COMMUNICATION
5.0 COMMUNICATION
The PET-820 is equipped with the latest technology in digital speech synthesis capable of reporting a different alarm
condition for each loop circuit. The PET-820 can dial up to ten different 32 digit telephone numbers using either rotary dial
pulse or touch-tone dialing.
Multiple PET-820s can be connected to a single telephone line or twisted pair of wires. The access to only one of the units is
then done by issuing the designated unit's Password. It should be noted that telephone and ringing voltages are not required
in order to operate the unit.
This section includes a detailed description of the communication programmable features and operations. Reference
SECTION 4.0 and APPENDIX B for a full listing of the communication programming commands.
5.1 SPEECH COMMUNICATION PROTOCOL
The PET-820's speech synthesizer is the principal means for the PET-820 to communicate with the user. This
communication occurs during the command mode, programming mode and alarm mode. In the command and programming
mode, speech is used to respond to the data input sent by the user. In the alarm mode, speech is used to identify the source of
the alarm. The following is a brief description of what you should expect when communicating with the PET-820.
5.1.1 SIGN ON MESSAGE
After the PET-820 has counted the pre-programmed number of rings, it will pick up the receiver (Off Hook) and respond with
the appropriate pre-programmed message "P E T eight twenty" or, if RAM / RTC option has been installed, the message will
be "Good Morning/afternoon/evening the time is (current time) on (current date)". These messages are programmable,
reference SECTION 4.0 for more information on changing this message.
5.1.2 CONTROL AND PROGRAMMING MODE
When the proper command is sent for controlling and programming the PET-820, a voice response (referred as READ BACK
in this manual) of the current or most recently changed date will occur. When the format or data within a command is
incorrect, the PET-820 will not respond, this was done as not to encourage unauthorized use of the system. Reference
SECTIONS 3.0 and 4.0 for more information on the READ BACK format.
5.1.3 ALARM MODE
Once the PET-820 has been armed and an alarm condition occurs, the PET-820 will go OFF HOOK and dial the
preprogrammed telephone number. When the dialing is finished there will be a pause before the first message is sent. The
PET-820 will repeat this message for the preprogrammed number of times before it gives up and hangs up the phone. This
delay and message repeat should allow the user enough time to identify the message and disarm the unit. All of the
parameters and messages described here-in are programmable, reference SECTION 4.0 for more information on
programming these parameters.
