Easy to install and worked right out of the box
Easy to install siren and it worked with my Vista 20p system with no issues. Sadly, it looks like this siren is discontinued. For some reason, I didn’t get any instructions with the box. So for anyone that needs it, you use either the yellow (positive) and black (negative) or red (positive) and black (negative).

Works as advertised.
Replaced 20 year old indoor alarm that just stopped working. Easy hook up. Tests fine and is loud enough to make anyone in the house not want to stay very long. It’s for any standard 12V alarm system.

The picture drawings are not real clear.
This one can be confusing to some It has two black, yellow, and red wires each. It has its own siren driver. The two black, yellow, and red wires are the same each. You should not have to add a end of line resistor.

Works great
I did not actually buy this product to use with a dsc alarmInstead I made a circuit with an arduino and the siren and it works perfectAlthough the first shipment of the product was broken

It Works, It’s loud. What more do you need?
This worked perfect with my DSC Neo Alarm system. I retrofitted my house with a Neo from a garbage brinks system and the siren from the brinks wasn’t compatible – this one fit the bill.

Alarm Voice
Have a 30+ year old alarm system that lost it’s voice. Found the OEM replacement part on Amazon at a great price and in 2 days had it back working.

stupid loud
I thought that it would be like those cheapwindow alarms but I was wrong when I tested this device I was amazed of how loud it was I can feel the sound waves from 6 feet away I would say this is as loud as a circular saw or louder
Frugal but fair –
