Thread: GC3 Takover System Advice

    GC3 Takover System Advice

    I have decided to go with self installing a 2gig system and finding reasonable monitoring. This is my first time DIY, but paying $33 for a land line and $32 for monitoring seems rather high for an outdated system.


    Need help selecting components, I will be taking over wired sensors from my old DSC 1555.

    2GIG GC3
    2GIG GC3GA-A - Alarm.com AT&T 3G Comm for Go!Control
    2GIG PAD1-345 - Wireless Keypad (Extra pad)
    Encore firefighter ff345 (Take over wired smoke alarms)
    2gig take 345 inside (Take over wired door/window sensors)


    If I understand correctly, the GC3 has built in WiFi so I do not need any type of bridge. Is the GC3GA-A the right cell modem for the GC3 panel? Any other parts I'm missing? I plan to add cameras, locks, etc. later.

    One other question, I don't really understand "programming". If I put up the panels, wire up the takeover stuff, what programming is needed? I assume for the cellular, the monitoring service will provision that.

    The GC3 AT&T model is available.

    The 3G AT&T (3GA-A-GC3) alarm.com GC3 cellular module with built-in antenna runs $120 on ebay, and more dealers will have it shortly.

    Thanks for your help.

    Couple of more questions so I know what to order:
    1. Looking at the DSC 1555 manual I have 12VDC at the current panels. Would it be okay to use a DC-DC converter there to get 16VDC / 250mA? Or is it recommended to just use the transformer? (would prefer not to)
    2. I see in the manual, the unit has an internal siren, but I also have a loud hardwired siren in the attic. Is it possible to use it?

    For question 1, are you looking to do this for power to the takeover switch or the GC3? If the latter, I would use the transformer, as the DSC panel is likely wired to a wall outlet for regular power, but also battery backup if the power goes out. I am not sure how the GC3 woudl react to the battery backup from the panel? Maybe I am reading your question wrong though.
    For question 2, you shoudl be able to wire the siren to either the takeover switch or the GC3 (it has a couple hard wire inputs), whichever is easier.
