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!

I own the simple safe system that works great! However, the alarm that came with my package, the cone, wouldn't scare a small child. I read all the reviews and was convinced this was necessary. I is really loud with the 2 sirens hopefully I will never know that it scared the potential perpetrator off. This system is a snap to install and the staff are wonderful to deal with if you have trouble. Better to be safe than sorry!
