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. System wiring includes the main power connection for the DVP-120, current loop and power connections between

NOTE: ENGINEER AND ARCHITECT SPECIFICATIONS 1. Power connections at the sensor are non-polarized. Gas detection and exhaust fan control is provided by a Macurco DVP-120 2. DVP-120 connections are representative of J7, J8, J10, J11, J13 and J14. system. This System will use CM-2B or CM-3 Carbon Monoxide (CO) to current transducers, ND-2 Nitrogen Dioxide to current transducers or GT- CM-2B GT-11A 11A Combustible Gas to current transducers. Each transducer will measure the level of the target gas

2 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. The panel should be mounted with sufficient space all around, depending on the complexity of the installation. Main power wiring should conform to national and local ele

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. Macurco recommends the use of a ring terminal for the ground connection. Refer to Table 2-1 for DVP-120 power connections. The line and neutral

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. Table 2-3 lists the connector to sensor channel correspondence. While Table 2-4 lists channel signals, connector and termin

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. 1 9 Insert this face of connector into mating connector on control circuit board.

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. 1 4 Insert this face of connector into mating connector on control circuit board. Figure 2-3 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

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. Power connections to Macurco sensors used with the DVP-120 are polarity-insensitive, 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 connecti

3 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.

3.1.2 User Interface The LCD display is used to show detailed information about the status of the control system and the configuration parameters to the user. 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 sile

When the HUSH key is pressed, the internal buzzer will be silenced for eight (8) hours. If the horn or strobe turn on delays have not finished then they will also be silence. If the delays have finished, the HUSH key must be held for three (3) seconds in order 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 five seconds (or any key press), the display will return to normal mode.

3.3 Setting the System Configuration The configuration menus can be entered from normal mode by pressing the MENU key. While in configuration mode, the user can review all configuration parameters to check the current operating conditions. As an aid when configuring the control panel, the first entry in the top menu summarizes the number of sensors and relays that the panel is currently recognizing. 5 S E N S O R S F O U N D 3 R E L A Y S F O U N D Figure 3-14 Hardware Summary
