Rated 3.7 out of 5 by 3 reviewers.
Rated 5.0 out of 5.0 by Extreamly loud I purchased this siren as an add on item to my Security Man AirAlarmIIE home alarm system . Out of the box this item has performed as described. I accidentally set my alarm off he first day I got it and my neighbor "two houses down" came out to see where the noise was coming from. November 8, 2013
Rated 5.0 out of 5.0 by A must buy I hung mine up outside and it is loud. You must add this to your wireless system. January 21, 2015
Rated 1.0 out of 5.0 by Scary at Best! I am sorry to say this device failed, failed, failed. It was not even installed before it started going off at random times. We tried turning it off, but the rechargeable battery prevented that. The base was disconnected and turned off, and still the alarm would go off at random times! This thing is super loud, but the strobe light did not flash. I guess that is a good thing, though the piercing siren at random times was bad enough without the light. This device was returned.
