    Default Das nx 12 no power light

    Hello

    I have a nx 12 system once when trying to arm a beep beep started

    The power light was out

    However there is power at the Gpo

    I have replaced the battery and power supply.

    The battery will power up the unit,however the power light still doesn't appear.

    Any thoughts would be appreciated

    Did you replace the plug pack with a 16volt to 18volt AC not DC plug pack, with the plug pack power point switched on, is there around 16 volts on the AC pwr in terminals on the board, the modern plug packs have an internal fuse, and if you shorted out the flying lead wires from the plug pack you may have blown the int fuse and will have to get a new one, if you dont have a multimeter with the plug pack on and connected , if you remove the battery and the keypad shows no sign of life your plug pack might be cactus, you say the pwr light dosent come on , do the sensors light up or the ready light come on
    the beeping on arming is advising a time fault or system fault i.e. no ac pwr
