Fixed Detectors
CX-6/12, CD-6/12, CM-6/12, GD-6/12, TX-6/12-ND, TX-6/12-AM, TX-6/12-HS, OX-6/12, RD-6/12
Commercial Series (6 & 12 series) â The sticker is on the back of the unit (please see image below) *Older units may have the date code sticker on the plastic electrical cover or on the relays along the left side of the board. ** Older units with replaceable sensors (OX&TX) stickers would be located on the sensor.
Locate the white sticker on the unit that has 2 sets of numbers. One set is the part number, and the other is the 8-digit date code. Refer to the following image to obtain the date of manufacture.
Macurco Product date code is in the format of AABCCDDDD where AA is the 2-digit year, B is a Letter corresponding with a month, CC is the day of the month, and D is the calibration Lot code.
It is recommended the detectors be bump-tested on a regular schedule to ensure the sensor is functional; calibrations may be needed to maintain the sensor’s accuracy.
Standalone/Analog Applications: 18/4 stranded (preferably shielded)
Modbus Applications: Power: 18/2, Signal: Use at least 3 conductor wires 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 22 or 24 Gauge.
CM-E1 â Flashing amber / end of life â The CM-E1 will flash an Amber LED once the unit has reached its end of life. This indicator can be reset for 24 hours for 30 days. After 30 days the unit will no longer allow the reset and will need to be replaced.
t200Â â This error code will display on the Macurco 6 & 12 series devices indicating the sensor has reached its end of life. Depending on the model the sensor can be replaced (TX & OX models) or the device will need to be replaced.
t100Â â This error code will display on the Macurco 6 & 12 series devices indicating the sensor is under range or detecting levels less than zero. To clear this code a field calibration will need to be successfully completed on the device.
CCCÂ â This error code will display on the Macurco 6 & 12 series devices when the sensor is over range. Typically, this error will clear once the gas level has returned to levels within range of the sensor.

6 & 12 series â To find the firmware version loaded on your commercial device, disconnect the power either by removing the power terminal from the back of the device or at the power source. When power is reapplied to the unit the display will show the current firmware version prior to starting the warm-up count down
CM-E1, GD-2B, GD-2A, HD-11
CM-E1/GD-2B â The sticker is located on the sounder, a white circular piece between the circuit board and faceplate, visible from the narrow end of the device.
GD-2A/ HD-11 â The sticker is located on the back of the front cover, visible once the cover is removed.
Commercial Series (6 & 12 series) â The sticker is on the back of the unit (please see image below) *Older units may have the date code sticker on the plastic electrical cover or on the relays along the left side of the board. ** Older units with replaceable sensors (OX&TX) stickers would be located on the sensor.

The CM-E1 now has an 8-pin wiring harness vs the 6-pin. Please reference the wiring diagram above or in the user manual for the correct alarm and trouble relay configuration back to the alarm control panel.
Control Panels
DVP-120, DVP-120M, DVP-120B, DVP-120C
DVP-120 â The DVP-120 Control Panel is used for smaller (12 sensors or less) systems. This setup utilizes a 4-conductor home run of wire and an analog 4-20mA communication loop.
DVP-120MÂ â The DVP-120M Control Panel is used for larger (13 â 87 sensors) systems. This setup utilizes a Modbus communication loop over a twisted & shielded cable. The panel supports up to 3 communication loops that can be daisy-chained from sensor to sensor.
DVP-120BÂ â The DVP-120B Control Panel takes the Modbus communication another step with the addition of BACnet output for logging of the system data. This panel will support up to 99 sensors on two Modbus communication loops both terminating on the TB1 terminal.
DVP-120C â The DVP-120C Control Panel is Approved for Title 24 use in California. This panel utilizes the same hardware as the DVP-120B, which supports up to 99 sensors on 2 Modbus communication loops.
Control panels â The sticker is located on the inside of the front panel, and the date code is listed under the serial number.

Please click the video link below for step-by-step instructions on how to set up zones on the Macurco DVP-120 Control Panel.
When the CX-6 is connected to a DVP-120 control panel, the sensor will address by the channel it is connected to for the NO2 sensor and that channel plus 12 for the CO sensor. So, for the CX-6 terminated on C1 of the DVP-120 control panel it will obtain sensor address 01 for NO2 and sensor address 13 for CO.
When the CX-6 is connected to a DVP-120M or DVP120B control panel using the MRS-485, the sensor will obtain the address assigned to the MRS-485 for NO2 and that address plus 1 for CO. So, for the CX-6 connected to an MRS-485 with the address of 13, the NO2 sensor will show as sensor 13 and the CO will show as sensor 14 on the DVP-120M or DVP-120B.
In these systems, it is important to assign addresses to the MRS-485 accordingly, as using duplicate addresses is not allowed. Duplicate addresses will cause the sensor to not show up on the panel.
Once the DVP control panel is wired and powered on, complete these steps to configure your panel:
1) Press the menu button and verify the number of sensors matches the number connected. Troubleshoot any missing sensors.
2) Follow the steps outlined in the DVP Quick Start Guide to add the sensors and relays to zones.
3) Test the configuration by either bump testing sensors or performing a 4-20mA test from the sensor.

There are a few different ways to test the programming and functionality of the relays on the DVP control panels. Running the 4-20mA test from a connected sensor is one of the simplest and best ways. This test simulates gas being applied to the sensor and changes the output from that sensor, testing the connection to the panel as well as the programming that would control the relay on the panel.
To perform the 4-20mA test, follow these steps:
1) Remove the cover from the sensor.
2) Press the Menu button so the display reads âtstâ
3) Press the Next/Enter button
4) Press the Menu/Next button so the display reads â42tâ
5) Press the Next/Enter button to run the test.

DVP Control Panel â The firmware version of the DVP control panel can be found by cycling power to the panel. When power is applied, the display will read the firmware version prior to starting the warmup countdown.
An external power supply is needed for daisy-chain (Modbus) applications.
