Barnett Engineering ARU CV2 instruction manual What if an alarm is not acknowledged?

Operations Overview 1-5

1.6 What if an alarm is not acknowledged?

When the last line in the directory has been completed without receipt of an Acknowledge Code, a two-stage timer is used to determine when the directory sequence is repeated again. This timer has two sections: a Short Timer which operates for the number set in Short Cycles, and a Long Timer which begins after the Short Timer has completed its cycles. This provides a means of varying the repetition cycle over a period of time.

1.7 What do you want the Cv2 to do when you call it?

In addition to reporting alarms, the Cv2 will also answer incoming calls. This allows you to interrogate the unit, operate control outputs and change shifts. You can control the level of security that is presented to incoming calls. With the lowest level, the call will be answered with the Site ID phrase, the phrases for any groups that have alarms, followed by the prompt “Enter Command Code”. An Access Code is not required. At the next level of security, the Cv2 will announce the Site ID phrase and then wait ten seconds for the password code before 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.

1.8 Sending remote control commands

Points designated as outputs 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.
