Initiating Alarm Broadcasts without Voice
After the desired zone and alarm have been selected, the operator may begin broadcasting the alarm by
pressing and releasing any PTT source such as the main
TRANSMIT button, handset PTT or PTT of a
connected accessory.
Upon pressing PTT, if the selected zone is not active, the unit will generate the necessary DTMF digits to
activate the desired zone. During the DTMF generation, the second line of the display will be:
Z o n e : Z o n e 3
* * * WA I T * * *
After generation of the DTMF sequence, the AMI will begin generation of the selected alarm that will be
broadcast over the unit’s speaker and the selected zone. The display will be as shown below:
A C T I V E : Z o n e 3
A l a r m : L o c k D o w n
“ACTIVE,” “Alarm” and the alarm name will be flashing indicating that the selected zone has been
activated, is within its time-out duration, and the selected alarm is being broadcast. In addition, the
TRANSMIT LED will flash. As long as the alarm is being broadcast the display will remain in this state.
Depending on the programming of the particular alarm selected in the AMI, the alarm may broadcast one
or more times or repeat indefinitely.
If the alarm is programmed to broadcast for a predetermined number of times, upon completion of the last
broadcast, the alarm will cease playback and the flashing of “Alarm,”and the alarm name and the
TRANSMIT LED will cease. After the selected units time out due to inactivity, the display will return to
the alarm edit mode as shown below:
Z o n e : Z o n e 3
