GETTING STARTED
2.0 BENCH TESTING
The following paragraphs provide a method for becoming familiar with the PET-820 prior to understanding all of its
capabilities and detailed operational characteristics. This test assume you have nothing more then the PET-820, a screw
driver, some wire and a keypad display panel or telephone communication via central office telephone lines or a PBX. You
may also need an adjustable voltage source (0 to 1.5 volts minimum) if your unit has the ANALOG option. The following
steps will take you through hook up, operation and limited programming of the system.
2.1 UNPACKING THE PET-820
Inspect the carton for the following contents and if any of these items are missing or damaged, notify your PET-820 dealer
immediately.
1. PET-820 user manual
2. PET-820
3. Miscellaneous hardware package
4. Three prong line cord with liquid tight strain relief.
2.2 START UP PROCEDURE
The following is a start up procedure for the PET-820. Default password, key code, and Program Authorization Code are used
in the examples. Refer to figure 6.1 for detailed hook up diagram of the PET-820.
1. Remove the 2 screws from the lower terminal cover of the PET-820, then remove the cover.
2. If your PET-820 includes the battery option, connecting the AC power at this time is not necessary. With power
turned off (the left hand switch next to terminals 20, 21, and 22) connect the three prong line cord, black to terminal
20, white to terminal 21 and green to terminal 22 as shown in figure 6.1. It is very important to re-check this
connection before applying power to the unit. You can check the connection by turning off the power switch and
plugging in the cord. With a standard AC voltmeter on the AC scale, check the voltage from terminal 21 and 22,
there should be less than 3 volts AC. If this test fails, then re-check your wiring and/or have an electrician check the
AC outlet for proper wiring.
3. Connect a telephone line to terminals 13 and 14 or you may use the keypad display. If telephone lines, PBX or
keypad display are not available, refer to the diagram in "APPENDIX D" for information on building a simulated
telephone interface test circuit.
4. Using a 6" long wire, strip 1/4" at both ends and connect one end to terminal 2.
5. Turn on the power switch (the left hand switch near terminals 20, 21 and 22). You should observe that the left hand
green LED on the circuit board or the LED labeled operate on the front panel, if keypad option was included, is on
and not flashing. If the LED will not turn on or is flashing, consult the trouble shooting section of this manual for
further information.
