6.8.1 Emergency Alarms
An emergency alarm is a special transmission that alerts a dispatcher of an emergency
situation. It is sent automatically by pressing the Emergency option button or selecting the
Emergency menu parameter. The system to which the emergency channel is linked must
have Emergency Alarms enabled. The alarm is sent on the control channel.
Proceed as follows to send an emergency alarm:
1 If required, press the Emergency option button or select that menu parameter. The radio
then automatically transmits the emergency alarm.
2 Either Normal or Silent operation can be programmed. With the Normal mode, the red
LED lights, the emergency tone sounds, and “EMERGENCY” flashes in the display.
This indication continues to flash until the alarm mode is ended (see Step 4). If silent
programmed or the Surveillance mode is selected (see Section 4.10), none of these
indications occur. If “No Rx Activity During Emergency” is programmed, receive
audio, the front panel LED, and receive icons are disabled in the receive mode.
3 When the emergency alarm is acknowledged, “Ack Received” 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.
4 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
button.
6.8.2 Emergency Call Alert
This feature notifies a user when an emergency call is being made on their selected P25
Trunking Talkgroup.
