Emergency Alarm and Call Section 5 - Conventional Mode Features
5.9.3.1 Emergency Hot Mic
If Emergency Hot Mic has been enabled for emergency calls, automatic transmitting
occurs with microphone audio unmuted without having to manually press the PTT switch.
The automatic transmit period is programmed for 10-120 seconds in 10-second steps. If
this feature or emergency calls are not enabled by programming, automatic transmitting
does not occur. This feature is initiated only on the first press of the Emergency button.
Subsequent presses do not trigger automatic transmissions. To reset this function, cycle
power or press and hold the Emergency button.
5.9.3.2 Placing an Emergency Call
1 If required, select a channel of a system on which Emergency Calls are enabled and
press the Emergency option button or select that menu parameter. The Emergency Call
is then sent as described in Section 5.9.1 if applicable.
2 If the preceding Emergency Hot Mic feature is enabled, the call is automatically
transmitted without pressing the PTT switch. If it is disabled, press the PTT switch and
begin speaking as with a standard call. If the channel is changed, operation continues on
the new channel in the emergency mode.
3 With analog calls, subsequent presses of the PTT switch cause the DTMF emergency
ID to be sent according to the ANI programming (if DTMF ANI is enabled on the
channel). With digital calls, the calls continue to have the emergency bit set.
4 If the Surveillance Mode is enabled (see Section 4.10), all indicators, lights, and tones
are disabled. If “No Receive Activity During Emergency” is programmed, receive
audio, the front panel LED, and receive icons are disabled in the receive mode.
5 To exit this mode, cycle radio power or press and hold the Emergency button.
5.9.4 External Emergency Switch
5100 ES radio models support the External Emergency feature. A special man-down
switch (currently available only from third-party vendors) can be attached to the accessory
connector of the radio.If this feature is enabled by programming and the radio is in a
horizontal position for longer than the programmed time (0-63 seconds), an emergency
condition is triggered the same as if the Emergency button was pressed. The emergency
can be canceled by a press and release of the Emergency button.
Note Accessories, such as speaker-microphones, cannot be used with this feature.
