1. Introduction
1.1 General Information
The DVP-120 exhaust fan controller, in conjunction with Macurco™ gas transducers, provides automatic controls to help maintain an
acceptable environment in parking garages or other facilities. The DVP-120 system is designed to meet specifications for safety in
enclosed parking garages, including the Uniform Building Code and OSHA 50ppm CO requirements. The DVP-120 can control up to
twelve gas sensors in any combination (i.e. CO, NO2, EX). The DVP-120 is ready for operation after the wiring is complete and the
user system configuration is entered.
1.2 DVP-120M Addressable Detection and Ventilation Control Panel
The DVP-120M is a Modbus-Enabled Detection and Ventilation Panel with up to 87 Modbus addressable sensors on three channels of
29 sensors per channel, plus the original 12 analog 4-20mA sensor channels. The DVP-485 Modbus adapter increases the capacity of
the DVP-120 from 12 detectors to 99. System wiring includes 4-20mA current loop and RS-485 serial interface. System wiring includes
main power connection for the DVP-120M, the fan control and alarm connections from the DVP-120M to the building ventilation and
automation systems. The RS-485 serial interface is from the DVP-120M to the remote detectors. Power to the detectors is provided by
isolated/remote low voltage power supply.
1.3 Macurco MRS-485 Adapter
The Macurco MRS-485 adapter is an accessory used to convert the 4-20mA analog signal from Macurco 6-Series type detectors to a
digital signal for use with the DVP-120M and other multipoint addressable systems. The Macurco MRS-485 simply plugs into the back
of the detector and a single screw fastens it in place. The MRS-485 accepts the 4-20mA output and is powered from the same
connection as the detector. The MRS-485 is not intended for use in hazardous locations or industrial applications such as refineries,
chemical plants, etc. Do not mount the MRS-485 where the normal ambient temperature is below 0°F or exceeds 125°F (-18°C or
above 52°C). The MRS-485 mounts to a Macurco 6-Series detector installed on a 4” x 4” electrical box electrical box supplied by the
contractor.

! WARNING
This equipment helps monitor for the presence and concentration level of certain specified airborne gases. Misuse may produce an inaccurate
reading, which means that higher levels of the gas being monitored may be present and could result in overexposure and result in sickness or
death. For proper use, see supervisor or User Instructions, or call Macurco Technical Service.
This DVP-120 system should be used with Macurco™ transducers and each unit will measure the level of the target gas (i.e. CO, NO2,
EX) and provide this information to the DVP-120 over a 4-20mA current loop. The transducers operate on low voltage (24VDC). All
power and signal connections for the transducers are provided from the DVP-120 control panel, via unshielded four conductor cable.
For DVP-120M Modbus applications use shielded 3-conductor wire with one twisted pair providing a pair for signal (A & B), common
(COM) and shield ground (SHD) connections. The DVP-120 control panel provides three relays which can be used for ventilation fan
control or alarm signaling. These relays (SPDT - Form C) are for pilot duty only, capable of switching 10 amp loads up to 240 VAC.
Main power wiring should conform to national and local electrical codes, and may require separate inspections and certification.
Contact your local building authority for further details.
! WARNING
DVP-120 may not function effectively below 32°F (0°C) or above 104°F (40°C). Using the equipment outside of this temperature range may
adversely affect product performance and result in sickness or death.
2.1 Mounting the DVP-120
Mounting holes are provided in the DVP-120 case at the four corners. The top two are keyhole shaped so that the panel can be hung
and then the two bottom screws driven to hold the panel. See figure 2-1. The panel should be mounted with sufficient space all around
for access to Conduit entry holes provided on the top, bottom and right side of the panel.
Figure 2-1 Mounting holes
Typical coverage for CO, CO2 and NO2 sensors is 5,000 sq. ft. (464.5 sq. m), 900 sq. ft. (83.6 sq. m) for combustibles and other
toxic gases (see the User Instructions of each sensor type for location and coverage details). Extra sensors may be needed near
areas where people work, such as toll booths. Macurco provides only the control panels and sensors. Fans, relays, and other
devices are provided by the contractor. See the appropriate building code for the size of fans and air changes per unit of time.

2.2 General Wiring Information
! WARNING
High voltage terminals (120/240 VAC) are located within the DVP-120, presenting a hazard to service technicians. Only qualified technicians should
open the DVP-120 case and service the internal circuits. Ensure power is removed from the DVP-120 prior to servicing the unit.
With the exception of the safety ground, all field wiring is completed via modular connectors (provided). After wiring, simply plug the
modular connectors into the matching connectors on the printed circuit board (PCB).
DVP-120
The power and signal connections to the remote mounted sensors should be size AWG18 (minimum) for short runs. Refer to Table 2-2
for recommended wire gauges. Four conductor cables may be used in all cases since the DVP-120 employs DC power for remote
sensors to help prevent electrical noise from interfering with the sensor output signal.
Do not bundle sensor power and/or signal connections with other AC power cables to prevent electrical interference. If other AC power
connections must be bundled with the DVP-120 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-120 end of the cable only. A
ground stud is provided near the bottom left corner of the panel.
DVP-120M
The power connections to the remote mounted sensors and MRS-485 should be size AWG18 (minimum) for short runs. Refer to Table
2-2 for recommended wire gauges. 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. 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.
2.3 Main Power Connection
The main power cable should be routed into the bottom left conduit entry. Macurco recommends a minimum wire size of AWG18 and
the wire insulator must be rated for 140F (60C) service. The modular connector will accept wire from 12 to 24 AWG. The safety
ground wire should be secured to the ground stud at the bottom left of the cabinet with the lock washer and nut supplied. Use a ring
terminal for the ground connection. Refer to Table 2-1 for DVP-120 power connections. The line and neutral wires should be stripped
1/4 in. (6.5 mm), insert the wire into the wire cavity of the modular connector and tighten the screw clamp. Ensure that the wire cannot
be easily pulled from the connector. Plug the modular connector into AC~ on the PCB and ensure that it latches into the header
properly.

2.4 Remote Sensor Connection
Figure 2-3 System Wiring Diagram
DVP-120
Each remote sensor is connected by a four-wire connection – two wires for DC power and two wires for the 4 – 20 mA loop connection.
Be sure that the 4-20mA output on each sensor is set to “On”. The sensors are connected to the control panel PCB with modular
connectors, two sensors per connector. See Figure 2-5 for a view of a typical sensor connector. Refer to Table 2-2 for wire size
recommendations.

Figure 2-5 Sensor Interface Connector – Channels 5 and 6
Each 8-terminal sensor modular connector may be disconnected from the PCB connector to ease wire installation. 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. Connector to sensor C1

Table 2-2 Recommended Wire Gauge
DVP-120M
A MODBUS over Serial Line Cable should be shielded for best performance. The shield should be connected on each detector at SHD
terminal and connected to a ground terminal or chassis only at one end of the bus. An RS485-MODBUS must use a balanced pair (for
A-B) and a third wire (for the Common). For RS485-MODBUS, Wire Gauge must be chosen sufficiently wide to permit the maximum
length (1000 m or 3281ft). AWG 24 is always sufficient for the MODBUS Data. Category 5 cables may operate for RS485-MODBUS, to
a maximum length of 600 m 1968.5 ft. 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.
Note: It is recommended to always use twisted wires to reduce noise and allow for reliable data communication over greater distances.
Use at least 3-conductor wire with one twisted pair providing a pair for signal (A & B) and common (COM) connections.
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.

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 Line Termination - End of Line Resistor section). The use of repeaters between several RS485-MODBUS is also possible.
Length
The end to end length of the trunk cable must be limited. The maximum length depends on the baud rate, the cable (Gauge,
Capacitance or Characteristic Impedance), the number of loads on the daisy chain, and the network configuration (2-wire). For a
maximum 9600 Baud Rate and AWG26 (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.
Grounding
The Common circuit (COM) must be connected directly to protective ground, preferably at one point only for the entire bus.
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 remote mounted detectors should be size AWG18 (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 below 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.

2.5 Relay Connection
All poles of the three relays are available at the modular connector R1 R2 R3 (see Figure 2- for details). R1 R2 R3 is a 9-position
variant of the high voltage modular connector used for power input. Each terminal can accommodate a wire size 12 to 24 AWG.
Figure 2-6 Relay Connector

To install the wiring for the relays, disconnect the connector from the header on the PCB. Strip the insulation of each wire back
approximately 1/4 in. (6.5 mm), insert the bare wire into the terminal and tighten the screw clamp. Ensure that the wire cannot easily be
pulled from the connector.
2.6 Horn & Strobe Connection
The external horn and strobe connections are available at the modular connector S H (see Figure 2- for details). S H as a 4-position
connector, similar to the sensor interface connectors.
Figure 2-7 Horn & Strobe Connector
To install the wiring for the horn or strobe, disconnect the connector from the header on the PCB. Strip the insulation of each wire back
approximately 0.25 in. (6 mm), insert the bare wire into the terminal and tighten the screw clamp. Ensure that the wire cannot easily be
pulled from the connector. When all wires are connected, seat the modular connector into the PCB header; ensure that the latch
engages. Refer to Table 2-3 for recommended wire gauge vs. run length for the horn & strobe functions (maximum 2.5 volt drop in the
wire). The Strobe and Horn circuits are Class 2 control circuits so Class 2 conductors should be used.

! WARNING
Immediately exit any environment that causes an alarm condition on the sensor. Failure to do so may result in sickness or death.
2.7 Interfacing Macurco Sensors
DVP-120
Macurco sensors with current loop outputs may be used with the DVP-120. See macurco.com for information on compatible Macurco
gas transducers.
Power connections to Macurco sensors used with the DVP-120 are polarity-insensitive (no polarity), since a bridge rectifier is
connected to the power input terminals. All sensors used with the DVP-120 panel employ screw clamp terminal blocks for power and
signal connections. Polarity of the current loop connections is marked on the printed circuit board of the sensor.
See specific information on other manufacturer’s transducers.
11
DVP-120M
The Macurco MRS-485 Adapter converts the Macurco 6-Series 4-20mA analog output to a digital output for use with the DVP-120M
and other addressable network systems
1. Remove the 4-20mA/Power plug from the Macurco 6-Serires gas detector
2. Plug the MRS-485 adapter into the empty socket.
3. Install the provided MRS-485 screw.
4. See the wiring diagram for wire connection.
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.
DIP Switches and Addressing
Each MRS-485 (and the partner gas detector) 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 247 (see chart) and set the eight switches to match the address. UP means ON or 1 and DOWN means OFF or 0.
12
For example, to configure a unit as address “50”, set switches “2, 5, 6” (see table) to ON or in the up position (01001100). See page 11
for a list of applicable addresses and dip-switch settings.
Line Termination - End of Line Resistor
The MRS-485 adapter is wired in the standard 2W-Modbus circuits definition with selectable built-in terminating resistors at the ends of
the RS-485 bus. The MRS-485 provides integral termination for end of line resistors (EOL). The MRS-485 termination uses 4-pin
connector with jumper to select termination: The user selects no termination or one of the two Modbus line termination options. The
MRS485 has two line termination options provided onboard that should cover most situations.
Place the EOL jumper on one of the following positions:
1 = 100 ohm
2 = 120 ohm
N = No termination (default)
Normal Operation
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 6Series 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 current-loop output during normal
operation of the detector.
1. When the LED is solid GREEN, 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.
2. When the LED is GREEN with random bursts of AMBER, operation is normal and now data are being received or transmitted over
the RS-485 line. The AMBER LED will come on anytime that there is data traffic.

3.1 Initial Operating Mode
When power is first applied to the DVP-120, a few simple self-tests will be performed, and the system will cycle through all status lights,
and display the system name and model # (Figure 3-1). The system will then proceed to normal mode, if the operating parameters
have been entered.

! WARNING
Each time the unit is turned on it performs a self-test, which activates the audible and visual alarms. If the self-test fails, or all the alarms do not
activate, do not use. Failure to do so may adversely affect product performance and result in sickness or death.
If the user has not entered any parameters, the system WILL NOT be controlling the ventilation system. The relays WILL NOT actuate
and the horn and strobe outputs WILL NOT be powered. The power status light will show NORMAL (steady green) and the system will
immediately enter the CONFIGURATION mode, see section 3.2 for details to set the configuration parameters.
If a valid set of configuration parameters have been entered, the panel will wait for all sensors to warm up. During this time, the display
will show a count-down, minutes and seconds, until the end of the warm-up period, (Figure 3-2).

During the warm-up period, the keypad will be locked. When the warm-up period ends, the LCD will start showing the normal display.
3.1.1 Status Light Display
The POWER, ALARM/WARNING, SILENCE, RELAY 1, RELAY 2 and RELAY 3 status lights indicate the system status and provide
the following data:
POWER
Green (steady) – Power is good and there are no trouble indications
Yellow (steady) – Trouble is indicated by a transducer or the panel itself
ALARM/WARNING
Off – All indicated gas levels are below the warning level
Red (steady) – One or more gas levels is at or above the alarm level
Amber (steady) – One or more gas levels is at or above the warning level
HUSH
Off –There are no silenced alarms or warnings
Red (flashing) –There are alarms, warnings and/or troubles that have been silenced (gas levels may or may not
remain or continue to be at alarm or warning levels)
RELAY 1
Off – Relay 1 is not on
Green (steady) – Relay 1 is on
