Ok. Thanks.

Would the lower IR setting on a megger be acceptable - mine is 250V? Or would you use the ohmmeter setting on a multimeter? Thanks

Hi All Is there a protocol for testing the effectiveness of alarm cable. I have a property which has cable already in place but no alarm and the owner wants me to wire in an alarm. I have no idea how old the alarm cable is or what state it is in. I am familiar with the testing of domestic cable using continuity and insulation resistance testing. Do I just do the same thing for alarm cable to test if it has deteriorated over time? If so what sort of measurements should I get? Thanks in advance for your help. Pete

Thanks guys. Feel kind of reassured that I have done the right thing. Will bell out the cables as I will install a wired system if the cables are ok.

I have kind of worked out the cost in my head for faffing about trying to work out what is up with this system to maybe end up fixing it with some aged new part scrounged off the internet or a second hand part to end up with a working 15 year old system. The customer I think is kind of resigned to replacing it.

Meaning? It is bug()£& and a new system is the best solution?

I would have thought that a healthy supply to the keypad would rule out wiring issues. Even if data transmission is damaged surely the keypad would operate if only to generate nonsense. If this is the case surely a new system is in order.

Hi all I am trying to problem solve a problem on a Gardtech 800 alarm system for a customer. There are two key pads that both appear to be dead function wise apart from an orange light on one which is a wallet sized number pad and a green back light on a larger number panel. I have checked the following. Mains to control panel. correct output from transformer. the battery is new and knocking out a healthy 13V the keyboard outputs on the PCb are also 13V the pcb is also has a steady 13V input. I have removed the keypads and confirmed they have 13v power supply. i have removed the fuses on the main board and confirmed all of them are functional. the keypad screens are all blank despite the orange light on one and green tinge on the other. Buttons do nothing. Screens show nothing. We we have a had a few power outages recently and wondered if maybe we had suffered some power spikes or surges that might have affected the circuits. Any advice would be gratefully received. Thanks Pete
