Alert
Alert tone sequences can be generated for three events:
normal call, autocall
and
emergency
tone sequence receptions.
Each of these events has assigned unique alert tones.
Call
is a 1khz tone with a 240ms on and off period.
Autocall
is a
400hz tone with a 240ms on and off time.
Emergency
is an alternating 1khz and 400hz tones at 120ms on and 30ms off
times. Each of the three events can generate a certain number of beeps or continue until the cancel alert button is
pressed, the PTT input becomes active or any button is pressed. The tone being generated relates to the last sequence ID
received, if another call is received before the previous alert is canceled, the old alert tone will be replaced with the new.
If the FIFO buffer is full or the call is suppressed, no tone will be generated.
In addition to generating an alert tone, the
alert relay
can be activated with reception of an event. The relay can be
activated with the alert tone or until the cancel alert button, PTT in is activated or any button is pressed. When set to
‘
on till acknowledged’
, the relay is not toggled with alert beeps but becomes active when the call is received and
deactivated when PTT in or cancel alert or any other button is pressed.
When alert tones are actually being generated, the alert LED is on and the
speaker enable
output is active.
Programming parameters, alert:
Alert, call, enable:
Enables alert tone generation when a call sequence is received.
Alert, call, duration:
Indicates the duration of the alert tone.
Alert, call, relay action:
Enables the activation of the alert relay with the reception of a call sequence. The relay can be
turned off when the beeps time out, when the cancel alert button is pressed or when the PTT input becomes active.
Turning
alert, call, enable
‘off’ and
alert, call, relay action
to ‘on with beeps’ is invalid since no beeps would be
generated. In this case the relay would never be activated.
Alert, autocall, enable:
Enables alert tone generation when an Autocall sequence is received.
Alert, autocall, duration:
Indicates the duration of the alert tone.
Alert, autocall, relay action:
Enables the activation of the alert relay with the reception of an autocall sequence. See
alert, call, relay action
.
Alert, emergency, enable:
Enables alert tone generation when an emergency sequence is received.
Alert, emergency, duration:
Indicates the duration of the alert tone.
Alert, emergency, relay action:
Enables the activation of the alert relay with the reception of an emergency sequence.
