Installing the PA Ready Option
The PA Ready option provides a PA Ready signal generally used for the purpose of
controlling a PA Ready indicator. This indicator may be in a console, or it may simply be
a light.
The PA Ready option primarily consists of a serial cable with flying leads (IP FSA PA
Ready Cable, P/N 709-7929). The flying leads provide the ready signal to the connected
third-party equipment, such as the “busy input” of a console or to control a PA Ready
lamp. (In the case of controlling a free-standing lamp or other indicator, a third-party
RS232-to-TTL convertor or circuit will need to be installed to convert the signal from
standard RS232 levels to whatever is required by the indicator.)
The levels provided by the PA Ready cable are standard RS-232 levels:
• +5 to +15 volts for high output state
• -5 to -15 volts for low output state
Use following pinout information to connect this cable to your equipment.

In addition to this hardware connection, you must also configure the correct serial port and
the nature of the signal trigger. For more information, see Serial USB Comm Port PA
Ready on page 87 and PA Ready Control Signal on page 87. You may also have to
configure any third-party equipment that is connected to recognize the signal and respond
to it by changing the state of an indicator.

Tip If your console computer does not have a suitable serial port, you
can use a 25-to-9-pin serial adapter or a USB-to-serial adapter. Not
all USB-to-serial adapters work properly. For more information, see
Installing the USB-to-Serial Bridge on page 101.
Note In the FSA Server Global Settings, the Serial USB PTT COM Port for
PA Ready must have a specific COM port assigned and the active
state for the PA Ready signal must be set as Positive or Negative
trigger.
See the
Fire Station Alerting System Operation manual, part
number 025-9582, for an explanation of the behavior of the PA
Ready signal in regards to the use of Day mode or Night mode
operations.
