7.2 Protected Premises Control Unit Overview

7.2.1 Architecture for Protected Premises Control Unit
In Protected Premises Control Unit mode, there must be one workstation and one NFN gateway. The NFN gateway
must be installed on the same PC that is running the workstation software application. See
of Protected Premises Control Unit system architecture.
• Running this workstation in Protected Premises Control Unit mode ULC requires it to be operated by trained
personnel.
• If multiple gateways are present or required, the workstation software application must run as a Proprietary
Receiving Unit.
• Protected Premises Control Unit mode is to be used on a dedicated fire protective signaling network only.

7.2.2 Event Handling Overview for Proprietary Premises Control Unit
The following features are provided by the workstation as a Proprietary Premises Control Unit:
• Block acknowledge of troubles, supervisory, and security events
• Always requires an individual acknowledgment of alarms
• Display and Command Center (DCC)
7.3 Proprietary Receiving Unit Overview
7.3.1 Architecture For Proprietary Receiving Unit
Proprietary Receiving Unit fire alarm systems monitor the life safety systems of the protected premises that are under
the same ownership. The proprietary receiving unit can be located at the protected premises or at multiple protected
properties. Properties may consist of a single building, such as a high-rise building, or several buildings, such as a
campus where multiple separate buildings report to a proprietary receiving unit owned and operated by the campus.
The property may be contiguous or non-contiguous. If it is non-contiguous, it may consist of protected properties at
remote locations. Codes do not limit the geographic distance that may exist between non-contiguous properties. This
permits an owner to oversee protection features at geographically diverse locations from a single proprietary
receiving unit.
The Intelligent Fire Integrator system is a proprietary receiving unit fire alarm system that may serve contiguous and
non-contiguous properties, either of which is under one ownership. Monitoring is typically performed from a
proprietary receiving unit located at the protected property, or at one of multiple non-contiguous protected properties,
at which trained, competent personnel are in constant attendance. Monitoring may include, but is not limited to, the
proprietary receiving unit; power supplies, signal-initiating points, initiating point circuits, signal notification
