4.5.23 CHANGE LOOP CONFIGURATION, SELECT RESPONSE TIME

Each loop circuit can be programmed to use one of two different response times. The response time is used to ignore a
momentary change in contact closure that is undesirable. It is recommended that no less than 40 milliseconds response time
is used. In an applications where an unwanted contact closure may occur for one to two seconds and you do not want to
detect this closure as an alarm. A three seconds response delay may be programmed for that input and all contact closures
that occur for less than 3 seconds will be ignored as an alarm.

COMMAND CODE:

34

PROGRAM SYNTAX:

34 [Loop] [Data] #

READ BACK SYNTAX:

34 [Loop] #

WHERE:

Loop = 1 through 8, identifies the loop for change
Data = 0 or non zero, 0 = response time #1, non zero = response time #2

EXAMPLE:

34 1 2 # = Selects response time #2 for loop circuit #1

DEFAULT:

All loops = 0

4.5.24 CHANGE LOOP CONFIGURATION, SELECT ALARM MESSAGE

Once an alarm has occurred and the PET-820 has established telephone communication with the user, the PET-820 will read
back 1 of 16 different messages. The message that is read back corresponds to the message number that has been
programmed for the loop circuit that generated the alarm. Each of the 8 loop circuits may be programmed to read back
anyone of the 16 different messages during the alarm condition.

COMMAND CODE:

35

PROGRAM SYNTAX:

35 [Loop] [Data] #

READ BACK SYNTAX:

35 [Loop] #

WHERE:

Loop = 1 through 8, this identifies the loop for change
Data = 00 through 15, identifies the message buffer to speak during an alarm communication

EXAMPLE:

35 2 03 # = Loop circuit will speak message buffer 03 during an alarm

DEFAULT:

Loop circuit 1 = Message buffer 08
Loop circuit 2 = Message buffer 09
Loop circuit 3 = Message buffer 10
Loop circuit 4 = Message buffer 11
Loop circuit 5 = Message buffer 12
Loop circuit 6 = Message buffer 13
Loop circuit 7 = Message buffer 14
Loop circuit 8 = Message buffer 15

4.5.25 LOOP CONFIGURATION, SELECT MONITOR OUTPUT

When the alarm monitor function has been turned on, any of the 8 loop circuits that have been programmed to output to the
relay or digital output will do so when that loop circuit is abnormal. Note that both the relay and digital outputs share other
functions and when using this feature the user should consider how it might affect other features that also operate the relay or
digital outputs.

COMMAND CODE:

36

PROGRAM SYNTAX:

36 [Loop] [Data] #

READ BACK SYNTAX:

36 [Loop] #

WHERE:

Loop = 1 through 8, this identifies the loop for change
Data = 0 through 3,

0 = no output

1 = relay output

2 = digital output 3 = both output

EXAMPLE:

36 3 02 # = Enable loop #3 for digital output

DEFAULT:

All loops = 0
