to install and work fantastically. The prices are fair and shipping is oh-so-speedy! I'l be ordering plenty more and you should, too!

LRA-DSTX Driveway Sensor

Ordered another Driveway alarm sensor received it on estimated time and well packaged. I ordered this new sensor because my Driveway is almost 200 feet to the bottom the first one I installed at the bottom so as to know when someone pulled in and installed this one at the top of my driveway that way I know when someone is here in stead of someone just turning around at the bottom then I can look at my security system and see who it is works great me on a dead end road and with different tones I know exactly what is going on

Well done - it works GREAT

It is the best of several I have tried in the past including the famous x-10. Simple to set up and works well over 200feet away from receiver. I have put the motion detector in my mailbox out at the edge of the street; now I know when mail has been delivered to my mailbox which I can not see from my home.
