SMARTNET / SmartZone / P25 Trunked Features
2
When the emergency alarm is acknowledged, “ACK RCVD” is briefly displayed and
the emergency acknowledge tone (five beeps) sounds. Silent operation may also be
programmed in which case no tone sounds and there is no indication that an
acknowledgment occurred.
3
The radio continues to transmit this message until an acknowledgment is received or
the programmed number of attempts have been made. The emergency alarm mode is
exited when radio power is cycled, or by pressing and holding the Emergency option
switch.
7.9.2
Emergency Call Alert
This feature notifies a user when an emergency call is being made on their selected P25
Conventional or P25 Trunking Talkgroup. The radio should also be programmed with an
“Emergency Clear” button.
If an emergency call is received by the radio on the selected channel, the emergency alarm
ACK tone will sound (five consecutive tones), and the Emergency Received message will
display, followed by the unit ID of the emergency radio. If any other emergency calls are
made after this initial one using a different radio, the tone will not sound, but the unit ID
will be updated to reflect the most recent emergency call. To exit out of this state, press
and hold the “Emergency Clear” button. The radio should return to its normal display, and
the Emergency Received message should no longer show.
7.9.3
Emergency Calls
An emergency call urgently requests access to a voice channel (an emergency tone usually
does not sound at the console unless the call is combined with an Emergency Alarm). An
emergency call is placed by pressing the Emergency option button. If the Emergency Hot
Mic feature is enabled, the emergency call is automatically transmitted without having to
press the PTT switch (see following description). The system to which the emergency
channel is linked must have Emergency Calls enabled.
