6.3.7 Operator Responses To SAM Alarms
The system includes a buzzer to provide beeps to get the operators attention. The system also
comes standard with speakers to alert the operator and others on the fireground when critical
events are happening with the water flow or truck. SAM Speaks follows selected caution/mes-
sages/warning tones by spoken details of what is happening so the operator can react.
Table 8 show symptoms, potential causes, and remedies of potential issues with the system. If
your issue is not on this list, see the SAM Technical Manual (FSG-MNL-00211) or contact Hale
Customer Support (800–533–3569).
