Guest cheeky monkey Posted April 19, 2005 Share Posted April 19, 2005 this may be a silly queston to a lot of installers but, iam about to install my alarm (scantronic system) in my home but all surfaces on the outer walls are stone (very uneven)- how do i go on mounting the external sounder on this sort of surface as it eill not sit flush to the wall as it would on an average brick wall and didnt want to start cutting the font off the stonework unless absolutly nesescary(spelling) in advance Link to comment https://www.thesecurityinstaller.co.uk/community/topic/5840-bell-box-on-stone/ Share on other sites More sharing options...
Guest Posted April 19, 2005 Share Posted April 19, 2005 You could either mount the box onto a flat surface on the stone, such as a piece of heavy duty perspexy stuff, (can't remember the specifics atm, brainfade, RICHL will know ), or a piece of steel cut to the same size as the box. The other option is as you say, flatten an area of brick for the box to go on.

ian.cant Posted April 19, 2005 Share Posted April 19, 2005 Yeah, usually you can find an area thats flat enough to get all the fixing points to touchdown so to speak, otherwise its find a backboard.

Guest Posted April 19, 2005 Share Posted April 19, 2005 Fixing the bellbox isn't usually the problem, it's getting the tamper spring to touch something and getting it square enough for the cover to fit without forcing it. Sometimes you fall lucky and manage to get it straight onto a suitable bit of stone.

CompostCORNER Posted April 19, 2005 Share Posted April 19, 2005 I hope it is stone and not stone effect cladding. I came a cropper with the latter once and had a nice 12" x 30" x 3" thick piece of simulated sandstone commit suicide from the side of a house when my bellbox drill bit made contact with it. Many years ago likes but one event I'd not like to repeat.

Regards the question though, I recently had a similar problem and just used my SDS drill with rotary stop and a very wide, flat chissel bit (about 6"). Made a lovely smooth stone back. Some bellboxes are better than others - I mostly use a metal box with a perfectly flat back so usually not a problem, except on the houses using local stone, etc... Much quicker than flattening it by hand anyway! Stu. So, I've decided to take my work back underground.... to stop it falling into the wrong hands Link to comment https://www.thesecurityinstaller.co.uk/community/topic/5840-bell-box-on-stone/#findComment-49547 Share on other sites More sharing options...

Deltaseven Posted April 21, 2005 Share Posted April 21, 2005 cqr bell box? 49568[/snapback] Don't! We used a lot of them in the past - and now I seem to spend my life changing them because of random bell tampers (OK - maybe a little bit of an exaggggggeration there!). Now we use the Texecom boxes with the ingenious "patented-hole-in-a-piece-of-plastic-tamper-system", and have no problems! Also, the tamper switches are inside the SAB, and don't get wet - unlike the CQRs, which go high resistance after a while. Rant over.
