Chapter 4 describes the Application 651 – Operating Mode available in the FHM.
The FHM may be stand-alone or connected to a field panel. The FHM can also send an
alarm notification to a centralized control system. Table 4-1 contains Operating Mode point

Overview
Application 651 is one of two FHM applications. This application is the Operating Mode,
which determines the features that are available to the user.
Occupied/unoccupied mode
Application 651 is capable of using two modes, occupied and unoccupied, set the application
to the appropriate mode using OCC UNOCC (Point 29).
The occupied mode is the most common Operating Mode. In occupied mode, the FHM does
the following:

• Displays face velocity
• Allows the user to initiate an EMERGENCY alarm
The unoccupied mode is controlled from the field panel, AUX DI, or the AUX 2 button as
defined by DI FUNCTION (Point 52) and is typically used when the FHM is not needed for
monitoring alarm conditions.
