Review: Great option for home automation DIY-enthusiasts - I am reviewing the product "5V 12V 9V DC 24V Fire Alarm Siren Alarm Horn Sound Flash Light Loud 120dB" on 21 January, 2024. This is a great option for home automation DIY-enthusiasts for a very loud, very attention-getting siren that can be easily tripped using a smart plug under rules and conditions created in your automation system. A pushbutton on the bottom cycles between the seven available sounds, which I have attempted to describe here to give you a general idea. Sound 1 -- rising-falling, repeating 4x each second Sound 2 -- rising, repeating each second Sound 3 -- high-low (like European siren) Sound 4 -- rising-falling repeating 5x each second sound 5 - rising-falling repeating 8x each second sound 6 - rising-falling repeating 9x each second sound 7 - rising-falling repeating 8x each second, lower pitch All of them are quite loud and attention-getting, and are alarm-type sounds, i.e. none are suitable for general annunciation of non-alarm conditions. The alarm requires the addition of a DC power supply in the range of 5 - 24v, which was not included in the package I received. Operation is simple: when power is applied, the siren blares until power is removed. When the siren is active, it is further supported by a flashing array of 8 LEDs at the top, under a red plastic filter. Although the listing describes them as "super bright:", in my judgment they were only of average brightness; I wouldn't expect them to alert a deaf person, for example, as some strobe alarms are intended to do. The unit is inexpensive and fills a specific need fo do-it-yourselfers, and I am happy to give it my recommendation fo this application.
Review: Works like it's supposed to - This Fire Alarm Siren works just like it's supposed to. It's very loud and you can change the alarm to any of 7 different alarms. I use this as a panic alarm...you can hear this all the way down the block. I set it off to let people think I have a burglar alarm. Keeps people away from my house. I like it!
