indicated in the scrolling message, one represents 300 baud, two represents 600
baud, etc. The highest acceptable value is four, which represents 2400 baud. Press

4.3.12 FUNCTION 11 (SETTING REQUEST TO SEND TIMING)
Note: This function is automatically downloaded from the SYSTEM 3505
PRISM LX when the SET button is pressed in the MULTIPLEX ADD/CHANGE/DEL
mode or when SYSTEM 3505 PRISM LX restarted.
The SYSTEM 3505 PRISM LX and DGM panels communicate over the
communication loop using small data packets. Each data packet is preceded by a
Request To Send signal which announces that a data packet is about to be sent.
Sometimes, because of excessively long lines or noise on the loop, the length of this
Request to Send signal must be modified so the announcement can be transmitted
properly. Normally this function is set by the factory and should not modified.
Function 11 can be programmed from one to 255 milliseconds.
Note: If Function 11 is set improperly, it will not permit the SYSTEM 3505
PRISM LX and the DGM panel to communicate.
To view or change Function 11, press “11”, FUNC or, if you are viewing the previous
function, just press FUNC. The second line of the display
will read “11 - Set
RTS=040.” A message will scroll on the first line:
The RTS timing is 040 milliseconds long. Set by SYSTEM 3505
PRISM LX, do not change. Press CLR/SIL to clear display or FUNC
to view next Function.
Enter the new number, representing length of the RTS signal, then press ENTER. If
the number entered was out of the range, a message will display to indicate that the
value was not valid, and the original RTS timing will display. Press CLR/SIL to clear
the display. Press FUNC to advance to the next function.
4.3.13 FUNCTION 12 (SETTING ZONE DELAYS ON REPORT)
Each zone in the panel can be programmed with a one to 90 second delay. An
alarm condition on a zone would have to remain constant for the duration of the
delay before it
would be accepted and transmitted to the SYSTEM 3505 PRISM LX. If no delay is
desired, program a zero value for the zone. The default value for all zones in the
DGM panel is zero. To view or change Function 12, press “12”, FUNC or, if you are
viewing the previous
function, just press FUNC. The second line of the display
will read “FUNC 12 ZN1_
00.” A zone number and respective delay are represented. A message will scroll on
the first line:
Zone Delays. Set a delay of 0 to 90 seconds for each zone. READ
button selects zone to view or update. Enter the new value, then
press the ENTER button. The IN/OUT button will change all of the
zones in the panel at one time. Press CLR/ SIL to clear display or
FUNC to view next Function.
