    Hi abes216,

    If you have a 6 zone panel it is on the bottom row beside the keypad, if it is the 8 zone panel it is on the right side above the keypad. You should see the 12v output clearly marked + -

    I am nearly certain that the transformer in the HKC panel is a 220V/18V AC. So the supply to the board is 18V AC and is then rectified on the board to 12V DC
    I am not sure on the polarity of the two connectors but you can easily find this out with a multimeter

    Hope this helps

    Hello,

    Can I get a 12v dc power supply for a door bell and chime from the panel?

    Moved to electrical.
    Should be OK to connect to auxiliary 12vdc.
    What is the power consumption of the unit you want to connect?

    12vdc.

    I bought an intercom and needed to wire four cores for it's voice signal at the hall door. Was running a wire then to the chime.

    I drilled through the two door bell wires, can't get at them to fix. I was hoping to use for these to power to the intercom. Now I'm planning to use two other cores to power it and the chime happens to be right beside the HKC panel, so loop that in too. I assume using alarm wire is ok for wiring in to this 12vdc.

    Should have paid the extra and bought a wireless intercom!

    For AC you will need a seperate power supply. That can not be connected to the alarm panel.

    you have to sleeve the ELV cable(intercom/bell wire) if you bring it into a din-rail mounting trafo

    throw a bit of 3-core flex covering over it
