went up to Niles yesterday to record one of their refurbed Allertors. Noie a while back caught an ambiance video of these in attack and lately been trying to see if they would repeat that, but each time they just test alert. Oh well, and yes we all know its not wired right and all that so no need to point that out. they test now on 3rd wed and 1st sat of the month
