Honeywell has discontinued the GSMX and replaced it with the more advanced GSMX4G cellular alarm communicator. While the GSMX4G is a 4G cellular alarm communicator that works on AT&T’s newest 4G cellular network, the original GSMX was a 2G cellular alarm communicator. AT&T has announced that by the end of 2016, all 2G communicators will become obsolete as AT&T will no longer support the 2G cellular network. Everyone that has an existing GSMX should consider replacing it with a GSMX4G as soon as possible as certain areas of the country have already experienced a drop in cellular service using the 2G network.

The Honeywell GSMX is an AlarmNet cellular alarm monitoring communicator that installs easily right onto your Honeywell home security system’s alarm control panel. Home security systems have historically used traditional phone lines to transmit alarm signals to a central station for alarm monitoring. However, more and more homes and businesses are getting rid of their traditional phone lines and switching to voice over internet protocol (VoIP) phone services or simply using cellular phones as their means of communication. This transition away from traditional phone lines presented a problem for the alarm industry. Honeywell’s AlarmNet division has provided the answer to this problem. AlarmNet alarm communicators provide your security system with an alternative communication path. The GSMX cellular communicator sends the alarm signals from your Honeywell security system to AlarmNet’s Network Control Center over the wireless cellular network. The Network Control Center then automatically and immediately forwards the alarm signals on to Alarm Grid’s central station. AlarmNet provides reliable protection and ensures that all your alarm signals get through to the central station no matter what.

The GSMX cellular alarm communicator is different than the Honeywell GSMV in that it is powered by your home security system. Instead of needing to plug in an AC transformer, the auxiliary power terminals of your security system will provide the 200mA of power needed by the GSMX. Before purchasing the GSMX, you should ensure that your home security system has enough available power for the cellular alarm communicator. If you do not have enough power, you should purchase the GSMV instead or install an auxiliary power supply to power the GSMX.

The Honeywell GSMX is also unique in that it’s plastic enclosure has a threaded bottom that fits right into a knockout on the top of your Honeywell VISTA Series security system’s metal alarm cabinet. You will save time on the installation of the GSMX as you won’t need to mount it in a remote location or worry about mounting it on a wall. The GSMX does not have its own battery backup as it will get power from your security system’s existing battery backup.

As an AlarmNet alternative alarm communicator, the GSMX is compatible with the Total Connect interactive service. Total Connect access allows you to arm or disarm your security system from any web browser or iPhone®, iPad®, Blackberry® or Android™ device. The interactive service also allows you to setup instant notifications based on different system events. You can get a text message or an email every time your GSMX enhanced security system is armed or disarmed to keep an eye on who is using your security system and when. The Total Connect service is a great way to stay connected to your home security system from anywhere.

The Honeywell GSMX is a 2G cellular communicator that connects with the AT&T 2G Network, which has since been shut down. As a result, this communicator has been discontinued for sale, and it can no longer be activated. Existing modules will no longer function. When the AT&T 2G Network was still active, the Honeywell GSMX Cellular Communicator provided reliable monitoring service for a connected VISTA System by connecting it with the AlarmNet Servers. This allowed the system to be used with the Total Connect interactive monitoring platform. This communicator was good for its time, but now it is seen as a relic of the past. It also drew all its power from the panel, which often led to power supply issues for the system. We give this communicator a 3 Star rating.

The main thing to like about the Honeywell GSMX when it was still usable is that it provided reliable monitoring service. Cellular connectivity is known for being very reliable once an adequate signal is obtained. This isn't always the case for IP connectivity, as an internet outage will take a system offline. Many Honeywell VISTA users relied on the Honeywell GSMX to provide them with reliable and trustworthy monitoring for their homes and businesses. Once activated, the module also allowed the system to connect with the Total Connect servers, provided the feature was included in the user's alarm monitoring plan. We also like the fact that this communicator can be mounted on the outside of the panel's metal enclosure. This made it easier to install.

The downsides to the Honeywell GSMX are pretty glaring. It can no longer be activated or used in any manner. Anyone with this communicator should have upgraded a long time ago. If you need a new communicator at the time of this writing (late 2019), then we strongly recommend getting an LTE communicator. Another downside to this communicator is that it draws all of its power from the panel rather than using a plug-in transformer. As a result, you will need to calculate its maximum power draw (250 mA) into any draw calculations. That's quite a bit of power for panels that only supply power of up to 600 mA (low P-Series) or 750 mA (TURBO Panels) without the use of a power supply.

The Honeywell GSMX was a good communicator for its time. But it is completely obsolete now. We give it 3 Stars.

Good: Reliable Connectivity, Total Connect, Mounts to Metal Enclosure

Bad: Can No Longer Be Used or Activated, Discontinued, Draws Power from Panel

Bottom Line: 3 Stars
