DC9 to 12V Wired Strobe Siren Red Light Sound Flash Buzzer Siren Home Security Alarm System Electric Security Siren 110dB12V DC

I got this to use with my Hubitat smart home system, no this is not smart by itself. I install this outside on my ceiling over my porch so I could have an outside siren when my alarm would go off. I use it with a 120v to 12v power supply and have that plugged into a smart plug. I have it set up so when my alarm goes off it turns on the smart plug which turns on the siren/strobe. And boy is this siren loud! The plastic housing is pretty cheap and cracked a little while I was screwing it to the ceiling. Time will tell how long it last but it's fairly protected where it's at. Overall this was one of the cheapest siren/strobes I could find, I didn't want to spend a lot of money for something like this but it does what I need it to do. Pros: It was cheap Easy to wire up Has strobe and siren Cons: It's cheap (cracked while mounting it) Not weatherproof

Works great as alarm system for a high water pump.

Worked as expected - loud and bright — very happy with value for the money. I put it outdoors but protected under the eaves of the house, to help get attention for an alarm system. Not loud like a big alarm system siren, but louder than a smoke alarm.

Would have been nice if the hole pattern fit a standard outlet box, but it doesn't. Also wish it was a little more weatherproof. It is loud and works as advertised.

I got this buzzer to wire into a "fire alarm pull switch" which I installed in my son's outdoor playhouse. It works well, and even outside it can be heard even across the street !
