Query: Great alarm system

The SC-1000 is a nice alarm for the money. I have been using it for 3 weeks. Easy to set and so far no false alarms. I read the directions twice before installation. Pretty straight forward if you read them. I ordered both the SC-1000 and the SC-10 because I wanted two more remotes (which work great by the way) and two more sensors. That was the cheapest way. The SC-10 remotes and sensors had to be programmed to the SC-1000 panel. If you read the directions, it's easy enough. I put the dialer upstairs in a bedroom near an AC outlet and phone jack and set it to silent. The SC-1000 control panel, which has the siren in it, is in a corner and can't be seen. It's very loud. If you have a remote, the panel can go just about anywhere. I have turned it on and off from outside the house. I emailed support with a minor question and they responded within a few hours. I highly recommend this product. A good value in my opinion.
