The NX keypad LEDs provide a quick indication of what stage the panel has reached during setup.

During boot up, the keypad will cycle through red, green, blue and white. Once the panel is ready for initialisation through the Commtel CONFIG app, the keypad LEDs will pulse orange to indicate Installer Mode.

A useful reference when commissioning a system or confirming what needs to happen next.

The NX install guide includes a full LED status reference, including keypad, PCB and I/O board LED indicators: https://www.commtel.io/support/resource-hub/

A signal test is often quicker than moving equipment after it's been installed.

Checking signal strength, available bandwidth and potential antenna locations before installation can help identify issues early and reduce guesswork during commissioning.

The more information available before equipment is mounted, the easier it becomes to make informed decisions about positioning and connectivity.

A system isn't behaving as expected.

Before changing settings or making another trip to site, a few checks can often narrow down the most likely cause.

Signal strength, LED status and system activity can provide useful clues before fault finding begins.

We’ve joined the Association of Fencing Industries (AFI).

The AFI works to improve safety, standards and training across the fencing industry, while helping members stay up to date with regulation changes.

For us, this is about staying closer to the environments our systems are installed into every day. From perimeter security and automated gates through to the wider demands around access control, that understanding helps us continue developing solutions that reduce unnecessary complications and support smoother installs.

Enjoy the long weekend, and we’ll see you soon.
