Optex RC-20U 3 Channel Receiver Chimebox w/ Relay

We needed to add a second chimebox to our system. Ordered this one and the ease of setup was amazing.

Oh, it works great but after a while of the sheep passing by it one at a time it gets kind of old.

This is a replacement receiver for and Optex driveway alarm that was 20 years old. The quality is remarkable, the 9 volt battery last forever, and we really appreciate knowing when someone comes through our gate. There are false alarms like when a gecko decides to check out the funny looking device.

Got it for work, and it works great.

Perfect

Works. Just had to follow the instructions, since this required programming the receiver with each specific sensor unit to enable its operation. As in past use, I also painted my own drab camo coloring on the sensor unit to make it “hide” in the front yard foliage by my driveway where I park the unit (photo). It’d be nice if they just came in that color already. That last one I had lasted almost a decade despite permanent exposure to sun and rain outdoors (along with getting kicked around occasionally by night animals).

put it by your driveway, back doors, near your car in the driveway and it will wake you up in the night to let you know something is moving around nearby. The batteries in the outdoor sensor last well over a year, though out all temps.

Purchased to notify when someone opened the front door. The alarm actually is in an adjacent building not too far away. We were concerned it would reach the distance going through 3 walls. Luckily it works fine. Simple to install and use.

working good for my bussiness

Difficult company to work with and impossible to return unwanted item.
