Review: 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).
Review: 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.
