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

Why We Needed It After I accidentally set off our SimpliSafe alarm, the base station barely made a sound and my wife and kids did not even wake up. That was a wake-up call for me, literally. I knew we needed something louder that would actually get everyone’s attention in case of a real emergency. Setup and Installation Setting this up was really easy. I just opened the SimpliSafe app, added the siren, and it connected almost instantly. The app makes it straightforward to assign it to the system and it even lets you test it right away. Mounting it on the wall was a little tricky if you tried to rely on the adhesive. It did not feel secure enough, so I went with the screws included in the package. Once it was screwed in, it felt solid and I did not have to worry about it falling off. Performance This thing is seriously loud. When we tested it, it was impossible to ignore and I can say with confidence it would wake up anyone in the house. The tone is sharp and high enough to be heard through most doors and rooms. It adds an extra layer of peace of mind compared to relying on the base station alone. Pros Easy to connect and manage through the SimpliSafe app Loud enough to wake up everyone in the house Small and unobtrusive once installed Works exactly as expected Cons Adhesive was not great for wall mounting Might be a bit more expensive than some non-official options, but the reliability is worth it Bottom Line If your SimpliSafe alarm is not loud enough on its own, this is a must-have. It is easy to set up, performs exactly as advertised, and will actually alert everyone in the house. I feel much better knowing that if the alarm goes off at night, it will not go unnoticed.

This siren is loud, easy to set up and connects with the system. Small and blends in well. Functions as described.

Wow this is really loud I highly recommend this. Very easy set up.

The Simplisafe support page says how to test this: ========= - Place System Into Test Mode - ... press the button on the top of the Extra Siren. You’ll hear the Base Station announce, “Siren” to confirm the test was successful. NOTE: The Extra Siren will also emit a loud beep during this test. Please be sure to protect your ears, as the Extra Siren is equipped with a 105dB siren. ========= To me, that implies that the siren will beep as loud as the siren alert sound. But it doesn't. To actually test the siren's alarm sound, I had to call their customer support people who armed the system in practice mode and then had me trigger an alarm. Then the siren sounded fully (and very loudly).

One of my main concerns with Simplisafe was the potential for smash and crash. You can look it up on the internet, it is a big concern with alarm systems. The thief finds the base station during the entry delay or shortly after the alarm goes off and smashed it before notification can be sent out. Even though alarm sirens are loud, usually it is only inside the house and is unlikely to draw attention with the doors and windows closed. I added two of these sirens and hid the base station. One siren is outdoors and the other is indoors. When the alarm goes off, the base station and both of the sirens will be sounding loudly. It would be hard to pinpoint the location of the basestation with multiple sirens sounding earpiercing noise. The external siren will attract attention to the house and no thief would want to stick around. I paired the sirens, cleaned the mounting surface with alcohol, and the siren mounted securely.

Love this works great

I have 6 of these sirens. Three inside and three outside of my home. Sufficient, I believe. One of them just died for no apparent reason after three years. So I will be replacing it immediately. When operating a Simplisafe system in a very large home, there are challenges in terms of all sensors reaching the base station. It will require some effort and take some time to get it right, or else you'll be getting some false alarms or non-connection alarms at inconvenient times. Overall we have been very satisfied with our system. The sirens are quite loud, which is a good thing.

This thing is LOUD! Thank goodness the volume is adjustable.

Didn’t work. Wouldn’t link so sent back faulty. via UPS... had confirmation of sending but shipping back to the USA. So assume this will take ages

I tested this and my teeth hurt it was so loud. I expected it to be louder than the base unit but more than expected. You can barely stand being in the same room when this goes off. This is great to sue away intruders.
