Emergency Alarm and Call
Emergency Alarms and Calls are separate functions that can be individually enabled or
disabled on each analog and P25 conventional system. The Emergency option button or
menu parameter is required for these functions. Emergency Alarms and Calls are
transmitted on the global (radio wide) emergency zone/channel if one is programmed. If it
is not programmed, the emergency is transmitted on the selected channel. The emergency
programming of the system to which that channel is linked controls the emergency
operation. Up to 255 Emergency Lists may be programmed. A specific list may be
selected for each channel.
