To service an alarm you have to open the control panel to check the battery etc, this is where most of the problems occur. A solid drawn wire will often snap with a clean break, but has often been known to still touch, creating an intermittent fault and so gives rise to false alarms.
Also again down to flexibility if a cable is fixed to say a floorboard the board will move, a solid drawn cable will snap, yes it will take some time, but it will snap giving rise to false alarms. NACOSS as it was then, decided that if something so simple as a multi-stranded cable can prevent false alarms then that is the cable to use.
Agreed stranded is more flexible than solid But as another point.. The individual solid colours used in alarm cable are probably more practical for that purpose than the dual colours used in telephone cable If the solid cores were that fragile and in danger of snapping Then you would have just as much a problem with telephone intermittent faults as alledged alarm intermittent faults!
I suspect it could be because alarm "engineers" who are not actually Engineers, are not capable of correct installation and termination of the cable type they are presented with.
