Operations Overview 1-1 1. 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. Read this chapter carefully before proceeding with the installation and programming of the Cv2. For more details on configuring the operation through the programming software, refer to Chapter 3, Configuration. 1.1 Cv2 Capabilities When an alarm occurs, the Cv2 places a call

Operations Overview 1-2 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 “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 alar

Operations Overview 1-3 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

Operations Overview 1-4 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 res

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

Operations Overview 1-6 1.9 Indicators The Cv2 has four LED indicators to show the operation of the unit and assist in troubleshooting. When the Cv2 is initially powered up, the four LEDs will do the following: All will turn on for approximately one second. Hook will flash on and off for one second then go out. Tone will flash on and off for one second then go out. Voice will flash on and off for one second then go out. Alarm will flash on and off for one second then go out. Hook On

Operations Overview 1-7 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

Installation 2-1 2 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 flash memory. 2.1 Antenna requirements The antenna used for your installation will depend on the proximity of the alarm unit to the cellular carrier facility. If the installation is very close t

Installation 2-2 2.2.2 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 o does not go below -20 C o or above +50 C. Connect a DC power source to the terminals on TB2. The Cv2 requires up to 1.5 Amps to operate; the supply should be sized accordingly. Input power to the unit is protected by a Polyswitch current limiter. If

Installation 2-3 2.3.2 +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 5. 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 5 +12 Volt Input Wiring 2.3.3 +5 volt alarm signal Figure 6 shows how an alarm signal that switches b

Installation 2-4 2.4 Output port connections The output ports are open collector drivers that can sink up to 500 mA through a load connected to a voltage of up to +50 VDC. If an inductive load Figure 9 Output Wiring such as a relay is connected to an output, install a protective reverse-biased diode across the load to prevent damage to the output from the inductive flyback voltage. Figure 9 shows the connection for an output used as a relay driver. 2.5 Configuration programming connection W

Configuration using the PC 3-1 3 Configuration using the PC This chapter describes how to install the programming software and configure the operation of the Cv2. When the configuration is complete, it can be viewed through the Summary command found on the File pull-down menu. In the summary, Warnings should be checked to ensure that there are no improper settings in the configuration before it is transferred to the Cv2. 3.1 PC requirements The minimum requirements for the PC used to run the C

Configuration using the PC 3-3 3.4.6 Directories When an alarm is detected, the Cv2 will perform a specific sequence of events determined by the entries in the directory. Six directories are available, providing different actions for different groups. 3.4.7 Programming The programming section is used to transfer the configuration database between the PC and the Cv2. Recorded voices can also be transferred from the Cv2 and then back. 3.5 Configuring the Cv2 When configuring the Cv2, the sequenc

Default Debounce time: 0.05 sec A Digital input port can also be used to perform special functions in the Cv2. In the Groups section, it can be selected for the Local Acknowledge function, and in the Hardware section it can be set to operate as a Reset Input for a Totalizer.

Configuration using the PC 3-5 Analog Input Setting the input port type to Analog allows measurement of voltages between 0 and +5 volts. As with the other input types, the definition of an analog input is completed in the Points section where the range, setpoints and units are assigned. An Analog port can be changed to one of the other input types by selecting from the Change Input Port drop-down list. Changing input type will force any variables used in the Hardware section to the

Configuration using the PC 3-6 Each point can be placed into one of the six groups. If a port is used for one of the special functions, the Group section sets the ports. To access a point for configuration, select the Points button to bring up the summary of the settings. Status of the 30 points will be shown along with a brief description of their settings. Highlight the point to be edited, then select it by pressing Enter, double-clicking on the line, or choosing the Edit Line function from
