I added this right over the door and it definitely gives you a scare when it goes off. I think it’s needed because just the base alone doesn’t give ppl that scare. I believe by having this, makes someone who’s breaking in think twice

Connecting this to my alarm was very easy with no issues. Mounted it outside and tested the siren by setting off the alarm. It is VERY LOUD and can easily be heard by your neighbors. There was about a 2 second delay from when the base went off till this siren started and as soon as I disarmed the base this stopped. Works great and highly recommend!

Love this alarm system for my small home. Great price. Needed an added alarm for upstairs. Don’t buy any other
