Hello,
I have just installed a Gartdec Eurosec CP8L, it has seven dualtec detectors and no contacts, that was the way it was prewired. Turned the system on and everything worked fine for about five minutes. Half way through programming, the RKP crashed and and found out after that the PCB had burnt out.
Fitted a new one and the heat sink on the back got redhot within two minutes. All the PIR's work OK and the RKP is only three feet away from the panel???????
Thanks for reply but i have found the problem. It seems that the sound bomb i installed needs to have a link cut in the back to make it work, one of three tones. It was supplied with no paperwork etc to say this. Cut a link and all is now fine.
depending on your technical knowledge, check the cabling from the keypad to the panel and confirm you have shorts on the cable, check all terminations are clean in the panel too. Check voltages on keypad, detectors and power from the auxillary supply from panel. should be approx 13.58vdc - good luck
