Closing your Red Alert or Incapacitation Alarm
Once you feel that your situation no longer needs monitoring, you can close an alert down.
If your Red Alert activation was raised by the Rip Alarm, you must first re-insert the lanyard plug.
The Red Alert & Incapacitation Alarm call can only be closed by you. After you feel a set of 2 vibrations
or 3 vibrations, press and hold the Red Alert button for 1.5 seconds, you will feel 2 longer vibrations.
The Red Alert is now closed.

management platform, typically on 15-minute intervals. When an Alert is activated, the interval
between device status updates reduces, typically to 30 seconds. This allows the ARC operators to
confirm a device user’s location with relative accuracy should they need assistance. These functions
are described below.
