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

Michnlouder than the previous generation. Easy to install accessory

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

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

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

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!

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.

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!

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.

Installation was simple, super loud compared to the base alarm

fast delivery easy to install great siren

Easy to add to system loud to hear thoughtful house

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.

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

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.

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.

Easy to Install and works as described. This can be set so loud that anybody, including people who live with you, who remain in the house when this goes off are either deaf, disabled or are a '60 watt bulb in a 120 watt world.'

SimpliSafe products are well-made. This is the same thing you can get from their website for the same price. No complaints whatsoever.
