9.28 EMERGENCY COMMUNICATIONS
The P7300 portable radio is capable of sending an emergency alert and making emergency calls on the
network. The OpenSky system handles emergency calls with the highest priority, allowing you or the
people you serve to get needed help.
Emergency call and alert capability for a profile is configured by the system administrator.
The radio that initiates an emergency alert emits a signal of 3 distinct beeps that only goes to
the dispatch console.
Table 9-11: Emergency Calls vs. Emergency Alerts
EMERGENCY ALERT EMERGENCY CALL
An Emergency Alert message is sent
to the dispatcher console. The
dispatch console plays an emergency
tone when it receives the message.
An Emergency Alert message is sent to the dispatcher console. All peers
(radios and consoles) and the dispatch console play the emergency tone
whenever an emergency call is detected. An emergency tone plays for each
new emergency, or when a profile is changed, (assuming there is an emergency
on one of the Talk Groups for the new profile).
If the orange LED is flashing rapidly, the radio is receiving an emergency call. If
the LED is flashing every ½ second, the selected Talk Group is in the emergency
state (although not transmitting). If the selected Talk Group is in the emergency
state, an asterisk displays next to the Talk Group name.
No emergency audio (voice)
transmission (hot-mic) capability
available (per programming by system
administrator)
In
addition to the Emergency Alert signal, the microphone goes hot for a
predetermined length of time to allow for emergency audio (voice) transmission.
The radio declaring the emergency has channel access priority. Note that the
User can also use the PTT after the pre-determined hot-mic audio transmission,
or during to extend the initial hot-mic audio transmission. However, if the PTT is
pressed and released during the hot-mic period, the hot-mic transmission
will end as soon as the PTT is released.
