    Default B450-M and B426-M together on Bosch 2000

    Hi there,

    Can B426-M and B450-M be connected together on Bosch 2000. I am trying to install both but somehow they are not working. When I connect both, my PIR's dont work at all. It looks like there is not enough power to fire up everything at the same time. I am using ICON keypad.

    Also when I take out B426-M out and only install B450-M, my Icon keypad stops working. When I take it out, keypad starts working again. I am not sure what I am doing wrong.

    Thanks.

    The product matrix says up to 2 communication devices. So I assume you can have both connected.
    Why do you want both modules?
    Check that the wiring / plug in lead is correct for module data cable.
    Check that the address setting for the modules is correct.
    I haven't used the B450-M
    Possibly faulty unit if other checks are ok.

    Make sure firmware for control panel and modules are up to date. See section 10.5 of the link below.
