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
