SimpliSafe 105dB Auxiliary Siren - Compatible with Gen 3 Home Security System

Nothing I disliked.

great system easy to install

Ordered this to supliment my systems built in siren, which itself is not very loud, but still very low sound emitted from this additional siren. Would not really scare anyone off and your neighbors would probably never hear it. Simply safe products all seem to be high quality and durable and super easy to install, they just need a louder siren option.

Battery life is about a week. I changed the spot and now I have zero issues

Didn’t work with Samsung SmartThings

Loved the simplicity and easy to follow instructions.

I just bought and received this siren for SimpliSafe. Installing it was a breeze like a SimpliSafe products. However, the siren did not work properly. So I called SimpliSafe and spent the next half hour trying to solve the problem. They could not solve the problem so instead of returning it back to Amazon, they said they will send me a replacement product that I will have to exchange and send back the defective one. So buyers beware of this issue as this is the second time it has happen. Instead of buying it on Amazon, buy it from SimpliSafe instead. You may not be getting a brand new or refurbished one instead. Lessons be learned……

Easy to install. If any door sensor is triggered the alarm starts a audible countdown. If the alarm is not deactivated the alarm sounds and police are notified. I have two alarms -one on the 1st fl and one on the 2nd fl. Nice product-gives you some peace of mind with all of crime going on.

This alarm is loud compared to the base unit. I wanted to be able to hear the alarm on second floor so this will definitely do the job.

So easy to install and SIGNIFICANTLY louder than the home base alarm.
