Allso Posted December 6, 2004 Share Posted December 6, 2004 How can I tell if a window inertia device is set-up okay when walk-testing? Is there a rule-of-thumb that you experienced installers use to set them up? I realise its a balance between sensitivity and false alarms, but I have to bang my window frame very hard to get it to activate. Allso Link to comment Share on other sites More sharing options...
Brian c Posted December 6, 2004 Share Posted December 6, 2004 I may get slated for this and they're may be a beter way, but I always use a something that will make a sharp, high pitched tone (like a screwdriver)rather than a dull thud(like your hand). I like to see it take 3 or 4 sharp knocks from the furthest area of glass protected before the shock activates. I like to see it take 1 or 2 of the hardest knocks I can, without breaking the glass, at the closest point on the glass to the shock, before the shock activates. If you don't know......ask.

antinode Posted December 6, 2004 Share Posted December 6, 2004 I don't know what brand of detectors you are using, but Texecom's Impaq Plus will tell you if they are too sensitive. Also, you only want them to trigger if there's any really heavy shocks to the glass or window frame. You don't want some idiot postman setting it off by banging on the window a bit to loud or something. There are testing devices available, but for a one-off (I assume) you'd be better off using else. Just be careful! Trade Member Link to comment Share on other sites More sharing options...

Guest IM_Alarms Posted December 6, 2004 Share Posted December 6, 2004 Perhaps you throw the box it comes in at the window? Link to comment Share on other sites More sharing options...
breff Posted December 7, 2004 Share Posted December 7, 2004 Viper test tool at recommended test points...........................now Ive got one. before that same method as everyone else. I usually bang the frame near to the handle/stay as if its jemmied thats where the force presents itself. The opinions I express are mine and are usually correct!
