3.9.2
ARM/DISARM
This command is used to arm and disarm the PET-820. Once an alarm occurs and the PET-820 has called a pre-programmed
telephone number, the user must issue the disarm command in order to stop the PET-820 from issuing the alarm status and
re-calling the telephone number again. To arm the PET-820 all inputs must be in the normal or clear condition. If the input
is not in a clear condition when the arm command is issued the PET-820 will identify the error. The error must be corrected
or the input must be turned off in order to arm the PET-820. When using the "Arm/Disarm" command, the ON/OFF
(Zero/Non Zero) information is not required. If it is not used, an arm condition will change to disarm or the disarm condition
will change to arm.
The analog input alarm mode is armed and disarmed in conjunction with the standard digital input alarm mode Once an
analog alarm occurs the PET-820 will not respond to the digital inputs and the analog alarm itself will respond in the same
manner as it does for the digital input. If you wish to only operate the PET-820 using analog alarms, you will need to disable
all unused digital input (reference the programming command code 30 for this operation).
COMMAND CODE:
01
COMMAND SYNTAX:
01 [key Code] <ON/OFF> #
READ BACK SYNTAX:
01 #
WHERE:
Key Code = reference current key code
ON/OFF = Zero (0) or Non Zero (1-9)
EXAMPLE:
01 11 1 = Turns the Arm mode ON
01 11 # = Toggle the Arm from ON to OFF condition
01 # = Read back the current Arm condition

READ BACK LOOP STATUS
This command may be used to interrogate each of the input loop circuits current status or the current status of all input loops
circuits. The read back dialogue will indicate "Set" if a loop circuit is a non-normal condition. The dialogue for a normal
loop circuit condition will be "Clear". When using this command, if you leave out the loop information all 8 loops will be
interrogated.
COMMAND CODE:
02
COMMAND SYNTAX:
02 [Key Code] <Loop> #
WHERE:
Key Code = Reference current key code
Loop = 1 through 8
EXAMPLE:
02 11 3 # = Read back current condition of loop circuit 3
02 11 # = Read back current condition of all eight loop circuits
3.9.4
READ BACK LAST ALARM STATUS
This command may be used to read back the systems most recent alarm. If your system was ordered with the RAM/RTC
option, the read back of the alarm status will also include a date and time stamp of when the alarm occurred. This command
operates the same for both digital and analog inputs. The read back of an analog alarm status will always include a Date and
Time stamp due to fact that the RAM/RTC option is required.
COMMAND CODE:
03
COMMAND SYNTAX:
03 [Key Code] #
WHERE:
Key Code = Reference current key code
EXAMPLE:
03 11 # = Read back most recent alarm
