Protected Premises Control Unit vs. Proprietary Receiving Unit Event Handling
7.3.2 Overview of Event Handling for Proprietary Receiving Unit
The Intelligent Fire Integrator Workstation, as a Proprietary Receiving Unit, complies with NFPA-72 and UL 864.
The following features are provided by the workstation software application as Proprietary Receiving Unit:
• Each change of state is individually acknowledged.
• The maximum duration between the initiation of an alarm signal at the protected premises, transmission of the
signal, and subsequent display and recording of the alarm signal at the workstation does not exceed 90
seconds.
• Display rate of subsequent alarms at the workstation is equal to or faster than one complete signal every 10
seconds.
• Trouble signals and their restoration to normal are indicated within 200 seconds.
7.4 Protected Premises Control Unit vs. Proprietary
Receiving Unit Event Handling
Events are displayed the same way whether the workstation is running as a Protected Premises Control Unit or
Proprietary Receiving Unit. For example:
• If the event is acknowledged at the panel, "Acked" will be displayed prefixing the event in the New Events
list.
• If the workstation has node control of the point, a colored box displays to the left of the event in the
Navigation Tree.
• If the event is unreliable (meaning it was reported while a gateway or node was in fault), an asterisk (*) is
displayed prefixing the event in the New Events list.
However the workstation handles return-to-normal conditions and acknowledgments in a significantly different way,
depending on operating mode as described in
Table 7.1 Protected Premises Control Unit vs. Proprietary Receiving Unit Comparison
If an event is acknowledged at the Fire Alarm Control Panel (FACP),
it is acknowledged at the workstation.
If an event is acknowledged at the workstation, it is acknowledged at
the Fire Alarm Control Panel (FACP).
When an event returns to a normal state, it is removed from the New
Event listing.
When an event returns to a normal state, it is acknowledged at the
FACP.
