Operative statuses of the Previdia Max system
Standby: Operating status of the control panel when there is no ongoing alarm or fault signalling.
This status is altered by the occurrence of an event, that is, an operative status which is characterized by an activation
(when the event occurs) and a reset (when the event ends).
Alarm: Status of the control panel generated by manual activation (for instance, from a call point) or automatic
activation (signal from a detector). This is followed by an alarm signal.
Early warning: This is the status of the control panel during the interval (delay) which runs between the detection of an
alarm condition and the actual signalling of the alarm (delay).
Investigate: This command is activated by a supervisor, during an early-warning condition, it provides an extension of
the early-warning delay and allows the supervisor to verify the cause of the alarm.
Evacuate: This command is activated by a supervisor, during an early-warning condition, it cancels the delay and
instantly activates alarm signalling (evacuation).
Reset: This operator-activated command annuls the current status of the control panel (and the relative signalling and
activations) and resets the system to standby.
This command can be disabled in order to prevent users from activating it by mistake and annulling active signals.
Disable: This command disables part of the system
Emergency: This is the operating status of the control panel when a fault is detected on the main CPU on the FPMCPU
module, as a result the emergency CPU will be activated automatically.
The emergency backup CPU ensures the efficiency of the basic functions of the system (alarm signal reception from
points and activation of outputs). However, it does not ensure all the configured activation logic. For total redundancy of
all the configured functions, it is necessary to add and configure a second FPMCPU unit to the control panel.
