USING THE SYSTEM
UK
• Operation during manual management of an emergency
Following access, the display will show the status of the zones, indicating – if appropriate - the messages currently activated automatically
via the “Control Inputs”. By default, when first accessed, all the zones have already been selected for a general emergency. Any disabled
zones will not be available (see the DISABLEMENT section). When a current Manual Emergency is in progress, if no General Reset of the
alarms is carried out, any new activations of input contacts will be carried out for the free zones on the basis of how the activated contact has
been programmed (see section 8.6.1 Set> CONTROL INPUTS). Following a GENERAL RESET of the alarms, any re-activation of the input
contacts will have no effect on the zone outputs. When the system is working correctly with the double channels, the display will show:
“ PTT, EVAC or ALERT for general call, ESC muting beep”
In the event of failure of an amplifier, on the other hand, the text on the display will read:
“ Only one channel available FAULT CONDITION”
to show that only one channel is operational.
In any case, manual resetting of the beep signalling a failure is always available, by pressing directly the ESC key. For further information
concerning resetting of the beep see point 8.5.1.1. While an Emergency message is being broadcast, it is possible, if required, to change
the selection of zones, as indicated under 2, to diversify broadcasting of the Emergency message, sending two separate messages to
two different groups of zones (operation with double channel). Any current messages that have already been activated automatically via
an external peripheral unit have a lower priority than the message activated manually, and it is therefore possible to change the message
being broadcast by activating the manual function.
For zones with a current ALERT message activated manually, it is possible to activate the Evacuation message by pressing the EVAC key
directly. For zones with a current EVAC message activated manually, it is only possible to send out an Alert message, which has a lower
priority, after RESETTING the zone, as indicated under point 8.9.4.
• Exiting manual management of an emergency
Upon completion of the procedure for managing the Manual Emergency, press the red EMERGENCY key, which will extinguish, and:
- if no activation from external peripheral units connected to the “Control Input” contacts are activated, the system will return automatically
to the idle condition, displaying the MUSIC menu. The ALARM LED will remain extinguished to indicate that the VOICE ALARM is not
active.
- if there are any current activations from external peripheral units connected to a “Control Input” contact, the system will return to
the Automatic Emergency condition, displaying the INPUT ALARM STATUS menu. Broadcasting of the emergency messages will
resume, on the basis of the programming of the activated inputs and with – if appropriate – the ALARM LED illuminated to indicate an
active VOICE ALARM.
8.9.3 Access to the system for handling a Manual Emergency
• Press the red EMERGENCY key. The display will show the current
status of each zone and a message indicating the procedure for
accessing the Emergency mode or the Operator mode.
• Press the red EMERGENCY key again within about 15 seconds
from the first time (or exit by pressing ESC to return to the Main
page menu).
The EMERGENCY will light up steadily to indicate that a condition
of Manual Emergency has been activated.
Access the external peripheral unit connected
to the CONTROL INPUT contacts. De-activate all the contacts applied to the
CONTROL INPUTS. The system will continue to broadcast any
manually activated messages.
4) End of the Automatic Emergency function, if any, from the input contacts
Exit from Manual Emergency Press the Emergency key once. The system will return to the MUSIC panel.
5) End of the Manual Emergency and return to a Quiescent Condition
