MacurcoTM DVP-1200 Manual

REV – 2.0.1 [34-8708-4770-9] 9 | P a g e

Do not bundle sensor power or sensor signal connections with other AC power cables to prevent electrical interference. If other AC power connections must be bundled with the DVP-1200 sensor cables, the sensor connections should be made with two twisted pairs of the appropriate gauge, with an overall foil and braid shield. All shields should be terminated at the DVP-1200 end of the cable only.

The power connections to the MRS-485 and remote mounted sensors should be size 18 AWG (minimum) for short runs. Refer to Table 3 1 for recommended wire gauges. The power for the MRS-485 adapter is connected via a two-terminal screw type connector, 12 to 24 VAC or 12 to 24 VDC and no polarity.

The MRS-485 adapter output is wired in the standard 2W-Modbus circuit definition with selectable built-in terminating resistors at the ends of the RS-485 bus. It is recommended to always use twisted wires to reduce noise and allow for reliable data communication over greater distances. For best performance use shielded 3-conductor wire with one twisted pair providing a pair for signal (A & B), common (COM) and shield ground (SHD) connections. Use at least 3-conductor wire with one twisted pair providing a pair for signal (A & B) and common (COM) connections. The Macurco MRS-485 Modbus output is connected via a four-terminal screw type connector.

Running the Modbus cable adjacent to or in the same conduit with high voltage wires is not recommended as there may be interference from the high voltages near the bottom left corner of the panel.

3.2.4 Remote Sensor Connection

Remote sensors must be connected to the DVP-1200 at one of the three RS-485 connectors labeled “MRS-485 DETECTOR CONNECTION”.

3.2.4.1 MRS-485 Connection and Operation

The Macurco MRS-485 Adapter converts the Macurco 6-Series 4-20mA analog output to a digital output for use with the DVP1200 and other addressable network systems.

To install the MRS-485 on a Macurco 6-Series detector,

1. Remove the 4-20mA/Power plug from the Macurco 6-Series gas detector

2. Plug the MRS-485 adapter into the empty socket.

3. Install the provided MRS-485 screw.

Figure 3-5 – MRS-485 Exploded View

Power connections to Macurco sensors used with the DVP-1200 are polarity-insensitive (no polarity) since a bridge rectifier is connected to the power input terminals. All sensors used with the DVP-1200 panel employ screw clamp terminal blocks for power and signal connections. The polarity of the current loop connections is marked on the printed circuit board of the sensor.

The MRS-485 will monitor the 4-20 mA current output of the detector. At power up and during its warm-up period, the 6-Series detector will communicate its sensor type over the 4-20 current output using a custom protocol. The MRS-485 will automatically register each 6-Series detector as it is programmed with information about all the detectors to which it can be connected. The MRS-485 will use this information to determine the gas level sensed by the 6-Series detector by measuring the 4-20 mA currentloop output during normal operation of the detector.

When the LED is solid GREEN, the operation is normal, the MRS-485 knows the detector type, no errors are detected, and no MODBUS data are being received or transmitted over the RS-485 line.

When the LED is GREEN with random bursts of AMBER, the operation is normal, and data are being received or transmitted over the RS-485 line. The AMBER LED will come on anytime that there is data traffic.

NOTE: After complete system installation, verify all sensors (verify sensor address and sensor type) connected to the panel are detected by the panel and there is not any trouble indication for any of the connected detector.

3.2.4.2 Connection

The Macurco MRS-485 output is connected via a four-terminal screw type connector. The MRS-485 adapter is wired in the standard 2W-Modbus circuit definition with selectable built-in terminating resistors at the ends of the RS-485 bus. The power for the MRS-485 adapter is connected via a two-terminal screw type connector, 12 to 24 VAC or 12 to 24 VDC and no polarity.

NOTE: Running the Modbus cable adjacent to or in the same conduit with high voltage wires is not recommended as there may be interference from the high voltages.

Figure 3-6 – MRS-485 Wiring Diagram

3.2.4.3 Dip Switches and Addressing

Each MRS-485 (and the detector it is connected to) must be configured to a unique address. If there are 10 detectors on the serial line, then 10 unique addresses must be used, one for each detector. To set the address, use the eight DIP switch positions. For each unit choose the value from 1 to 192 (see chart) and set the eight switches to match the address. UP means ON or 1 and DOWN means OFF or 0. For example, to configure a unit as address “50”, set switches “2, 5, 6” (see Table 3-3) to ON or in the up position (01001100).

NOTE: If CX-6 is assigned address X and connected to DVP-1200, then address X is assigned to NO2 Sensor (Type: 2) and address X+1 is assigned to CO Sensor (Type: 1) by the panel.

3.2.4.4 Topology

An RS485-MODBUS configuration without repeater has one trunk cable, along which devices are connected, directly (daisy chaining) or by short derivation cables. The trunk cable, also named “Bus”, can be long. Its two ends must be connected on “Line” Terminations. (See Section 3.2.4.5 Line Termination – End of Line Resistor). The use of repeaters between several RS485MODBUS is also possible.

The DVP-1200 has three Modbus termination blocks that will accept two trunk cable connections allowing for two MODBUS communication lines. The Trunk cable must be wired in parallel from the panel to the end of line with no off shoots “T-tapping”.

3.2.4.5 Line Termination – End of Line Resistor

The MRS-485 and DVP-1200 are wired in the standard 2W-Modbus circuit definition with selectable built-in terminating resistors at the ends of the RS-485 bus. The MRS-485 and DVP-1200 provide integral termination for the end of line resistors (EOL). The terminations use a 4-pin connector with a jumper to select termination: The user selects no termination or one of the two Modbus line termination options. The MRS-485 and DVP-1200 have two-line termination options (100 Ohm and 120 Ohm) available.

Place the EOL jumper on one of the following positions:

N = No termination (default) 2 = 120 ohm 1 = 100 ohm

Figure 3-8 – EOL Jumper Settings

3.2.4.6 Baud Rate

At the baud rate of 19200 (default baud rate for Macurco MRS-485 and DVP-1200) and with cables less than 1,000 ft. in length, termination resistors are not recommended.

At the baud rate of 19200 and with cables longer than 1,000 ft., termination resistors are recommended.

It is recommended to use an RS-485 type of cable and 120 ohms for termination resistor.

An RS-485 network requires a 3-wire cable: a twisted pair and a third wire. It is difficult to tell whether shielding is required or not in a particular system until problems arise, so it is recommended to always use shielded cable.

When using termination resistors use only 2 resistors, one at each end of the RS-485 transmission line (i.e., 1 at the DVP-485B and 1 at the last/farthest MRS-485).

For any other baud rates calculate when (at what length) termination resistors are required. This is calculated by dividing the length L by the ratio between the new baud rate and 19200 or (x/19200) where x is the new baud rate.

MacurcoTM DVP-1200 Manual

REV – 2.0.1 [34-8708-4770-9] 17 | P a g e

3.2.4.7 Wire Selection

For best performance, use shielded 3-conductor wire with one twisted pair providing a pair for signal (A & B), common (COM) and shield ground (SHD) connections.

For the balanced pairs used in an RS485 system, wire with a characteristic impedance of higher than 100 Ohms may be preferred, especially for 19200 and higher baud rates.

3.2.4.8 Wire Length

For the RS485-MODBUS, the wire gauge must be chosen sufficiently wide to permit the maximum length (1000 m or 3281ft). 24 AWG is always enough for the MODBUS Data. The modular RS-485 connector will accept wire from 16 to 28 AWG. The wire insulator must be rated for at least 140°F (60°C). Category 5 cables may operate for RS485-MODBUS, to a maximum length of 600 m 1968.5 ft.

The maximum length of the trunk cable depends on the

• baud rate

• cable (gauge, capacitance, or characteristic impedance)

• number of loads on the daisy chain

• network configuration (2-wire)

For a maximum 9600 Baud Rate and 26 AWG (or wider) gauge, the maximum length is 1000m (3281ft). The derivations must be short, never more than 20m (65.5ft). If a multi-port tap is used with n derivations, each one must respect a maximum length of 40m (131ft) divided by n.

3.2.4.9 Grounding

The Common Circuit (COM) must be connected directly to protective ground, preferably at one point only for the entire bus. The shield should be connected to each detector at the SHD terminal and connected to a ground terminal or chassis only at one end of the bus.

3.2.4.10 External Power Supply

Select a UL Listed NEC Class 2 power supply which can power the MRS-485 units connected to 6-Series detectors.

To determine the required minimum power supply,

• Each MRS-485 connected with a detector is rated at 3.25W.

• The minimum power which the power supply needs to deliver for 12 detectors is figured as: 12 detectors x 3.25 W per

detector = 39W

• Therefore, a 24VDC, 60W power supply will work.

3.2.4.11 Power Wire

All field wiring is completed via modular connectors (provided). After wiring, simply plug the modular connectors into the matching connectors on the MRS-485. The power connections to the remotely mounted detectors should be size 18 AWG (minimum) for short runs. Since Macurco detectors are rated for operation between 12 and 24 VDC or VAC, the voltage drop between the power supply and the MRS-485 should not be an issue if the recommended power wire gauge guidelines are followed.

The terminals will accept wire from 16 to 28 AWG. To install a wire, strip back approximately 0.25 in. (6 mm) of insulation and insert the bare wire into the terminal. Tighten the screw clamp and ensure that the wire cannot be easily pulled from the connector.

Page 18

MacurcoTM DVP-1200 Manual

REV – 2.0.1 [34-8708-4770-9] 18 | P a g e

3.2.4.12 4-20mA Connection

There are three 4-20mA output modular connectors. The wire terminals for the three 4-20 mA connectors are available at the connector labeled “4-20mA O/P”. The connector accepts wires from 16 to 28 AWG. Refer to Figure 3-4 for details.

3.2.4.13 Relay Connection

The wire terminals for the four onboard relays are available at the connectors labeled “R1”, “R2”, “R3”, and “R4”. The wire

terminals for the optional expansion relays are available at the connectors labeled “R5”, “R6”, “R7”, and “R8”.

Each relay will be wired to be either normally open (NO) or normally closed (NC). There is no polarity for these connections. Each terminal can accommodate a wire size from 12 to 24 AWG.

Connect one wire to the COM terminal. For normally open (NO) configuration, connect the other wire to the NO terminal. For normally closed (NC) configuration, connect the other wire to the NC terminal.

To connect wires to the relay terminals,

1. Strip each wire back 1/4 in. (6.5 mm).

2. Press down the white button of the connector.

3. Insert the bare wire into the wire cavity of the connector.

4. Release the white button.

5. Ensure that the wire cannot be easily pulled from the connector.

3.2.5 Remote Device Connection

In addition to the onboard relays (four standard and four optional), the DVP-1200 can be connected to four additional Remote Devices. Each remote device can be configured with 4 expansion boards that include a combination of Expansion Relay Board: 2 SDPT, Expansion Analog Input Board: 4 Analog Inputs and Expansion Analog Output Board: 2 Analog Outputs.

The Remote Devices can be wired directly into the trunk cable of a new or existing Modbus communication line.

3.2.5.1 Remote Device (RD-24) Mounting

Macurco RD-24 is shipped with mounting screws, and the enclosure provides pre-determined mounting locations, with one screw in each corner. RD-24 should be mounted with sufficient space around the enclosure to allow for ease of opening enclosure door, as well as wiring access.

3.2.5.2 Remote Device (RD-24) Wiring

All the connectors in RD-24 are spring tightening and will accept wire from 14 to 24 AWG. To connect the wires to terminals, press down the white button of the connector (use flat-headed screwdriver), insert bare wire into respective wire cavity of the connector and release the white button. Ensure that the wire cannot be easily pulled from the connector. Refer to Figure 3-2 below for location of different connectors in RD-24. *The Analog Input board has 4 screw terminal connectors.

The power connections to the RD-24 should be size AWG18 (minimum) for short runs. For the longer run follow recommended power wire gauge guidelines. Match the polarity for power connection.

For RS-485 or communication connection it is recommended to always use a twisted wire to reduce noise and allow for reliable data communication over greater distances. For best performance use shielded 3-conductor wire with one twisted pair providing a pair for signal (A & B), common (COM) and shield ground (SHD) connection.

NOTE: Running the RS-485 cable adjacent to or in the same conduit with high voltage wires is not recommended as there may be interference from the high voltages.

RD-24 provides integral termination for end of line resistors (EOL). The termination uses a 4-pin connector (labeled J8) to select termination. Place the EOL jumper on one of the following positions:

• NU = No termination (default)

• 120 = 120 Ohm

• 100 = 100 Ohm

3.2.6 Remote Device Operation

Power LED will light up green to indicate the unit is operational. TX LED will flash blue to indicate the unit is communicating with DVP-1200. Slot 1,2,3,4 LED will light up green when corresponding expansion board is in use. Refer to Figure above for location of Slots 1 through 4.

3.2.6.1 Changing RD-24 Settings

The DIP switches are used to set the Modbus address and are also used to change the communication settings. Valid Modbus addresses for RD-24 are from 193 to 200 where switch 1 is the least significant bit (LSB) and switch 8 is the most significant bit (MSB). Address 254 is used to place the RD-24 in programming mode. Address 255 is used to refresh the configuration of the RD-24.

3.2.6.2 Programming Mode

When the RD-24 is powered with address set to 254, it enters programming mode. The STATUS LED will be flashing RED and GREEN alternatively every 200 milliseconds to indicate that RD-24 is ready and waiting for the user to enter new communication settings using 8 dip switches. Using the 8 dip switches, use can change the communication settings like baud rate and parity.

When looking at the switches with “Address” marking on top, the switches are defined from left to right.

• Switch 8, switch 7 and switch 6 are used to modify baud rate

• Switch 5 and switch 4 are used to modify parity

• Switch 1 is used to request to save the new settings

• Switches 3 and 2 are unused and should be left in the ON position.

3.2.6.3 Configuration Refresh

Upon initial installation, or when the user would like to change the RD-24 configuration (move, swap, or change expansion board type or locations), the following process must be followed. Before making any changes, power off the RD-24. Next, make the preferred changes to the RD-24 configuration. After, set the dip switch address to 255 and power on the RD-24 for at least 3 seconds. The LED below the dip switch should blink green rapidly. After at least 3 seconds, power off the RD-24. Using the dip switch, change the address back to its original setting, or a number between 193 and 200. Power on the RD-24. Last, navigate in the DVP-1200 menu CONFIGURE SYSTEM →MANUAL CONFIGURE →CONFIG. RLYS,SIGNALS,SENSORS,REM. DEV. →REMOTE DEVICES. Select the Remote Device and delete it from the DVP-1200. If the RD-24 is still powered on, the DVP-1200 will automatically find it, and update the configuration. If the DVP-1200 does not find the device after 60 seconds, power cycle the panel and check again.

3.2.7 Horn & Strobe Connection

There are four connection terminals for horns and strobes. The modular connectors are located at the top left of the board and are labeled “Horn/Strobe”.

Refer to Table 3 4 for recommended wire gauge vs. run length for the horn & strobe functions (maximum 2.5-volt drop in the wire). The horn & strobe circuits are Class 2 control circuits, so Class 2 conductors should be used.

If the sensor in the warning is assigned to any of the zones, then the status of the zone is updated to indicate WARNING in the middle box of the display.

The bottom box will cycle through all sensors that are in warning, at five seconds per display. It will display sensor address, gas type, zone number (if assigned to a zone) and corresponding gas reading.

If the buzzer and/or an external horn and/or external strobe are connected and configured to signal a warning condition, they will also sound when a warning condition occurs. There is a configurable delay before the horn or strobe will sound.

When the HUSH key is pressed, the internal buzzer will be silenced for fifteen (15) minutes. The HUSH key must be held for three (3) seconds to silence the horn and strobe.

When all indicators have been silenced, the display will show that warnings have been silenced for fifteen minutes. After any key is pressed (or five seconds) the display will return to normal mode and hush led will light up steady red.

4.4.3 Trouble Status Display

If a sensor fails, a connection is lost or the panel itself detects a failure of its own, the panel will enter TROUBLE mode during which the internal buzzer will sound, the POWER/TROUBLE LED will be red, and the display will switch to the trouble status display.

Figure 4-5 – Trouble Display Status

MacurcoTM DVP-1200 Manual

REV – 2.0.1 [34-8708-4770-9] 27 | P a g e

The top left box will have TROUBLE highlighted.

If the sensor in trouble is assigned to any of the zones, then the status of the zone is updated to indicate TROUBLE in the middle box of the display.

The bottom box will cycle through all sensors that are in trouble, at five seconds per display. It will display sensor address, gas type, zone number (if assigned to a zone) and corresponding trouble description.

Possible trouble conditions are:

• Any configured channel has less than 4 mA flowing in the current loop

• A sensor is reporting a trouble condition

• Any configured channel wiring is open or shorted.

• Internal controller board problems are detected.

If an external horn and/or strobe are connected and configured to signal a trouble condition, they will also sound when a trouble condition occurs, after a delay, if that configuration option is selected.

When the HUSH key is pressed, the internal buzzer will be silenced for eight (8) hours. HUSH key must be held for three (3) seconds to silence the horn and strobe.

When all indicators have been silenced, the display will show that trouble indications have been silenced for eight hours. After any key is pressed (or five seconds), the display will return to normal mode and the hush led will light up steady red.

4.4.4 Unoccupied Failure Display

When Title 24 is enabled, during unoccupied time, DVP-1200 compares the readings of all CO detectors connected (irrespective of assigned zones), and if any CO detector is more than 15 ppm above or below the average of all CO detectors for longer than 4 hours, the detector has failed. This failure is referred to as unoccupied failure in the rest of the manual. Refer to “Section 4.6.3.5 for process to define occupied time. Time outside the defined occupied time is unoccupied time.

If there is unoccupied sensor failure, the panel will enter ALARM mode during which the internal buzzer will sound, the ALARM/WARNING LED will be red, and the display will switch to the ALARM status display. Any outputs assigned to alarm condition will be triggered. Figure 4-6 shows an example of DVP-1200 display during unoccupied failure. “FAIL - UNOCC.” on the screen indicates unoccupied failure.

Figure 4-6 – Unoccupied Failure Display Status

DVP-1200 displays the address of the unoccupied failure detector. If there is more than one unoccupied failure detector, then display scrolls every 5 seconds to display all unoccupied failure detectors.

Page 28

MacurcoTM DVP-1200 Manual

REV – 2.0.1 [34-8708-4770-9] 28 | P a g e

If unoccupied failure sensor is part of a zone (Zone 2 in above figure), then the status of the zone will be updated to ALARM and all outputs assigned to that zone will get activated. If 4-20mA output is assigned to the zone with unoccupied failure sensor, then its output will be 20mA.

When the HUSH key is pressed and held for 5 seconds, the internal buzzer will be silenced for 4 hours. If the horn or strobe turn on delays have not finished, then they will also be silenced.

When all indicators have been silenced, the display will show that unoccupied failure indications have been silenced for four hours and the display will return to normal mode. In VIEW SENSOR screen, sensors with unoccupied failure silenced will display “FAILED UNOCCUPIED” alternating with current gas reading.

4.4.5 Occupied Failure Display

When Title 24 is enabled, during occupied time, DVP-1200 compares the readings of all CO detectors assigned to a zone, and if any CO detector is more than 15ppm above or below the 30-minute rolling average of all CO detectors assigned to the corresponding zone, then the detector has failed. This failure is referred to as occupied failure in the rest of the manual. Refer to “Section 4.6.3.5 for process to define occupied time.

If there is occupied sensor failure, the panel will enter ALARM mode during which the internal buzzer will sound, the ALARM/WARNING LED will be red, and the display will switch to the ALARM status display. Any outputs assigned to alarm condition will be triggered. Figure 4-7 shows an example of DVP-1200 display during unoccupied failure. “FAIL - OCC.” on the screen indicates occupied failure.

Figure 4-7 – Occupied Failure Display Status

DVP-1200 displays the address of the occupied failure detector. If there is more than one occupied failure detector, then display scrolls every 5 seconds to display all occupied failure detectors.

The status of the zone with occupied failure sensor will be updated to ALARM and all outputs assigned to that zone will be activated. If 4-20mA output is assigned to the zone with occupied failure sensor, then its output will be 20mA.

When the HUSH key is pressed and held for 5 seconds, the internal buzzer will be silenced for 5 minutes. If the horn or strobe turn on delays have not finished, then they will also be silenced.

When all indicators have been silenced, the display will show that occupied failure indications have been silenced for 5 minutes

and the display will return to normal mode. In VIEW SENSOR screen, sensors with occupied failure silenced will display “FAILED OCCUPIED” alternating with current gas reading.

4.4.6 Calibration Due Warning Display

When there are up to 30 days until calibration for any carbon monoxide sensors connected, panel will trigger Calibration Due Warning. Calibration Due Warning has lower priority than gas warning. This feature is applicable only for carbon monoxide detectors with calibration period feature with Title 24 feature enabled in DVP-1200.

DVP-1200 displays the address of the detector with calibration due warning. If there is more than one detector with calibration due warning, then display scrolls every 5 seconds to display all detectors with calibration due warning.

If there is a carbon monoxide sensor with calibration due warning, the panel will enter WARNING mode during which the internal buzzer will sound, the ALARM/WARNING LED will be amber, and the display will switch to the WARNING status display. Any outputs assigned to warning condition will be triggered.

Figure 4-8 – Calibration Due Warning Display Status

When the HUSH key is pressed and held for 5 seconds, the internal buzzer and horn/strobe will be silenced. Silence period is dependent on time left to calibration. The following table shows silence period for different time to calibration.

Time till Calibration

Silence Period

>14 days, and <30 days

14 days

>7 days, and <14 days

7 days

< 7 days

Table 4-2 – Calibration Due Silence Period

When all indicators have been silenced, the display will show that calibration due warning indication have been silenced for corresponding silence period. After approximately 5 seconds the display will return to normal mode. Only a calibration due warning with lower silence interval (refer Table 4-2) or calibration due warning from new sensor will reset the HUSH and panel will go back to state indicating Calibration Due Warning.

When in normal display mode, for detectors with Calibration Due Warning silenced, panel will display current gas reading alternating with “CALIBRATION DUE” in VIEW SENSOR screen for the corresponding sensor.

4.4.7 Calibration Overdue Trouble Display

When the panel detects a carbon monoxide sensor with Calibration Overdue condition it will go into trouble state. This trouble has higher priority than a regular trouble condition. This feature is applicable only for carbon monoxide detectors with calibration period feature with Title 24 featured enabled in DVP-1200.DVP-1200 displays the address of the detector with calibration overdue trouble. If there is more than one carbon monoxide sensor with calibration overdue condition or are sensors in trouble due to other conditions, then display scrolls every 5 seconds to display all detectors with the trouble condition.

Figure 4-9 – Calibration Overdue Display Status

During Calibration Overdue trouble, the trouble LED will be ON (the POWER/TROUBLE LED will be red), and the display will switch to the TROUBLE status display. Any outputs assigned to trouble condition will be triggered. The status of the zone with calibration overdue carbon monoxide sensor will be updated to TROUBLE and all outputs assigned to that zone will get activated. If 4-20mA output is assigned to the zone with calibration overdue sensor, then its output will be 20mA.

When the HUSH key is pressed and held for 5 seconds, the internal buzzer will be silenced for 15 minutes. If the horn or strobe turn on delays have not finished, then they will also be silenced for 15 minutes.

When all indicators have been silenced, the display will show that calibration overdue trouble indication have been silenced for 15 minutes. After approximately 5 seconds the display will return to normal mode.

When in normal display mode, for detectors with calibration overdue trouble silenced panel will display “CALIBRATION REQUIRED” in VIEW SENSOR screen for the corresponding sensor.

4.5 Ventilation Control

The ventilation control function operates independently from the alarm function. It provides the ability to configure the DVP1200 for control of up to 8 zones. Each zone can be configured to control relays and an external horn and strobe if desired.

When more than one zone is controlling a relay, it only takes one zone to activate the relay, but all controlling zones must release the relay before it turns off. Each of the relays, horn, and strobe has independent turn-on delays (to ignore short duration, transient gas signals) and turn off delays (to ensure minimum run times for fans that must run for internal cooling).

A VFD may be enabled and controlled by the DVP-1200 output relays or the DVP-1200 4-20mA output. This allows an operator to change fixed speeds for a VFD if it is used as a stand-alone control.

Here is an example of an application where VFD is controlling the speed of a fan: An operator can close relay 1, 2, or 3 to set the fan speed. If relay 1 is closed, the VFD will operate at 50%, If relay 2 is closed, the VFD will operate 75%, If relay 3 is closed, the VFD will operate at 100%.

Each zone can respond to gas levels indicated by one or more of the sensors, with configurable turn on and turn off concentrations (rising and falling) for each gas type.

For example, each zone can be configured to monitor a separate set of four sensors and control a single relay.

A single sensor may be assigned to multiple zones if desired. Here is an example of a control scheme which has single sensors assigned to multiple zones:

1. One zone monitors all sensors and turns one relay on at a low gas concentration.

2. A second zone monitors the same sensors and turns on a second relay if the gas concentration reaches a higher level.

3. A third zone also monitors the same sensors and turns on the last relay as a signaling device to a live monitor station,

as well as turning on an external horn and strobe.

In addition to controlling the relays based on the gas concentration, each zone can have a timed function, e.g., turn on low volume ventilation fans at 7:00 AM and turn them off at 8:00 PM.

The following options are available for GROUP CONFIGURATION:

• RISING – If the gas concentration is greater than or equal to this level, the zone output(s) will be turned on.

• FALLING – If the gas concentration is less than or equal to this level, the zone output(s) will be turned off.

• WARNING - The gas concentration used to trigger a warning status for the group of sensors within the zone. Setting a

warning level of 0 (zero) will disable warning detection for this sensor.

• ALARM – The gas concentration used to trigger an alarm status for the group of sensors within the zone. Setting an

alarm level of 0 (zero) will disable alarm detection for this sensor.

• MODE – When multiple sensors are being monitored by a group, the output decision can be based on either voting, or

the average of all sensors in the group. Valid modes are AVERAGE or VOTING (default). The bottom box in the LCD displays the current Mode used for the group (or sensor type).

o AVERAGE: The gas concentrations from all sensors (of same type) in the group in a zone are averaged and

▪ If the average is greater than or equal to the rising trip point, the zone outputs(s) are activated. ▪ If the average is less than or equal to the falling trip point, the zone output(s) are de-activated. ▪ If the average is between the two trip points, the outputs remain in their previous state.

o VOTING: The number of sensors (of same type) in the group indicating a value greater than or equal to the

rising trip point is counted.

▪ If the count is greater than or equal to the QUORUM, then the zone output(s) are activated. ▪ For zone outputs to be deactivated first the count of sensors (of same type) with value greater than

or equal to the rising trip point should be less than quorum value and count of sensors (of same type) with value less than or equal to the falling trip point should be greater than or equal to the quorum. NOTE: Activating the output(s) is given priority if there is an equal number of sensors (of same type) with gas readings greater than or equal to the rising trip point and sensors (of same type) with readings less than or equal to the falling trip point.

▪ QUORUM: It is up to the installer to ensure that the quorum entry is appropriate for the

configuration. A value greater than the number of sensors being monitored by the group stops the group from controlling the outputs. The default quorum value is 1. Select Quorum and hit Enter after Selecting Voting to change the quorum to values other than default value of 1.

Figure 4-30 – Zone 4-20mA Output Number Menu

NOTE: Oxygen sensor readings are an exclusion for 4-20mA output i.e., its reading is not considered while computing output value for 4-20mA output.

Next, the output mode can be set to PEAK or SCALE.

PEAK – In this mode the gas reading active in the zone (except for the oxygen) corresponding to highest mA output is used to control the analog output assigned to the specific zone. In this case, any active gas reading, that is part of the zone will be taken in consideration, and the sensor reading corresponding to highest mA output will be used to control the analog output. E.g. If a CO and NO2 sensor is assigned to a zone and CO Sensor reading is 50ppm (which corresponds to 8mA) and NO2 sensor reading is 10.0ppm (which corresponds to 12mA) then 4-20mA or Analog output assigned to the zone will output 12mA.

SCALE – In this mode, the 4-20mA value for all detectors added to a zone are computed (for all sensor types except oxygen), and the output is the average of the 4-20mA value for all detectors assigned to the zone. E.g. If a CO and NO2 sensor is assigned to a zone and CO Sensor reading is 50ppm (which corresponds to 8mA) and NO2 sensor reading is 10.0ppm (which corresponds to 12mA) then 4-20mA or Analog output assigned to the zone will output 10mA.

To select the output mode for 4-20mA output, select OUTPUT MODE from the 4-20 O/P menu and press ENTER. Then, select PEAK or SCALE from the 4-20 O/P MODE menu and press ENTER. The display will return to the 4-20 O/P menu and the output mode selection will be updated as shown in Figure 4-31.

When the status of the zone is TROUBLE then 4-20mA output assigned to corresponding zone will switch the output to 20mA.

This option allows the user to disconnect a sensor for repair or replacement without any trouble or error on the panel. For example, to replace a sensor, first disable that specific sensor in the panel. Then, disconnect it from the system and replace it with the new unit (of same type). Lastly, return to the VIEW SENSORS menu and enable the sensor. Using this method, all previous sensor configurations will be retained so it will not be necessary to reconfigure the sensor.

Delete – This will delete the sensor from the panel and from all the zone to which the sensor is added.

If the sensor is connected to the panel even after deleting it, then the panel must discover the sensor again. However, it will be like a new sensor discovery. Therefore, the sensor will not be added to any zones.

Note: When replacing a sensor (already registered with DVP-1200) with a sensor of different type but same address (e.g. CO sensor with address 17 replaced with NO2 sensor with address 17) then it is recommended to perform a Delete operation for corresponding sensor address, after sensor replacement is complete, and verify correct sensor type is displayed for corresponding sensor address.

5 BACnet

5.1 General Information

When DVP-1200 boots, it is set by default to acquire the IP address using the DHCP client. For the BACnet the following information is important and will be necessary to configure the BACnet/IP client.

Note: For the DVP-1200N Model, the ethernet port is not included and BACnet output is not an option

Note:

• Device Instance: 12345 (default)

• Port Number: 47808

• IP Address: Use the IP address being leased by the DHCP server (router). This information can be retrieved by checking

ETHERNET SETTING in COMMUNICATION setting of the DVP-1200 connected to the network on the DHCP server. If static IP address is being used, use the one that was assigned to the DVP-1200.

• DVP-1200 BACnet/IP interface server, only allows the client to read values from DVP-1200. Writing is not allowed by

the interface.

The following information about DVP-1200 is accessible via BACnet.

1. Group Settings (Range, Alarm, Warning, Rising, Falling) for Each Sensor and Each Zone

2. Readings and Type for All Detectors

3. Zone Configurations (Types of detectors assigned, Horn/Strobe Assigned, Relay Assigned, Analog Output Assigned,

Quorum for Voting Mode)

4. Output Status and Values of DVP-1200 Outputs

5. Title 24 Configuration and Sensor Status

6. Remote Devices Status and Configuration

7. System Status and Fault Events

8. Warning and Alarm Settings for Sensors Not in a Zone

Note: BACnet Objects with value 65535 indicate the value received is not reliable. Some of the possible reasons for such a high value received are sensor not connected to panel, sensor is in trouble, or invalid/not supported BACnet object. Operators must figure out the root cause of such readings.

For details on BACnet implementation or BACnet capabilities of DVP-1200, refer to DVP-1200 PICS available on the product page on the company website (www.macurco.com).

5.1.1 Group Settings for Each Sensor and Each Zone

Information about Group Settings for each gas type can be accessed via BACnet output in DVP-1200. Table 5-3 shows the BACnet Object Type and Object Instance for each object. N in Table 5-3 refers to zone number. E.g., if I want to access the Alarm settings for CO sensor in Zone 3, then Object Instance for the corresponding object is 3+ (3-1) * 68= 139.

Group settings are local to zone and hence each zone can have different settings for same type of sensor. Table 5-1 shows

the possible values for ‘code’ object and corresponding detector type. Similarly, Table 5-2 shows the possible values for ‘Eng. Unit’ object and corresponding engineering unit.

5.1.2 Readings and Type for All Dectectors

Each sensor addresses from 1 to 192 has two BACnet Objects (one for sensor reading and one for sensor type referred as group). Table 5-4 shows the BACnet objects and corresponding object instance. N in Table 4 refers to the sensor address. E.g., to retrieve sensor reading for address 16, corresponding object instance is 553 + (16-1)*2 = 583.

If a sensor address is not detected by the panel, then corresponding BACnet object reading and group value will be 65535 and 0, respectively.

Note: If the value of sensor reading BACnet object is outside the range of detection of the sensor then the reading is not reliable and cause for unreliable reading must be investigated. Refer to Table 4-2 or sensor manual for information on range of detection.

Table 5-4 – BACnet Object for Detector Reading

5.1.3 Zone Configurations

(Types of detectors assigned, Horn/Strobe Assigned, Relay Assigned, Analog Output Assigned, Quorum for Voting Mode) for all Zones

Table 5-6 shows the BACnet Objects representing zone configuration for each zone. N in Table 5-6 refers to Zone number.

When binary output is set to 1 (or active), it means that the corresponding DVP-1200 output (Horn/Strobe, Relay) is configured or assigned to that zone, or in case of the group[X] means that the sensor of type X (Table 5-1 lists the valid values of type i.e., value of X) is added to that zone.

If any of the three analog outputs are assigned to the zone, then object “analog output” for corresponding zone will have

the analog output number (valid values are 1,2 and 3). If the zone does not have any analog (or 4-20mA) output assigned,

then “analog output” will have value 0.

“mode” BACnet object retrieves information about the mode for each sensor type in the zone. Value for mode is a 12-bit

number. Bit 11, bit 10, and bit 6 are always set to 1. So, this field will have values from 3136 to 4095. If a sensor type has

mode set to ‘VOTING’ in Group Configuration of the Zone, then its corresponding bit will be set to 1. And, if the sensor type has mode set to ‘AVERAGE’ then its corresponding bit will be set to 0. E.g., If Zone [1]. mode present value is 4095 then it

means that all sensor types in Zone 1 are set to VOTING. Similarly, if Zone [2]. mode present value is 4094 then it indicates that all sensor types in Zone 2 are set to VOTING mode except Type 1 (CO) which is set to AVERAGE mode.

“Quorum[X]” is another analog type of object for Zone Configuration. If voting mode of operation for a sensor type X (Table 5-1 lists the valid values of type i.e., value of X) is selected, then value of this BACnet object represents quorum value for that sensor type.

5.1.4 Output Status and Values of DVP-1200 Outputs

When the output (buzzer, Horn/Strobe, Relay) is active the binary output value for corresponding output is set to 1 (active) and when the output is not active then the corresponding output is set to 0 (inactive).

For three analog outputs, the values of corresponding BACnet object represents the current output (in mA) from the analog or 4-20mA output in DVP-1200.
