4.14 Fire Ground Mode
Fire Ground Mode allows any radio optioned for Fire Ground Commander Mode to
operate in Fire Commander Mode, and any subscriber optioned for Fire Ground First
Responder mode to run in Fire Responder Mode. A radio can be programmed for both
modes; however, the radio can only operate in one of the modes at a time. The user must
exit the current mode to enter the opposite mode. Fire Ground First Responder is available
on P25 Trunking and SmartNet/SmartZone channels. The Fire Commander Mode is
limited to the Conventional System. If the Fire Ground Channel is not a Conventional
channel and the user tries to enter Commander Mode on that channel, the radio will bad
beep. The only Fire Mode feature currently offered on the P25Trunking and Smartnet/
Smartzone protrocols is the Lock Keypad/Volume option.

The intended set up is to have one radio running in Fire Commander Mode, and remain
outside the emergency site. The remaining radios operating at, and inside, the emergency
site should operate in Fire Responder Mode. The Fire Commander can issue Evacuation
Alerts to notify the First Responders they must evacuate. The Fire First Responders can
perform a Communication Check to determine their signal strength to ensure they are in
range of the Fire Commander.

Each radio can be programmed for up to four Fire Commander buttons (Fire Commander
1 through Fire Commander 4), and up to four Fire First Responder buttons (Fire
Responder 1 through Fire Responder 4). Each Fire Mode can be selectively programmed
for specific Fire Commander and Fire Responder options. Each Fire Mode can also be
programmed to operate on a designated channel or the current selected channel. If a
designated channel is chosen, the radio will automatically switch to the designated
channel when that Fire Mode is entered.

There are times when P25 digital voice is better than analog voice. Under these
circumstances it is best to operate in the P25 digital voice mode. If programmed, the radio
will change its transmit mode, based on signal strength, from analog to P25 Digital. If the
radio receives carrier with a RSSI below the Fair RSSI threshold, the radio will
automatically switch its transmit type from analog to P25 Digital. This will be evident as
the received audio should sound suddenly clear without background static as heard on an
analog channel.
