    DSC 1550 Home Alarm
    Today I decided to get the house alarm working in a house. I bought a new battery and it will run the DSC 1550 just fine. The problem is that without the battery the DSC 1550 will not turn on. I went to the local Alarm company and picked up a new tranformer for the 1550 but it still will not turn on the lights to the key pad. Also, I looked EVERYWHERE on the motherboard and could not find a fuse. I was told there might be some tiny fuses in the upper left of the mother board but I do not see one. Another tech told me that some DSC 1550 do not have fuses.

    I am stumped. Could something be blown out on the mother board that is not letting power pass through from the new transformer to the alarm? Wires are in good shape.

    I am not techy enough to meter anything on the board but any advise would be greatly appreciated! Thanks

    Check for correct AC voltage at AC terminals.

    Call me crazy but have you checked your circuit breakers or fuses to your house to make sure the outlet is live? If not, just plug in a lamp or Radio to the outlet the Alarm transformer is plugged into.
