datadiffusion Posted July 22, 2015 Share Posted July 22, 2015 Nothing is fail safe, but professional alarm signalling solutions are engineered to make common points of failure relatively easy to overcome, at relatively low cost, and without intervention.

Signalling, yes, acting on that signalling isn't quite as technologically advanced though. Quote Link to comment Share on other sites More sharing options...

james.wilson Posted July 22, 2015 Share Posted July 22, 2015 Dick if it was the best way then insurance cos and the police would prefer them. I've seen sites where there is 50v on the Tel line, dial tone etc but can't be used Quote securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.

sixwheeledbeast Posted July 22, 2015 Share Posted July 22, 2015 Hang on we are comparing two different things here. Signalling and response to signalling are completely different. A dialler can be equally susceptible to response issues as a monitored path. Quote Link to comment Share on other sites More sharing options...

I've seen sites where there is 50v on the Tel line, dial tone etc but can't be used I'm certainly not saying a GSM dialler is the best way, James, far from it. I'm merely playing devils' advocate by saying no system is without potential flaws. Quote Link to comment Share on other sites More sharing options...

As like many threads, SWB, they can go off on a tangent and could be material to start several other threads.Exactly, the response element will always be the weak link regardless of the signalling. .

charlie6 Posted July 22, 2015 Share Posted July 22, 2015 I can see Dick's point regarding response. You can have the finest gprs, dialler, arc etc. in the world. If the response is negative the entire project is worthless (Recent Hatton Gardens Heist ??). Quote Link to comment Share on other sites More sharing options...
Dick Posted July 22, 2015 Share Posted July 22, 2015 Talking of the Hatton Garden heist, how was that concrete allowed in the first place without reinforcements when it was 'guarding' extreme valuables? Quote Link to comment Share on other sites More sharing options...
