Motor Siren Red 1Pc AC 110V 114dB Industry Electric Motor Alarm Driven Siren, Horn Sound Buzzer Alarms Bell for Home, Industries, Stores and Security Alarm System

I chose the siren in the 120 volt option so that I could wire it to my motion detector located near my work van. I installed a on off switch to keep the siren from going off when I was around my van in the evening leaving the motion detector light still working. Prior to going to bed I would turn on the switch that controls the siren. First night it went off multiple times do to night visiting four legged critters. This siren is loud!!!!! Can't comment on it's reliability though. After getting up multiple times the first night do to those four legged critters I've shut it off. But as to how loud it is, it's LOUD!!!!!

Very loud, high pitch, no problem hearing it. Should be used intermittently as it burnt up after being on for about 2 minutes

I have racoons and possums hanging around my front porch. I hooked this up to a remote control so when I see them I can make this siren go off. It works perfect! After two nights. No more pests!!! For a small package it is loud and annoying at the same time. I love it!

Good addition to the security system at my shop. Not quite as loud as I thought it would be

It makes a lot of noise. Which is why I purchased it.

Don’t think it’s as loud as advertised. Maybe other horns were louder than advertised

Very loud makes, one cotinues booooooo sound. Very good to scare people away.

not loud! sounds like a drill motor. im serious! this thing is a waste of money if you are needing an alarm sound
