Complete LAN Access to Your Remote Site

IP-based connectivity means the NetGuardian 216 can be installed anywhere your LAN goes. You can add alar monitoring visibility to anywhere in your network, without installing expensive dedicated circuits or relying on modem connections to transport essential data.

Multiple Protocol Support

The NetGuardian 216 reports alarms via DCP, DCPf, DCPx or DCP1 over UDP/IP or TCP/IP. This allows the

etGuardian 216 to report to any T/MonXM Alarm Management System over LAN. The NetGuardian 216 also comes equipped with a modem, which enables it to report to T/Mon over a standard phone line. Dial-up reporting can be configured for either normal or back-up modes by setting call options with T/NG216-Dialup, enabling you to prevent toll charges from nuisance alarms. Use the NetGuardian 216's dial-up reporting as an alternate path, so you can rest assure that alarms will be sent to T/Mon even if the LAN is down. You can also configure secondary phone number to dial out to T/Mon in the event the first number the NetGuardian 216 tries is unavailable.

Easy Installation and Configuration

The NetGuardian 216 mounts in any 19" or 23" rack and occupies only ½ rack unit of space. The standard

etGuardian 216 has rear-panel connectors for alarms, dial-up connections, relay outputs, and analog inputs.

Configuration settings can be entered through T/NG216-Dialup. Configuration information is saved to the

etGuardian's nonvolatile RAM (NVRAM), where it is secure even during power outages.

The NetGuardian's power connections are convenient screw lug barrier plugs. To connect the NetGuardian to a

ower source, follow these steps:

NOTE: Do not apply –48V Power to the NetGuardian 216 Dialup until all power Connections in Step 1

through Step 8 have been completed.

NOTE: Use proper lug terminations on all power and frame ground connections to the NetGuardian 216

Dialup power input terminal strips.

1. Make sure the fuse from the front panel of the NetGuardian is removed.

2. Get the screw lug barrier plug.

3. Make sure that the power supply to the unit is off.

4. Connect a –48 VDC line to the –48V terminal and a battery ground to the GND terminal of the screw lug.

Seat the barrier screws firmly, but be careful not to nick the bare wire.

Note: Observe polarity when connecting battery leads. If using the –48 VDC red/black cables supplied with the unit, connect the black lead to battery GND and the red lead to –BATT. Standard gauge is 20 AWG, but may vary

etween 18 to 24 AWG.

5. Push the plug firmly into its socket. Note that this connection is keyed and the plug must be properly aligned

within the socket.

6. Do not power the unit until all connections have been made.

7. With the NetGuardian fuse removed, turn on the supply voltage.

8. Connect the black common lead of a voltmeter to the GND terminal and the red lead to the –48V terminal.

The voltmeter should read between –43 and –53 VDC. If the reading is outside this range, check your power supply.

4.6.1 Preliminary Network Configuration

In order for the NetGuardian to become configurable over the LAN, the IP address of the NetGuardian must be in the same subnet or on the same hub as your computer or network. The NetGuardian has a default IP address of

192.168.1.100 and a default subnet mask of 255.255.0.0. Configuring the NetGuardian to be in the same subnet as your computer or network can be achieved in one of two ways:

1. The most commonly used method: by accessing the NetGuardian via the front panel craft port and changing the IP address and subnet mask of the NetGuardian to match those of your computer or network, or

2. By temporarily changing the IP address and subnet mask of your computer in order to coincide with the

etGuardian's default IP address and subnet mask — Once you are in the same subnet as the NetGuardian's default settings, you can access the NetGuardian and change it's IP address and subnet mask in order to coincide with your computer or network settings.

To temporarily adjust your computer's IP address and subnet mask to correspond to these settings, follow these steps:

1. Access and write down your computer's IP address and subnet mask.

2. Temporarily change your computer's IP address to 192.168.1.200 (In a Microsoft Windows setting, the IP

address and subnet mask settings are typically found in the Control Panels - Network - TCP/IP window).

3. Temporarily change your computer's subnet mask to 255.255.0.0. Note: You will be prompted to automatically reboot your computer to initiate the changes.

4. You can now access the NetGuardian using T/NG216-Dialup over LAN using the NetGuardian's factory default IP address, 192.168.1.100. Assign the NetGuardian an IP address and subnet mask on your network.

5. Change your computer's IP address and subnet mask back to their original settings.

Once the IP address and subnet mask of your computer coincide with the NetGuardian's, you can configure the

etGuardian via T/NG216-Dialup. After you have configured the NetGuardian with the appropriate information,

change your computer's IP address and subnet mask back to their original settings.

Note: Make sure that grounds have a common reference usually accomplished by tying grounds together.

The NetGuardian 216 supports up to 16 discrete alarm inputs. Discrete alarms are typically used to monitor door alarms, power outages, equipment failures, and other on/off conditions.

Discrete alarm points connected to the NetGuardian are single-lead signals referenced to ground. The B side of each alarm point is internally wired to ground, so either a single wire bringing a contact to ground or a dry closure

with the second lead connected to the B side will be sensed as an alarm signal — see Figure 4.11 for an alar

connection diagram. To reverse the alarm point polarity so an open contact triggers an alarm point see section 5.8 (Editor Alarms Tab) for more information.

Connect discrete alarms to the 50-pin connector on the back panel. See Figure 4.12 for alarm and analog pinout information. Note: Make sure that grounds have a common reference usually accomplished by tying grounds together.

See section 10.3 (Color Code and Pinout for Standard Amphenol Wire) for the typical color coding of pins.

4.7.2 Analog Alarms

The NetGuardian 216's two analog inputs measure ranges of voltage or current inputs and can be used to measure

attery voltage, charging current, temperature, or other continuously variable conditions. The measurement range

of the analog channels is –90 to +90 VDC or 4 to 20 mA. Note: Default configuration is voltage.

Connect analog inputs 1-2 to the 4-pin connector labeled "Analogs."

5.6.2 Configure Dialup Channel

The NetGuardian supports two Dial-up Modes: Normal and Back-up mode. In Normal mode, the Dial-up channel is used as a dedicated line where LAN connectivity is not available. In Back-up mode, you can also use the Dialup channel as an alternate path for reporting alarms to T/Mon if the LAN is down. Note: only points which are configured to Dial may initiate a dial-out attempt to T/Mon.

Standard POTS Line

Dialup Channel

Network

DCP, DCP1, DCPf, DCPx

Fig. 5.13. Typical setup

Normal mode

In Normal Mode, the NetGuardian will dial T/Mon anytime a reportable alarm occurs. The call delay timer is used if the initial call attempt does not get through to dynamically delay the time in between subsequent calls — see Figure 5.14 for example.

Back-up mode

In Backup Mode, you can set the NetGuardian to dial T/Mon after a certain period of time by setting the Call Delay Timer and the backup mode check box. If the call delay time expires without DCP communication from T/Mon, then a dial out to T/Mon will commence. If the NetGuardian is unable to reach T/Mon , then another call is scheduled by increasing the last call delay period by four. The maximum call delay time is twenty-four hours. I the alarm continues unacknowledged, then the NetGuardian will continue to dial T/Mon every twenty-four hours.

The dial-out call pending will cancel if T/Mon collects the alarm via DCP or if T/Mon calls in prior to the scheduled call. The call is also cancelled if the alarm is acked locally by pressing the NetGuardian's FPAN switch, located on the front panel.

Fig. 5.18. Configure analog alarm descriptions in Analog Alarms tab

Note: The Analog Alarms channel is enabled if you see your description and "Yes" under the Enabled column see Figure 5.18.

Each of the NetGuardian 216 analog channels must be individually configured to monitor external analog data. The Analog to Digital Converter (ADC) supports a range of -90 to +90 VDC. There are four alarm threshold

oints in ascending or descending order: major under, minor under, minor over, and major over.

You can choose the values for each of the thresholds on all channels. Activate analog monitoring by entering descriptions for the channels you are using.

5.10.1 Current Sequencing

The thresholds for your analogs must be set from Under to Over in either ascending or descending potential (or current) order. Thus, the settings of -46, -47, -53, and -54 corresponding respectively to major under, minor under, minor over and major over is valid.

The analog alarms are set to measure voltage by default, and the thresholds are reported as actual units. To change any one analog alarm to measure current, a circuit board jumper setting must be changed. Refer to section 4.7.2.1 (Jumper Options) for details on jumper locations and positions.

The analog threshold alarms can be entered in either ascending or descending order. This allows a low negative voltage to be provisioned as either an under or over alarm to match the application context. In either case, the analog value between the minor over and minor under returns an alarm clear condition.

Fig. 5.19.

Illustration of analog voltage/current changes to threshold alarm

Note: The descending configuration is useful for monitoring battery voltage. In the descending configuration, a 0 volt reading will alarm as a major under (MjU).

The jumper inserts a 250 ohm shunt resistor across the input to convert the sensors current output to volts. Use ohms law to find the voltage drop across the 250 ohm shunt resistor (multiply the current by the 250 ohms resistance). Please refer to the operation manual for your sensor to determine any other conversion factors. This will allow you to correctly set the thresholds for over and under conditions.
