OPERATE PROCEDURE
Rather than using examples of all commands, you will only ARM the PET-820. This is done by issuing the command code
01, the default key code 11, the data which will be 1 for arm and #, [01 11 1 #]. The read back telemetry will say "ON". You
may now disconnect the communication by sending [00 #], the read back telemetry will say "Good-by Telephone Call
Complete". At this point the system is now armed and ready to use. Before continuing we suggest that you re-establish
communication via the method that was pre-described and issue the disarm command [01 11 0 #] as described in the operate
section of this manual. Unfortunately at this point you have not programmed a telephone number or other pertinent
information in order for the PET-820 to respond to an alarm properly.

PROGRAMMING PROCEDURE
Reestablish communication with the PET-820 as described in paragraph 2.3. Once the password has been sent, you are ready
to access programming you must enter the program authorization code, the default program authorization code is [61 987654
#]. If the PET-820 responds with "P A C switch is off" this means that the circuit board programming switch is currently in
the off position. Without disconnecting or turning off power, change the circuit board programming switch (the right hand
switch located next to terminal 23) to the ON position and re-issue the program authorization code. The PET-820 should
then respond with "P A C O K" you are now ready to change the operating characteristics of the PET-820.
The first item that you will attempt to do is programming a telephone number, this will enable the PET-820 to call with an
alarm message. Using program command code 22, you enter [22 telephone number and ##]. The PET-820 should then read
back the telephone number that you just programmed. If you wish to recheck this number, you can enter [22 #] and the
PET-820 will then read back the number.
Once you have completed this task, re-arm the PET-820 using the command code [01 11 1 #] the PET-820 will respond with
"ON". Then issue [00 #] to end the telephone communication. Now the PET-820 is armed and waiting for a change to one
of the loop circuit inputs. You should be able to identify this conditions from the right hand status LED, located between
terminals 12 and 13, first flashing red and green indicating arm delay, then flashing red at a slower rate indicating armed. If
you take the loose end of the wire that you connected to the terminal 2 and short it to terminal 1, you should notice that the
LED status indicator is flashing at a faster rate or is steadily on. After the alarm time delay the PET-820 will then call the
telephone number that you just programmed and read back the pre-programmed message associated with that alarm input.
Once the PET-820 has established communication and you have received this message at least one time you may disarm the
system by entering the password as pre-described [60 321 #] and disarm command [01 11 0 #]. The PET-820 will then
respond with "OFF". Then you may enter [00 #] to terminate the communication.
We have now reviewed some basic operations of the PET-820 and you should review sections 3.0 OPERATING and 4.0
PROGRAMMING. Get familiar with the different operating and programming commands that are available for your use.
