Emergency Alarm
Emergency Alarm
is the function to send an Emergency Alarm Request message before the transceiver enters Emergency
Mode to notify the base station that the transceiver is in an emergency situation.
Using this function can reliably notify the base station that the transceiver is in an emergency situation.
When the
Emergency
key is pressed or Lone Worker and various Activity Detection functions are activated, an Emergency
Alarm Request message is sent to the base station if the transceiver is in a P25 Conventional system, or to the system if
the transceiver is in a P25 Trunking system. When the transceiver receives an ACK from the base station or the system,
“Ack Received” appears on the display and the transceiver enters Emergency Mode.
If the transceiver cannot receive the ACK after sending the Emergency Alarm Request message, the transceiver resends
the Emergency Alarm Request message. If the transceiver still cannot receive the ACK after sending the Emergency Alarm
Request message 5 times, the transceiver enters Emergency Mode.
Note
If a zone or channel is changed while the transceiver is in Emergency Mode, the transceiver sends the Emergency Alarm
Request message on the new channel.
