located on each DV message PB. For the SP40S firmware, a flashing LED indicates that the
PB activated a message, and a solid LED indicates that a CC activated a message.
3.5.2.2 Operation of the Digital Voice Messages with the SP40S-D firmware
Each PB and CC for DV messages 1 through 6 are individual inputs each having their own
10-minute timer. If one of the inputs goes active its associated timer starts, the associated
message starts playing, and if the input does not restore, the input’s timer will time out and
the message will stop playing. The input must restore before it can go active again,
triggering the message to play.
Example 1: CC1 goes active, its timer starts and message1 starts playing. If CC1 does not
restore, the timer will expire and the message will stop playing in 10 minutes. Once CC1
times out, CC1 cannot trigger message1 to play again until CC1 restores. You can,
however, press PB1 and message1 will start playing again and will continue for 10 minutes
if PB1 remains active. If PB1’s timer is allowed to time out also, message one cannot be
triggered by anything now since both of its associated inputs are still in “Timeout” mode.
One or both must restore and re-activate for message1 to start playing again.
Example 2: CC1 goes active, its timer starts and message1 starts playing . 8 minutes into
the timer PB1 goes active which start PB1’s timer and message1 continues to play for
another 10 minutes. This makes the total play time 18 minutes in this example if neither
CC1 nor PB1 restores and re-activates. It is possible that lower priority messages may not
be heard at all because of a higher priority message’s inputs being restored and re-activated
while the lower priority input times out.
DV message 7 and 8’s inputs (PB & CC) do not have a timer associated with them and will
continue to play message 7 or 8 until the input restores or a higher priority input goes active.
Example 3: PB7 activates which starts message7 playing. This message will continue
playing as long as PB7 remains active. CC1 goes active, its timer starts, CC1 is a higher
priority message, so message1 is heard instead of message7 now. CC1 remains active
through the 10 minute timer and the timer times out shutting off message1. Message7 starts
playing again at this time because PB7 is still active.
The addition of the timeout functionality in the SP40S-D firmware causes the user interface
on the SP40S to indicate that a particular DV input is in timeout.

Message LED Description
STEADY OFF Both the PB and CC input for the DV message are INACTIVE.
STEADY ON The DV message input is ACTIVE as a result of either PB or CC activation.
ONE BLINK The CC input for the DV message is in the TIMEOUT state and the PB input is
INACTIVE. Deactivating the CC input will cause the LED to turn off as both
inputs become INACTIVE.
TWO BLINKS The PB input for the DV message is in the TIMEOUT state and the CC input is
INACTIVE. Deactivating the PB input will cause the LED to turn off as both
inputs become INACTIVE.
THREE BLINKS Both the CC input and the PB input for the DV channel are in the TIMEOUT
state.
