6.10 EMERGENCY ALARM AND CALL
NOTE: The following enhanced conventional emer-
gency features require 5300 firmware 1.21.0/2.0/3.0
and PCConfigure 1.19 or later.
6.10.1 INTRODUCTION
Emergency Alarms and Calls are separate func-
tions that can be individually enabled or disabled on
each SMARTNET/SmartZone and P25 Trunked
system. The Emergency option switch is required for
these functions. Other emergency features are as
follows:
• Emergency Alarms are transmitted on the selected
talk group if emergency calls are disabled, and on
the emergency talk group if emergency calls are
enabled.
• Emergency Call talk group selection priority is as
follows. For example, if a global emergency channel
is not programmed, the emergency talk group of the
selected channel is used and so on.
1. Global (radio wide) emergency channel
2. Emergency group of the selected channel
3. Talk group of the selected channel
4. Announcement group of the selected channel
• The emergency programming of the system to
which that emergency talk group is linked controls
the emergency operation.
6.10.2 EMERGENCY ALARMS
An emergency alarm is a special transmission that
alerts a dispatcher of an emergency situation. It is sent
automatically by simply pressing Emergency option
switch. 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 using Motorola proprietary
signaling.
Proceed as follows to send an emergency alarm:
1. If required, select a channel of a system on which
Emergency Alarms are enabled and then press the
EMER option switch. The radio then automatically
transmits the emergency alarm.
2. Either Normal or Silent operation can be
programmed. With the Normal mode, the red LED
lights, the emergency tone sounds, and
“EMERGNCY” flashes in the display. This indica-
tion continues to flash until the alarm mode is ended
(see step 4). If silent programmed or the Surveil-
lance mode is selected (see Section 4.9), none of
these indications occur.
3. When the emergency alarm is acknowledged, “ACK
RCVD” is briefly displayed and the emergency
acknowledge tone (two beeps) sounds. Silent opera-
tion may also be programmed in which case no tone
sounds and there is no indication that an acknowl-
edgment occurred.
4. The radio continues to transmit this message until an
acknowledgment is received or the programmed
number of attempts have been made. The emer-
gency alarm mode is exited when radio power is
cycled, the channel is changed, or by pressing and
holding* the Emergency option switch.
6.10.3 EMERGENCY CALLS
General
An emergency call urgently requests access to a
voice channel (an emergency tone usually does not
sound at the console). An emergency call is placed by
pressing the PTT switch after pressing the Emergency
option button. If the Emergency Hot Mic feature is
enabled, the emergency call is automatically trans-
mitted without having to press the PTT switch (see
following description). The system to which the emer-
gency channel is linked must have Emergency Calls
enabled.
Emergency Hot Mic
If Emergency Hot Mic has been enabled for
emergency calls, automatic transmitting occurs with
microphone audio unmuted without having to manu-
ally press the PTT switch. The automatic transmit
period is programmed for 10-120 seconds in 10-
second intervals. If this feature or emergency calls are
not enabled by programming, automatic transmitting
* This feature requires firmware 1.24.1/2.2.1/3.2.1 or
later and PCConfigure 1.22.0 or later.
