BARNETT ENGINEERING LTD. ProTalk Cv2
allowing access to alarm information or other control functions. At the highest level, the call
is answered but there are no voice prompts; the caller has ten seconds to enter the Access
Code.
Each group of alarms has its own Interrogate Code. When the code is entered, the alarm
status for points in that group is spoken. For digital and watchdog points, the stored phrase
for that point is spoken. Analog points are spoken with the stored phrase and its status -- high,
low or normal -- followed by the reading. For totalizers, the stored phrase is spoken first
followed by the current accumulated value. Interval timers respond with the stored phrase and
the last captured interval.
Control outputs respond with the stored phrase followed by either ‘On’ or ‘Off’ indicating
their current state.
The presence of incoming calls is indicated by the ringing sound from the speaker and at one
of the outputs if it is selected to show ringing.
2.1.8 Sending remote control commands
Controls can be controlled using the programmed codes. These codes can be sent to the Cv2
either during a reporting sequence or when a call is placed to the unit.
During the alarm reporting sequence, the control codes may be sent after the “Enter
Acknowledge Code” prompt is heard. For the next five seconds, the Cv2 will accept
Acknowledge, Interrogate or Control codes. With each received code, the command will be
performed and a prompt for another command entry will then be spoken. For a remote control
output, the status of the output will be spoken after the received code has been executed.
When the unit is called and after the Access Code, if required, has been entered, the prompt to
“Enter Command Code” will be issued. In either case, the call will be terminated if a valid
code is not received during the ten second window.
2.2 Cv2 Capabilities (Basic mode)
When an alarm occurs, the Cv2 places a call using its built-in cellular phone and announces
the alarm condition using stored voice messages. Alarm messages consist of the site ID
phrase and the alarm message phrase that are stored at voice programming time. The unit can
also be called up and interrogated to obtain current alarm conditions.
The Cv2 has eight alarm inputs that are programmed as conventional digital inputs, set as
either high or low to indicate an alarm.
The three user controls can be set to operate as either on/off controls or as timed controls. The
other five controls are always set to indicate New Alarm, Any Alarm, Acknowledge Received,
Modem Carrier Detect and Ring Out.
