Card LEDs illuminate after a button press to confirm the action was received by the network. The color that flashes corresponds to the emergency category that action is mapped to. Because categories and their display colors are configured per organization, the specific colors your Cards show will depend on your setup.
To see which colors are assigned to which categories for your organization, go to Settings > Configure > Notify Categories (or Categories if your organization does not use STOPit Notify).
The one universal LED behavior
Across all deployments, regardless of configuration: 5 rapid Blue blinks means the device has powered on successfully after a battery swap. This is a device-level signal, not a category color.
LED only flashes on successful receipt
The Card's LED only illuminates if the signal was successfully received by the Repeater network. If you press the button and see no LED response, the Card may be out of range, the battery may be low, or the nearest Repeater may be offline. See Troubleshooting Your Rescue Cards for more detail.
No other LED states
The Card does not have a steady-on LED, a low-battery indicator light, or a connectivity status light. All device health information — battery level, online/offline status, last heartbeat — is visible in the dashboard at app.punchrescue.com under Devices.
