SYSTEM DESCRIPTION
1.0 SYSTEM OVERVIEW
The PET-820 system is shipped from the factory ready for use. It comes pre-programmed with factory basic default settings
that fit most all applications. The system can be re-programmed from a standard telephone or the optional keypad display in
order to meet a variety of needs. All loop circuit alarm characteristics and communication parameters are programmable for
most any applications that may occur.
The PET-820 comes standard with 8 dry contact inputs (loop circuits), one relay output and one digital output. The relay
output is completely programmable as to both alarm and/or control functions.
1.1 FACTORY DEFAULT SETTINGS AND PROGRAMMABLE PARAMETERS
No special tools are required for programming and control of the PET-820. A simple connection to a standard telephone line
is all that is required to communicate with the PET-820 system. Before attempting to program with new characteristics,
review the programming tables provided at the end of the manual. If any of the default settings described in this table do not
meet your installation requirements, you can easily change these settings using a touch-tone telephone or the optional keypad
display panel.
1.2 PROGRAMMING LOOP CIRCUIT CONFIGURATIONS
The PET-820 has 8 loop input circuits that can be defined as normally open contact, normally closed contact or a resistor
supervised contact. Each of the inputs defined as resistor supervised contacts may be wired with a combination of normally
open and normally closed devices. Loop circuit #8 may also be re-programmed to accept a momentary switch closure for
ARM/DISARM control. Refer to the programming section of the manual for more information on this subject. Use the
programming table in "APPENDIX B" to provide additional assistance in planning the loop circuit and system configuration.
1.3 CONTROL AND PROGRAMMING
The PET-820 implements three levels of security. The first level is a Password. When communication is established with
the PET-820 via a telephone, the user must enter a Password in order to continue with operation or programming. The
second level of security is the Key code. The key code is used in conjunction with some command codes to provide
additional security when operating the PET-820. The third level of security is the Program Authorization Code (PAC).
This code is required in order to change or alter any of the configuration data. Without the Password and Program
Authorization Code none of the systems parameters may be altered. The PET-820 provide one additional level of security
for the programming mode. This is a program enable switch that is located in the main circuit board. When this switch is in
the OFF position, the user will not be allowed to access the programming mode. If programming is desired, you must turn
this switch to the NO position.
1.4 RAM and REAL TIME CLOCK OPTION
If your unit has included the RAM/RTC option, you will fine that some of the PET-820's operations are enhanced. These
enhancements include the following.
1.
Increased the number of message buffers from 2 to 16, that can be modified.
2. Increase the number of telephone numbers form 2 to 10, that can be stored.
3. Add date and time stamp to the alarm. When alarm message is received, the date and time of the alarm will be
included with the message.
4. This option is required in order for the analog option to operate.
