1. Getting Started

The Cv2 is a very flexible device capable of monitoring discrete or analog inputs and reporting alarm conditions at these inputs. It is also capable of controlling multiple outputs. Before the Cv2 is placed into service it must be programmed for the type of operation you require.

The Cv2 contains an embedded CDMA transceiver. To activate the internal CDMA module, you must do the following:

# If you do not already have a network service account you will need to contact a desired

network service representative and setup an account.

# For activation you will need to provide the ESN of the unit, the ‘home’ location where it

will be installed as well as a billing address and contact name.

# Your network service representative will provide a 10 digit telephone number that you will

program into the unit.

This can be done using the PC configuration software or a telephone set connected to the Cv2. To use the programming application install the software according to the instructions in section 4-1, connect the powered Cv2 to the computer with the cable provided then activate the transceiver programming function by selecting Program/Cellphone from the menu. Enter the 10 digit telephone number where shown and press the Store button to transfer the number into the unit.

To program the mobile number with a telephone set, plug the set into the programming port of the powered Cv2 and take the set off-hook. The Cv2 will respond with “Enter Program Code” when you take the set off-hook. Follow this sequence:

You: enter the digit 9

Cv2: “ESN is 067 point 12345678" . . . . . . . . . . . . . . . . (unit speaks ESN)

You: enter the digits ** . . . . . . . . . . . . . . . . . . . . . . . . . . (advance to MIN)

Cv2: “Mobile Number is 800 555 1212 . . . . . . . . . . . . . (unit speaks MIN)

You: enter the digits 800 268 2646 ** . . . . . . . . . . . . . . (change the MIN)

Cv2: “Mobile Number is 800 268 2646" . . . . . . . . . . . . (unit speaks new MIN)

You: enter the digits ** . . . . . . . . . . . . . . . . . . . . . . . . . . (accept the new MIN)

or re-enter the MIN and repeat the process Cv2 “Enter Program Code” (unit returns to the main program menu) You: hangup - the number programming is completed

Read this manual carefully before proceeding with the installation and programming of the Cv2. There are two modes of operation available: Advanced and Basic. In Basic mode multiple Advanced functions are combined into a single Basic function for ease of programming. When the unit is configured for Basic operation, all of the variables that can be set by the PC during a programming session can also be modified remotely by calling the unit with a TouchTone telephone. Advanced mode operation allows full use of all functions in the Cv2 but limits the items that can be remotely modified.

Basic mode eliminates the need to configure the Hardware Inputs, Groups and Points by combining them into a single function called Alarms. Similarly, the outputs are reduced to a

B1272M001

BARNETT ENGINEERING LTD. ProTalk Cv2

Getting Started 1-2

single function called Controls. The number of directories is reduced from 6 to 2 in Basic mode. It is possible to retain the Advanced directory commands even if the overall programming is set for Basic operation.

It is important to establish whether Basic or Advanced programming is suitable for your application. The mode is set by the configuration uploaded from the PC and cannot be altered using the programming phone. It is possible to switch programming modes during the PC programming session. When changing from Basic to Advanced there is no loss of data so it is possible to quickly setup a unit in Basic mode then switch to Advanced to add some extra functions. Keep in mind that remote programming capabilities are very limited in Advanced mode. Changing from Advanced to Basic mode will destroy all of the programming information except the directories which have the option of remaining in Advanced mode.

All of the telephone numbers that are entered into a directory should be carefully checked to ensure that they are valid numbers. After the Cv2 has been programmed, a test should be performed to confirm that these numbers are called correctly. The Cv2 has built-in network protection that will alter the operation of the Cv2 if invalid numbers are called.

To prevent excessive failed calls on the cellular network, the Cv2 has a built-in method for counting unacknowledged calls. This process works by counting the number of unacknowledged calls that have been made and then taking action to alert the user that a large number of failures are taking place. If the problem is not corrected and the Cv2 continues to place failed calls it will eventually stop calling.

Rules for this process are: The number of unacknowledged calls is counted for each directory; receipt of an

acknowledgment resets the counter. A retry on the same number is not counted. If the counter exceeds 50 a “directory alarm” is created. This alarm is not latched and will be

cleared when an acknowledgment is received. This “directory alarm” appears as a new alarm in all groups causing each group to call out and

notify the user that the alarm is present. This alarm is announced before the Site ID by speaking “Directory X Error” where X is the directory that has failed to be acknowledged for at least 50 call out cycles.

If an interrogate code is received, the “Directory X Error” message will be made before any group alarms.

If the total number of unacknowledged calls in all directories exceeds 75, a call will be made to Barnett Engineering with the MIN and ESN of the phone. This information will be used to attempt to locate the owner of the equipment and notify them of the problem condition. At this point the timer used to control the interval between the last call in the directory and when the cycle is restarted at the first number will be set to 4 hours regardless of the program settings.

If the total number of unacknowledged calls exceeds 100, the Cv2 will cease to call out. The Cv2 will still answer incoming calls and reset the counters if an acknowledge code is received.

Each chapter has separate sections for Basic and Advanced operations. Once the mode that you want to operate in has been established, use the applicable section in each chapter.

A comparison or the functions available for each mode is shown in Table 1.

2. Operations Overview

The purpose of this chapter is to provide an overview of the Cv2 capabilities. Chapter topics are organized in the same order that you would follow in setting up the system. For more details on configuring the operation through the programming software, refer to Chapter 3, Configuration.

2.1 Cv2 Capabilities (Advanced 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, the group phrase and the alarm message phrase that are stored at voice programming time. The group phrase is used if the alarms have been grouped to provide different activities for different alarm conditions. The unit can also be called up and interrogated to obtain current alarm conditions and readings.

The Cv2 has eight hardware inputs that can be programmed to accept either digital or analog signals and eight hardware outputs. Inputs can be independently configured to operate in these modes:

digital monitoring contact closures or voltage levels watchdog monitoring for the absence of a periodic event totalizer counting events interval measuring the time duration of events analog measuring 0 to 5 volt signals

Outputs can be set to operate as either on/off controls or as timed controls.

2.1.2 What constitutes an alarm?

Alarm conditions can be defined for digital, watchdog and analog inputs. Totalizers and interval inputs are used for measurement purposes and do not generate alarms. The signal at the input is conditioned by a debounce timer that ensures the level is valid before accepting it.

A digital input has normal and alarm states that can be defined as either when the input is high or low. After the input signal has been qualified by the debounce timer, it can be registered as an alarm when the input is active, or it can be latched to detect a pulsed condition. The voice message for a digital input is programmed to announce the alarm condition that it is monitoring, e.g. “Intrusion Alarm”.

Watchdog inputs use a timer that is restarted by changes at the input. If this timer expires because it has not been restarted within the programmed interval, an alarm will register. Like the digital input, the watchdog can be set as either an active-only or latched alarm. The voice message for a watchdog is similar to a digital, e.g. “Tower Strobe Failure”.

Analog inputs convert the voltage level to a digital value and perform a comparison against the programmed low and high setpoints. An alarm is present when the measured value is above or below the setpoint. Alarm messages are spoken using the stored phrase with either

B1272M001

BARNETT ENGINEERING LTD. ProTalk Cv2

Operations Overview 2-2

“High” or Low” appended depending on which setpoint has been exceeded. The actual reading, including decimal place notation and engineering units, is spoken when the Cv2 is interrogated.

The latching alarm function is also available for analog inputs.

2.1.3 How are alarms processed?

The way in which the Cv2 processes alarms is shown in Figure 1. The hardware input and output ports are activated in the Points section to become part of the

monitoring and control process. There are 30 points which can be referenced to any of the I/O ports. This allows an analog input to be used by more than one point and monitored for multiple setpoints, as would be the case where minor and major alarms are required.

If you do not want all of the points to generate the same response when they detect alarms, they can be placed into different groups. Six groups are available, each with independent timers and control codes. When a group detects an alarm condition in one of its assigned points, it executes the sequence of actions found in the current directory. A group can use any of the six directories to perform the call out function, plus the directory selection can be changed by using the shift control feature.

B1272M001

BARNETT ENGINEERING LTD. ProTalk Cv2

Operations Overview 2-3

2.1.4 What actions should occur when an alarm is detected?

All alarm conditions will be processed by placing a call on the cellular phone. The called number and the activities that occur with different alarms are determined by entries in the directories. A directory contains the sequence of actions that will occur when a group has an active alarm. Instructions for dialing, speaking, inserting delays and signaling are placed in the directory in the order in which they are to be performed. There are a total of six directories; each can contain a unique sequence of activities that will be performed when alarm conditions exist.

To best describe how a directory controls alarm reporting activities, an example directory programming session follows. For more information on the directory summary and dialog box, refer to Chapter 3. The opening window for a directory displays a summary of the activities that it will perform when an alarm is detected. The directory summary is arranged as lines; each line represents the sequence of events that will take place during one call out. If a Dial command is the first entry on the line, the Cv2 will call the programmed number and then execute the remainder of the commands on that line. After the last command on the line is competed, the call will be terminated. Commands such as Auto Ack and Wait, when used as single line commands, do not initiate a call. For a basic sequence where the Cv2 is to call a phone number and speak the alarm message, the directory line contains the Dial and Voice commands appearing as:

1. [DIAL]2458829 [VOICE]

This line will cause the Cv2 to place a call to 245-8829 and then speak the Site ID, Group Name and alarm message, or messages, for all active points. Unless programmed not to, the Cv2 will append the phrase “Enter Acknowledge Code” at the end of the alarm announcement and wait for the code to be returned. If the code is received, the alarm sequence will be terminated until a new alarm occurs. Failure to receive an Acknowledge Code will advance the sequence of operations to the next line in the directory. If the commands contained in the last directory line have been completed without reception of an Acknowledge Code, the Cv2 waits for the time interval set in the timers before repeating the process by starting over at directory line 1.

During execution of the Voice command, the Cv2 will try to announce the alarm messages three times with a one minute limit for the total announcement duration.

For example, to call four telephone numbers, the directory would appear as:

1. [DIAL]2458829 [VOICE]

2. [DIAL]2336700 [VOICE]

3. [DIAL]9842121 [VOICE]

4. [DIAL]9843316 [VOICE]

If you want an alert tone to precede the voice message the directory line would look like this:

1. [DIAL]2458829 [ALERT] [VOICE]

The next example shows a sequence that is used to call a numeric paging terminal. After the call is placed there is a four second delay for the paging terminal to respond before the Cv2 sends the number to be displayed on the pager. When calling a paging terminal, it is sometimes useful to allow the called party time to call the Cv2 back and acknowledge the

B1272M001

BARNETT ENGINEERING LTD. ProTalk Cv2

Operations Overview 2-4

alarm before the Cv2 advances to the next line in the directory. This can be done by using the Wait command on its own line; the entry below will cause a four minute delay before the next line is executed.

1. [DIAL]2458829 [WAIT]4 [DTMF]4567

2. [WAIT]240

Directory lines can be added, removed, or modified and new lines can be inserted between existing lines.

2.1.5 How do you want to respond to an alarm call?

After the Cv2 has finished speaking the alarm messages, it prompts the called party with the phrase “Enter Acknowledge Code” and then waits five seconds for the code to be returned. If the code is received, it will terminate any further call out activities until a new alarm occurs; otherwise, it will proceed to the next line in the directory. There is a Temporary Acknowledge Time that can be set in the General section that will override the operation of the Acknowledge Code. If the temporary time is set to a value other than Off, and the received Acknowledge Code has the digit # appended to it, the Cv2 will remain in the acknowledged state only for this time interval. After the timer has expired and if the alarm condition still exists, the Cv2 will resume alarm reporting. This feature is used as a safety measure to ensure that an alarm cannot be acknowledged and then left unattended.

Each group has its own Acknowledge Code which only affects points that have been assigned to the group. Other groups with different Acknowledge Codes will continue alarm reporting if they do not receive their own code.

Using the Auto Ack command in a directory will cause the Cv2 to automatically acknowledge any alarms that are in the group using the directory. This feature must also be enabled for that group, since other groups of points may be using the same directory. Auto Ack must be on the last line in a directory since any further commands will never be executed.

Another method of acknowledging the Cv2 is by activating the special function that allows hardware inputs to be used as local acknowledge controls.

2.1.6 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.

2.1.7 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

B1272M001

BARNETT ENGINEERING LTD. ProTalk Cv2

Operations Overview 2-5

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)

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.

B1272M001

Operations Overview 2-6

2.2.1 What constitutes an alarm?

The signal at the input is conditioned by a debounce timer that ensures the level is valid before accepting it. An alarm has normal and alarm states that can be defined as either when the input is high or low. After the input signal has been qualified by the debounce timer, it can be registered as an alarm when the input is active, or it can be latched to detect a pulsed condition.

ACCESS

The way in which the Cv2 processes alarms in Basic mode is shown in Figure 2. The eight inputs can be activated in the Alarms section by selecting them to use either Directory A or Directory B for calling out. Each directory can have a unique list of telephone numbers for calling out as well as its own Acknowledge code, Interrogate code and Cycle timer for repeating the call out sequence. When a directory is edited in the Advanced mode it can have more commands than just dialing and speaking the alarms. The three control outputs are activated in the Control section by selecting On/Off or momentary operation and entering the DTMF control codes. There are also five hardware controlled outputs that are used to indicate New alarm, Any alarm, Ack received, Modem carrier detect and Ring out.

2.2.3 What actions should occur when an alarm is detected?

All alarm conditions will be processed by placing a sequence of calls on the cellular phone until an Acknowledge code is received. The called numbers are determined by entries in the two directories. Each call consists of dialing the phone number followed by a verbal message containing the Site ID phrase then any active alarm phrases.

B1272M001

BARNETT ENGINEERING LTD. ProTalk Cv2

Operations Overview 2-7

2.2.4 How do you want to respond to an alarm call?

Each directory has its own Acknowledge Code which only affects alarms that have been assigned to that directory.

2.2.5 What if an alarm is not acknowledged?

When the last line in the directory has been completed without receipt of an Acknowledge Code, the cycle timer is used to determine how long the Cv2 will wait before the directory sequence is repeated again.

2.2.6 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 and operate control outputs. When called, the Cv2 will announce the Site ID phrase and then wait ten seconds for the Access Code before allowing access to alarm information or other control functions.

Each directory has its own Interrogate Code. When the code is entered, all active alarms are spoken. 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 output 5.

2.2.7 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.

Operations Overview 2-8

2.3 Indicators

The Cv2 has four LED indicators to show the operation of the unit and to assist in troubleshooting.

When the Cv2 is initially powered up, the four LEDs will do the following:

C All will turn on for approximately one second. C Hook will flash on and off for one second then go out. C Tone will flash on and off for one second then go out. C Voice will flash on and off for one second then go out. C Alarm will flash on and off for one second then go out. C Hook On power-up, following the initial flashing of each LED, Hook flashes until

the Cv2 has found cellular service. Once the unit has logged onto the cellular network, the Hook indicator goes out. Hook also flashes while a call is being placed. After the call has been processed, Hook is on steady until the end of the call when it goes out.

C Tone Tone blinks once for each DTMF digit that is either received or transmitted. C Voice Voice is on when the Cv2 is speaking. On power-up, following the initial

flashing of each LED, it will go on continuously for 2 seconds if any section of the stored database, voice or vocabulary memory is corrupt. If this occurs, the configuration should be downloaded into the unit and the voice recordings checked for validity. Voice flashes briefly every second to indicate that the Cv2 is operating correctly.

C Alarm If an unacknowledged alarm is present, the alarm indicator will flash. When the

alarm is acknowledged, Alarm is on steady. When no alarms are present, Alarm is off.

2.4 Troubleshooting

Is there power to the unit?

When power is first applied to the Cv2, it will flash the Hook indicator until it establishes contact with the cellular service. At any other time, the presence of power, and correct operation, are indicated by the brief flashing of the Voice LED every second.

Does the cell phone work?

Use the local call feature to determine if the unit is working properly. If the call cannot be completed, query the cell phone to see if it responds - any parameter can be used here. Query the RSSI (Received Signal Strength Indicator) in the phone to see if there is coverage in the area. The message “error” will be returned if there is no coverage. This can possibly be corrected by improving the antenna system.

B1272M001

BARNETT ENGINEERING LTD. ProTalk Cv2

Operations Overview 2-9

Are the inputs connected properly?

For digital inputs that are programmed for standard digital operation, create an alarm condition on the input and confirm that the Alarm LED comes on. Make sure the input is applied long enough for the debounce to time out. If the Alarm indicator does not come on, the problem is not necessarily with the input connection. Check that the input is enabled as a valid point, the associated group is enabled, and the directory is programmed to call out..

For analog inputs (Advanced mode only), interrogate their group to hear the scaled value at the input.

The unit does not dial out.

Check the Alarm LED to confirm that an alarm is present. If this indicator is not flashing, the Cv2 will not call out. For Advanced mode programming, check that the input is enabled as a valid point, the associated group is enabled, and the directory is programmed to call out. For Basic mode programming, check that the alarm has a valid directory selected.

I cannot call into the unit.

If you receive a recording from the telephone company indicating the user is not available, there may be a problem with the installation or you may be calling the wrong number. Use the programming phone to confirm the telephone number in the unit.

Installation 3-1

3 Installation

The Cv2 can be installed before or after the configuration has been transferred from the PC to the unit. If the Cv2 is configured in the shop before it is installed in the field, all of the programmed parameters and voices will remain unchanged in the unit’s non-volatile memory.

3.1 Antenna r equirements

The ProTalk Cv2 is supplied with an 8" dual band articulating antenna. This antenna should be mounted vertically for best operation. The antenna installation must provide a separation distance of 20 cm (8") or more between the antenna and all persons to satisfy Maximum Permissible Exposure (MPE) compliance.

The embedded transceiver uses CDMA technology. This is a spread spectrum technology that allows many users to occupy the same time and frequency allocations in a given band/space. It relies on low power transmissions and is able to detect received signals at very low power levels. The addition of higher gain antennas does not usually result in a performance improvement but instead can compromise the performance of the neighboring devices. The best improvements can be made by selecting the proper antenna location and orientation where a vertical orientation outside any metal building or enclosure is best.

3.2 Mounting

The Cv2 is available in two versions: the packaged unit which is housed in an enclosure complete with a battery backed power supply and a programming phone set, or the standalone version which is the Cv2 alarm reporter without the above accessories.

3.2.1 Packaged model

The packaged model should be mounted onto a wall or other vertical surface in a location where the temperature cannot exceed the Cv2 rating.

Before connecting AC power, confirm that the setting of the voltage range switch on the power supply module is set for the correct input, either 110 or 220 VAC.

Connect AC power to the terminal strip on the power supply module. Connect the antenna or coaxial feed line to the remote antenna onto the TNC coaxial jack on the Cv2.

Connect the input and output signal lines between the Cv2 and the equipment that you want to monitor and control. Details of the input and output ports are discussed later in

3.2.2 Stand-alone model

The stand-alone Cv2 can be mounted on a flat surface. Make sure that there is enough room around the unit to make connections. The environment should be clean and dry, with an ambient temperature that does not go below -30oC or above +50oC.

Connect a DC power source to the terminals on TB2. The Cv2 requires up to 1.2 Amps to operate; the supply should be sized accordingly. Input power to the unit is protected by a Polyswitch current limiter. If a fault develops in the CV2, this switch will become a high resistance to prevent damage to the equipment

or the power supply. Once this switch has been activated, the fault must be removed before it will reset and allow current to pass through to the equipment.

Connect the antenna or coaxial feed line to the remote antenna onto the SMA coaxial jack on the Cv2.

Connect the input and output signal lines between the Cv2 and the equipment that you want to monitor and control. Details of the input and output ports are discussed in the next section.

3.3 Input port connections

The input ports can be connected to a variety of contact or voltage sources for monitoring purposes. Select a wiring configuration that matches your alarm source from one of the following arrangements:

3.3.1 Ground closure alarm signal

For alarm sources that appear as a ground closure, either through a mechanical contact or an open collector driver, the input should be wired according to Figure 5. If the input is normally open and goes to ground during an alarm condition, program the Hardware section for this input as “Normally High”. If the reverse is true, set the input to “Normally Low”.

3.3.2 +12 volt alarm signal

The input will accept an alarm signal that switches between 0 and +12 volts with the wiring arrangement shown in Figure 6.

If the signal switches between +12 volts and an open circuit, as in the case of a relay contact, the ‘B’ terminal must be connected to ground to ensure that the logic level goes to ground when the voltage is removed.

Figure 6 +12 Volt Input Wiring

3.3.3 +5 volt alarm signal

Figure 7 shows how an alarm signal that switches between +5 volts and ground is wired. If the alarm signal does not have a true ground level, terminal ‘B’ must be connected to ground.

3.3.4 Analog input (Advanced mode)

For analog signals, either of the wiring configurations shown in Figures 8 and 9 can be used. The connection shown in Figure 8 will provide additional filtering of the signal.
