Page 5: Introduction
1 INTRODUCTION 1.1 General Information The DVP-120 Gas Detection and Ventilation Control Panel is a microcomputer based control panel used to operate ventilation fans based on the inputs from remotely mounted gas transducers. The unit is fully tested prior to leaving the factory, and is ready for operation after the wiring is complete and the user system configuration is entered. -
Page 6: Figure 1-1 System Wiring Diagram
Extra sensors may be needed near areas where people work, such as toll booths. 2. Macurco provides only the control panels and sensors. Fans, relays, and other devices are provided by the contractor. 3. See the appropriate building code for the size of fans and air changes per unit of time. -

ARE LIMITED TO A PERIOD OF TWO (2) YEARS FROM THE PURCHASE DATE. Macurco shall not be liable for any incidental or consequential damages for breach of this or any other warranty express or implied, arising out of or related to the use of the control panel. Manufacturer or its agent’s liability shall be limited to replacement or repair as set forth above. -
Page 9: Installation & Connection
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. Conduit entry holes are provided on the top, bottom and right side of the panel. -
Page 10: Main Power Connection
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. 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. -
Page 11: Table 2-3 Connector To Sensor Channel Mapping
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. -
Page 12: Relay Connection
2.5 Relay Connection All poles of the three relays are available at the modular connector J2 (see Figure 2-2 for details). J2 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. -
Page 13: Horn & Strobe Connection
2.6 Horn & Strobe Connection The external horn and strobe connections are available at the modular connector J5 (see Figure 2-3 for details). J5 as a 4-position connector, similar to the sensor interface connectors. 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. -
Page 14: Interfacing Macurco Sensors
2.7 Interfacing Macurco Sensors All Macurco CO, NO2 and combustible gas sensors with current loop outputs may be used with the DVP-120. Data sheets for the Macurco sensors listed in Table 2-8 are provided as an appendix to this manual. -
Page 15: Operation
3.1 Initial Operating Mode When power is first applied to the DVP-120, a few simple tests will be performed, e.g. 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. -
Page 16: User Interface
The keypad (Figure 3-3) is used to select the information displayed and to enter the configuration parameters, which are stored in the DVP-120 non-volatile memory. The keypad consists of the usual ten digit keys, the normal four direction keys, plus a MENU key that is used to access the configuration menu and a HUSH key that will silence the audible alarm indicators. -
Page 17: Normal Status Display
S h o w In this example, the first digit entered was 1. Since the DVP-120 can handle 12 sensors, the first digit for a sensor number is either 0 or 1. The leading zero must be entered when selecting a sensor less than ten. When the second digit is entered, the normal display will be restored;... -
Page 18: Warning Status Display
A L A R M S I L E N C E D F O R If Relay 1 has be configured as an ALARM relay it will be turned on when an alarm condition is recognized and will be turned off when all audio indicators have been silenced. Silencing applies to the cause(s) of the alarm when the HUSH key is pressed. -
Page 19: Ventilation Control
The ventilation control function operates independently from the alarm function. It provides the ability to configure the DVP-120 for control of one to three zones. Each zone can respond to gas levels indicated by one or more of the three types of sensors, with configurable turn on and turn off concentrations for each gas type. -
Page 20: Setting The System Configuration
While the DVP-120 is in the configuration mode, alarm and ventilation control functions continue in the background with the previously set configuration values. In particular, if an alarm condition is detected the alarm lamp, the buzzer, the horn and the strobe will operate as configured but the LCD will not display the detailed information. -

Page 37: No Power
The DVP-120 starts up as soon as power is applied to the microcontroller, and the DVP-120 is designed to have power continuously applied to the unit. An external indication of successful power application to the unit is the immediate operation of the Status Lamps grouped around the LCD.
