weesidney Posted February 3, 2009 Posted February 3, 2009 Hi guys hoping someone can shed some light on this one, I've got a Galaxy 500 V1.25 installed in a large business, 33 modules with 4 keypads.I am aware that one of the buslines has been overloaded with modules and as I watch the leds on the rios etc I can see them change flash rate - poor comms, I have re-routed some modules onto different buslines and it has cured other problems I had like a huge delay in the panel seeing zones opening or closing on that busline. The problem I have is that regardless of which line a keypad is on I get them freezing up and not accepting any codes, when pressing any button there is no change to the display (no stars appear) Any ideas? Diagnostics shows 100% voltages are good Galaxy suggested fitting magnetic coils to suppress any EMF (only suggested today so I haven't tried that yet) I'm leaning more toward looking at the main panel being faulty as the problem isn't reserved to one busline but all the lines have keypads on them. wee sidney

james.wilson Posted February 4, 2009 Posted February 4, 2009 does this happen mainly on line 1 or on all lines. SOunds to me like you have serious data issues, either cable or bad modules. COuld even be the panel had a 500 with a weak line before securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.
weesidney Posted February 7, 2009 Author Posted February 7, 2009 Hi guys, in response to some questions, I myself am a service engineer, the job was installed to an extent by installation engineers, but because of the size of the site I am finding out that there were numerous people involved therefore when I ask questions about equipment locations, wiring runs. All I get back is "I wasn't involved in that bit" The problem has been escalated within the company and I can see two engineers being sent to site to check every module for screen continuity, connections, cable runs etc. The company I work for have a seperate Installation and service division so once the job is installed it becomes the problem of the service department - which makes for some poor working practices on the install side - it's a mind set of get the job handed over and they can forget about it. Thankfully that is becoming less common and the company has evetually realised that this working practice and mentality is costing the company money on return visits from service engineers. Thanks for the responses guys I just wanted to check I wasn't missing something obvious or if someone out there had had the same problem wee sidney
