Chorlton Posted October 9, 2008 Share Posted October 9, 2008 many moons ago i attended an intruder alarm in the basement level of the antiques market in Isilngton, while there and before i could get my toolbox open the fire alarm tripped.don't know what siren it was but i simply had to retreat due to the sheer noise it made, my skull and jaw bone were viabrating from the sound pressure, seriously painful experience. might be down to reflected harmonics from the walls etc, like when you the SAB gets put on the board above a shop doorway, just seems to increase the noise level produced x 3 times regs alan You got confused it was - http://uk.youtube.com/watch?v=9i1QAtET0ok&...feature=related Link to comment Share on other sites More sharing options...
arfur mo Posted October 9, 2008 Share Posted October 9, 2008 You got confused it was - http://uk.youtube.com/watch?v=9i1QAtET0ok&...feature=related but is that geezer at the start of the clip trying to stop it with a pencil? just think -if only the Germens had worked that sabatouge out - we could have lost the war regs alan If you think education is difficult, try being stupid!!!!

Brian c Posted October 9, 2008 Share Posted October 9, 2008 wb brianYou always needed to group the max independantly of the keypad as it is in effect a seperate device built into the keypad. Gives more flexability as you can have the keypad on all groups, the keypad sounder on other groups, and the max on seperate groups again if needed. mate you don't have to do it on the non dimension panels. Just program a fob as group 7 and you can use it any keypad by default, but the dimension panels with option 69, you have to assign the alarm group function as described above If you don't know......ask.

I remember showing a lad why internal spks have +ve & -ve. We fitted 2 in an office block(1 on landing, 1 in gnd well). Fitted as you should and set em off. Then swaped one over and set em off. Must admit I was surprised at the reduced level. 180 degreees out of phase I said. I wanna be a plumber he said. Link to comment Share on other sites More sharing options...
jontawn Posted November 2, 2008 Author Share Posted November 2, 2008 Just incase anyone was wondering about the klaxon sound bar we used, its a bit loud! ... they certainly make enough noise to annoy any would-be intruder. Although not as loud as I thought they'd be, the home owner is pleased with it though. i'm not sure what I expected, but i think i hoped it to be a little more unbearable in terms of SPL but with it being transducers, I guess it was a vague half-expectation. Would I spend my own money on one? yes! certainly a lot better than some of the other things i've heard!

Jonathan These are great, i know them by the name of an inferno bar! if its not as loud as you thought then check you've taken the jumper off to pump up the DB from 120 to 124. Also i've noticed by forgetting the batteries incased in the unit, try connecting to a much larger 12v batt!! much better!!!!! Link to comment Share on other sites More sharing options...
norman Posted March 8, 2011 Share Posted March 8, 2011 2008, his batteries will need swapping out soon! Nothing is foolproof to a sufficiently talented fool. Link to comment Share on other sites More sharing options...
