The GC3 is 2GIG's response to modern home security. From the makers of the first, and most disruptive self-contained security system ever built, the now-famous Go!Control 2, the 2GIG GC3 continues the tradition of user-centered security systems that are easy to use. This top-of-the-line hardware features some of the most innovative features ever seen on a home security system, rivaling any top-brand that exists in the space. Also worth mentioning is the incredibly close integration that 2GIG has built with Alarm.com, which allows users to control the system from their home or computer with incredible ease. The intuitive alarm.com app makes home security fun, simple, and very easily navigated by an end user which makes it perfect as a DIY panel.

The 7 inch capacitive screen makes for a responsive touch screen with large buttons so that anyone can use it. In addition, the unit has features that were loved on the old Go!Control such as one-touch arming. At a mere 1.25 inches, the GC3 is one of the thinnest high quality all-in-one system to have been sold to date. It's small profile means that it will sit on even the most discerning homeowner's wall without being an obtrusive eyesore.

Like the 2GIG Go!Control that came before it and unlike Honeywell's products, the 2GIG GC3 does not work without a cellular antennae installed in the unit. If you are in an area with special needs regarding wireless, you can choose between having the panel communicate over AT&T's 3G network, Verizon's CDMA network, Verizon's LTE network and Roger's GSM network (if you're in Canada). The snap-in radio antennas are easily installed without having to fully open the panel. There is no tool required, and it can be replaced if it ever goes bad without breaking the panel.

Like its Honeywell counterpart, the Lyric Controller, the GC3's firmware is upgradeable, which means that you will be able to enjoy the features of the system today and many more to come. This allows new features to be added to the system in just a few touches which means that the hardware might get older, but the software will ensure that your system is as up to date and running smoothly. To update the panel, one can use a USB port for fast on-site updates, or over the air with the right equipment.

While old security systems often gave end users a few zones due to hardware limitations, with the benefits of moving toward digital sensors and digital communication, modern security systems give end users more zone options. While Honeywell's L5210 and L7000 allow 64 and 79 programmable wireless zones respectively, the 100 wireless zones available for programming (the 2GIG Go!Control had only 60 wireless security zones). The panel also comes with the ability to program 32 key fobs, which is 8 times more than the GC2. Additionally, the GC3 can control up to 4 keypads, has 2 open collector outputs, a Bell Output for an external wired siren, as well as 2 wired zones in case you would like to use a few pre-existing wired door or window sensors. An additional feature that the 2GIG GC3 has that is also worth noting is the ability to add 100 users and to name them. While most systems, such as the LYNX Touch Series panels from Honeywell, do not allow you to name your sub users, and merely assign numbers to them, the GC3 actually allows you to add names into the panel that will let you keep track of exactly how the system is being used and by whom.

anyone having issues connecting to latest AT&T fiber router via WIFI please?
Hi Carl, Unfortunately, at this moment we do not have it listed on the site but I did send a request and will let you know when we do. In the meantime, if you are able to find it elsewhere online, you can certainly order it.
I couldn't find the replacement battery for the 2gig gc3 panel. Do you sell it ?
The system can interface with Amazon Echo through the Alarm.com service. The system will need to be monitored to use this integration.
Is the 2GIG system compatible with Amazon Echo Plus Hub?
There is an internal antenna for the built-in wireless receiver that's used to communicate with the wireless system sensors. Usually though, if someone is asking about an antenna, they are asking about the optional cellular communicator. If you wanted to use cellular alarm communications, you'd need to add an extra cellular communicator. There is an AT&T version (https://www.alarmgrid.com/products/2gig-3ga-a-gc3 ) and a Verizon version (https://www.alarmgrid.com/products/2gig-cdmav-a-gc3 ) and both have built-in antennas. If an external antenna is required, you could use the ANT3X 10" in-wall antenna (https://www.alarmgrid.com/products/2gig-ant3x ) or the ANT2X 10' antenna (https://www.alarmgrid.com/products/2gig-ant2x ).
Does this come with an antenna?
I'm not familiar with the PiSector system but typically the 2Gig GC3 panel supports 2Gig and Honeywell wireless sensors so I would assume you'd need all new sensors. Also just to clarify, while the GC3 does support a Verizon communicator, to get any remote access an an Alarm.com account without any central station monitoring being involved. The $25/month rate does include the cellular data charges that we pay to Alarm.com on your behalf though.
I purchased a DIY home security wireless GSM system PiSector GSO8 but found out to late that my area has no GSM coverage but does have CDMA coverage via Verizon. My question is if I purchase your Verizon GC3 panel will it be able to pair with the sensors I have and can I name zones my own names? I prefer to do my own monitoring without relying on a third party via cell phone app to arm and disarm the system remotely and like the additional home automation features this panel has!
Yes the nest thermostat is compatible with Alarm.com. Generally speaking Alarm.com offers more third party integrations. If that is a priority upgrading to a GC3 is solid move. AlarmNet is releasing a new web version of TC2.0 in the coming months. So it will certainly be better than it is now. However I think Alarm.com will remain the leader in third party integrations for quite some time.
I saw online that this will be compatible with other products such as nest through alarm.com, do you know if this is true and what else it's comparable with? Do you have any information about the differences between t.c 2.0 and alarm.com. I'm about over t.c. 2.0 and am contemplating purchasing another control panel running through a different system to get away from it.
Jeffrey that will be a question for Frontpoint. We are not familiar with which panels they support. We do offer no contract monitoring plans that should be very competitive with Frontpoint's plans at https://www.alarmgrid.com/monitoring. Feel free to email us at support@alarmgrid.com with any specific questions.
Will the GC3 work with Frontpoint?
Yes, you should be able to tie in those Z-Wave devices to the GC3. However, you can't have devices learned into more than one Z-Wave controller unless you use the secondary controller feature. We don't limit the number of Z-Wave devices you can have enabled with our Gold plan.
I just bought GC3 and i have existing lot of in wall Z-Wave dimmer, and Schlage BE469 door lock and currently using Samsung smart things. Can these thing can work on GC3. Also what is limit of z-wave device with your gold package and alarm.com
We don't have an official list but most Z-Wave lights, locks and thermostats should work. Do you have any specific devices you were hoping to use? If so, let us know and we should be able to confirm if they work or not.
What Z-wave items are compatible with this panel. I have not been able to find a list.
It was a change made in the GC3 for some reason. We're not sure if later firmware versions will allow local Z-Wave rules and triggers or if the GC3 will always require Alarm.com service for that type of functionality.
Thanks for the info! Just so I understand you correctly, the "Run" option I saw in the GC2, was that because the unit had Central monitoring or was it depericated in GC3 (avialable in the GC2 even without CM) and is only avialable with CM?
You can't setup local Z-Wave triggers or rules to run scenes on the GC3 at this time. You would need alarm monitoring service going through Alarm.com which we offer online at https://www.alarmgrid.com/monitoring for that type of functionality. The only compatible wireless keypad at this time is the PAD1-345 (https://www.alarmgrid.com/products/2gig-pad-345 ) but we do expect 2Gig to eventually release a wireless touchscreen keypad version for the GC3. We are still waiting on 2Gig to release the first firmware update for the panel, which should open up the WIFI option. You should have the latest firmware now since they haven't released any firmware updates as of yet.
I recently purchased the GC3. While going through some of the installation videos (you guys do a great job, btw. I found the videos very helpful. Many thanks!), I noticed on the previous model there was a run setting in order to trigger or automate the scenes. I am unable to locate that option on my GC3. Was it removed, or do I need to do something in order to have it appear in my menu? Another question I have is other than the keypad is there another remote console such as the TS-1? If I understanding is correct, the TS-1, although it works with the Gc2, will not work with the GC3. Is this correct? If so, what's the alternative? Speaking of the remote keypad, is there anyway to include a status light to let one know the system is armed/disarmed? I purchased the GC3 thinking that the WIFI was already on. After reading this blog, I find out I have to wait for a firmware update. Any idea when the next update will happen? Oh and what is the latest firmware version?
Is that a custom "wedge" you used or a specific device? If it's not a custom thing, do you have any model numbers for ones you've used that work? I'm sure that would be helpful for others using the Skybell HD
Be sure to plan ahead before you buy the Skybell HD. You may need a digitial doorbell adapter, a "wedge" to make the camera point up and/or a doorframe adapter to make it properly fit where your original doorbell is now.
The Skybell HD (https://www.alarmgrid.com/products/skybell-hd ) is compatible with the Alarm.com service that allows you to remotely arm/disarm the system from a smart phone or computer and receiver text/email alerts from the system.
Is there a compatible doorbell camera like what vivint offers that will work with this panel?
It's possible with our Self Gold plan available at the bottom of our sign up page at https://www.alarmgrid.com/monitoring but it's not possible to get alerts without some level of service setup with a company like us. The Self Gold plan would provide you with Alarm.com interactive services so you could arm/disarm the system remotely and receive text and email alerts from the system without the central station service being active. You would need to have a cellular Alarm.com module installed in the panel as well.
Hey Sterling..... I have a Resolutions Products RE208 takeover module on the way for the 8 old hardwired sensors in my shop about 150 feet from the house...... I was thinking of getting a GC3 panel and wireless door sensors, and Pet immune PIR's for the house and one for the garage.... .for now.... I wanted to use it for now as a stand alone system..... but be able to monitor it from my cell phone... is this possible without a Central Service ( for now, until I get the system fine tuned and any false alarms cured)..... Possible? Yes? No?
Have you considered the Honeywell Lyric system (https://www.alarmgrid.com/products/honeywell-lyric-controller )? It is available now and the SiX Series sensors that are encrypted are available now.
I don't have the GC3 panel.
We've been told by 2Gig to expect them Q3 or Q4 this year. Do you already have a GC3 panel?
When will the encrypted sensors come out?
2Gig has not yet released firmware update to enable the WIFI functionality of the GC3. If you plan to have your GC3 monitored, the lack of WIFI shouldn't really matter though as you'll need a cellular based Alarm.com communicator to have it monitored anyways.
Hello Sterling - Just checking back in to see if 2Gig got the WIFI working yet. If not, what do you recommend in terms of an alarmgrid provided kit. I would like an all-in-one panel, 3 door/window sensors, motion sensor, and with smart home feature capability such as electronic door lock. The 2Gig GC3 is attractive and sounds feature rich, but it seems less capable without subscriptions and a badly needed firmware update. Thanks, Kevin
Yes, once you are active with Alarm.com service (which we offer with no-contract plans available at - https://www.alarmgrid.com/monitoring ), you'll have better control of your Z-Wave devices. Also, we do expect 2Gig to release a firmware upgrade for the GC3 at some point to include functionality for the alarm.com thermostat and image sensors but we don't have an expected release date yet.
I ordered my GC3 panel and installed it with no issues. Set up was fairly easy and I do appreciate the two wired inputs on the panel. Question: Since this system must be used with Alarm.com (or at least that's what I'm being told), will the next firmware update include provisions for the Alarm.com thermostat and Image sensor? As of now, they are incompatible (per Alarm.com). 2Gig may have some nice hardware features, but programming automation & security scenarios seriously frustration me with the incredibly limited device/scene/control programing features. If they would add "IF, AND and THEN" statements, then this would give the system some great user features.
At this time, it's still not available. I believe 2Gig runs quarterly firmware updates and the panel came out in February so we expect it sometimes this quarter or next.
Hello Sterling. Been a little while since your reply and I am checking to see if the WIFI functionality has been fixed in a firmware update? Thanks, Kevin
Okay, so it wasn't a GoControl Vivint panel then? That would further verify that they were using proprietary sensors. If you search DW11, there's very little information which also seems to show that these are special sensors that only work with a Vivint system. Let us know if the regular 2Gig sensors work with your system as I certainly wouldn't expect you to have any issues using regular 2Gig sensors.
Those are most likely proprietary sensors for the Skypanel. You could call and ask Vivint? Those are not universal 2GIG part numbers so that is my guess. You can use any Honeywell 5800 series sensor as well. Just FYI.
The DW20R shuold be compatible as that is a valid 2Gig part number. I'm not familiar with the DW11 sensors though. What Vivint alarm control panel were you using? I am wondering if you had a special panel that uses special senors.
Yes, that is true. Most professional all-in-one wireless systems won't come with a transformer wired to the panel as most manufacturers are expecting an installer to put the panel in and they all figure the installers will have a spool of wire on their truck. The AC2 (https://www.alarmgrid.com/products/2gig-ac2 ) is a transformer with a wire attached or you can get a length of wire from Home Depot or Lowe's to wire the transformer to the panel.
Just want to high light that the unit does not come with anything to connect the transformer to the panel. In order to turn it on, one needs to order the AC2 plug just for the barrel connector or get some 16/2 cables and split them. I have to say I am caught by surprise and I am really puzzled by why 2GIG decided to sacrifice user friendliness/experiences for a couple dollars...
The GC3 does have integrated WIFI and Z-Wave modules but the WIFI won't be functional until a future firmware update. I don't know if 2Gig has a list of compatible Z-Wave modules but typically any Z-Wave light, lock or thermostat will work with the system. The cellular module would require a service plan that includes cellular. You don't need to pay extra to your own cellular provider. You can view our available no-contract plans online at https://www.alarmgrid.com/monitoring and our Gold/Self Gold and Platinum/Self Platinum plans include cellular. The system comes with a transformer but you would have to supply your own wire or use the AC2-PLUG - https://www.alarmgrid.com/products/2gig-ac2.
I understand a cell card is required for remote monitoring, but does the GC3 come with wifi and zwave cards installed? Is there a list of tested/compatible home automation devices (locks, lights, therm, etc) it will work with? Does the cell card require a separate subscription or does it always work (once installed)? Does it come with the electric cable or is that a separate item to purchase? Thanks :)
