Reading LCD messages
The 2-CMDN(-C), the 2-SMDN(-C), and the 2-LSRA(-C)
feature a liquid crystal display (LCD). The LCD turns off after 4
minutes of inactivity to save power. Any change of state, off-
normal condition, or front panel switch activation will turn on
the LCD's back-lighting. The system's main controller module
automatically updates time and date information. The LCD does
not display point address information unless the system
programmer includes it as part of the message.
Figure 3-4 illustrates an LCD with no messages pending. The
fire alarm system has no problems at the moment of the display.
In Figure 3-5, however, the LCD indicates a trouble condition
for a Signature series device in the Janitor’s closet.
