Hi anyone who can advise on this fault .
recently had electrical problems here ,where the supply voltage has dropped as low as 90v ac .
though the wiring centre has back up battery the external sirens are held in .
the rkp is showing the lcd lit up green back ground when i touch any buttons and no sound lcd Accenta G4 rkp F131 -01-100 .i know what it stands for ,but the rkp is un functional ,the day and power lights are not lit .have tried power down and link set - tamp procedure but still no avail .
The engineer manual dosen't do a very good Fault finding guide which is why i am here .
would appreciate any imput
