Why Am I Getting Supervision Trouble On My 2GIG SMKT8e-345?

You are getting supervision trouble on your 2GIG SMKT8e-345 because the zone was not properly cleared out when replacing an old sensor or switching the zone to a different Smart Area Partition. Another possibility is that the zone was set up with the wrong equipment code for the SMKT8e-345.

The 2GIG SMKT8e-345 is an encrypted smoke/heat and freeze detector for the 2GIG GC3e and 2GIG GC2e. Like most wireless sensors, the 2GIG SMKT8e-345 follows similar rules for supervision trouble. This condition normally indicates that a security system has not received a check-in signal from an enrolled wireless sensor within a certain period of time. This is usually the result of the sensor not being powered on, and therefore being unable to send a check-in signal. It could also mean that the sensor is either located too far away from the alarm panel or is somehow being blocked from sending its wireless check-in signal to the intended destination. The purpose of this trouble condition is to let the user know that the alarm system is not receiving communication from an enrolled wireless sensor and to take action so that the issue is resolved. Once you have fixed the problem, you can then take the necessary steps to clear the trouble from the system. GC3e users can follow this process.

But with 2GIG Security Systems, there are some known issues that can result in supervision trouble conditions for issues outside of those mentioned above. There are some important things to keep in mind to prevent these issues from occurring. First, if you ever need to replace a sensor with a new one, then you must delete or clear the zone completely, and reprogram it from scratch. This is true even if you are replacing the old sensor with a new one of the same model. If you try to save time by just changing the programmed Serial Number to reflect that of the new sensor, while leaving the other zone settings untouched, then the zone may display the trouble condition. For more information on how to properly replace a sensor on a 2GIG GC3e, please see this relevant FAQ. If you are working with a 2GIG GC2e System, then the same general principles apply, but the process for clearing a zone and then reprogramming it from scratch will differ for that panel. GC2e users can review this FAQ for information on how to program zones.

Likewise, you also need to delete a zone and reprogram it entirely if you are switching the sensor to a different partition on the system. This is only applicable to the 2GIG GC3e, as the 2GIG GC2e is a single-partition system that does not allow you to make Partition Assignments. But on a GC3e, if you try to cut corners by just changing the Partition Assignment for an already-programmed zone, then you may experience supervision trouble. To prevent this from happening, make sure to clear the zone entirely, and then reprogram it from the beginning. For a detailed look at making partition changes on a 2GIG GC3e Zone, please see this comprehensive FAQ.

Lastly, you must make sure that the 2GIG SMKT8e-345 is set up with the correct Equipment Code. Using a different Equipment Code has been known to cause supervision trouble. For the 2GIG SMKT8e-345, the correct Equipment Code to use is 2058.
