Emergency Alarms and Calls are separate functions that can be individually enabled or 
disabled on each SmartNet/SmartZone and P25 Trunked system. The Emergency option 
button (or menu parameter) is required for these functions. 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

Announcement group of the selected channel

Up to 255 Emergency Lists may be programmed. A specific list may be selected for each 
channel.

An emergency alarm is a special transmission that alerts a dispatcher of an emergency 
situation. It is sent automatically by simply 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. If not, Emergency Alarms are disabled. The 
alarm is sent on the control channel.
