SMARTNET / SmartZone / P25 Trunked Features
6.9
Emergency Alarm and Call
Emergency Alarms and Calls are separate functions that can be individually enabled or
disabled on each SMARTNET/SmartZone and P25 Trunking system. The Emergency
option switch, soft button (Lightning Control Head only), or menu selection is used for
these functions.
The user can set an external line by pressing the emergency button. External devices can
trigger off of the radio’s external line. If the “Ext Emergency” Option is enabled by
programming and the user presses the emergency button, the Aux B line on the accessory
connect shall be set to low (0V). It remains low until the External Emergency Time has
passed or the user exits the emergency. If the user presses emergency during the External
Emergency Time, the timer starts over. If the user exits emergency before the External
Emergency Time has passed, the output line returns to Vbatt.
Other emergency features are as follows:
• Emergency Alarms are transmitted on the selected talkgroup if emergency calls are
disabled, and on the emergency talkgroup if emergency calls are enabled.
• Emergency Call talkgroup selection priority is as follows. For example, if a global
emergency channel is not programmed, the emergency talkgroup of the selected channel
is used and so on.
- Global (radio wide) emergency channel
- Emergency group of the selected channel
- Talkgroup of the selected channel (tactical)
- Announcement group of the selected channel
• The emergency programming of the system to which that emergency talkgroup is linked
controls the emergency operation.

Alarms are disabled. The alarm is sent on the control channel.
Proceed as follows to send an emergency alarm:

Press the Emergency option switch. The radio automatically transmits the emergency
alarm if programmed.
