topgunn Posted April 18, 2014 Share Posted April 18, 2014 Anyone installed a grade 4 system? Is there even a grade 4 panel and devices out there? Substitution detection and range reduction, whattt. Link to comment Share on other sites More sharing options...
matthew.brough Posted April 18, 2014 Share Posted April 18, 2014 Yes, grade 4 devices exist. I've got grade 4 comms in every one if my sites. Nothing complex about what to do for compliance, nor is any grade. It's all in the standard as to what is mandatory at each grade. www.securitywarehouse.co.uk/catalog/ Link to comment Share on other sites More sharing options...

matthew.brough Posted April 18, 2014 Share Posted April 18, 2014 What manufacturer does a grade 4 panel Matt? Pyronix enforcer I don't know of the top of my head. I have a file in my PC that tells me what grade 4 gear is available and from who. It's a while since I looked as it's not the market we sell to. If Adrian's on he might know off the top of his head. www.securitywarehouse.co.uk/catalog/ Link to comment Share on other sites More sharing options...
topgunn Posted April 18, 2014 Author Share Posted April 18, 2014 Got you, so what's the idea behind fitting grade 4 comms in every site? System is as high as your lowest grade , over kill? Just curious. Link to comment Share on other sites More sharing options...
matthew.brough Posted April 18, 2014 Share Posted April 18, 2014 We only signal on IP so we need to poll at grade 4 levels to keep the NAT session alive. GPRS can be flakey and without rapid polling we could never get accurate availability stats. Grade 2 polling could be in fault 23.59 a day and as long as that 24 hour test call is make it will show 100% uptime which is far from the real truth. Only way we can see the real uptime is very rapid polling. www.securitywarehouse.co.uk/catalog/ Link to comment Share on other sites More sharing options...

matthew.brough Posted April 18, 2014 Share Posted April 18, 2014 I've got a webway we are looking at at the minute. Despite 6 cells being available it goes offline for 20 - 60 minutes randomly. No alarms can get through (GPRS only). Both grade 2 and grade 3 polling would report this unit as 100% healthy. Only reason we know it isn't is because we poll it so often. Not that anyone but me seems to care. If someone had a grade 3 comms device in there no one would know there is a problem. If there was an incident it would restore eventually and someone would eventually respond. Not good though. www.securitywarehouse.co.uk/catalog/ Link to comment Share on other sites More sharing options...
matthew.brough Posted April 18, 2014 Share Posted April 18, 2014 Just worked it out. Using 30 second polling we get 1,051,200 polls year on our systems. Meeting grade 2 requirements that would only 365 and and 1752 for grade 3. Big difference. www.securitywarehouse.co.uk/catalog/ Link to comment Share on other sites More sharing options...
GalaxyGuy Posted April 18, 2014 Share Posted April 18, 2014 Is that dual path with landline IP fallback, or dual reporting on both paths? If dual on both paths, how does landline based IP compare ? Link to comment Share on other sites More sharing options...
