Customer Ratings & Reviews

Like others have said, pretty loud. I have 3 of them, 2 in front and 1 in rear, I want the neighbors to hear them. The only thing i have reservation on is the battery life in winter, cold eats batteries in all my trail cameras,,, time will tell.

Michnlouder than the previous generation. Easy to install accessory

Was really easy to set up. We tested our system with the town code inspector present. On Home mode, the inside base system went off immediately and then the aux siren sounded off after a second or two delay. nice and loud!

Very loud! Easy to add to your system. Would definitely wake me if someone trips my alarm system!

Was looking for something LOUD - this is it. Super easy install. Highly recommended!

Loud & clear siren that can be heard at a distance.

Very loud, easy to install and easy to setup onto your existing Simplisafe system.

This is a must if you want entire house to get the siren simple to install and to connect to the system

I have three of these. One in the basement, one on the first floor and one on the second floor. I will say this - be very careful when testing this. It is VERY loud and could possibly damage your hearing. My alarm was accidentally set off early one morning when one of my entry sensors fell off a window and even sleeping with earplugs in, it woke me from a dead sleep. As an added bonus, it can be set to chirp when any of the entry sensors are opened. It also chirps on the countdown when the alarm is armed. I still want one more for the garage, and then I'm done!

I would recommend this aux siren to anyone with a SimpliSafe system, especially if you have a large home. The base station is loud but does not cover our entire home. We got this siren and configured it to also chirp when the alarm is counting down to arm or during the delay when entering before disarming. The keypads are very quiet and this is an excellent reminder to disarm, especially for the kids.

Wanted to purchase and extra sirens for my SimpliSafe alarm system because the one on the unit wasn’t that loud. I set the extra siren and WOW, super LOUD!! Big difference compare to the base unit siren. Must buy if you own a SimpliSafe alarm system.

This is a Siren! I was a bit frightened to test it. I called customer support for encouragement. They walked me through this and was very I was very Impressed. This is a perfect security system which provides a bit of peace of mind. Who wants to come home and look in all the closets, under beds and behind the shower curtain? Peace of mind

It's loud enough to scare my dog, and hopefully intruders. Easy setup.

This thing is insanely loud. I got it to put upstairs where our bedrooms are. We sleep with fans on and can barely hear the base station downstairs when it goes off. This thing is almost too loud for inside.

fast delivery easy to install great siren

Installation was simple, super loud compared to the base alarm

Easy to add to system loud to hear thoughtful house

This additional siren works great! Mounted outside and now all the neighbors will be alerted when the alarm is triggered. It was very easy to pair with existing system as well.

Decent add-on module. No other choices, really. the mounting bracket isn't as secure as I'd like and the included adhesive was not effective enough to work.

great add on for the SimpliSafe alarm system especially if you have a larger space and want to make sure that the alarm can be heard throughout. Just like the rest of the products, easy install and add to the system.
