ANALOG INPUT CONNECTIONS
The following section outlines connections that are importation to the analog option. If your unit dose not contain this
option, skip to section 6.5 . The maximum voltage that to be applied to any one of the analog inputs should not exceed
±
5.50 volts. Make sure that the your voltage source can not go beyond these limits. Refer to figure 6.2 for additional
information on connections.
1.
Turn off the power switch.
2.
Connect analog signal to their appropriate input channels.
3.
Connect all un-used analog inputs to ground. The ground terminals are 2, 5, 8, and 11.
4.
Make sure that all analog signals that you have connected, can not swing beyond +/-5.50 volts.
5.
Turn on the power switch and you are now ready to use the analog input option.

PROGRAMMING CHANGES
Using your installation planning and the tables in "APPENDIX B". Establish contact with the PET-820, send the password

GENERAL SYSTEM TESTING
1.
Once programming has been completed, re-establish communication with the PET-820 and arm the system. If an
error message occurs, the message will identify the loop circuit in which the error occurs. Trouble shoot your
connections in order to delete the error. Re-arm the PET-820 and end communication with the PET-820.
2.
Force an alarm condition, by shorting or opening the appropriate loop circuit as required to simulate an alarm
condition.
3.
Check for the end result of the alarm, whether it has been a telephone that has been dialed or relay contact that
closes. Either way, confirm that the system responded according to your programming plans.
