How Do I Clear a Check 950 Comm Trouble On a Honeywell Lyric Controller?

You can clear a Check 950 Comm Trouble on a Honeywell Lyric Controller by making sure the system's communicator is registered and properly communicating with the AlarmNet servers and then arming and disarming the system. The Check 950 Comm Trouble should then clear from the screen.

The Honeywell Lyric shows a Check 950 Comm Trouble when the panel cannot connect with AlarmNet through its set communication path. This could be because the communicator is not registered, or because the set communication path is not working properly. If you are using IP connectivity, then this could be because there is an internet outage. If you are using cellular, then there could be a problem with the cellular tower, or your system's cellular signal might be weak. You might want to have your monitoring company check the cellular signal strength to make sure it is strong enough. Weak cellular signal can usually be addressed by adding a cellular amplifier or a cellular antenna.

When a Lyric system is registered with AlarmNet, it tries to maintain a constant connection with the servers. The Lyric will report a Check 950 Comm Trouble if the system's WIFI and/or cellular connection goes down for a set period of time. This set period of time is determined by the WIFI Fault Time for WIFI, and by the Cell Fault Time for cellular. The default settings are 00 and 60 minutes respectively. Both the WIFI Fault Time and the Cellular Fault Time settings are found within the Communicator Menu of Programming. This menu can be viewed by choosing Security > Tools > enter Installer Code (default 4112) > Program > Communicator.

Once you enter the Communicator Menu, you can press the down arrow on the right side of the screen to access the WIFI Fault Time setting. Pressing the down arrow a second time will allow you to access the Cellular Fault Time setting. Please note that these settings can only be changed by your alarm monitoring company, and you will not be able to adjust them at the Lyric Panel. Also note that these settings will only be displayed if their respective communication paths are enabled. For example, if you have cellular communication disabled for the system, then you will not be able see the Cellular Fault Time setting. You can set the system's communication path using the toggle option in the upper-left corner of the Communicator Menu. This is the screen you see when you first press "Communicator" from the "System Programming" page. The available selections include WIFI, Cellular, WIFI & Cellular, and None. Do not leave a communication path that you are not using enabled.

If your Lyric System shows a Check 950 Comm Trouble, complete the following steps to clear the trouble:

1. Silence the Trouble. If you haven't already, press the Home key to silence the trouble sound. This will let the Lyric panel know that you are aware of the existing trouble condition.

2. Fix any communication issues. Make sure that your system can communicate with the AlarmNet servers using the communication path(s) you have set. If you have a communication path enabled that you do not plan to use, disable that path. Remember that you can toggle different selections using the Communication Path field, which is in the upper-left corner of the Communicator Menu.

If you are using WIFI, you might consider asking your monitoring company to increase the WIFI Fault Time setting for your system. This will prevent a Check 950 Comm Trouble condition from appearing due to a relatively short internet outage. However, be advised that by default, the WIFI Fault Time setting is set to 00. A setting of 00 causes the WIFI communication path to be unsupervised.

If you are using cellular, then you should also make sure that your system is receiving an adequate cellular signal. You can ask your alarm monitoring company to check this. If your monitoring company finds that your panel has a weak cellular signal, then you might consider adding a cellular amplifier or a cellular antenna. You might also want to check and see if there have been any cellular service outages in your area.

Additionally, remember that any enabled communication path must be registered with AlarmNet by your alarm monitoring company. This requires signing up for a compatible alarm monitoring plan. You should contact your monitoring company and make sure that the communicator for your Lyric System is registered with AlarmNet. If you are an Alarm Grid customer and you need us to check your cellular signals, or if you need us to register your communicator, then the best way to reach us is to email support@alarmgrid.com.

You can also get a basic check of cellular signal by going to Security > Tools > Installer Code (default 4112) > Program > Comm Diagnostics > Cellular Information. This will show you the type of communicator installed, and a Signal Strength reading in bars. To exit programming, press the return arrow in the upper-right side of the screen, once-per-screen, until you reach the Home screen.

Once your panel is successfully communicating with AlarmNet across any enabled communication path, follow the remaining steps below to clear the 950 Comm Trouble error:

3. Arm and disarm. Trouble conditions like the Check 950 Comm Trouble are cleared by fixing the issue and then arming and disarming the system. From the main screen of the Lyric, choose Security, followed by Arm Away or Arm Stay. Then enter a valid code to begin arming. As the system is counting down, choose Disarm. Then enter that same valid code to disarm the system. This will effectively arm and disarm the Lyric.

4. Confirm trouble clear. Now that you have armed and disarmed the system, the Check 950 trouble condition should have cleared. If it hasn't, then that means the system is unable to communicate with AlarmNet through at least one of the set communication paths. Return to Step 1, and make sure the system can communicate with AlarmNet through any communication path that is enabled.
