Great product.
Review by Bill

Overall the Guardian is a great product. I currently have four of them. The only issue I've noticed is that the the volume on the alarm varies. One I have is about half the decibel level of the loudest.

Have question about the longevity of the batteries. How long are these batteries supposed to last if the sensor they are in is on a window that never opens?

Can I program a second remote in addition to the first ?


Hello JC, Yes you can have multiple remotes paired to the system. Thanks, Jessica Customer Service Manager


The red light on my remote control doesn’t go off, I just replaced both batteries in the remote & it’s still a solid red. How can I get it to go off?


Hi, Mike, Generally that red light is an indicator of low battery; I would recommend testing those batteries to make sure they are good, and verifying that they are inserted correctly. If everything checks out, and that light still does not turn off, we can replace that remote under warranty for you! Regards, Amanda, Fortress Security Store


What external siren can I use with this to make it louder?


Hello, Unfortunately our external sirens are not compatible with our Stand alone Guardian systems. Thank you, Fortress Security Store!
