i added this to my SimpliSafe home security system. So, I now have a siren at the front and back of the house. It is pretty loud and would definitely deter someone from staying in the house for a long time. The only problem that I have with SimpliSafe... and it is not related to the siren... the base unit is not loud enough to hear when a door is opened. And when a door is closed it does not chirp again. I wish that SimpliSafe offered another speaker that linked to the base and you could place the speaker in another spot in the house. I would also like the door to chirp when opened and once again when closed... it would let you know that the door is properly closed.

This was a great addition to my SimpliSafe setup. It is easy to set up right out of the box and pair to the system. It is definitely loud enough to get your attention no matter where you are around the property. I love that you can set it to chime with the base station, but the only thing I do not like about it is that there is a delay between the base station chime and the siren chime. One other thing I would like to see on future products is stronger adhesive, this fell off our wall twice after install.

Extremely loud and does exactly what is needed. Easy to install and setup.

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.'

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!

Added this siren to my security system from SimpliSafe. Much louder than the one from the main base. Highly recommended and easy to setup like all their other products. A+

I own the simple safe system that works great! However, the alarm that came with my package, the cone, wouldn't scare a small child. I read all the reviews and was convinced this was necessary. I is really loud with the 2 sirens hopefully I will never know that it scared the potential perpetrator off. This system is a snap to install and the staff are wonderful to deal with if you have trouble. Better to be safe than sorry!

I bought the SimpliSafe unit and it works great, but the alarm the base station gives off is not very loud and wouldn't scare an intruder. You MUST get one (or more) of these sirens. They are so loud, it hurts. I'm kind of surprised that one of these isn't included with the main system, as I feel it's necessary to make it feel like you actually have an alarm that would scare away an intruder.

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

Connecting this to my alarm was very easy with no issues. Mounted it outside and tested the siren by setting off the alarm. It is VERY LOUD and can easily be heard by your neighbors. There was about a 2 second delay from when the base went off till this siren started and as soon as I disarmed the base this stopped. Works great and highly recommend!

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

It was a excellent addition to my SimpliSafe system. The siren is very loud and you can place it anywhere in your house, once you log it in to the SimpliSafe tower, which is very easy.

Very simple to install, no wires required, and really gets the job done. I purchased this for a home that's under construction. The simplisafe home station serves as a speaker, but it's not very loud. And in the event of a burglar breaking in, they can simply disconnect the base station and/or take out the batteries to silence the alarm. This alarm, on the other hand, can be placed outside in a hard to reach place (which is exactly what I did), and can be heard by the whole neighborhood. It will definitely send thieves running.

Michnlouder than the previous generation. Easy to install accessory

The siren is very loud and would definitely draw the attention of others. It is also easy to hear from any room in our place. You can use multiples if you have a large home or multiple floors.

I added this to the system I purchased four months ago, replacing my ADT system. The siren built into the startup system is not very loud. I put this on the ceiling of my covered front porch close to the front door to let any intruders know they set off an alarm and the neighbors know it. No issues, it can be heard in the house as it is very loud.

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.

This siren is really loud it can make your head rattle. Great for intruders, the sound is deafening.

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!
