The alarm call
5.1
Alarm event
Any event in the NOVO that will result in the transmission of an alarm is an
alarm
event
.
• Alarm events can be user initiated, e.g. pressing the
Alarm button (B1)
.
• Alarm events can be initiated by unit as a result of any kind of surveillance of the
status of the unit, e.g. detection of mains failure.
• Alarm events can be initiated by the unit as a result of any kind of surveillance of
registered transmitters, e.g. Radio out of range.
• Alarm events can be received from registered transmitter, e.g. Smoke alarm.
For an alarm event to result in an alarm call the configuration of the following
parameters must be valid.
5.1.1 Alarm type
An alarm event is associated with a certain
alarm type
. Either the alarm type is
received directly from a transmitter, determined by the nature of the event (e.g. radio
interference) or it is determined in the configuration of NOVO (e.g. handling of alarm
type 0x00 from a transmitter). The alarm type typically describes the reason for the
alarm. Each alarm type has a number of configurable parameters dictating among
other things if the alarm type is to be reported to an alarm receiver and/or CMP,
speech direction settings, priority, audible settings, pre-call settings etc..
5.1.2 Alarm type group
All alarm types belong to an
alarm type group
. The specific group can be configured
for each alarm type. 16 different alarm type groups can be defined. Each alarm type
can only belong to one alarm type group.
5.1.3 Sequence
The alarm type group determines what
sequence
will be used when handling the
alarm. Each sequence has a number of configurable parameters that determine how
to transmit the alarm. 8 different sequences can be defined.
Each sequence has 10 possible steps. Each step has a configurable
Carrier
(e.g.
PSTN) to be used,
number of call attempts
for each step and
next step
if alarm
transmission is successful.
5.1.4 Call type
Each step also has a
call type
which contains among other things details of how to
establish the call and what
protocol
to use, if
callback
is to be active and
heartbeat
configurations.
