1General Safety Information
1.1 List of warnings
WARNING
Each person using this equipment must read and understand the information in this
User manual before use. Use of this equipment by untrained or unqualified persons or
use that is not in accordance with this user manual, may
adversely affect product
performance.
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 pre
sent and could result in
overexposure. For proper use, see supervisor or User manual, or call Macurco Technical
Support at 1-844-325-3050.
DVP-120C may not function effectively below 32°F (0°C) or above 120°F (49°C). Using
the equipment outside of this temperature range may adversely affect product.
High voltage terminals (120/240 VAC) are located within the DVP-120C, presenting a
hazard to service technicians. Only qualified technicians should open the DVP-120C case
and service the internal circuits. Ensure power is removed from the DVP-120C prior to
servicing the unit.
Immediately exit any environment that causes an alarm condition on the sensor.
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 and
contact Technical Support at 1-844-325-3050.
Do not cover or obstruct audible alarm opening or visual alarm LED. Doing so may
adversely affect product performance.
Use only for monitoring the gases which the sensors and equipment are designed to
detect. Failure to do so may result in exposures to gases not detectable and result in
serious injury or death. For p
roper use, see supervisor or User manual, or Contact
Technical Support at 1-844-325-3050.
Failure to follow instructions outlined in this user manual can result in sickness or death.

2Use Instructions and Limitations
2.1 DVP-120C General Description
The DVP-120C is an exhaust fan controller and alarm interface. When used in conjunction with Macurco gas
detectors, it provides automatic controls to help maintain an acceptable environment in enclosed facilities. The DVP-
120C is frequently used in parking garages, warehouses, and vehicle maintenance facilities. The DVP-120C system is
designed to meet specifications for safety in enclosed parking garages, including the Uniform Building Code and
OSHA 50ppm CO requirements. The standard DVP-120C can control up to 99 digital addressable sensors and is
compatible with Macurco CM-6 and TX-6-ND detectors ONLY. The DVP-120C is ready for operation after the wiring is
complete and the user system configuration is entered.
2.2 DVP-485B Modbus® Adapter
The DVP-485B Modbus adapter, installed in DVP-120C, provides a RS-485 BACnet output. System wiring includes RS-
485 serial detector interface as well as main power connection for the DVP-120C, the fan control and alarm
connections from the DVP-120C to the building ventilation and automation systems. The RS-485 serial interface is
from the DVP-120C to the remote detectors. Power to these detectors is provided by an external 24VAC or VDC low
voltage power supply. See section 3.2.3 Remote Sensor Connection for more information regarding remote power
supplies.
2.3 MRS-485 Modbus 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-120C 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 mounts to a Macurco 6-
Series detector installed on a 4”x 4” electrical box electrical box supplied by the contractor.
WARNING
Each person using this equipment must read and understand the information in this
User manual before use. Use of this equipment by untrained or unqualified persons or
use that is not in accordance with this user manua
l, may adversely affect product
performance.

3Installation Instructions
Gas detection and exhaust fan control are provided by a Macurco DVP-120C system. System wiring includes the
main power connection for the DVP-120C, the fan control connections and/or alarm connections from the DVP-120C
to the building ventilation and automation systems. The DVP-120C also includes the RS-485 serial interface from the
DVP-120C to the MRS-485 and remote detectors. Power to the MRS-485 and detectors is provided by
isolated/remote low voltage power supply.
The system is configured by the user through the LCD display and keypad. The system display provides the user with
the system status and the status of each configured sensor. In addition, all control functions of the DVP-120C may be
accessed through the system display and keypad.
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. For proper use, see supervisor or User manual, or call Macurco Technical
Service at 1-844-325-3050.
This DVP-120C system should be used with Macurco™ CM-6 and TX-6-ND transducers and each unit will measure
the level of the target gas (i.e. CO, and NO2) and provide this information to the DVP-120C over Modbus
communication loop. The transducers operate on low voltage (24VDC). All power and signal connections for the
transducers are provided via unshielded two conductor cable from an external power source. DVP-120C 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-120C 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-120C 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.
3.1 Location & Mounting
The DVP-120C should be installed in a centralized location, easy to access and protected weather and other
environmental elements. DVP-120C is intended for indoor use only. A Mechanical room, Alarm Control Room or
other similar areas are recommended.
Mounting holes are provided in the DVP-120C 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 3-1. The panel should be
mounted with sufficient space around the panel for access to conduit entry holes provided on the top, bottom and
right side of the panel.
