Using with a DSC alarm system

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).

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.

This item was a replacement for exact same part that lasted years. Original was simple with 2 wires. New one is complicated with a circuit board and 6 wires. As per their drawings and my guesswork i have not got it to work yet. It is well built as was original. I still have hope.

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.

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.

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
