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

Was happy that it is louder than expected. Alerts neighbors as well as us.

Only had it for a short bit but works well. I didnt realize it beeps when then count down timer starts which is a very nice surprise.

Very easy to set up in app and in a location you select. Alarm can be removed from holder to change batteries. And siren VERY LOUD. Great item!

It was easy to install and motion detection was great and loud.

Had for about a year now. Made it through one summer and one winter, batteries died 2 times which told me something was wrong the unit at that time. Now wont stay connected and keeps stating Battery needs replacing. Too bad. Because when I bought this, it states outdoor use! Now the list says under shelter outdoors , whatever that means. So waste of $60. Imo

This sucker is loud! Would wake me from death, I think. Paired easily with my Simplisafe system

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

My sister accidentally set off my alarm the other day. The base unit alarm definitely isn’t loud enough to scare someone away. It took me a minute to figure out what the beeping was. It didn’t even occur to me that it was an alarm. That occurrence prompted me to buy this auxiliary alarm. I tested it, and it is extremely loud. This will send the bad guys straight back out the door.

It was easy to install . Works great ! However , I was expecting it to be a little louder honestly . It’s really not that loud

this add on device is working good at 150ft so far as remote siren inside an outbuilding. I have not had a chance yet to determine my permanent mounting spot. So Im slowly moving the siren device to determine & map full remote range. I will update when finished with map range measures. so far very good results.
