Alarm functions
4.1
User alarms
Alarms that fall into this category are alarms initiated by the user. This can be done
by pressing the
Alarm button (B1)
on the NOVO or using a portable trigger, SMILE.
An alarm triggered by an accessory such as WALL, PIR II or SMOKE can also belong to
this category.
An alarm received by NOVO will be handled in accordance with the configuration for
the alarm type received
4.1.1 Passive alarm
The Passive alarm can be triggered to indicate that an event has not occurred for a
certain time. The purpose of this function is to raise an alarm if the user has not been
active for a given period of time.
Assuming the unit is configured correctly this functionality is started by:
• the first radio message from a transmitter registered as a passive alarm, e.g. PIR II
or INKA.
• A push on the
Reset button (B2)
.
NOVO will consider received User alarms (see
"4.1 User alarms") as user activity and
will therefore restart the countdown until a Passive alarm is triggered.
Example: An infrared detector can be registered in the NOVO as a passive alarm.
When the infrared detector detects movement it sends an alarm message to NOVO. If
NOVO does not receive this message from the infrared detector or any user alarm for
8 hours, NOVO will trigger the Passive alarm.
If the
Reset button (B2)
is configured to reset Passive alarm, the unit will generate a
warning signal 60 seconds before triggering the Passive alarm. To stop the warning
and cancel the Passive alarm, press any button or any registered transmitter. If the
Passive alarm is not cancelled it will be triggered and handled as configured.
4.1.2 Home/Away
The purpose of Home/Away function is to communicate to the alarm central if the
user is leaving the premises. Setting the unit to Away mode will also pause Passive
functionality and Radio transmitter surveillance. When unit toggles between Home
and Away it can be configured to transmit Home alarm and Away alarm respectively.
Away mode
In Away mode the follwing is valid:
• Passive functionality is paused
• Radio supervision for portable transmitters (e.g. SMILE) is paused
• Away mode is indicated by L6, see "3.1.4 Extra button LED (L6) indications".
Exiting Away mode can be done as follows:
• NOVO receives a
User alarm from trigger
or
User alarm from button
. NOVO will exit
Away mode, handle the user alarm as configured and then trigger a Home alarm.
•
Extra button (B3)
is configured to send either Home alarm or Away alarm.
• NOVO receives a radio message with the alarm type Home or Away from a
transmitter.
