How to Add, Remove Z-Wave Devices on an Interlogix NX Panel

The Z-Wave controller on the Interlogix NX is built into the Alarm.com cellular module, so swapping the panel requires no action in regards to Z-Wave, while swapping the module requires the deletion and addition of any existing Z-Wave devices.

It is recommended to enroll no more than 60 total Z-Wave devices and up to 5 thermostats to ensure network stability. Z-Wave network stability depends on many factors, including the number of enrolled devices, network layout, environmental interference, and the number and types of rules and schedules being used.

The more Z-Wave devices that are in a network, the longer basic functions (e.g., network rediscoveries, etc.) may take to complete.

To enroll Z-Wave devices using the panel:

Important: If using a module on a firmware version lower than 187a, the Z-Wave LED is L2 instead of L5 for the following instructions.

  1. Locate the Alarm.com module.
  2. Press and hold the red button on the module, and watch the L5 LED.
  3. Release the button once the L5 LED flashes in a 4-flash pattern to indicate it is in add mode.
  4. Trigger a device to add it to the network. (trigger for inclusion/exclusion varies by device)
  5. When a device is added successfully, the L5 LED remains solid for 60 seconds and the panel beeps.
  6. It is required to re-enter Add Mode before triggering the next device, which cannot be done until the L5 LED turns off.
  7. Devices should show up on the Alarm.com Website and app, within five minutes of adding the devices

  3. Release the button once the L5 LED flashes in a 4-flash pattern. This indicates add mode.
  4. Press and hold the red button on the module a second time, once again watching the L5 LED .
  5. Release the button once the L5 LED flashes in a 2-flash pattern to indicate it is in delete mode.
  6. Trigger a device to erase its network data and delete it from the network.
  7. When a device is deleted successfully, the L5 LED remains solid for 60 seconds and the panel beeps.
  8. It is required to re-enter Delete Mode before triggering the next device, which cannot be done until the L5 LED turns off.

Perform a Network Rediscovery

After adding all desired Z-Wave devices to the network, it is important to run a Network Rediscovery. Running a Network Rediscovery allows each device to detect nearby devices and identify the best path of communication to the panel, as well as alternate paths in the case of a node failure.

With the NX panel, a Network Rediscovery can only be run from the backend, this cannot be done locally. If you are currently using service through Surety, let us know and we can send the command for you.
