Easy to install, has sticky tape on it so peel off the cover and stick it to a wall or where ever you plan to put it. Follow the procedure to add it to the system which is easy and your all set.

Easy to install and works as intended. I was able to hear the beeps on opening and closing a door - the keypads did not beep loud enough, but this allowed me to put it in a better location and adjust the volumn. Highly recommended.

The system is easy to install, reliable and we have pets. Panel is handy to move from room to room if needed as well as the key fab is great to use when you are in your car.

I bought this with the panic button and together they don't disappoint. The siren is loud and the panic button is isn't. Simplisafe calls within seconds. A must buy if you have the updated system.

A great extension for the security system! It definitely amplifies the siren when placed in a good echo-y spot!

This siren is no joke it is loud. It is good to install near a garage door so the neighbors can hear the alarm go off. Most importantly hopefully it does its job too cute the bad people away.

Siren works great with the security system. It is loud. I have had family members accidently set off alarm and this siren gets your attention

This is a great addition to the SimpliSafe alarm system the siren it come with is loud but this is very loud. Great for indoors and outdoors

Bought this as an add on to my Simply safecsystem so I would have an extra alarm. Simply safe is a great, inexpensive security system that works well.

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.

We needed a way to be able to hear the alarm when we are upstairs in our bedrooms with room air conditioners on. This siren is plenty loud enough.

The siren is very loud and should chase the intruder away.

Very loud siren which is great to have. During the test my neighbors came out to their front yards to find out what the noise was all about.

Been waiting for this alarm system to go on sale.Just purchased it and works perfect!

Very loud and perfect for stopping a would be bugler from getting in your house depending on your setup, I would recommend this for anyone wanting piece of mind.

This lil baby is a great addition to the simplisafe security system. It is extremely loud where my neighbors can hear it. Will definitely scare away thieves.

You have to have this if you are going to use SimpliSafe. This is much louder than the regular alarm.

I needed a louder siren for my Simplisafe system. This is it!

The simplisafe catalog says this siren is loud and they weren't joking. You can use this inside or outside and you will try to get away from it.

Have a system at our house, got a system for my parents house. This siren is awesome as it is nice and LOUD!!
