    Default Bosch Security System CC488 - disable phone line

    Hi there,
    I have an old Bosch security system. I believe the code pad I have is ICP-CP508W and Control panel is CC488.

    I have recently had fibre installed in out house and I need to remove the copper line. Our alarm is not monitored however the old phoneline is connected to it. If we disconnect the copper line it reports a fault with the unit and it beeps away. I believe this must be programmed so it doesn't look for the phone line. Is anyone aware on how to do this? and what the sequence of buttons need to be pressed to disable this feature?

    Any help is much appreciated.

    You will need an installer code to disable the dialler in programming.

    If it was set up for domestic dialling, calling mobiles you could try this.

    To cancel domestic dialling (for example, you are
    moving and do not want the system to continue
    calling your mobile phone), enter the following
    sequence.
    1. Enter your four character Master Code,
    followed by the [2] and [#] keys (for example,
    [25802#]).
    Two beeps sound and the STAY and AWAY
    indicators flash.
    2. Press the[*] key followed by the [4] and [#]
    keys (for example, [*4#]).
    The STAY and AWAY indicators are
    disabled.

    If it used to be monitored then in installer programming,
    Loc 177 would need to be changed to 8
