The GBH panel is used in medical oxygen backups in clinics and hospitals.

When any of the backup levels fall below the threshold set by the technicians, the panel indicates which backup is at a low level with a light. In addition to providing visual alarms, it also generates an audible alarm to ensure that hospital or clinic staff are immediately aware of the situation. The audible alarm can be silenced for a predetermined period and will sound again once the time has elapsed if the alarm is still active.
